The issuer  recently  discovered  that it had  inadvertently  omitted  conformed
signatures on certain certifications included in its 10-QSB filing made November
14, 2002.  Original  signatures were complete and on file with the issuer at the
time the 10-QSB filing was made in November;  however,  due to a clerical error,
conformed  signatures were not included in the electronic filing. This amendment
is being filed solely to correct this inadvertent clerical error.

                          NOTES TO FINANCIAL STATEMENTS
                                   (Unaudited)


Note A - Basis of Presentation

The accompanying unaudited financial statements of National Property Investors 4
(the  "Partnership" or the  "Registrant")  have been prepared in accordance with
generally accepted accounting  principles for interim financial  information and
with  the  instructions  to Form  10-QSB  and Item  310(b)  of  Regulation  S-B.
Accordingly,  they do not include all of the information and footnotes  required
by generally accepted accounting  principles for complete financial  statements.
In the opinion of NPI Equity Investments, Inc. (the "Managing General Partner"),
all adjustments  (consisting of normal recurring accruals)  considered necessary
for a fair presentation have been included.  Operating results for the three and
nine month periods ended September 30, 2002, are not  necessarily  indicative of
the results that may be expected  for the fiscal year ending  December 31, 2002.
For further information, refer to the financial statements and footnotes thereto
included in the  Partnership's  Annual Report on Form 10-KSB for the fiscal year
ended  December  31,  2001.  The Managing  General  Partner is a  subsidiary  of
Apartment  Investment and Management Company  ("AIMCO"),  a publicly traded real
estate investment trust.

Effective  April 1, 2002, the  Partnership  adopted SFAS No. 145,  "Recission of
FASB  Statements No. 4, 44 and 64." SFAS No. 4 "Reporting  Gains and Losses from
Extinguishment of Debt," required that all gains and losses from  extinguishment
of debt be aggregated  and, if material,  classified as an  extraordinary  item.
SFAS No.  145  rescinds  SFAS No.  4, and  accordingly,  gains and  losses  from
extinguishment  of debt should only be classified as  extraordinary  if they are
unusual in nature and occur  infrequently.  Neither of these criteria applies to
the Partnership.  As a result,  the  accompanying  statements of operations have
been restated as of January 1, 2001 to reflect the loss on early  extinguishment
of debt of approximately  $169,000 at Village of Pennbrook Apartments (see "Note
C") in operations rather than as an extraordinary item.

Note B - Transactions with Affiliated Parties

The  Partnership  has no employees  and is  dependent  on the  Managing  General
Partner  and  its  affiliates  for  the  management  and  administration  of all
partnership  activities.  The  Partnership  Agreement  provides  for payments to
affiliates for services and for  reimbursement of certain  expenses  incurred by
affiliates on behalf of the Partnership.

Affiliates of the Managing  General  Partner are entitled to receive 5% of gross
receipts  from the  Partnership's  property for  providing  property  management
services.  The Partnership  paid to such affiliates  approximately  $285,000 and
$281,000  for the  nine  month  periods  ended  September  30,  2002  and  2001,
respectively, which is included in operating expenses.

Affiliates  of  the  Managing   General  Partner  received   reimbursements   of
accountable  administrative  expenses  amounting to  approximately  $146,000 and
$159,000  for the  nine  month  periods  ended  September  30,  2002  and  2001,
respectively,  which are  included  in general  and  administrative  expense and
investment   properties.   Included  in  these   amounts  are  fees  related  to
construction  management  services  provided  by an  affiliate  of the  Managing
General  Partner of  approximately  $6,000 and $33,000 for the nine months ended
September 30, 2002 and 2001,  respectively.  The construction management service
fees are calculated based on a percentage of current additions to the investment
property.

For services relating to the  administration of the Partnership and operation of
the Partnership's  property, the Managing General Partner is entitled to receive
payment for non-accountable  expenses up to a maximum of $100,000 per year based
upon the number of Partnership units sold, subject to certain  limitations.  The
Managing  General  Partner  received  payment  for  non-accountable  expenses of
approximately $53,000 and $100,000 during the nine month periods ended September
30,   2002  and  2001,   respectively,   which  are   included  in  general  and
administrative expense.

