     subscriptions    of   1,500   Limited   Partnership    Units
     ($1,500,000)  were  accepted.   On  January  31,  1997,  the
     offering  terminated when the maximum subscription limit  of
     24,000 Limited Partnership Units ($24,000,000) was reached.

     Under  the  terms of the Limited Partnership Agreement,  the
     Limited  Partners and General Partners contributed funds  of
     $24,000,000  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 1% to the General Partners  until  the
     Limited  Partners  receive an amount  equal  to:  (a)  their
     Adjusted  Capital Contribution plus (b) an amount  equal  to
     10%  of  their  Adjusted  Capital  Contribution  per  annum,
     cumulative  but not compounded, to the extent not previously
     distributed  from Net Cash Flow; (ii) any remaining  balance
     will  be distributed 90% to the Limited Partners and 10%  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 in  the
     same  ratio  as  the  last  dollar  of  Net  Cash  Flow   is
     distributed.   Net losses from operations will be  allocated
     99% to the Limited Partners and 1% 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 10% of their Adjusted Capital Contributions
     per  annum, cumulative but not compounded, to the extent not
     previously  allocated;  (iii)  third,  the  balance  of  any
     remaining  gain  will then be allocated 90% to  the  Limited
     Partners  and 10% 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)  Short-Term Note Receivable -

     On  August 2, 2000, the Partnership received a Contract  for
     Deed  from an affiliate of the buyer of the Media Play store
     in  Apple Valley, Minnesota.  The Note bore interest  at  9%
     and was secured by the land, building and equipment.  As  of
     December  31,  2000, the Partnership's share of  outstanding
     principal  due  on the Note was $675,920.   On  January  16,
     2001, the Partnership received the outstanding principal and
     accrued interest on the Note.

(4)  Investments in Real Estate -

     On  August  2,  2000, the Media Play store was  sold  to  an
     unrelated  third party for $2,500,000.  The  sale  agreement
     required  $500,000  in  cash and a $2,000,000  Contract  for
     Deed,  which bore interest at 9%.  On January 16, 2001,  the
     Partnership received its share of the outstanding  principal
     and  accrued interest on the Note.  The Partnership's  share
     of  the net sale proceeds was $820,651, which resulted in  a
     net  gain  of $129,813.  At the time of sale, the  cost  and
     related accumulated depreciation was $833,860 and $143,022.

     Through June 30, 2001, the Partnership sold its interest  in
     the  Champps  Americana  restaurant in  Columbus,  Ohio,  in
     eleven  separate transactions, to unrelated  third  parties.
     The   Partnership  received  total  net  sale  proceeds   of
     $2,295,174, which resulted in a total net gain of  $631,607.
     The  total cost and related accumulated depreciation of  the
     interests  sold  was $1,808,880 and $145,313,  respectively.
     For  the  six months ended June 30, 2001, the net  gain  was
     $289,679.

     Through June 30, 2001, the Partnership sold 16.1171% of  the
     Champps  Americana  restaurant in Schaumburg,  Illinois,  in
     five separate transactions, to unrelated third parties.  The
     Partnership  received total net sale proceeds  of  $930,207,
     which  resulted in a total net gain of $254,776.  The  total
     cost  and  related accumulated depreciation of the interests
     sold  was $733,218 and $57,787, respectively.  For  the  six
     months ended June 30, 2001, the net gain was $160,941.

     Subsequent  to  June  30,  2001,  the  Partnership  sold  an
     additional  5.8928% of the Champps Americana  restaurant  in
     Schaumburg,  Illinois,  in  two  separate  transactions,  to
     unrelated third parties.  The Partnership received net  sale
     proceeds of approximately $335,000 which resulted in  a  net
     gain of approximately $91,000.

     During  the  first  six  months  of  2000,  the  Partnership
     distributed $55,577 of the net sale proceeds to the  Limited
     and  General  Partners  as part of their  regular  quarterly
     distributions which represented a return of capital of $2.34
     per  Limited  Partnership  Unit.   The  remaining  net  sale
     proceeds will either be reinvested in additional property or
     distributed to the Partners in the future.

     On March 8, 2000, the Partnership purchased a parcel of land
     in  Fort Wayne, Indiana for $549,000.  The land is leased to
     Tumbleweed,  Inc.  (TWI)  under a  Lease  Agreement  with  a
     primary  term  of  15  years and annual rental  payments  of
     $48,038.  Simultaneously with the purchase of the land,  the
     Partnership  entered into a Development Financing  Agreement
     under  which the Partnership advanced funds to TWI  for  the
     construction  of  a  Tumbleweed  restaurant  on  the   site.
     Initially, the Partnership charged interest on the  advances
     at  a  rate of 8.75%.  Effective July 5, 2000, the  interest
     rate  was increased to 9.875%.  On September 11, 2000, after
     the  development  was  completed, the  Lease  Agreement  was
     amended  to  require  annual rental  payments  of  $132,621.
     Total  acquisition costs, including the cost  of  the  land,
     were $1,334,315.

