                          NOTES TO FINANCIAL STATEMENTS
                                   (Unaudited)


Note A - Basis of Presentation

As of December  31,  1999,  Century  Properties  Fund XX (the  "Partnership"  or
"Registrant") adopted the liquidation basis of accounting.

The  Partnership's  Nonrecourse  Promissory  Notes  (the  "Notes"),  which had a
balance of principal and accrued  interest of  approximately  $1,767,000 at June
30, 2004, matured on November 30, 1998. The notes bear interest at eight percent
per annum. The Partnership was in default due to non-payment upon maturity.  Fox
Capital  Management  Corporation  ("FCMC"  or the  "Managing  General  Partner")
previously  contacted the indenture trustee for the Notes and certain holders of
the Notes regarding this default.  On October 28, 1999, the Partnership  entered
into a  forbearance  agreement  with the  indenture  trustee for a period of 390
days. In turn, the  Partnership  agreed to (a) deliver to the indenture  trustee
for  the  benefit  of  the  note  holders  all of the  accumulated  cash  of the
Partnership,  less certain  reserves and  anticipated  operating  expenses,  (b)
market all of its  properties  for sale,  (c) deliver all cash proceeds from any
sales to the  indenture  trustee  until the Notes  are fully  satisfied  and (d)
comply with the reporting requirements under the indenture. At the expiration of
the  forbearance  period,  the Partnership had not sold all of its properties or
satisfied the Notes. With the consent of the indenture trustee,  the forbearance
period  was  extended  to  December  15,  2001.  The  sale of the  Partnership's
remaining asset in October 2001 did not generate  sufficient proceeds to pay off
the Notes in full. The Managing General Partner is working with the debt trustee
regarding a final  payment to the  noteholders.  Once this payment is made,  the
Partnership is expected to terminate.

As a result of the  decision  to  liquidate  the  Partnership,  the  Partnership
changed its basis of  accounting  for its  financial  statements at December 31,
1999, to the  liquidation  basis of accounting.  Consequently,  assets have been
valued at estimated net realizable  value and liabilities are presented at their
estimated   settlement   amounts.   The  valuation  of  assets  and  liabilities
necessarily  requires many estimates and  assumptions  and there are substantial
uncertainties in carrying out the liquidation.  The actual realization of assets
and  settlement of liabilities  could be higher or lower than amounts  indicated
and is based upon the Managing General Partner's estimates as of the date of the
financial statements.

Included in liabilities in the statement of net liabilities in liquidation as of
June 30,  2004 is  approximately  $89,000  of costs  that the  Managing  General
Partner  estimates will be incurred  during the remaining  period of liquidation
based on the  assumption  that the  liquidation  process  will be  completed  by
December  31,  2004.  Because  the  settlement  of  liabilities  is based on the
Managing General Partner's best estimates, the liquidation period may be shorter
than projected or it may be extended beyond the projected period.

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 certain payments
to affiliates for services and as reimbursement of certain expenses  incurred by
affiliates on behalf of the Partnership.

Affiliates of the Managing  General Partner received no  reimbursements  for the
six months ended June 30, 2004 or 2003.

During the six months ended June 30, 2004, an affiliate of the Managing  General
Partner  advanced  the  Partnership   approximately  $40,000  to  pay  operating
expenses. No interest was charged on this advance.

Note C - Contingencies

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
purported  to  assert  claims  on  behalf  of a class of  limited  partners  and
derivatively  on behalf  of a number  of  limited  partnerships  (including  the
Partnership)  that 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 that 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  sought  monetary
damages and equitable relief, including judicial dissolution of the Partnership.
In addition, 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 Heller action was brought as a
purported derivative action, and asserted claims for, among other things, breach
of fiduciary  duty,  unfair  competition,  conversion,  unjust  enrichment,  and
judicial dissolution.

On January 8, 2003,  the parties filed a  Stipulation  of Settlement in proposed
settlement  of the Nuanes  action and the Heller  action.  The  settlement  only
benefits limited partners as of December 20, 2002 in those limited  partnerships
named in the complaint  that are not in the process of being  liquidated or that
have already been  liquidated.  The  Partnership's  limited partners will not be
entitled to any proceeds from the  settlement  since the  Partnership  is in the
process of being liquidated,  but have not compromised any potential claims as a
result of the settlement  and  dismissal.  The  Partnership's  limited  partners
should have received a Notice to  Non-Settling  Persons  during April 2003 which
describes this information in more detail.

On June 13, 2003, the Court granted final approval of the settlement and entered
judgment in both the Nuanes and Heller actions.  On August 12, 2003, an objector
filed an appeal  seeking  to vacate  and/or  reverse  the  order  approving  the
settlement  and  entering  judgment  thereto.  On April 23,  2004,  the Managing
General  Partner  and its  affiliates  filed a response  brief in support of the
settlement  and the  judgment  thereto.  Plaintiffs  have also  filed a brief in
support of the  settlement.  Objector  filed a reply  brief on June 4, 2004.  No
hearing has been scheduled in this matter.

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

As  previously  disclosed,  the  Central  Regional  Office of the United  States
Securities and Exchange  Commission is conducting an  investigation  relating to
certain  matters.  AIMCO  believes the areas of  investigation  include  AIMCO's
miscalculated   monthly  net  rental  income  figures  in  third  quarter  2003,
forecasted  guidance,  accounts payable,  rent concessions,  vendor rebates, and
capitalization of expenses and payroll.  AIMCO is cooperating  fully. AIMCO does
not believe that the ultimate outcome will have a material adverse effect on its
consolidated  financial  condition  or results of  operations  taken as a whole.
Similarly,  the  Managing  General  Partner  does not believe  that the ultimate
outcome  will have a  material  adverse  effect on the  Partnership's  financial
condition or results of operations taken as a whole.