In  addition  to the amounts  discussed  above,  as  compensation  for  services
rendered in managing the  Partnership,  the Managing General Partner is entitled
to receive Partnership management fees in conjunction with distributions of cash
from operations,  subject to certain limitations.  During the nine month periods
ended  September  30,  2002  and  2001,   approximately   $39,000  and  $46,000,
respectively, was paid in conjunction with the distributions from operations and
are included in general and  administrative  expense.  An additional $28,000 was
paid  during the nine months  ended  September  30,  2002 which was  included in
accounts payable at December 31, 2001 and general and administrative expense for
the quarter ended December 31, 2001.

The Partnership Agreement also provides for a commission to the Managing General
Partner  for  its  role  in  the  refinancing  of the  Partnership's  investment
property.  During the nine months ended September 30, 2001, the Partnership paid
a commission of approximately  $304,000 related to the refinancing of Village of
Pennbrook Apartments in August 2001. Such fee was capitalized and is included in
other assets.

The Managing  General  Partner has made available to the  Partnership a $300,000
line of credit. At the present time, the Partnership has no outstanding  amounts
due under this line of credit.

Beginning in 2001,  the  Partnership  began  insuring its property up to certain
limits through coverage provided by AIMCO which is generally  self-insured for a
portion of losses and  liabilities  related  to workers  compensation,  property
casualty and vehicle liability.  The Partnership  insures its property above the
AIMCO  limits  through  insurance  policies  obtained  by  AIMCO  from  insurers
unaffiliated  with the Managing  General  Partner.  During the nine months ended
September  30,  2002 and 2001,  the  Partnership  was  charged  by AIMCO and its
affiliates  approximately  $64,000  and  $70,000,  respectively,  for  insurance
coverage and fees associated with policy claims administration.

Note C - Mortgage Refinancing

On August 31,  2001,  the  Partnership  refinanced  the  mortgage  note  payable
encumbering Village of Pennbrook  Apartments.  The refinancing replaced mortgage
indebtedness of $19,300,000 with a new mortgage of $30,400,000. The new mortgage
carries a stated  interest  rate of 7.01%  compared to a stated rate of 7.33% on
the old  mortgage.  Payments of principal  and interst are due monthly until the
loan matures in  September  2021 at which time the loan is scheduled to be fully
amortized.  Loan  costs  capitalized  for  the  refinancing  were  approximately
$854,000,  including  a $304,000  refinancing  fee paid to an  affiliate  of the
Managing General Partner pursuant to the Partnership Agreement.  The Partnership
recorded a loss on early  extinguishment of debt of approximately  $169,000 as a
result of unamortized loan costs being written off.

Note D - Legal Proceedings

In March 1998, several putative unit holders of limited partnership units of the
Partnership  commenced an action  entitled  Rosalie  Nuanes,  et al. v. Insignia
Financial Group, Inc., et al. (the "Nuanes action") in the Superior Court of the
State of  California  for the  County  of San  Mateo.  The  plaintiffs  named as
defendants,  among others,  the  Partnership,  its Managing  General Partner and
several of their  affiliated  partnerships  and corporate  entities.  The action
purports  to  assert  claims  on  behalf  of a class  of  limited  partners  and
derivatively  on behalf  of a number  of  limited  partnerships  (including  the
Partnership)  which are named as nominal  defendants,  challenging,  among other
things,  the  acquisition  of  interests  in certain  Managing  General  Partner
entities by Insignia Financial Group, Inc. ("Insignia") and entities which were,
at one  time,  affiliates  of  Insignia;  past  tender  offers  by the  Insignia
affiliates to acquire limited partnership units;  management of the partnerships
by the  Insignia  affiliates;  and the series of  transactions  which  closed on
October 1, 1998 and February 26, 1999 whereby  Insignia and Insignia  Properties
Trust,  respectively,  were merged  into AIMCO.  The  plaintiffs  seek  monetary
damages and equitable relief, including judicial dissolution of the Partnership.
On June 25, 1998, the Managing General Partner filed a motion seeking  dismissal
of the action.  In lieu of responding  to the motion,  the  plaintiffs  filed an
amended  complaint.  The Managing General Partner filed demurrers to the amended
complaint which were heard February 1999.

