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  nine  months  ended  September  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

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 nine months ended  September  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 nine  months  ended  September  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  $62,000 and
$137,000 for the three and nine months ended  September 30, 2004,  respectively,
including revenues of approximately $859,000 and $2,500,000, 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 (i) certain  payments to
affiliates for services and (ii)  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  $170,000 and
$219,000 during the nine months ended September 30, 2005 and 2004, respectively,
which is included in  operating  expenses  and income  (loss) from  discontinued
operations.

Affiliates  of  the  Managing   General  Partner  charged  the  Partnership  for
reimbursement of accountable  administrative expenses amounting to approximately
$175,000  and  $89,000 for the nine months  ended  September  30, 2005 and 2004,
respectively  which is  included  in general  and  administrative  expenses  and
investment property. The portion of these reimbursements  included in investment
property are fees related to  construction  management  services  provided by an
affiliate of the Managing  General Partner of  approximately  $89,000 and $4,000
for the nine  months  ended  September  30,  2005 and  2004,  respectively.  The
construction  management  service fees are  calculated  based on a percentage of
certain additions to investment property.

During the nine  months  ended  September  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% (8.75%
at  September  30,  2005) and was less than  $1,000  for the nine  months  ended
September 30, 2005.  The advance and associated  accrued  interest was repaid by
the Partnership during the same period.

The  Partnership  insures 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,   general
liability 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,  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 nine months ended  September 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 income  (loss) from  discontinued
operations. Included in income (loss) from discontinued operations for the three
months  ended  September  30,  2005  and  2004  are  results  of the  property's
operations  of  approximately  $105,000  and  $62,000,  respectively,  including
revenues of  approximately  $105,000  and  $859,000,  respectively.  Included in
income (loss) from  discontinued  operations for the nine months ended September
30,  2005 and 2004 are results of the  property's  operations  of  approximately
($34,000)  and  $137,000,  respectively,  including  revenues  of  approximately
$1,338,000 and $2,500,000 respectively.

Note E - Casualty Events

During the nine months  ended  September  30, 2005 there was a casualty  gain of
approximately  $100,000  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 $121,000, partially
offset by the write off of undepreciated  fixed assets of approximately  $21,000
and is included in income (loss) from discontinued operations.

During the nine months  ended  September  30, 2005 there was a casualty  gain of
approximately $34,000 recorded for Stratford Place Apartments related to damages
to the property  caused by a flood on February 1, 2005. This gain was the result
of the receipt of insurance proceeds of approximately $34,000 and is included in
income (loss) from discontinued operations.

In 2004, Ashton Ridge Apartments  experienced  damage from hurricane Jeanne. The
Partnership  estimated total damage costs of approximately  $199,000,  which the
Partnership did not expect to be covered by insurance proceeds.  The Partnership
recorded a casualty loss of  approximately  $12,000 related to this event in the
nine months ended September 30, 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  nine  months  ended  September  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. During the nine months ended September 30, 2005,
the  Partnership  recorded a casualty loss of  approximately  $10,000 related to
these events. This loss was the result of the write off of undepreciated  assets
of approximately $10,000.

Note F - Contingencies

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,  filed in the United States  District  Court for the District of
Columbia,  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. In June 2005 the Court conditionally  certified the collective action
on both the on-call and overtime issues,  which allows the 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,  and AIMCO Properties,  L.P. and NHP Management
Company will have the  opportunity to move to decertify the  collective  action.
Because the court denied  plaintiffs'  motion to certify  state  subclasses,  on
September  26,  2005,  the  plaintiffs  filed  a  class  action  with  the  same
allegations in the Superior Court of California (Contra Costa County).  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 property 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 nine
months ended September 30, 2005 and 2004:

                                                   Average Occupancy
                                                    2005       2004
      Ashton Ridge Apartments
        Jacksonville, Florida                       95%        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 nine months ended September 30,
2005 was approximately $161,000 and $22,228,000,  respectively,  compared to net
(loss)  income of  approximately  ($49,000)  and  $98,000 for the three and nine
months ended  September 30, 2004,  respectively.  The increase in net income for
the three  months  ended  September  30, 2005 is due to increases in income from
continuing  operations and discontinued  operations.  The increase in net income
for the  nine  months  ended  September  30,  2005 is due to the gain on sale of
Stratford Place  Apartments,  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 nine months ended  September 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 income  (loss) from  discontinued
operations. Included in income (loss) from discontinued operations for the three
months  ended  September  30,  2005  and  2004  are  results  of the  property's
operations  of  approximately  $105,000  and  $62,000,  respectively,  including
revenues of  approximately  $105,000  and  $859,000,  respectively.  Included in
income (loss) from  discontinued  operations for the nine months ended September
30,  2005 and 2004 are results of the  property's  operations  of  approximately
($34,000)  and  $137,000,  respectively,  including  revenues  of  approximately
$1,338,000 and $2,500,000 respectively.

As a result of the sale of Stratford  Place  Apartments  and in accordance  with
Statement of Financial Accounting Standard ("SFAS") No. 144, "Accounting for the
Impairment  or Disposal of Long-Lived  Assets",  the  accompanying  consolidated
statements of operations for the three and nine months ended  September 30, 2004
have been restated as of January 1, 2004 to reflect the  operations of Stratford
Place Apartments as income from discontinued operations.  The increase in income
from  discontinued  operations for the three months ended  September 30, 2004 is
due to casualty  gains  recorded  due to  insurance  proceeds  received  for two
casualties  that  occurred at Stratford  Place  Apartments  prior to its sale as
discussed  below.  The decrease in income from  discontinued  operations for the
nine months  ended  September  30, 2005 is due to primarily to the loss on early
extinguishment of debt recorded as a result of the sale as discussed above.

