                         MARCH 31, 2006

                           (Unaudited)

(1)  The  condensed  statements included herein have been  prepared
     by  the Partnership, without audit, pursuant to the rules  and
     regulations  of  the Securities and Exchange  Commission,  and
     reflect   all  adjustments  which  are,  in  the  opinion   of
     management,  necessary to a fair statement of the  results  of
     operations for the interim period, on a basis consistent  with
     the  annual audited statements.  The adjustments made to these
     condensed   statements  consist  only  of   normal   recurring
     adjustments.   Certain information, accounting  policies,  and
     footnote    disclosures   normally   included   in   financial
     statements  prepared  in  accordance with  generally  accepted
     accounting principles have been condensed or omitted  pursuant
     to  such  rules  and  regulations,  although  the  Partnership
     believes  that  the  disclosures  are  adequate  to  make  the
     information  presented not misleading.  It is  suggested  that
     these  condensed financial statements be read  in  conjunction
     with  the  financial statements and the summary of significant
     accounting  policies  and  notes  thereto  included   in   the
     Partnership's latest annual report on Form 10-KSB.

     Partners  contributed  funds  of  $22,783,050,  and  $1,000,
     respectively.

     During operations, any Net Cash Flow, as defined, which  the
     General Partners determine to distribute will be distributed
     90% to the Limited Partners and 10% to the General Partners;
     provided,  however, that such distributions to  the  General
     Partners will be subordinated to the Limited Partners  first
     receiving an annual, noncumulative distribution of Net  Cash
     Flow equal to 10% of their Adjusted Capital Contribution, as
     defined,  and, provided further, that in no event  will  the
     General Partners receive less than 1% of such Net Cash  Flow
     per  annum. Distributions to Limited Partners will  be  made
     pro rata by Units.

(2)  Organization - (Continued)

     Any  Net  Proceeds  of Sale as defined,  from  the  sale  or
     financing of properties which the General Partners determine
     to distribute will, after provisions for debts and reserves,
     be  paid  in  the following manner:  (i) first, 99%  to  the
     Limited  Partners and l% to the General Partners  until  the
     Limited  Partners  receive an amount  equal  to:  (a)  their
     Adjusted Capital Contribution plus (b) an amount equal to 6%
     of their Adjusted Capital Contribution per annum, cumulative
     but not compounded, to the extent not previously distributed
     from  Net  Cash Flow; (ii) next, 99% to the Limited Partners
     and  1%  to the General Partners until the Limited  Partners
     receive  an  amount equal to 14% of their  Adjusted  Capital
     Contribution  per annum, cumulative but not  compounded,  to
     the  extent not previously distributed; (iii) next,  to  the
     General  Partners  until  cumulative  distributions  to  the
     General  Partners under Items (ii) and (iii)  equal  15%  of
     cumulative  distributions to all Partners under  Items  (ii)
     and (iii).  Any remaining balance will be distributed 85% to
     the  Limited  Partners  and  15% to  the  General  Partners.
     Distributions to the Limited Partners will be made pro  rata
     by Units.

     For  tax  purposes,  profits  from  operations,  other  than
     profits  attributable  to  the  sale,  exchange,  financing,
     refinancing  or  other  disposition  of  property,  will  be
     allocated  first  in the same ratio in  which,  and  to  the
     extent,  Net  Cash Flow is distributed to the  Partners  for
     such year.  Any additional profits will be allocated 90%  to
     the Limited Partners and 10% to the General Partners. In the
     event  no  Net  Cash  Flow  is distributed  to  the  Limited
     Partners,  90%  of each item of income, gain or  credit  for
     each  respective  year  shall be allocated  to  the  Limited
     Partners,  and 10% of each such item shall be  allocated  to
     the  General Partners.  Net losses from operations  will  be
     allocated 98% to the Limited Partners and 2% to the  General
     Partners.

