                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)


Note A - Basis of Presentation

The accompanying  unaudited consolidated financial statements of Winthrop Growth
Investors 1 Limited  Partnership (the  "Partnership" or "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.  The general partner of the Partnership is AIMCO/Winthrop
Growth Investors I, GP, LLC, a Delaware limited liability company ("AIMCO GP" or
the "Managing General Partner"), a wholly-owned  subsidiary of AIMCO Properties,
L.P., an affiliate of Apartment  Investment and Management Company ("AIMCO"),  a
publicly  traded real estate  investment  trust.  In the opinion of 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 six months  ended June 30,  2005 are not  necessarily
indicative  of the  results  that may be  expected  for the fiscal  year  ending
December 31, 2005. For further information,  refer to the consolidated financial
statements and footnotes thereto included in the Partnership's  Annual Report on
Form 10-KSB for the fiscal year ended December 31, 2004.

On September  30, 2004,  AIMCO/Winthrop  Growth  Investors I GP, LLC, a Delaware
limited  liability  company  acquired  the  general  partner  interests  in  the
Partnership  from  Linnaeus-Lexington  Associates  Limited  Partnership  and Two
Winthrop  Properties,  Inc. ("Two Winthrop") for an aggregate cash consideration
of  $1,023,000.  Prior to the  transfer  of the  general  partner  interests  to
AIMCO/GP,  AIMCO/NHP Properties, Inc. ("AIMCO/NHP"),  also an affiliate of AIMCO
held 100% of the voting  rights with respect to the Class B stock of FWC,  which
provided  AIMCO/NHP  with the  right  to  elect  one  director  to the  board of
directors of Two  Winthrop.  That one director had the power to appoint the sole
member of the Residential  Committee of Two Winthrop's  board of directors.  The
Residential  Committee was vested with the authority to elect certain  officers,
and subject to certain limitations,  the Residential Committee and its appointed
officers had the right to cause the managing  general partner of the Partnership
to take such actions as it deemed necessary and advisable in connection with the
activities of the Partnership.  Accordingly,  although  ownership of the general
partner  interests  was  transferred,  the effective  control of the  day-to-day
management of the  Partnership  remains vested in an affiliate of AIMCO. As used
herein,  the term  "Managing  General  Partner"  shall mean Two  Winthrop,  with
respect  to  matters  occurring  prior to  September  30,  2004 and AIMCO GP for
matters occurring from and after September 30, 2004.

As a result of the sale of Stratford  Place  Apartments  to a third party during
the six months ended June 30, 2005 and in accordance with Statement of Financial
Accounting  Standards  ("SFAS")  No.  144,  "Accounting  for the  Impairment  or
Disposal of Long-Lived  Assets",  the  accompanying  consolidated  statements of
operations  for the three and six months ended June 30, 2004 have been  restated
as of January 1, 2004 to reflect the operations of Stratford Place Apartments as
income from discontinued operations of approximately $98,000 and $75,000 for the
three and six months ended June 30, 2004,  respectively,  including  revenues of
approximately $849,000 and $1,641,000, respectively.







Note B - Transactions with Affiliated Parties

The Partnership has no employees and depends 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 receive 5% of gross receipts from the
Partnership's  properties  as  compensation  for providing  property  management
services.  The Partnership  paid to such affiliates  approximately  $136,000 and
$147,000 during the six months ended June 30, 2005 and 2004, respectively, which
is  included  in  operating   expenses  and  (loss)  income  from   discontinued
operations.

Affiliates  of  the  Managing   General  Partner  charged  the  Partnership  for
reimbursement of accountable  administrative expenses amounting to approximately
$139,000  and  $63,000  for the  six  months  ended  June  30,  2005  and  2004,
respectively  which is  included  in general  and  administrative  expenses  and
investment  properties.   The  portion  of  these  reimbursements   included  in
investment  properties  are fees  related to  construction  management  services
provided  by an  affiliate  of the  Managing  General  Partner of  approximately
$68,000  and  $4,000  for  the  six  months   ended  June  30,  2005  and  2004,
respectively. The construction management service fees are calculated based on a
percentage of certain additions to investment properties.