     On  March  30, 2001, the Partnership purchased a  Children's
     World  daycare center in Mundelein, Illinois for $1,618,824.
     The  property  is  leased to ARAMARK Educational  Resources,
     Inc. under a Lease Agreement with a primary term of 15 years
     and annual rental payments of $153,710.

     On  March  8, 2001, the Partnership purchased a 25% interest
     in a parcel of land in Austin, Texas for $283,000.  The land
     is leased to Kona Restaurant Group, Inc. (KRG) under a Lease
     Agreement with a primary term of 17 years and annual  rental
     payments  of  $29,715.  Simultaneously with the purchase  of
     the   land,  the  Partnership  entered  into  a  Development
     Financing Agreement under which the Partnership will advance
     funds  to  KRG  for  the construction of a  Johnny  Carino's
     restaurant  on  the  site.   Through  June  30,  2001,   the
     Partnership  had  advanced $166,957 for the construction  of
     the property and was charging interest on the advances at  a
     rate  of  10.5%.   The  Partnership's  share  of  the  total
     purchase  price,  including the cost of the  land,  will  be
     approximately $573,000.  After the construction is complete,
     the Lease Agreement will be amended to require annual rental
     payments  of approximately $60,000.  The remaining interests
     in  the  property  are owned by AEI Real  Estate  Fund  85-A
     Limited  Partnership, AEI Net Lease Income & Growth Fund  XX
     Limited  Partnership, and AEI Income & Growth Fund  23  LLC,
     affiliates of the Partnership.

(5)  Payable to AEI Fund Management, Inc. -

     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.


ITEM 2.MANAGEMENT'S DISCUSSION AND ANALYSIS

Results of Operations

        For  the  six  months ended June 30, 2001 and  2000,  the
Partnership  recognized rental income of $946,807  and  $854,427,
respectively.   During the same periods, the  Partnership  earned
investment income of $40,843 and $55,599, respectively.  In 2001,
rental  income increased as a result of additional rent  received
from  three  property acquisitions in 2000  and  2001,  and  rent
increases  on five properties.  These increases in rental  income
were  partially offset by a decrease in rental income due to  the
property sales discussed below.

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

        During  the six months ended June 30, 2001 and 2000,  the
Partnership   paid   Partnership   administration   expenses   to
affiliated parties of $137,724 and $131,233, respectively.  These
administration  expenses  include  costs  associated   with   the
management of the properties, processing distributions, reporting
requirements and correspondence to the Limited Partners.   During
the   same   periods,   the  Partnership   incurred   Partnership
administration  and property management expenses  from  unrelated
parties  of  $13,461 and $46,491, respectively.   These  expenses
represent  direct payments to third parties for legal and  filing
fees,  direct administrative costs, outside audit and  accounting
costs,  taxes, insurance and other property costs.  The  decrease
in  these expenses in 2001, when compared to 2000, is mainly  the
result  of  expenses incurred in 2000 related to the  Media  Play
store.

        As  of  June 30, 2001, the Partnership's annualized  cash
distribution  rate  was  6.75%, based  on  the  Adjusted  Capital
Contribution.   Distributions of Net Cash  Flow  to  the  General
Partners were subordinated to the Limited Partners as required in
the Partnership Agreement.  As a result, 99% of distributions and
income  were allocated to Limited Partners and 1% to the  General
Partners.

        Inflation  has  had  a  minimal  effect  on  income  from
operations.   The  Leases contain cost of living increases  which
will result in an increase in rental income over the term of  the
Leases.   Inflation also may cause the Partnership's real  estate
to  appreciate in value.  However, inflation and changing  prices
may  also have an adverse impact on the operating margins of  the
properties' tenants which could impair their ability to pay  rent
and subsequently reduce the Partnership's Net Cash Flow available
for distributions.

Liquidity and Capital Resources

         During   the  six  months  ended  June  30,  2001,   the
Partnership's cash balances increased $201,152 mainly as a result
of  cash generated from the sale of property, which was partially
offset  by cash used to purchase property.  Net cash provided  by
operating activities increased from $817,842 in 2000 to  $882,250
in  2001  as a result of an increase in income and a decrease  in
Partnership administration expenses in 2001, which were partially
offset  by  net timing differences in the collection of  payments
from the lessees and the payment of expenses.

        The  major components of the Partnership's cash flow from
investing activities are investments in real estate and  proceeds
from  the sale of real estate.  During the six months ended  June
30,  2001, the Partnership generated cash flow from the  sale  of
real  estate  of $1,482,939.  During the six months  ended  June,
2001   and   2000,   the  Partnership  expended  $2,051,958   and
$1,033,144, respectively, to invest in real properties (inclusive
of  acquisition  expenses)  as  the Partnership  reinvested  cash
generated from property sales.