     For  tax purposes, profits arising from the sale, financing,
     or  other  disposition  of property  will  be  allocated  in
     accordance  with the Partnership Agreement as  follows:  (i)
     first,  to  those  partners with deficit balances  in  their
     capital  accounts  in an amount equal to  the  sum  of  such
     deficit  balances; (ii) second, 99% to the Limited  Partners
     and  1%  to the General Partners until the aggregate balance
     in  the Limited Partners' capital accounts equals the sum of
     the Limited Partners' Adjusted Capital Contributions plus an
     amount  equal to 14% of their Adjusted Capital Contributions
     per  annum, cumulative but not compounded, to the extent not
     previously  allocated; (iii) third, to the General  Partners
     until  cumulative allocations to the General Partners  equal
     15%  of cumulative allocations.  Any remaining balance  will
     be  allocated  85% to the Limited Partners and  15%  to  the
     General  Partners.   Losses will be  allocated  98%  to  the
     Limited Partners and 2% to the General Partners.

     The  General Partners are not required to currently  fund  a
     deficit   capital   balance.   Upon   liquidation   of   the
     Partnership or withdrawal by a General Partner, the  General
     Partners will contribute to the Partnership an amount  equal
     to  the  lesser  of  the deficit balances in  their  capital
     accounts  or  1%  of  total Limited  Partners'  and  General
     Partners' capital contributions.

(3)  Reclassification -

     Certain items in the prior year's financial statements  have
     been  reclassified  to conform to 2006 presentation.   These
     reclassifications  had no effect on Partners'  capital,  net
     income or cash flows.

(4)  Investments in Real Estate -

     In February 2004, Garden Ridge, L.P. (GR), the tenant of the
     Garden  Ridge  retail store in Woodlands, Texas,  filed  for
     Chapter 11 bankruptcy reorganization.  In press releases, GR
     reported rejecting the leases of 9 of 44 stores and that  it
     was  attempting  to renegotiate lease terms  for  its  other
     stores.   The Woodlands store was not identified as  one  of
     the  nine  to be closed.  GR entered into negotiations  with
     the  property owners of the Woodlands store to arrive at  an
     agreement  to  modify rental terms that would induce  GR  to
     affirm  the  Lease for this property.  GR and  the  property
     owners  subsequently agreed to a lease amendment  to  reduce
     the  annual rent by 23%, with a 10% rent increase on January
     1,  2008.  The Partnership's share of the new rental  amount
     is  $175,968.  The amendment provides for additional  rental
     payments if the store's sales exceed certain stated amounts.
     The  amendment also calls for the owners to waive  rent  for
     one   month  during  the  first  six  months  following  the
     bankruptcy  court's  approval of  GR's  affirmation  of  the
     Lease.   With  the exception of February 2004, GR  made  all
     rental payments due under its original lease.

     On  April 28, 2005, the bankruptcy court approved GR's  Plan
     of  Reorganization.  As part of the Plan, the lease for  the
     Woodlands  store was affirmed by GR and the lease  amendment
     became  effective.  Pursuant to the amendment,  GR  selected
     July  2005  as  the one month to have rent waived.   In  May
     2005,  GR  paid the rent due for February 2004 and, pursuant
     to  the amendment, GR was entitled to credit an equal amount
     against  any  installment of rent due  in  the  future.   GR
     applied  the credit for the February rent against  rent  due
     for  August  and  September 2005.  As of the  date  of  this
     report, GR has complied with all Lease terms as amended.

(5)  Payable to AEI Fund Management -

     AEI  Fund  Management, Inc. performs the administrative  and
     operating functions for the Partnership.  The payable to AEI
     Fund   Management  represents  the  balance  due  for  those
     services.    This  balance  is  non-interest   bearing   and
     unsecured  and  is  to  be  paid in  the  normal  course  of
     business.

(6)  Discontinued Operations -

     In  July  2003,  the  tenant of the Razzoo's  restaurant  in
     Alpharetta,  Georgia notified the Partnership  that  it  was
     experiencing financial difficulty stemming from  lower  than
     expected  sales and that it might not be able to pay  future
     rents.   In late 2003, the tenant closed the restaurant  and
     said  that it no longer intended to operate a restaurant  at
     the  site.  The Partnership and the tenant entered  into  an
     agreement,  effective  November 1, 2004,  to  terminate  the
     lease   and  return  possession  of  the  property  to   the
     Partnership.   Rents  were  current  through  the  date   of
     termination.  As part of the agreement, the Partnership  was
     reimbursed for certain expenses it incurred related to legal
     action  it  pursued in connection with this situation.   The
     Partnership listed the property for sale with a real  estate
     broker  in  the  Alpharetta area.  While  the  property  was
     vacant,  the  Partnership was responsible  for  real  estate
     taxes and other costs required to maintain the property.