During the six months ended June 30, 2005 and in accordance with the Partnership
Agreement, an affiliate of the Managing General Partner advanced the Partnership
approximately  $90,000 to fund the payment of real estate  taxes at Ashton Ridge
Apartments.  Interest  was  charged at the prime rate plus 2% (8.25% at June 30,
2005) and was less than  $1,000 for the six  months  ended  June 30,  2005.  The
advance and associated accrued interest was repaid by the Partnership during the
same period.

The  Partnership  insures its properties 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,   general
liability and vehicle  liability.  The Partnership  insures its properties above
the AIMCO limits  through  insurance  policies  obtained by AIMCO from  insurers
unaffiliated with the Managing General Partner. During the six months ended June
30,  2005 and 2004,  the  Partnership  was  charged by AIMCO and its  affiliates
approximately $37,000 and $72,000, respectively, for insurance coverage and fees
associated with policy claims administration.

Note D - Sale of Investment Property

On May 17, 2005, the  Partnership  sold Stratford Place  Apartments,  located in
Gaithersburg,  Maryland,  to a third party for  $29,000,000.  After  payment and
accrual of closing  costs,  the net sales proceeds  received by the  Partnership
were approximately  $28,052,000.  The Partnership used a portion of the proceeds
to repay the mortgage encumbering the property of approximately $8,008,000.  The
sale  resulted  in a gain  on  sale  of  investment  property  of  approximately
$22,064,000  during  the six  months  ended  June 30,  2005.  In  addition,  the
Partnership  recorded a loss on early  extinguishment  of debt of  approximately
$283,000  as a  result  of  prepayment  penalties  paid  and  the  write  off of
unamortized  loan costs,  which is included in (loss)  income from  discontinued
operations. Included in (loss) income from discontinued operations for the three
months ended June 30, 2005 and 2004 are results of the property's  operations of
approximately   $70,000  and  $98,000,   respectively,   including  revenues  of
approximately  $381,000 and  $849,000,  respectively.  Included in (loss) income
from discontinued operations for the six months ended June 30, 2005 and 2004 are
results of the  property's  operations  of  approximately  $144,000 and $75,000,
respectively,  including  revenues of  approximately  $1,233,000  and $1,641,000
respectively.

Note E - Casualty Events

During  the six  months  ended  June  30,  2005  there  was a  casualty  gain of
approximately $29,000 recorded for Stratford Place Apartments related to damages
to the property  caused by a fire on January 12, 2005.  This gain was the result
of the receipt of insurance proceeds of approximately $50,000,  partially offset
by the write off of undepreciated  fixed assets of approximately  $21,000 and is
included in (loss) income from discontinued operations.

On February 1, 2005, a flood occurred at Stratford Place Apartments resulting in
expected property damage of approximately $53,000.  Negotiations concerning this
casualty  are ongoing  with the  insurance  carrier.  The  Partnership  does not
anticipate recording a loss related to this damage.

In 2004, Ashton Ridge Apartments  experienced  damage from hurricane Jeanne. The
Partnership  estimates total damage costs of approximately  $199,000,  which the
Partnership does not expect to be covered by insurance proceeds. The Partnership
recorded a casualty loss of approximately $13,000 related to this event in 2004.
In 2004, the Partnership estimated total cleanup costs from this hurricane would
be  approximately   $20,000.  In  addition,  it  estimated  clean  up  costs  of
approximately  $51,000  related to  hurricane  Frances  in 2004.  During the six
months ended June 30, 2005, the Partnership revised the total estimated clean up
costs  related to  hurricane  damage and reduced the  estimate by  approximately
$56,000. This income is included in operating expenses.