        On  August 2, 2000, the Media Play store was sold  to  an
unrelated   third  party  for  $2,500,000.   The  sale  agreement
required  $500,000  in cash and a $2,000,000 Contract  for  Deed,
which  bore interest at 9%.  On January 16, 2001, the Partnership
received  its  share  of  the outstanding principal  and  accrued
interest  on the Note.  The Partnership's share of the  net  sale
proceeds  was $820,651, which resulted in a net gain of $129,813.
At   the   time   of  sale,  the  cost  and  related  accumulated
depreciation was $833,860 and $143,022.

        Through  June 30, 2001, the Partnership sold its interest
in  the Champps Americana restaurant in Columbus, Ohio, in eleven
separate   transactions,  to  unrelated   third   parties.    The
Partnership received total net sale proceeds of $2,295,174, which
resulted  in  a total net gain of $631,607.  The total  cost  and
related  accumulated  depreciation  of  the  interests  sold  was
$1,808,880 and $145,313, respectively.  For the six months  ended
June 30, 2001, the net gain was $289,679.

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

        Through  June 30, 2001, the Partnership sold 16.1171%  of
the Champps Americana restaurant in Schaumburg, Illinois, in five
separate   transactions,  to  unrelated   third   parties.    The
Partnership  received total net sale proceeds of $930,207,  which
resulted  in  a total net gain of $254,776.  The total  cost  and
related  accumulated  depreciation  of  the  interests  sold  was
$733,218  and  $57,787, respectively.  For the six  months  ended
June 30, 2001, the net gain was $160,941.

        Subsequent  to  June  30, 2001, the Partnership  sold  an
additional  5.8928%  of  the  Champps  Americana  restaurant   in
Schaumburg, Illinois, in two separate transactions, to  unrelated
third  parties.   The Partnership received net sale  proceeds  of
approximately  $335,000  which  resulted  in  a   net   gain   of
approximately $91,000.

        During  the  first  six months of 2000,  the  Partnership
distributed  $55,577 of the net sale proceeds to the Limited  and
General Partners as part of their regular quarterly distributions
which  represented  a  return of capital  of  $2.34  per  Limited
Partnership Unit.  The remaining net sale proceeds will either be
reinvested in additional property or distributed to the  Partners
in the future.

        On  March 8, 2000, the Partnership purchased a parcel  of
land in Fort Wayne, Indiana for $549,000.  The land is leased  to
Tumbleweed,  Inc. (TWI) under a Lease Agreement  with  a  primary
term   of  15  years  and  annual  rental  payments  of  $48,038.
Simultaneously  with  the purchase of the land,  the  Partnership
entered  into a Development Financing Agreement under  which  the
Partnership  advanced  funds to TWI for  the  construction  of  a
Tumbleweed  restaurant on the site.  Initially,  the  Partnership
charged  interest on the advances at a rate of 8.75%.   Effective
July  5,  2000,  the interest rate was increased to  9.875%.   On
September  11,  2000, after the development  was  completed,  the
Lease Agreement was amended to require annual rental payments  of
$132,621.   Total acquisition costs, including the  cost  of  the
land, were $1,334,315.

        On March 30, 2001, the Partnership purchased a Children's
World daycare center in Mundelein, Illinois for $1,618,824.   The
property is leased to ARAMARK Educational Resources, Inc. under a
Lease Agreement with a primary term of 15 years and annual rental
payments of $153,710.

       On March 8, 2001, the Partnership purchased a 25% interest
in  a parcel of land in Austin, Texas for $283,000.  The land  is
leased  to  Kona  Restaurant Group,  Inc.  (KRG)  under  a  Lease
Agreement  with  a  primary term of 17 years  and  annual  rental
payments  of  $29,715.  Simultaneously with the purchase  of  the
land,  the  Partnership  entered  into  a  Development  Financing
Agreement under which the Partnership will advance funds  to  KRG
for the construction of a Johnny Carino's restaurant on the site.
Through June 30, 2001, the Partnership had advanced $166,957  for
the construction of the property and was charging interest on the
advances  at  a rate of 10.5%.  The Partnership's  share  of  the
total  purchase price, including the cost of the  land,  will  be
approximately $573,000.  After the construction is complete,  the
Lease Agreement will be amended to require annual rental payments
of   approximately  $60,000.   The  remaining  interests  in  the
property  are  owned  by  AEI  Real  Estate  Fund  85-A   Limited
Partnership,  AEI  Net  Lease Income &  Growth  Fund  XX  Limited
Partnership,  and AEI Income & Growth Fund 23 LLC, affiliates  of
the Partnership.

       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 in the fourth quarter  of  each
year.   Effective  April 1, 2001, the Partnership's  distribution
rate   was   increased  from  6.5%  to  6.75%.   As   a   result,
distributions were higher in 2001, when compared to 2000.

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

        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.

        During 2000, twelve Limited Partners redeemed a total  of
226.32  Partnership  Units for $186,379 in  accordance  with  the
Partnership  Agreement.   The Partnership  acquired  these  Units
using  Net  Cash Flow from operations.  In prior years,  thirteen
Limited Partners redeemed a total of 451.47 Partnership Units for
$393,500.    The  redemptions  increase  the  remaining   Limited
Partners' ownership interest in the Partnership.

       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.

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 investors;