     Based  on an analysis of market conditions in the area,  the
     Partnership   determined  the  property  was   impaired   in
     accordance  with the requirements of Statement of  Financial
     Accounting  Standards No. 144, Accounting for the Impairment
     or  Disposal  of  Long-Lived Assets.  As a  result,  in  the
     fourth  quarter of 2003, a charge to discontinued operations
     for real estate impairment of $252,399 was recognized, which
     was  the  difference between the book value at December  31,
     2003  of  $852,399 and the estimated fair value of $600,000.
     The  charge  was  recorded against the  cost  of  the  land,
     building and equipment.

     In  December 2004, the Partnership entered into an agreement
     to  sell  the  property in Alpharetta to an unrelated  third
     party.   On  March  29,  2005,  the  sale  closed  with  the
     Partnership  receiving net sale proceeds of $648,425,  which
     resulted in a net gain of $48,425.

     On  May  31, 2005, the Partnership sold its 5.8291% interest
     in  the  Applebee's  restaurant in Destin,  Florida  to  the
     tenant.   The  Partnership received  net  sale  proceeds  of
     $109,804, which resulted in a net gain of $62,281.  The cost
     and  related  accumulated depreciation of the interest  sold
     was $65,215 and $17,692, respectively.

     During  the third quarter of 2005, the Partnership sold  its
     50% interest in the Johnny Carino's restaurant in Mansfield,
     Texas,  in  three separate transactions, to unrelated  third
     parties.   The Partnership received total net sale  proceeds
     of  $1,490,853,  which resulted in a net gain  of  $506,543.
     The   cost  and  related  accumulated  depreciation  of  the
     interests sold was $1,028,886 and $44,576, respectively.

     On  October  18, 2005, the Partnership sold the Old  Country
     Buffet  restaurant in Northlake, Illinois  to  an  unrelated
     third party.  The Partnership received net sale proceeds  of
     $1,973,839,  which resulted in a net gain of  $851,215.   At
     the   time   of  sale,  the  cost  and  related  accumulated
     depreciation was $1,350,804 and $228,180, respectively.

(6)  Discontinued Operations - (Continued)

     In  October 2005, the Partnership entered into an  agreement
     to  sell  its  50% interest in the Applebee's restaurant  in
     Stow,  Ohio  to an unrelated third party.  On  November  15,
     2005,  the  sale closed with the Partnership  receiving  net
     sale proceeds of $1,835,784, which resulted in a net gain of
     $310,234.   At  the  time  of sale,  the  cost  and  related
     accumulated   depreciation  was  $1,575,755   and   $50,205,
     respectively.

     In  May  2003, the Partnership entered into an agreement  to
     sell  a Taco Cabana restaurant in San Antonio, Texas to  the
     tenant.  The agreement was extended several times to  enable
     the  tenant  to  complete their due  diligence  and  certain
     negotiations with adjacent land owners.  During  this  time,
     the tenant continued to pay rent and complied with the lease
     obligations.  On January 26, 2006, the sale closed with  the
     Partnership receiving net sale proceeds of $1,642,624, which
     resulted  in a net gain of $484,970.  At the time  of  sale,
     the cost and related accumulated depreciation was $1,406,426
     and  $248,772,  respectively.  At  December  31,  2005,  the
     property was classified as Real Estate Held for Sale with  a
     book value of $1,157,654.

     During  the  first  three  months  of  2006  and  2005,  the
     Partnership distributed $1,736,394 and $58,074 of  net  sale
     proceeds  to  the Limited and General Partners  as  part  of
     their quarterly distributions, which represented a return of
     capital  of  $90.21 and $2.99 per Limited Partnership  Unit,
     respectively.