Note F - Contingencies

As previously disclosed,  AIMCO Properties L.P. and NHP Management Company, both
affiliates of the Managing General Partner, are defendants in a lawsuit alleging
that they willfully violated the Fair Labor Standards Act ("FLSA") by failing to
pay  maintenance  workers  overtime  for all hours worked in excess of forty per
week.  The  complaint  attempts to bring a collective  action under the FLSA and
seeks to certify state subclasses in California,  Maryland,  and the District of
Columbia.  Specifically,  the plaintiffs  contend that AIMCO Properties L.P. and
NHP Management  Company failed to compensate  maintenance  workers for time that
they were required to be "on-call".  Additionally,  the complaint  alleges AIMCO
Properties  L.P. and NHP  Management  Company  failed to comply with the FLSA in
compensating maintenance workers for time that they worked in excess of 40 hours
in a week. On June 23, 2005 the Court  conditionally  certified  the  collective
action  on both the  on-call  and  overtime  issues.  The  Court  ruling  allows
plaintiffs  to  provide  notice  of the  collective  action  to  all  non-exempt
maintenance  workers from August 7, 2000 through the  present.  Those  employees
will have the  opportunity to opt-in to the collective  action.  Defendants have
asked the Court to  reconsider  its  ruling or in the  alternative  certify  the
ruling for appeal on that issue. After the notice goes out, defendants will have
the  opportunity to move to decertify the collective  action.  The Court further
denied plaintiffs' Motion for Certification of the state subclass.  Although the
outcome of any litigation is uncertain, AIMCO Properties,  L.P. does not believe
that  the  ultimate   outcome  will  have  a  material  adverse  effect  on  its
consolidated  financial  condition  or results  of  operations.  Similarly,  the
Managing  General Partner does not believe that the ultimate outcome will have a
material adverse effect on the Partnership's consolidated financial condition or
results of operations.

The  Partnership  is unaware  of any other  pending  or  outstanding  litigation
matters  involving  it or its  investment  properties  that are not of a routine
nature arising in the ordinary course of business.

Environmental

Various  Federal,  state and local laws subject  property owners or operators to
liability for management,  and the costs of removal or  remediation,  of certain
hazardous  substances  present on a property.  Such laws often impose  liability
without regard to whether the owner or operator knew of, or was responsible for,
the release or presence of the  hazardous  substances.  The  presence of, or the
failure to manage or remedy properly,  hazardous substances may adversely affect
occupancy at affected  apartment  communities and the ability to sell or finance
affected properties.  In addition to the costs associated with investigation and
remediation  actions  brought by government  agencies,  and  potential  fines or
penalties  imposed by such  agencies in  connection  therewith,  the presence of
hazardous  substances on a property could result in claims by private plaintiffs
for personal injury, disease, disability or other infirmities. Various laws also
impose  liability for the cost of removal,  remediation or disposal of hazardous
substances  through a  licensed  disposal  or  treatment  facility.  Anyone  who
arranges for the disposal or treatment of hazardous  substances  is  potentially
liable  under such laws.  These laws often impose  liability  whether or not the
person arranging for the disposal ever owned or operated the disposal  facility.
In connection with the ownership,  operation and management of its property, the
Partnership could  potentially be liable for environmental  liabilities or costs
associated with its property.

Mold

The Partnership is aware of lawsuits  against owners and managers of multifamily
properties asserting claims of personal injury and property damage caused by the
presence of mold, some of which have resulted in substantial  monetary judgments
or settlements. The Partnership has only limited insurance coverage for property
damage loss claims  arising from the  presence of mold and for  personal  injury
claims related to mold exposure. Affiliates of the Managing General Partner have
implemented a national  policy and  procedures to prevent or eliminate mold from
its properties  and the Managing  General  Partner  believes that these measures
will  minimize  the  effects  that mold could have on  residents.  To date,  the
Partnership  has not  incurred  any material  costs or  liabilities  relating to
claims of mold exposure or to abate mold  conditions.  Because the law regarding
mold is unsettled and subject to change the Managing General Partner can make no
assurance  that  liabilities  resulting from the presence of or exposure to mold
will  not have a  material  adverse  effect  on the  Partnership's  consolidated
financial condition or results of operations.