The Partnership  recognized  income from continuing  operations of approximately
$56,000 and  $198,000 for the three and nine months  ended  September  30, 2005,
respectively,  compared  to loss from  continuing  operations  of  approximately
$111,000  and $39,000 for the  corresponding  periods in 2004.  The  increase in
income from continuing  operations for the three and nine months ended September
30, 2005 is due to increases in total revenues and decreases in total expenses.

Total revenues  increased for the three and nine months ended September 30, 2005
due to increases in rental and other income.  Rental  income  increased for both
periods due to an increase in occupancy,  an increase in the average rental rate
and a decrease in bad debt  expense at Ashton  Ridge  Apartments.  Other  income
increased for the three and nine months ended  September 30, 2005  primarily due
to an increase in resident  utility  reimbursements  and an increase in interest
income  due to  higher  average  cash  balances  in  interest  bearing  accounts
partially offset by a decrease in lease cancellation fees.

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

During the nine months  ended  September  30, 2005 there was a casualty  gain of
approximately  $100,000  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 $121,000, partially
offset by the write off of undepreciated  fixed assets of approximately  $21,000
and is included in income (loss) from discontinued operations.

During the nine months  ended  September  30, 2005 there was a casualty  gain of
approximately $34,000 recorded for Stratford Place Apartments related to damages
to the property  caused by a flood on February 1, 2005. This gain was the result
of the receipt of insurance proceeds of approximately $34,000 and is included in
income (loss) from discontinued operations.

In 2004, Ashton Ridge Apartments  experienced  damage from hurricane Jeanne. The
Partnership  estimated total damage costs of approximately  $199,000,  which the
Partnership did not expect to be covered by insurance proceeds.  The Partnership
recorded a casualty loss of  approximately  $12,000 related to this event in the
nine months ended September 30, 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  nine  months  ended  September  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. During the nine months ended September 30, 2005,
the  Partnership  recorded a casualty loss of  approximately  $10,000 related to
these events. This loss was the result of the write off of undepreciated  assets
of approximately $10,000.

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

Liquidity and Capital Resources

At  September  30,  2005,  the  Partnership  had cash and  cash  equivalents  of
approximately  $1,434,000 compared to approximately  $1,481,000 at September 30,
2004.  Cash  and  cash  equivalents  increased  approximately  $1,126,000  since
December 31, 2004 due to approximately  $1,231,000 of cash provided by operating
activities  and   approximately   $27,443,000  of  cash  provided  by  investing
activities,  partially  offset  by  approximately  $27,548,000  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.

During the nine months ended  September  30,  2005,  the  Partnership  completed
approximately  $614,000  of  capital  improvements  at Ashton  Ridge  Apartments
consisting  primarily of floor covering and air conditioning unit  replacements,
roof  replacement,  wood  replacement,  interior  and exterior  painting,  major
landscaping,  fencing,  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 nine months ended  September  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 and a flood in  February  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 $5,308,000 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 nine months ended
September 30, 2005 and 2004 (in thousands except per unit data):



                                         Per                                Per

                      Ended          Partnership         Ended          Partnership
               September 30, 2005       Unit      September 30, 2004        Unit

                                                             
Sale (1)            $ 19,029          $ 822.20           $ --               $ --


(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
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
September  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
asset.

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

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,  filed in the United States  District  Court for the District of
Columbia,  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. In June 2005 the Court conditionally  certified the collective action
on both the on-call and overtime issues,  which allows the 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,  and AIMCO Properties,  L.P. and NHP Management
Company will have the  opportunity to move to decertify the  collective  action.
Because the court denied  plaintiffs'  motion to certify  state  subclasses,  on
September  26,  2005,  the  plaintiffs  filed  a  class  action  with  the  same
allegations in the Superior Court of California (Contra Costa County).  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.

4.    The  small  business  issuer's  other  certifying  officer(s)  and  I  are

      procedures (as defined in Exchange Act Rules  13a-15(e) and 15d-15(e)) for
      the small business issuer and have:

      (a)   Designed such  disclosure  controls and  procedures,  or caused such
            disclosure   controls  and  procedures  to  be  designed  under  our

            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

      committee of the small  business  issuer's  board of directors (or persons

            or operation of internal control over financial  reporting which are

            ability  to  record,   process,   summarize  and  report   financial

I, Stephen B. Waters, certify that:


1.    I have reviewed this  quarterly  report on Form 10-QSB of Winthrop  Growth
      Investors I Limited Partnership;

2.    Based on my knowledge,  this report does not contain any untrue  statement
      of a material fact or omit to state a material fact  necessary to make the
      statements made, in light of the circumstances under which such statements
      were made,  not  misleading  with  respect  to the period  covered by this
      report;

3.    Based on my  knowledge,  the  financial  statements,  and other  financial
      information  included  in this  report,  fairly  present  in all  material
      respects the financial condition,  results of operations and cash flows of
      the small  business  issuer as of, and for, the periods  presented in this
      report;

4.    The  small  business  issuer's  other  certifying  officer(s)  and  I  are
      responsible  for  establishing  and  maintaining  disclosure  controls and
      procedures (as defined in Exchange Act Rules  13a-15(e) and 15d-15(e)) for
      the small business issuer and have:

      (a)   Designed such  disclosure  controls and  procedures,  or caused such
            disclosure   controls  and  procedures  to  be  designed  under  our
            supervision,  to ensure that  material  information  relating to the
            small business issuer, including its consolidated  subsidiaries,  is
            made  known to us by  others  within  those  entities,  particularly
            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
            procedures, as of the end of the period covered by this report based
            on such evaluation; 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.