     The financial results for these properties are reflected  as
     Discontinued   Operations  in  the  accompanying   financial
     statements.   The following are the results of  discontinued
     operations for the three months ended March 31:

ITEM 2.MANAGEMENT'S DISCUSSION AND ANALYSIS

        The Management's Discussion and Analysis contains various
"forward  looking  statements"  within  the  meaning  of  federal
securities  laws  which  represent management's  expectations  or
beliefs  concerning future events, including statements regarding
anticipated  application of cash, expected  returns  from  rental
income,  growth  in revenue, taxation levels, the sufficiency  of
cash to meet operating expenses, rates of distribution, and other
matters.  These, and other forward looking statements made by the
Partnership,  must be evaluated in the context  of  a  number  of
factors that may affect the Partnership's financial condition and
results of operations, including the following:

    Market  and  economic conditions which affect the  value
    of  the  properties the Partnership owns and  the  cash
    from rental income such properties generate;

    the  federal  income tax consequences of rental  income,
    deductions,  gain  on  sales and other  items  and  the
    affects of these consequences for the Partners;

    resolution  by  the General Partners of  conflicts  with
    which they may be confronted;

    the   success   of  the  General  Partners   of   locating
    properties with favorable risk return characteristics;

    the effect of tenant defaults; and

    the  condition of the industries in which the  tenants  of
    properties owned by the Partnership operate.

The Application of Critical Accounting Policies

        The preparation of the Partnership's financial statements
requires  management to make estimates and assumptions  that  may
affect the reported amounts of assets, liabilities, revenues  and
expenses,  and  related  disclosure  of  contingent  assets   and
liabilities. Management evaluates these estimates on  an  ongoing
basis,  including  those related to the carrying  value  of  real
estate  and  the  allocation  by AEI  Fund  Management,  Inc.  of
expenses  to  the  Partnership as opposed  to  other  funds  they
manage.

        The Partnership purchases properties and records them  in
the  financial  statements  at the lower  of  cost  or  estimated
realizable   value.   The  Partnership  initially   records   the
properties  at cost (including capitalized acquisition expenses).
The Partnership is required to periodically evaluate the carrying
value  of properties to determine whether their realizable  value
has  declined.   For  properties the Partnership  will  hold  and
operate, management determines whether impairment has occurred by
comparing the property's probability-weighted cash flows  to  its
current carrying value.  For properties held for sale, management
determines  whether  impairment has  occurred  by  comparing  the
property's estimated fair value less cost to sell to its  current
carrying  value.   If  the carrying value  is  greater  than  the
realizable  value, an impairment loss is recorded to  reduce  the
carrying value of the property to its realizable value.  A change
in  these assumptions or analysis could cause material changes in
the carrying value of the properties.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS.  (Continued)

        AEI  Fund Management, Inc. allocates expenses to each  of
the  funds  they manage primarily on the basis of the  number  of
hours  devoted  by their employees to each fund's affairs.   They
also  allocate  expenses at the end of each month  that  are  not
directly related to a fund's operations based upon the number  of
investors  in the fund and the fund's capitalization relative  to
other  funds  they  manage.   The  Partnership  reimburses  these
expenses  subject  to  detailed  limitations  contained  in   the
Partnership Agreement.

         Management   of  the  Partnership  has   discussed   the
development  and selection of the above accounting estimates  and
the management discussion and analysis disclosures regarding them
with the managing partner of the Partnership.

Results of Operations

        For  the three months ended March 31, 2006 and 2005,  the
Partnership  recognized rental income from continuing  operations
of $287,582 and $286,135, respectively.

        For  the three months ended March 31, 2006 and 2005,  the
Partnership  incurred  Partnership administration  expenses  from
affiliated  parties of $35,292 and $54,651, respectively.   These
administration  expenses  include  costs  associated   with   the
management of the properties, processing distributions, reporting
requirements and correspondence to the Limited Partners.  As  the
Partnership's asset base decreases due to property sales,  it  is
allocated a smaller share of expenses that are allocated  by  AEI
Fund  Management, Inc. based on the relative assets of the  funds
under  management.   During  the same  periods,  the  Partnership
incurred   Partnership  administration  and  property  management
expenses   from  unrelated  parties  of  $10,024   and   $12,574,
respectively.  These expenses represent direct payments to  third
parties  for legal and filing fees, direct administrative  costs,
outside audit costs, taxes, insurance and other property costs.