SEC Investigation

The  Central  Regional  Office of the  United  States  Securities  and  Exchange
Commission (the "SEC")  continues its formal  investigation  relating to certain
matters.  Although  the staff of the SEC is not limited in the areas that it may
investigate,  AIMCO believes the areas of  investigation  have included  AIMCO's
miscalculated   monthly  net  rental  income  figures  in  third  quarter  2003,
forecasted  guidance,  accounts  payable,  rent  concessions,   vendor  rebates,
capitalization of payroll and certain other costs, tax credit transactions,  and
tender offers for limited  partnership  interests.  AIMCO is cooperating  fully.
AIMCO is not able to predict when the investigation will be resolved. AIMCO does
not believe that the ultimate outcome will have a material adverse effect on its
consolidated  financial  condition  or results  of  operations.  Similarly,  the
Managing  General Partner does not believe that the ultimate outcome will have a
material adverse effect on the Partnership's consolidated financial condition or
results of operations.







ITEM 2.     Management's Discussion and Analysis or Plan of Operation

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;  real estate risks, including variations of real estate values and
the general  economic  climate in local markets and  competition  for tenants in
such markets;  litigation,  including  costs  associated  with  prosecuting  and
defending  claims  and  any  adverse   outcomes,   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.  The
following  table sets forth the average  occupancy  of the  property for the six
months ended June 30, 2005 and 2004:



                                                   Average Occupancy
                                                    2005       2004
      Ashton Ridge Apartments
                                                         
        Jacksonville, Florida                       96%        90%


The Property  attributes the increase in occupancy at Ashton Ridge Apartments to
improved market conditions.

The  Partnership's  financial  results depend upon a number of factors including
the ability to attract and  maintain  tenants at the  investment  property,  the
interest rate on the mortgage  loan,  costs  incurred to operate the  investment
property,  general  economic  conditions  and  weather.  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,  the Managing  General Partner may use
rental  concessions  and  rental  rate  reductions  to offset  softening  market
conditions, accordingly, there is no guarantee that the Managing General Partner
will be able to  sustain  such a plan.  Further,  a number of  factors  that are
outside the control of the  Partnership  such as the local economic  climate and
weather can adversely or positively affect the Partnership's financial results.

Results of Operations

The  Partnership's  net income for the three and six months  ended June 30, 2005
was  approximately  $21,909,000  and  $22,067,000  compared  to  net  income  of
approximately  $59,000 and  $147,000 for the three and six months ended June 30,
2004.  The increase in net income is due to the gain on sale of Stratford  Place
Apartments  during the six months  ended June 30, 2005 and an increase in income
from  continuing  operations,  partially  offset by a  decrease  in income  from
discontinued operations.

On May 17, 2005, the  Partnership  sold Stratford Place  Apartments,  located in
Gaithersburg,  Maryland,  to a third party for  $29,000,000.  After  payment and
accrual of closing  costs,  the net sales proceeds  received by the  Partnership
were approximately  $28,052,000.  The Partnership used a portion of the proceeds
to repay the mortgage encumbering the property of approximately $8,008,000.  The
sale  resulted  in a gain  on  sale  of  investment  property  of  approximately
$22,064,000  during  the six  months  ended  June 30,  2005.  In  addition,  the
Partnership  recorded a loss on early  extinguishment  of debt of  approximately
$283,000  as a  result  of  prepayment  penalties  paid  and  the  write  off of
unamortized  loan costs,  which is included in (loss)  income from  discontinued
operations. Included in (loss) income from discontinued operations for the three
months ended June 30, 2005 and 2004 are results of the property's  operations of
approximately   $70,000  and  $98,000,   respectively,   including  revenues  of
approximately  $381,000 and  $849,000,  respectively.  Included in (loss) income
from discontinued operations for the six months ended June 30, 2005 and 2004 are
results of the  property's  operations  of  approximately  $144,000 and $75,000,
respectively,  including  revenues of  approximately  $1,233,000 and $1,641,000,
respectively.

The Partnership  recognized  income from continuing  operations of approximately
$58,000 and $142,000  for the three and six months ended June 30, 2005  compared
to (loss)  income from  continuing  operations  of  approximately  $(39,000) and
$72,000  for the  corresponding  periods in 2004.  The  increase  in income from
continuing  operations  for the three  months  ended June 30,  2005 is due to an
increase in total  revenues  and a decrease in total  expenses.  The increase in
income for the six months  ended June 30,  2005 is due to an  increase  in total
revenues partially offset by an increase in total expenses.