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

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.  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;  litigation,  including  costs  associated  with  prosecuting  and
defending claims and any adverse  outcomes.  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.

As of December  31,  1999,  Century  Properties  Fund XX (the  "Partnership"  or
"Registrant")  adopted the liquidation  basis of accounting.  The  Partnership's
Nonrecourse Promissory Notes (the "Notes"), which had a balance of principal and
accrued  interest  of  approximately  $1,767,000  at June 30,  2004,  matured on
November  30,  1998.  The notes bear  interest at eight  percent per annum.  The
Partnership  was in  default  due to  non-payment  upon  maturity.  Fox  Capital
Management  Corporation  ("FCMC" or the "Managing General  Partner")  previously
contacted the indenture  trustee for the Notes and certain  holders of the Notes
regarding  this default.  On October 28, 1999,  the  Partnership  entered into a
forbearance  agreement  with the indenture  trustee for a period of 390 days. In
turn,  the  Partnership  agreed to (a) deliver to the indenture  trustee for the
benefit of the note holders all of the accumulated cash of the Partnership, less
certain  reserves  and  anticipated  operating  expenses,  (b) market all of its
properties  for  sale,  (c)  deliver  all cash  proceeds  from any  sales to the
indenture  trustee  until the Notes are fully  satisfied and (d) comply with the
reporting requirements under the indenture. At the expiration of the forbearance
period,  the  Partnership  had not sold all of its  properties  or satisfied the
Notes.  With the consent of the indenture  trustee,  the forbearance  period was
extended to December 15, 2001. The sale of the Partnership's  remaining asset in
October 2001 did not generate  sufficient proceeds to pay off the Notes in full.
The Managing General Partner is working with the debt trustee  regarding a final
payment to the  noteholders.  Once this  payment  is made,  the  Partnership  is
expected to terminate.

As a result of the  decision  to  liquidate  the  Partnership,  the  Partnership
changed its basis of  accounting  for its  financial  statements at December 31,
1999 to the  liquidation  basis of  accounting.  Consequently,  assets have been
valued at estimated net realizable  value and liabilities are presented at their
estimated   settlement   amounts.   The  valuation  of  assets  and  liabilities
necessarily  requires many estimates and  assumptions  and there are substantial
uncertainties in carrying out the liquidation.  The actual realization of assets
and  settlement of liabilities  could be higher or lower than amounts  indicated
and is based upon the Managing General Partner's estimates as of the date of the
financial statements.

During  the six  months  ended  June 30,  2004,  net  liabilities  increased  by
approximately  $95,000. The increase is due to increases in the accrued interest
payable on the Notes and in amounts due to affiliate  and a decrease in the debt
trustee  escrow  partially  offset  by a  decrease  in  other  liabilities.  The
estimated costs during the period of liquidation increased due to an increase in
the expected legal and administrative expenses incurred by the trustee on behalf
of the Partnership.

During  the six  months  ended  June 30,  2003,  net  liabilities  increased  by
approximately  $60,000.  This  increase is  primarily  due to an increase in the
accrued  interest  payable  on  the  non-recourse  promissory  notes  and in the
estimated costs during the period of liquidation  partially offset by a decrease
in other  liabilities.  The increase in the estimated costs during the period of
liquidation is due to an increase in the estimate for the annual audit.

Included in other liabilities in the statement of net liabilities in liquidation
as of June 30, 2004 is approximately  $89,000 of costs that the Managing General
Partner estimates will be incurred during the period of liquidation based on the
assumption that the liquidation  process will be completed by December 31, 2004.
Because the settlement of liabilities is based on the Managing General Partner's
best estimates,  the liquidation  period may be shorter than projected or it may
be extended beyond the projected period.

In light of the maturity of the Notes, no distributions were made to the limited
partners for the six months ended June 30, 2004 and 2003.

In addition to its indirect  ownership of the Managing  General Partner interest
in the  Partnership,  AIMCO and its affiliates  owned 3,950 limited  partnership
units in the Partnership representing 6.39% of the outstanding units at June 30,
2004. AIMCO and its affiliates also own 8,977 of the notes representing 9.10% of
the outstanding notes at June 30, 2004.

ITEM 3.     CONTROLS AND PROCEDURES

(a) Disclosure Controls and Procedures.  The Partnership's management,  with the
participation of 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,  has
evaluated  the  effectiveness  of  the  Partnership's  disclosure  controls  and
procedures (as such term is defined in Rules  13a-15(e) and 15d-15(e)  under the
Securities  Exchange Act of 1934, as amended (the "Exchange Act")) as of the end
of the period covered by this report.  Based on such  evaluation,  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 concluded that, as of the
end of such period,  the  Partnership's  disclosure  controls and procedures are
effective.

(b) Internal Control Over Financial  Reporting.  There have not been any changes
in the Partnership's  internal control over financial reporting (as such term is
defined in Rules  13a-15(f)  and  15d-15(f)  under the Exchange  Act) during the
fiscal quarter to which this report relates that have  materially  affected,  or
are reasonably likely to materially affect,  the Partnership's  internal control
over financial reporting.

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