Pending the ruling on such  demurrers,  settlement  negotiations  commenced.  On
November 2, 1999,  the parties  executed and filed a Stipulation  of Settlement,
settling claims, subject to court approval, on behalf of the Partnership and all
limited partners who owned units as of November 3, 1999. Preliminary approval of
the  settlement  was obtained on November 3, 1999 from the Court,  at which time
the Court set a final  approval  hearing for  December  10,  1999.  Prior to the
December  10,  1999  hearing,  the  Court  received  various  objections  to the
settlement, including a challenge to the Court's preliminary approval based upon
the alleged lack of authority of prior lead counsel to enter the settlement.  On
December 14, 1999, the Managing  General  Partner and its affiliates  terminated
the  proposed  settlement.  In  February  2000,  counsel  for some of the  named
plaintiffs filed a motion to disqualify plaintiff's lead and liaison counsel who
negotiated  the  settlement.  On June  27,  2000,  the  Court  entered  an order
disqualifying  them  from the case and an  appeal  was  taken  from the order on
October 5, 2000. On December 4, 2000, the Court  appointed the law firm of Lieff
Cabraser  Heimann & Bernstein  LLP as new lead  counsel for  plaintiffs  and the
putative class.  Plaintiffs filed a third amended complaint on January 19, 2001.
On March 2, 2001,  the  Managing  General  Partner  and its  affiliates  filed a
demurrer to the third amended  complaint.  On May 14, 2001,  the Court heard the
demurrer to the third amended  complaint.  On July 10, 2001, the Court issued an
order  sustaining  defendants'  demurrer on certain  grounds.  On July 20, 2001,
Plaintiffs filed a motion for reconsideration of the Court's July 10, 2001 order
granting in part and denying in part defendants' demurrer. On September 7, 2001,
Plaintiffs  filed a fourth amended class and  derivative  action  complaint.  On
September 12, 2001, the Court denied Plaintiffs' motion for reconsideration.  On
October 5, 2001, the Managing General Partner and affiliated  defendants filed a
demurrer to the fourth amended complaint,  which was heard on December 11, 2001.
On February 2, 2002,  the Court served its order  granting in part the demurrer.
The  Court has  dismissed  without  leave to amend  certain  of the  plaintiffs'
claims.  On February 11, 2002,  plaintiffs  filed a motion  seeking to certify a
putative  class  comprised of all  non-affiliated  persons who own or have owned
units  in  the  partnerships.   The  Managing  General  Partner  and  affiliated
defendants  oppose the motion.  On April 29,  2002,  the Court held a hearing on
plaintiffs' motion for class  certification and took the matter under submission
after further  briefing,  as ordered by the court, was submitted by the parties.
On July 10, 2002,  the Court entered an order vacating the current trial date of
January 13, 2003 (as well as the  pre-trial  and  discovery  cut-off  dates) and
stayed the case in its entirety through November 7, 2002 so that the parties can
have an  opportunity  to discuss  settlement.  On October  30,  2002,  the court
entered an order extending the stay in effect through January 10, 2003.

During the third  quarter of 2001, a complaint  (the "Heller  action") was filed
against  the same  defendants  that are named in the  Nuanes  action,  captioned
Heller v. Insignia Financial Group. On or about August 6, 2001, plaintiffs filed
a first amended  complaint.  The first amended complaint in the Heller action is
brought as a purported  derivative  action,  and asserts  claims for among other
things  breach  of  fiduciary  duty;  unfair  competition;   conversion,  unjust
enrichment;  and judicial  dissolution.  Plaintiffs in the Nuanes action filed a
motion to  consolidate  the Heller action with the Nuanes action and stated that
the Heller action was filed in order to preserve the derivative claims that were
dismissed  without  leave to amend in the Nuanes action by the Court order dated
July 10, 2001. On October 5, 2001, the Managing  General  Partner and affiliated
defendants  moved to strike the first  amended  complaint  in its  entirety  for
violating  the Court's July 10, 2001 order  granting in part and denying in part
defendants'  demurrer in the Nuanes action, or alternatively,  to strike certain
portions of the complaint based on the statute of limitations.  Other defendants
in the action  demurred to the fourth  amended  complaint,  and,  alternatively,
moved to strike the complaint. On December 11, 2001, the court heard argument on
the motions  and took the matters  under  submission.  On February 4, 2002,  the
Court  served  notice of its order  granting  defendants'  motion to strike  the
Heller complaint as a violation of its July 10, 2001 order in the Nuanes action.
On March 27, 2002,  the plaintiffs  filed a notice  appealing the order striking
the complaint. The parties are currently in the midst of briefing that appeal.