        In February 2004, Garden Ridge, L.P. (GR), the tenant  of
the  Garden  Ridge  retail store in Woodlands, Texas,  filed  for
Chapter  11  bankruptcy reorganization.  In  press  releases,  GR
reported rejecting the leases of 9 of 44 stores and that  it  was
attempting to renegotiate lease terms for its other stores.   The
Woodlands  store  was not identified as one of  the  nine  to  be
closed.  GR entered into negotiations with the property owners of
the  Woodlands  store to arrive at an agreement to modify  rental
terms that would induce GR to affirm the Lease for this property.
GR  and  the  property  owners subsequently  agreed  to  a  lease
amendment  to  reduce the annual rent by 23%,  with  a  10%  rent
increase on January 1, 2008.  The Partnership's share of the  new
rental amount is $175,968.  The amendment provides for additional
rental  payments  if  the  store's sales  exceed  certain  stated
amounts.   The amendment also calls for the owners to waive  rent
for   one  month  during  the  first  six  months  following  the
bankruptcy  court's approval of GR's affirmation  of  the  Lease.
With  the exception of February 2004, GR made all rental payments
due under its original lease.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS.  (Continued)

       On April 28, 2005, the bankruptcy court approved GR's Plan
of  Reorganization.   As  part of the Plan,  the  lease  for  the
Woodlands store was affirmed by GR and the lease amendment became
effective.  Pursuant to the amendment, GR selected July  2005  as
the one month to have rent waived.  In May 2005, GR paid the rent
due  for  February  2004 and, pursuant to the amendment,  GR  was
entitled  to  credit an equal amount against any  installment  of
rent  due  in the future.  GR applied the credit for the February
rent  against rent due for August and September 2005.  As of  the
date  of  this  report, GR has complied with all Lease  terms  as
amended.

        For  the three months ended March 31, 2006 and 2005,  the
Partnership  recognized interest income of  $25,763  and  $4,167,
respectively.  In 2006, interest income increased mainly  due  to
the  Partnership  having more money invested in  a  money  market
account due to property sales.

        In  accordance  with  Statement of  Financial  Accounting
Standards  No. 144, Accounting for the Impairment or Disposal  of
Long-Lived  Assets,  upon  complete disposal  of  a  property  or
classification of a property as Real Estate Held  for  Sale,  the
Partnership  includes  the operating  results  and  sale  of  the
property   in   discontinued  operations.    In   addition,   the
Partnership reclassifies the prior periods operating results  and
any  partial  sales  of the property to discontinued  operations.
For  the  three  months  ended March 31,  2006,  the  Partnership
recognized  income  from  discontinued  operations  of  $501,918,
representing rental income less property management  expenses  of
$16,948 and gain on disposal of real estate of $484,970.  For the
three  months  ended  March 31, 2005, the Partnership  recognized
income  from  discontinued operations of  $180,361,  representing
rental  income less property management expenses and depreciation
of $131,936 and gain on disposal of real estate of $48,425.

        In  July  2003, the tenant of the Razzoo's restaurant  in
Alpharetta,  Georgia  notified  the  Partnership  that   it   was
experiencing  financial  difficulty  stemming  from  lower   than
expected sales and that it might not be able to pay future rents.
In  late 2003, the tenant closed the restaurant and said that  it
no  longer  intended to operate a restaurant at  the  site.   The
Partnership  and the tenant entered into an agreement,  effective
November 1, 2004, to terminate the lease and return possession of
the  property to the Partnership.  Rents were current through the
date  of  termination.  As part of the agreement, the Partnership
was  reimbursed for certain expenses it incurred related to legal
action  it  pursued in connection with this situation.  Following
an  analysis  of the tenant's business at this location  and  its
financial condition, and its intent to no longer operate at  this
site,  the Partnership determined that the best course of  action
was to negotiate a settlement with the tenant and take possession
of   the   property.   With  possession  of  the  property,   the
Partnership  could  move forward with selling  the  property  and
reinvesting  the  proceeds from the sale in  replacement  income-
producing property.  The Partnership listed the property for sale
with  a  real  estate broker in the Alpharetta area.   While  the
property  was  vacant, the Partnership was responsible  for  real
estate taxes and other costs required to maintain the property.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS.  (Continued)

       Based on an analysis of market conditions in the area, the
Partnership  determined the property was impaired  in  accordance
with  the  requirements  of  Statement  of  Financial  Accounting
Standards  No. 144, Accounting for the Impairment or Disposal  of
Long-Lived Assets.  As a result, in the fourth quarter of 2003, a
charge  to discontinued operations for real estate impairment  of
$252,399  was  recognized, which was the difference  between  the
book  value  at  December 31, 2003 of $852,399 and the  estimated
fair value of $600,000.  The charge was recorded against the cost
of the land, building and equipment.