Total revenues increased for the three and six months ended June 30, 2005 due to
an increase in rental income.  The increase in total revenues for the six months
ended June 30, 2005 was partially  offset by a decrease in other  income.  Other
income remained relatively constant for three months ended June 30, 2005. Rental
income  increased for both periods due to an increase in occupancy,  an increase
in the average  rental  rates and a decrease in bad debt expense at Ashton Ridge
Apartments.  Other  income  decreased  for the six months  ended  June 30,  2005
primarily due to a decrease in lease  cancellation  fees partially  offset by an
increase  in interest  income due to higher  average  cash  balances in interest
bearing accounts.

Total expenses increased for the six months ended June 30, 2005 due to increases
in operating expenses and general and  administrative  expenses partially offset
by a decrease in depreciation  expense.  Total expenses  decreased for the three
months  ended June 30,  2005 due to  decreases  in  operating  and  depreciation
expenses,  partially  offset  by  an  increase  in  general  and  administrative
expenses.  Operating  expenses  increased for the six months ended June 30, 2005
due to an  increase  in  property  expense  partially  offset by a  decrease  in
maintenance  expense.  Operating  expenses  decreased for the three months ended
June 30, 2005  primarily  due to a decrease  in  maintenance  expense.  Property
expense  increased  for the six months  ended June 30, 2005 due to  increases in
courtesy  patrol  costs,  commissions  and referral fees and utilities at Ashton
Ridge  Apartments.  Maintenance  expense  decreased for the three and six months
ended June 30, 2005 primarily due to a reduction of the estimated  cleanup costs
related to Hurricane  Jeanne at Ashton Ridge  Apartments  (as  discussed  below)
partially  offset by an  increase  in contract  services.  Depreciation  expense
decreased  for the  three  and six  months  ended  June 30,  2005 due to  assets
becoming fully depreciated in 2004 at Ashton Ridge Apartments.

The increase in general and administrative expenses for the three and six months
ended June 30,  2005 was  primarily  due to an increase in the costs of services
included in the management  reimbursements  to the Managing  General  Partner as
allowed  under  the  Partnership   Agreement.   Also  included  in  general  and
administrative  expenses  are costs  associated  with the  quarterly  and annual
communications  with  investors  and  regulatory  agencies  and the annual audit
required by the Partnership Agreement.

During  the six  months  ended  June  30,  2005  there  was a  casualty  gain of
approximately $29,000 recorded for Stratford Place Apartments related to damages
to the property  caused by a fire on January 12, 2005.  This gain was the result
of the receipt of insurance proceeds of approximately $50,000,  partially offset
by the write off of undepreciated  fixed assets of approximately  $21,000 and is
included in (loss) income from discontinued operations.

On February 1, 2005, a flood occurred at Stratford Place Apartments resulting in
expected property damage of approximately $53,000.  Negotiations concerning this
casualty  are ongoing  with the  insurance  carrier.  The  Partnership  does not
anticipate recording a loss related to this damage.

In 2004, Ashton Ridge Apartments  experienced  damage from hurricane Jeanne. The
Partnership  estimates total damage costs of approximately  $199,000,  which the
Partnership does not expect to be covered by insurance proceeds. The Partnership
recorded a casualty loss of approximately $13,000 related to this event in 2004.
In 2004, the Partnership estimated total cleanup costs from this hurricane would
be  approximately   $20,000.  In  addition,  it  estimated  clean  up  costs  of
approximately  $51,000  related to  hurricane  Frances  in 2004.  During the six
months ended June 30, 2005, the Partnership revised the total estimated clean up
costs  related to  hurricane  damage and reduced the  estimate by  approximately
$56,000. This income is included in operating expenses.