Estate of Harry  Schubert v.  National  Property  Investors  4, Civil Action No.
97-09129, Court of Common Pleas of Bucks County, Pennsylvania.  During 1998, the
Plaintiff brought action against the Partnership  alleging that as the result of
carbon monoxide and methane  poisoning due to a malfunctioning  heat unit in the
apartment at the Partnership's property, which was leased by decedent's son, the
decedent lost consciousness for several hours,  suffered respiratory arrest, and
suffered  other pains and injuries.  The Plaintiff  alleges  breach of contract,
fraud,  violations of the Unfair Trade Practices and Consumer Protection Law and
negligence  resulting  in wrongful  death.  This matter is in the  discovery  of
litigation. The Partnership is vigorously defending this matter.

The Managing  General Partner does not anticipate that any costs,  whether legal
or  settlement  costs,  associated  with  these  cases will be  material  to the
Partnership's overall operations.

The  Partnership is unaware of any other pending or outstanding  litigation that
is not of a routine nature arising in the ordinary course of business.

ITEM 2.     MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

The Private  Securities  Litigation  Reform Act of 1995 provides a "safe harbor"
for forward-looking  statements in certain circumstances.  The matters discussed
in this report contain certain forward-looking  statements,  including,  without
limitation,  statements regarding future financial performance and the effect of
government regulations. The discussions of the Registrant's business and results
of operations,  including forward-looking statements pertaining to such matters,
do not take into account the effects of any changes to the Registrant's business
and  results of  operations.  Actual  results may differ  materially  from those
described in the forward-looking statements and will be affected by a variety of
risks and factors  including,  without  limitation:  national and local economic
conditions; the terms of governmental regulations that affect the Registrant and
interpretations of those regulations;  the competitive  environment in which the
Registrant  operates;  financing risks,  including the risk that cash flows from
operations  may be  insufficient  to meet  required  payments of  principal  and
interest;  real estate risks, including variations of real estate values and the
general  economic  climate in local markets and  competition for tenants in such
markets; and possible environmental liabilities. Readers should carefully review
the Registrant's financial statements and the notes thereto, as well as the risk
factors  described in the documents the Registrant  files from time to time with
the Securities and Exchange Commission.

The Partnership's investment property consists of one apartment complex, Village
of Pennbrook Apartments,  located in Falls Township,  Pennsylvania.  The average
occupancy was 96% for both of the nine month  periods  ended  September 30, 2002
and 2001.

Results of Operations

Effective  April 1, 2002, the  Partnership  adopted SFAS No. 145,  "Recission of
FASB  Statements No. 4, 44 and 64." SFAS No. 4 "Reporting  Gains and Losses from
Extinguishment of Debt," required that all gains and losses from  extinguishment
of debt be aggregated  and, if material,  classified as an  extraordinary  item.
SFAS No.  145  rescinds  SFAS No.  4, and  accordingly,  gains and  losses  from
extinguishment  of debt should only be classified as  extraordinary  if they are
unusual  in  nature  and  occur  infrequently.  As a  result,  the  accompanying
statements of operations have been restated as of January 1, 2001 to reflect the
loss on early  extinguishment  of debt of  approximately  $169,000 at Village of
Pennbrook Apartments in operations rather than as an extraordinary item.

The Partnership  realized net income of approximately  $855,000 and $826,000 for
the nine months ended September 30, 2002 and 2001, respectively. The increase in
net income for the nine months ended  September 30, 2002 is  attributable  to an
increase in total revenues  partially  offset by an increase in total  expenses.
Total  revenues  increased  due to an  increase  in rental  income  caused by an
increase in average rental rates at the Partnership's  investment property.  The
increase in total  expenses was due to  increases  in interest and  depreciation
expenses   partially   offset  by  decreases   in  operating   and  general  and
administrative  expenses and the loss on early  extinguishment of debt. Interest
expense increased due to the refinancing of the mortgage  encumbering Village of
Pennbrook  Apartments  in August 2001 which  resulted in a higher  average  debt
balance in 2002 (see "Capital Resources and Liquidity" for further  discussion).
Depreciation  expense  increased due to property  improvements  and replacements
placed  into  service  during  the  past  twelve  months  which  are  now  being
depreciated. The decrease in operating expense is primarily due to a decrease in
natural  gas  expense at the  Partnership's  investment  property.  General  and
administrative  expense  decreased  primarily  due to a decrease in  partnership
management fees and non-accountable reimbursements associated with distributions
from operations.  The loss on early extinguishment of debt recognized during the
nine months ended  September 30, 2001 was due to the refinancing of the mortgage
encumbering the Partnership's investment property in August 2001.