         In  December  2004,  the  Partnership  entered  into  an
agreement  to  sell the property in Alpharetta  to  an  unrelated
third  party.   On  March  29, 2005, the  sale  closed  with  the
Partnership  receiving  net  sale  proceeds  of  $648,425,  which
resulted in a net gain of $48,425.

       On May 31, 2005, the Partnership sold its 5.8291% interest
in  the  Applebee's restaurant in Destin, Florida to the  tenant.
The  Partnership  received net sale proceeds of  $109,804,  which
resulted  in  a  net  gain  of $62,281.   The  cost  and  related
accumulated  depreciation of the interest sold  was  $65,215  and
$17,692, respectively.

       During the third quarter of 2005, the Partnership sold its
50%  interest  in  the Johnny Carino's restaurant  in  Mansfield,
Texas,  in  three  separate  transactions,  to  unrelated   third
parties.   The  Partnership received total net sale  proceeds  of
$1,490,853, which resulted in a net gain of $506,543.   The  cost
and  related accumulated depreciation of the interests  sold  was
$1,028,886 and $44,576, respectively.

        On October 18, 2005, the Partnership sold the Old Country
Buffet  restaurant in Northlake, Illinois to an  unrelated  third
party.  The Partnership received net sale proceeds of $1,973,839,
which  resulted in a net gain of $851,215.  At the time of  sale,
the  cost and related accumulated depreciation was $1,350,804 and
$228,180, respectively.

       In October 2005, the Partnership entered into an agreement
to  sell  its 50% interest in the Applebee's restaurant in  Stow,
Ohio to an unrelated third party.  On November 15, 2005, the sale
closed  with  the  Partnership receiving  net  sale  proceeds  of
$1,835,784,  which resulted in a net gain of  $310,234.   At  the
time  of sale, the cost and related accumulated depreciation  was
$1,575,755 and $50,205, respectively.

        In May 2003, the Partnership entered into an agreement to
sell  a  Taco  Cabana  restaurant in San Antonio,  Texas  to  the
tenant.   The agreement was extended several times to enable  the
tenant  to  complete their due diligence and certain negotiations
with   adjacent  land  owners.   During  this  time,  the  tenant
continued  to  pay rent and complied with the lease  obligations.
On  January  26,  2006,  the  sale closed  with  the  Partnership
receiving  net sale proceeds of $1,642,624, which resulted  in  a
net  gain of $484,970.  At the time of sale, the cost and related
accumulated    depreciation   was   $1,406,426   and    $248,772,
respectively.  At December 31, 2005, the property was  classified
as Real Estate Held for Sale with a book value of $1,157,654.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS.  (Continued)

        In the second quarter of 2005, the Partnership decided to
discontinue the reinvestment of proceeds from property  sales  in
additional  properties.   As a result, the  Partnership's  rental
income  and operating income will decrease in the future  as  the
Partnership sells its remaining properties.

        Inflation  has  had  a  minimal  effect  on  income  from
operations.   Leases  may contain rent increases,  based  on  the
increase  in  the  Consumer Price Index over a specified  period,
which  will result in an increase in rental income over the  term
of  the  leases.   In addition, leases may contain  rent  clauses
which  entitle  the  Partnership to receive  additional  rent  in
future  years  if gross receipts for the property exceed  certain
specified  amounts.  Increases in sales volumes of  the  tenants,
due to inflation and real sales growth, may result in an increase
in rental income over the term of the leases.  Inflation also may
cause the real estate to appreciate in value.  However, inflation
and  changing prices may have an adverse impact on the  operating
margins  of  the  properties' tenants, which could  impair  their
ability  to  pay rent and subsequently reduce the Net  Cash  Flow
available for distributions.

Liquidity and Capital Resources

        During  the  three  months  ended  March  31,  2006,  the
Partnership's cash balances decreased $1,761,628 as a  result  of
distributions  paid to the Partners in excess of  cash  generated
from operating and investing activities.  During the three months
ended  March 31, 2005, the Partnership's cash balances  increased
$409,499 as a result of cash generated from the sale of property,
which  was partially offset by distributions paid to the Partners
in excess of cash generated from operating activities.

        Net  cash provided by operating activities decreased from
$521,545  in 2005 to $238,391 in 2006 due to a decrease in  total
rental and interest income in 2006 and net timing differences  in
the  collection  of  payments from lessees  and  the  payment  of
expenses,   which  were  partially  offset  by  a   decrease   in
Partnership  administration and property management  expenses  in
2006.