Liquidity and Capital Resources

At June 30, 2005, the Partnership had cash and cash equivalents of approximately
$2,576,000 compared to approximately  $1,420,000 at June 30, 2004. Cash and cash
equivalents  increased  approximately  $2,268,000 since December 31, 2004 due to
approximately   $889,000  of  cash   provided  by   operating   activities   and
approximately  $27,514,000 of cash provided by investing  activities,  partially
offset by approximately  $26,135,000 of cash used in financing activities.  Cash
provided  by  investing  activities  consisted  of  proceeds  from  the  sale of
Stratford  Place  Apartments,  receipts from escrow  accounts  maintained by the
mortgage   lenders  and  insurance   proceeds,   partially  offset  by  property
improvements and replacements.  Cash used in financing  activities  consisted of
principal   payments  made  on  the  mortgages   encumbering  the  Partnership's
investment properties, repayment of the mortgage note payable as a result of the
sale of Stratford Place Apartments,  prepayment penalties paid, distributions to
partners  and  repayments  of  advances  from  affiliates,  partially  offset by
advances from affiliates.  The Partnership  invests its working capital reserves
in interest bearing accounts.

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.  For
example,  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.  Capital  improvements  planned for the
Partnership's property are detailed below.

Ashton Ridge Apartments

During  the  six  months  ended  June  30,  2005,  the   Partnership   completed
approximately  $466,000  of  capital  improvements  at Ashton  Ridge  Apartments
consisting  primarily of floor covering  replacements,  roof  replacement,  wood
replacement,  interior  and exterior  painting,  major  landscaping,  structural
improvements and  reconstruction  of damages to the property caused by Hurricane
Jeanne. These improvements were funded from operating cash flow. The Partnership
regularly  evaluates the capital  improvement  needs of the property.  While the
Partnership  has  no  material   commitments  for  property   improvements   and
replacements,  certain routine capital expenditures are anticipated during 2005.
Such capital  expenditures will depend on the physical condition of the property
as well as anticipated cash flow generated by the property.

Stratford Place Apartments

During  the  six  months  ended  June  30,  2005,  the   Partnership   completed
approximately  $339,000 of capital  improvements at Stratford  Place  Apartments
consisting  primarily of floor covering,  window and appliance  replacements and
reconstruction  of damages to the  property  caused by a fire at the property in
January 2005 (see  discussion in "Results of  Operations").  These  improvements
were  funded  from  insurance  proceeds,  operating  cash  flow and  replacement
reserves. The property was sold to a third party on May 17, 2005.

Capital  expenditures will be incurred only if cash is available from operations
or from  Partnership  reserves.  To the extent  that  capital  improvements  are
completed,  the Partnership's  distributable cash flow, if any, may be adversely
affected in the short term.

The  Partnership's  assets are thought to be sufficient for any near-term  needs
(exclusive  of  capital   improvements)   of  the   Partnership.   The  mortgage
indebtedness encumbering Ashton Ridge Apartments of approximately $5,371,000 has
a maturity  date of January 2021 at which time the loan is scheduled to be fully
amortized.

The Partnership  distributed  the following  amounts during the six months ended
June 30, 2005 and 2004 (in thousands except per unit data):



                                          Per                               Per

                        Ended         Partnership         Ended         Partnership
                    June 30, 2005         Unit        June 30, 2004         Unit

                                                                
Sale (1)               $ 17,679         $ 763.86           $ --             $ --


(1) From the sale proceeds of Stratford Place Apartments in May 2005.


Future  cash  distributions  will  depend  on the level of cash  generated  from
operations,  availability  of cash  reserves  and the  timing of debt  maturity,
refinancing   and/or  property  sale.  The  Partnership's   cash  available  for
distribution is reviewed on a monthly basis. There can be no assurance, however,
that the  Partnership  will generate  sufficient  funds from  operations,  after
required  capital  expenditures,  to permit  any  further  distributions  to its
partners during 2005 or subsequent periods.

Other

In addition to its indirect  ownership of the general  partner  interests in the
Partnership,  AIMCO and its affiliates owned 10,984.25 limited partnership units
(the "Units") in the Partnership representing 47.47% of the outstanding Units at
June 30, 2005. 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 in exchange for cash or a combination of cash and
units in AIMCO  Properties,  L.P.,  the  operating  partnership  of AIMCO either
through  private  purchases  or  tender  offers.  Pursuant  to  the  Partnership
Agreement,  unitholders  holding a majority  of the Units are  entitled  to take
action  with  respect to a variety of matters  that would  include,  but are not
limited to, voting on certain amendments to the Partnership Agreement and voting
to remove the Managing General  Partner.  As a result of its ownership of 47.47%
of the  outstanding  units,  AIMCO  and  its  affiliates  are in a  position  to
influence all 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 consolidated 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  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, but are not limited
to,  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 impairment of the Partnership's
assets.