The Partnership  realized net income of approximately  $330,000 and $186,000 for
the three months ended September 30, 2002 and 2001,  respectively.  The increase
in net income for the three months ended September 30, 2002 is attributable to a
decrease in total  expenses.  The decrease in total expenses was due to the loss
on early  extinguishment  of debt  recognized  during  the  three  months  ended
September 30, 2001 and a decrease in operating  expense  partially  offset by an
increase in interest expense, as discussed above.

Included  in general  and  administrative  expenses  are  reimbursements  to the
Managing General Partner allowed under the Partnership Agreement associated with
its  management  of the  Partnership.  Costs  associated  with the quarterly and
annual  communications  with investors and regulatory  agencies,  and the annual
audit required by the Partnership Agreement are also included.

As part of the ongoing  business plan of the  Partnership,  the Managing General
Partner  monitors the rental market  environment of its  investment  property to
assess the feasibility of increasing rents,  maintaining or increasing occupancy
levels and protecting  the  Partnership  from increases in expenses.  As part of
this plan, the Managing General Partner attempts to protect the Partnership from
the burden of  inflation-related  increases in expenses by increasing  rents and
maintaining a high overall  occupancy  level.  However,  due to changing  market
conditions,  which  can  result  in the use of  rental  concessions  and  rental
reductions to offset softening market conditions, there is no guarantee that the
Managing General Partner will be able to sustain such a plan.

Capital Resources and Liquidity

At  September  30,  2002,  the  Partnership  had cash and  cash  equivalents  of
approximately  $85,000 as compared to  approximately  $200,000 at September  30,
2001. For the nine months ended  September 30, 2002,  cash and cash  equivalents
decreased  approximately  $290,000 from December 31, 2001. This decrease was due
to approximately $1,910,000 and $327,000 of cash used in financing and investing
activities,  respectively,  partially offset by approximately $1,947,000 of cash
provided by operating activities. Cash used in financing activities consisted of
distributions paid to the partners and payments made on the mortgage encumbering
Village of Pennbrook Apartments.  Cash used in investing activities consisted of
property  improvements  and  replacements.  The Partnership  invests its working
capital reserves in interest bearing accounts.

The Managing  General Partner has extended to the Partnership a $300,000 line of
credit.  At the present time, the  Partnership  has no  outstanding  amounts due
under this line of credit.  Based on present plans, the Managing General Partner
does not anticipate  the need to borrow in the near future.  Other than cash and
cash equivalents,  the line of credit is the Partnership's only unused source of
liquidity.

The sufficiency of existing  liquid assets to meet future  liquidity and capital
expenditure   requirements   is  directly   related  to  the  level  of  capital
expenditures required at the property to adequately maintain the physical assets
and other operating  needs of the Partnership and to comply with Federal,  state
and local  legal and  regulatory  requirements.  The  Managing  General  Partner
monitors  developments  in the area of legal and  regulatory  compliance  and is
studying  new  federal  laws,  including  the  Sarbanes-Oxley  Act of 2002.  The
Sarbanes-Oxley Act of 2002 mandates or suggests  additional  compliance measures
with regard to governance,  disclosure, audit and other areas. In light of these
changes,  the Partnership  expects that it will incur higher expenses related to
compliance,  including  increased  legal and audit  fees.  Capital  improvements
planned for the Partnership's investment property are detailed below.

Approximately  $316,000 has been budgeted for capital improvements at Village of
Pennbrook  Apartments  during  the  year  2002,  consisting  primarily  of floor
covering replacements,  structural improvements,  parking lot resurfacing, water
heater  replacements and appliances.  During the nine months ended September 30,
2002,  the  Partnership  completed   approximately   $327,000  of  budgeted  and
unbudgeted capital  improvements at Village of Pennbrook  Apartments  consisting
primarily  of floor  covering,  water  heater and  appliance  replacements,  air
conditioning upgrades and maintenance equipment. These capital improvements were
funded from operating cash flows.  Additional improvements may be considered and
will depend on the physical  condition  of the  property as well as  anticipated
cash flows generated by the property.  The capital improvements will be incurred
only if cash is available from operations or from Partnership  reserves.  To the
extent that such budgeted capital improvements are completed,  the Partnership's
distributable cash flow, if any, may be adversely affected at least in the short
term.