       During the three months ended March 31, 2006 and 2005, the
Partnership generated cash flow from the sale of real  estate  of
$1,642,624 and $648,425, respectively.

       The Partnership's primary use of cash flow is distribution
and  redemption  payments to Partners.  The Partnership  declares
its  regular  quarterly  distributions before  the  end  of  each
quarter and pays the distribution in the first week after the end
of  each quarter.  The Partnership attempts to maintain a  stable
distribution  rate from quarter to quarter.  Redemption  payments
are paid to redeeming Partners on a quarterly basis.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS.  (Continued)

        For  the three months ended March 31, 2006 and 2005,  the
Partnership  declared distributions of $2,002,740  and  $378,370,
respectively, which were distributed 99% to the Limited  Partners
and  1%  to the General Partners.  The Limited Partners  received
distributions of $1,982,712 and $374,586 and the General Partners
received  distributions of $20,028 and $3,784  for  the  periods,
respectively.   In  June,  September  and  December   2005,   the
Partnership   declared   special   distributions   of   $505,051,
$1,515,152  and  $3,282,828, respectively, of net sale  proceeds,
which  resulted in a higher distribution payable at December  31,
2005.    In  March  2006,  the  Partnership  declared  a  special
distribution  of $1,717,172 of net sale proceeds, which  resulted
in  higher distributions for the first three months of 2006, when
compared to the first three months of 2005.

        During  the  first  three months of 2006  and  2005,  the
Partnership  distributed  $1,736,394  and  $58,074  of  net  sale
proceeds  to  the Limited and General Partners as part  of  their
quarterly distributions, which represented a return of capital of
$90.21 and $2.99 per Limited Partnership Unit, respectively.

        The  Partnership may acquire Units from Limited  Partners
who have tendered their Units to the Partnership.  Such Units may
be  acquired at a discount.  The Partnership is not obligated  to
purchase  in  any  year  more than 5%  of  the  number  of  Units
outstanding at the beginning of the year.  In no event shall  the
Partnership  be  obligated to purchase  Units  if,  in  the  sole
discretion  of the Managing General Partner, such purchase  would
impair the capital or operation of the Partnership.

       On January 1, 2006, four Limited Partners redeemed a total
of  27  Partnership  Units for $18,444  in  accordance  with  the
Partnership  Agreement.   On  January  1,  2005,  twelve  Limited
Partners redeemed a total of 85.75 Partnership Units for $77,457.
The  Partnership acquired these Units using Net  Cash  Flow  from
operations.   In  prior  years, a total of 266  Limited  Partners
redeemed   3,438.67  Partnership  Units  for   $2,858,329.    The
redemptions  increase the remaining Limited  Partners'  ownership
interest  in  the  Partnership.  As a result of these  redemption
payments  and pursuant to the Partnership Agreement, the  General
Partners  received distributions of $186 and  $783  in  2006  and
2005, respectively.

       The continuing rent payments from the properties, together
with  cash  generated from property sales, should be adequate  to
fund   continuing   distributions  and  meet  other   Partnership
obligations on both a short-term and long-term basis.

ITEM 3. CONTROLS AND PROCEDURES.

       (a) Evaluation of disclosure controls and procedures

        Under  the  supervision  and with  the  participation  of
management, including its President and Chief Financial  Officer,
the  Managing  General Partner of the Partnership  evaluated  the
effectiveness  of  the  design and operation  of  its  disclosure
controls  and procedures (as defined in Rule 13a-14(c) under  the
Exchange  Act).   Based upon that evaluation, the  President  and
Chief Financial Officer of the Managing General Partner concluded
that,  as  of  the end of the period covered by this report,  the
disclosure  controls  and  procedures  of  the  Partnership   are
adequately  designed to ensure that information  required  to  be
disclosed  by  us  in  the reports we file or  submit  under  the
Exchange  Act  is recorded, processed, summarized  and  reported,
within the time periods specified in applicable rules and forms.

       (b)  Changes in internal controls

         There   were   no  significant  changes  made   in   the
Partnership's  internal controls during the  most  recent  period
covered  by  this  report that have materially affected,  or  are
reasonably   likely  to  materially  affect,  the   Partnership's
internal control over financial reporting.