Revenue Recognition

The Partnership generally leases apartment units for twelve-month terms or less.
The Partnership will offer rental concessions during particularly slow months or
in response  to heavy  competition  from other  similar  complexes  in the area.
Rental income attributable to leases, net of any concessions, is recognized on a
straight-line  basis over the term of the lease.  The Partnership  evaluates all
accounts  receivable  from  residents and  establishes  an allowance,  after the
application of security deposits,  for accounts greater than 30 days past due on
current tenants and all receivables due from former tenants.

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.





                           PART II - OTHER INFORMATION


ITEM 1.     LEGAL PROCEEDINGS

As previously disclosed,  AIMCO Properties L.P. and NHP Management Company, both
affiliates of the Managing General Partner, are defendants in a lawsuit alleging
that they willfully violated the Fair Labor Standards Act ("FLSA") by failing to
pay  maintenance  workers  overtime  for all hours worked in excess of forty per
week.  The  complaint  attempts to bring a collective  action under the FLSA and
seeks to certify state subclasses in California,  Maryland,  and the District of
Columbia.  Specifically,  the plaintiffs  contend that AIMCO Properties L.P. and
NHP Management  Company failed to compensate  maintenance  workers for time that
they were required to be "on-call".  Additionally,  the complaint  alleges AIMCO
Properties  L.P. and NHP  Management  Company  failed to comply with the FLSA in
compensating maintenance workers for time that they worked in excess of 40 hours
in a week. On June 23, 2005 the Court  conditionally  certified  the  collective
action  on both the  on-call  and  overtime  issues.  The  Court  ruling  allows
plaintiffs  to  provide  notice  of the  collective  action  to  all  non-exempt
maintenance  workers from August 7, 2000 through the  present.  Those  employees
will have the  opportunity to opt-in to the collective  action.  Defendants have
asked the Court to  reconsider  its  ruling or in the  alternative  certify  the
ruling for appeal on that issue. After the notice goes out, defendants will have
the  opportunity to move to decertify the collective  action.  The Court further
denied plaintiffs' Motion for Certification of the state subclass.  Although the
outcome of any litigation is uncertain, AIMCO Properties,  L.P. does not believe
that  the  ultimate   outcome  will  have  a  material  adverse  effect  on  its
consolidated  financial  condition  or results  of  operations.  Similarly,  the
Managing  General Partner does not believe that the ultimate outcome will have a
material adverse effect on the Partnership's consolidated financial condition or
results of operations.

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.

            during the period in which this report is being prepared;

      (b)   Evaluated  the   effectiveness   of  the  small  business   issuer's
            disclosure  controls and procedures and presented in this report our
            conclusions about the  effectiveness of the disclosure  controls and

      (c)   Disclosed in this report any change in the small  business  issuer's
            internal  control over financial  reporting that occurred during the
            small  business  issuer's  most  recent  fiscal  quarter  (the small
            business  issuer's  fourth  fiscal  quarter in the case of an annual
            report) that has  materially  affected,  or is reasonably  likely to
            materially affect, the small business issuer's internal control over
            financial reporting; and

5.    The  small  business  issuer's  other  certifying  officer(s)  and I  have
      disclosed,  based on our most recent  evaluation of internal  control over
      financial reporting, to the small business issuer's auditors and the audit
      committee of the small  business  issuer's  board of directors (or persons
      performing the equivalent functions):

      (a)   All significant  deficiencies and material  weaknesses in the design
            or operation of internal control over financial  reporting which are
            reasonably  likely to adversely  affect the small business  issuer's
            ability  to  record,   process,   summarize  and  report   financial
            information; and


      (b)   Any fraud,  whether or not  material,  that  involves  management or
            other  employees who have a significant  role in the small  business
            issuer's internal control over financial reporting.