The Partnership's  current assets are thought to be sufficient for any near-term
needs  (exclusive  of capital  improvements)  of the  Partnership.  The mortgage
indebtedness of  approximately  $29,678,000 is being amortized over 20 years and
will mature in  September  2021 at which time the  mortgage is  scheduled  to be
fully amortized.

On August 31,  2001,  the  Partnership  refinanced  the  mortgage  note  payable
encumbering Village of Pennbrook  Apartments.  The refinancing replaced mortgage
indebtedness of $19,300,000 with a new mortgage of $30,400,000. The new mortgage
carries a stated  interest  rate of 7.01%  compared to a stated rate of 7.33% on
the old mortgage.

Pursuant to the Partnership Agreement,  the term of the Partnership is scheduled
to expire on December 31, 2005. Accordingly,  prior to such date the Partnership
will need to  either  sell its  investment  property  or extend  the term of the
Partnership.

The Partnership  distributed the following  amounts during the nine months ended
September 30, 2002 and 2001 (in thousands, except per unit data):

</TABLE>

(1) From the refinancing of Village of Pennbrook Apartments in August 2001.

The  Partnership's  cash  available  for  distribution  is reviewed on a monthly
basis. Future cash distributions will depend on the levels of net cash generated
from operations,  the availability of cash reserves,  and the timing of the debt
maturity,  refinancing, and/or property sale. There can be no assurance that the
Partnership  will  generate  sufficient  funds from  operations  after  required
capital improvements to permit further  distributions to its partners during the
remainder of 2002 or subsequent periods.

Other

In addition to its  indirect  ownership of the general  partner  interest in the
Partnership,  AIMCO and its affiliates  owned 45,293 limited  partnership  units
(the "Units") in the Partnership representing 75.48% of the outstanding Units at
September  30,  2002. A number of these Units were  acquired  pursuant to tender
offers  made by  AIMCO  or its  affiliates.  It is  possible  that  AIMCO or its
affiliates will acquire additional units of limited partnership  interest in the
Partnership  in  exchange  for cash or a  combination  of cash and  units in the
operating  partnership  of AIMCO  either  through  private  purchases  or tender
offers. Under the Partnership  Agreement,  unitholders holding a majority of the
Units are  entitled to take action  with  respect to a variety of matters  which
would  include  voting on certain  amendments to the  Partnership  Agreement and
voting to remove the Managing General  Partner.  As a result of its ownership of
75.48% of the  outstanding  Units,  AIMCO is in a position to influence all such
voting  decisions with respect to the Registrant.  With respect to 26,466 units,
Insignia Properties,  LP, an affiliate of AIMCO, is required to vote such Units:
(i) against any increase in compensation payable to the Managing General Partner
or to  affiliates;  and  (ii)  on  all  other  matters  submitted  by it or  its
affiliates, in proportion to the votes cast by non-tendering unitholders. Except
for the  foregoing,  no other  limitations  are  imposed on AIMCO's or  Insignia
Properties,  L.P.'s  ability to influence  voting  decisions with respect to the
Partnership.  Although the Managing General Partner owes fiduciary duties to the
limited  partners of the  Partnership,  the Managing  General  Partner also owes
fiduciary duties to AIMCO as its sole  stockholder.  As a result,  the duties of
the Managing  General Partner,  as managing general partner,  to the Partnership
and its limited  partners may come into conflict with the duties of the Managing
General Partner to AIMCO, as its sole stockholder.

Critical Accounting Policies and Estimates

The financial  statements are prepared in accordance with accounting  principles
generally  accepted in the United States which require the  Partnership  to make
estimates and  assumptions.  The  Partnership  believes that of its  significant
accounting  policies,  the following may involve a higher degree of judgment and
complexity.

Impairment of Long-Lived Assets

The  Partnership's  investment  property is recorded at cost,  less  accumulated
depreciation,  unless considered impaired.  If events or circumstances  indicate
that the carrying amount of the property may be impaired,  the Partnership  will
make an assessment of its  recoverability by estimating the undiscounted  future
cash flows,  excluding interest charges, of the property. If the carrying amount
exceeds the aggregate  future cash flows,  the  Partnership  would  recognize an
impairment  loss to the extent the carrying amount exceeds the fair value of the
property.

Real  property  investments  are  subject  to varying  degrees of risk.  Several
factors  may  adversely  affect  the  economic  performance  and  value  of  the
Partnership's   investment  property.  These  factors  include  changes  in  the
national,  regional and local economic  climate;  local  conditions,  such as an
oversupply  of  multifamily   properties;   competition   from  other  available
multifamily  property  owners and changes in market  rental  rates.  Any adverse
changes in these factors could cause an impairment in the Partnership's asset.

Revenue Recognition

The Partnership generally leases apartment units for twelve-month terms or less.
Rental income  attributable to leases is recognized monthly as it is earned. The
Partnership will offer rental concessions during  particularly slow months or in
response  to  heavy  competition  from  other  similar  complexes  in the  area.
Concessions are charged to income as incurred.

ITEM 3.     CONTROLS AND PROCEDURES

The principal  executive officer and principal financial officer of the Managing
General Partner, who are the equivalent of the Partnership's principal executive
officer and principal financial officer,  respectively,  have, within 90 days of
the filing date of this quarterly  report,  evaluated the  effectiveness  of the
Partnership's  disclosure  controls and  procedures  (as defined in Exchange Act
Rules  (13a-14(c)  and  (15d-14(c))  and have  determined  that such  disclosure
controls and procedures are adequate.  There have been no significant changes in
the Partnership's internal controls or in other factors that could significantly
affect the  Partnership's  internal  controls since the date of evaluation.  The
Partnership does not believe any significant deficiencies or material weaknesses
exist in the Partnership's internal controls. Accordingly, no corrective actions
have been taken.

                           PART II - OTHER INFORMATION


ITEM 1.     LEGAL PROCEEDINGS

In March 1998, several putative unit holders of limited partnership units of the
Partnership  commenced an action  entitled  Rosalie  Nuanes,  et al. v. Insignia
Financial Group, Inc., et al. (the "Nuanes action") in the Superior Court of the
State of  California  for the  County  of San  Mateo.  The  plaintiffs  named as
defendants,  among others,  the  Partnership,  its Managing  General Partner and
several of their  affiliated  partnerships  and corporate  entities.  The action
purports  to  assert  claims  on  behalf  of a class  of  limited  partners  and
derivatively  on behalf  of a number  of  limited  partnerships  (including  the
Partnership)  which are named as nominal  defendants,  challenging,  among other
things,  the  acquisition  of  interests  in certain  Managing  General  Partner
entities by Insignia Financial Group, Inc. ("Insignia") and entities which were,
at one  time,  affiliates  of  Insignia;  past  tender  offers  by the  Insignia
affiliates to acquire limited partnership units;  management of the partnerships
by the  Insignia  affiliates;  and the series of  transactions  which  closed on
October 1, 1998 and February 26, 1999 whereby  Insignia and Insignia  Properties
Trust,  respectively,  were merged  into AIMCO.  The  plaintiffs  seek  monetary
damages and equitable relief, including judicial dissolution of the Partnership.
On June 25, 1998, the Managing General Partner filed a motion seeking  dismissal
of the action.  In lieu of responding  to the motion,  the  plaintiffs  filed an
amended  complaint.  The Managing General Partner filed demurrers to the amended
complaint which were heard February 1999.

Pending the ruling on such  demurrers,  settlement  negotiations  commenced.  On
November 2, 1999,  the parties  executed and filed a Stipulation  of Settlement,
settling claims, subject to court approval, on behalf of the Partnership and all
limited partners who owned units as of November 3, 1999. Preliminary approval of
the  settlement  was obtained on November 3, 1999 from the Court,  at which time
the Court set a final  approval  hearing for  December  10,  1999.  Prior to the
December  10,  1999  hearing,  the  Court  received  various  objections  to the
settlement, including a challenge to the Court's preliminary approval based upon
the alleged lack of authority of prior lead counsel to enter the settlement.  On
December 14, 1999, the Managing  General  Partner and its affiliates  terminated
the  proposed  settlement.  In  February  2000,  counsel  for some of the  named
plaintiffs filed a motion to disqualify plaintiff's lead and liaison counsel who
negotiated  the  settlement.  On June  27,  2000,  the  Court  entered  an order
disqualifying  them  from the case and an  appeal  was  taken  from the order on
October 5, 2000. On December 4, 2000, the Court  appointed the law firm of Lieff
Cabraser  Heimann & Bernstein  LLP as new lead  counsel for  plaintiffs  and the
putative class.  Plaintiffs filed a third amended complaint on January 19, 2001.
On March 2, 2001,  the  Managing  General  Partner  and its  affiliates  filed a
demurrer to the third amended  complaint.  On May 14, 2001,  the Court heard the
demurrer to the third amended  complaint.  On July 10, 2001, the Court issued an
order  sustaining  defendants'  demurrer on certain  grounds.  On July 20, 2001,
Plaintiffs filed a motion for reconsideration of the Court's July 10, 2001 order
granting in part and denying in part defendants' demurrer. On September 7, 2001,
Plaintiffs  filed a fourth amended class and  derivative  action  complaint.  On
September 12, 2001, the Court denied Plaintiffs' motion for reconsideration.  On
October 5, 2001, the Managing General Partner and affiliated  defendants filed a
demurrer to the fourth amended complaint,  which was heard on December 11, 2001.
On February 2, 2002,  the Court served its order  granting in part the demurrer.
The  Court has  dismissed  without  leave to amend  certain  of the  plaintiffs'
claims.  On February 11, 2002,  plaintiffs  filed a motion  seeking to certify a
putative  class  comprised of all  non-affiliated  persons who own or have owned
units  in  the  partnerships.   The  Managing  General  Partner  and  affiliated
defendants  oppose the motion.  On April 29,  2002,  the Court held a hearing on
plaintiffs' motion for class  certification and took the matter under submission
after further  briefing,  as ordered by the court, was submitted by the parties.
On July 10, 2002,  the Court entered an order vacating the current trial date of
January 13, 2003 (as well as the  pre-trial  and  discovery  cut-off  dates) and
stayed the case in its entirety through November 7, 2002 so that the parties can
have an  opportunity  to discuss  settlement.  On October  30,  2002,  the court
entered an order extending the stay in effect through January 10, 2003.

During the third  quarter of 2001, a complaint  (the "Heller  action") was filed
against  the same  defendants  that are named in the  Nuanes  action,  captioned
Heller v. Insignia Financial Group. On or about August 6, 2001, plaintiffs filed
a first amended  complaint.  The first amended complaint in the Heller action is
brought as a purported  derivative  action,  and asserts  claims for among other
things  breach  of  fiduciary  duty;  unfair  competition;   conversion,  unjust
enrichment;  and judicial  dissolution.  Plaintiffs in the Nuanes action filed a
motion to  consolidate  the Heller action with the Nuanes action and stated that
the Heller action was filed in order to preserve the derivative claims that were
dismissed  without  leave to amend in the Nuanes action by the Court order dated
July 10, 2001. On October 5, 2001, the Managing  General  Partner and affiliated
defendants  moved to strike the first  amended  complaint  in its  entirety  for
violating  the Court's July 10, 2001 order  granting in part and denying in part
defendants'  demurrer in the Nuanes action, or alternatively,  to strike certain
portions of the complaint based on the statute of limitations.  Other defendants
in the action  demurred to the fourth  amended  complaint,  and,  alternatively,
moved to strike the complaint. On December 11, 2001, the court heard argument on
the motions  and took the matters  under  submission.  On February 4, 2002,  the
Court  served  notice of its order  granting  defendants'  motion to strike  the
Heller complaint as a violation of its July 10, 2001 order in the Nuanes action.
On March 27, 2002,  the plaintiffs  filed a notice  appealing the order striking
the complaint. The parties are currently in the midst of briefing that appeal.

Estate of Harry  Schubert v.  National  Property  Investors  4, Civil Action No.
97-09129, Court of Common Pleas of Bucks County, Pennsylvania.  During 1998, the
Plaintiff brought action against the Partnership  alleging that as the result of
carbon monoxide and methane  poisoning due to a malfunctioning  heat unit in the
apartment at the Partnership's property, which was leased by decedent's son, the
decedent lost consciousness for several hours,  suffered respiratory arrest, and
suffered  other pains and injuries.  The Plaintiff  alleges  breach of contract,
fraud,  violations of the Unfair Trade Practices and Consumer Protection Law and
negligence  resulting  in wrongful  death.  This matter is in the  discovery  of
litigation. The Partnership is vigorously defending this matter.

The Managing  General Partner does not anticipate that any costs,  whether legal
or  settlement  costs,  associated  with  these  cases will be  material  to the
Partnership's overall operations.
