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

     AEI   Income   &   Growth   Fund  XXI  Limited   Partnership
     (Partnership)  was  formed to acquire and  lease  commercial
     properties   to   operating  tenants.    The   Partnership's
     operations  are  managed by AEI Fund  Management  XXI,  Inc.
     (AFM),  the  Managing  General Partner of  the  Partnership.
     Robert  P.  Johnson, the President and sole  shareholder  of
     AFM,  serves  as  the  Individual  General  Partner  of  the
     Partnership.  An affiliate of AFM, AEI Fund Management, Inc.
     (AEI),  performs the administrative and operating  functions
     for the Partnership.
     
     The   terms   of  the  Partnership  offering  call   for   a
     subscription  price of $1,000 per Limited Partnership  Unit,
     payable   on  acceptance  of  the  offer.   The  Partnership
     commenced   operations  on  April  14,  1995  when   minimum
     subscriptions    of   1,500   Limited   Partnership    Units
     ($1,500,000)  were  accepted.   On  January  31,  1997,  the
     Partnership    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 the  operation
     of the Partnership, 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 the Partnership's 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  the  Partnership's
     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 the Partnership's 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)  Investments in Real Estate -

     The  Partnership  leases its properties to  various  tenants
     through triple net leases, which are classified as operating
     leases.  Under a triple net lease, the lessee is responsible
     for  all  real estate taxes, insurance, maintenance, repairs
     and  operating expenses of the property.  The initial  Lease
     terms are 20 years except for the Caribou Coffee , which  is
     18  years, and the Media Play retail store discussed  below.
     The  Leases  contain renewal options which  may  extend  the
     Lease term an additional 10 years for the Arby's and Caribou
     Coffee  store,  an additional 15 years for the  Denny's  and
     Champps  Americana restaurants and 25 years for  the  Garden
     Ridge  retail store.  The Leases contain rent clauses  which
     entitle the Partnership to receive additional rent in future
     years based on stated rent increases.  Certain lessees  have
     been granted options to purchase the property.  Depending on
     the  lease,  the  purchase price is either determined  by  a
     formula, or is the greater of the fair market value  of  the
     property  or  the  amount determined by a formula.   In  all
     cases, if the option were to be exercised by the lessee, the
     purchase  price would be greater than the original  cost  of
     the property.
     
     The  Partnership's  properties are all  commercial,  single-
     tenant  buildings.   The cost of the  property  and  related
     accumulated depreciation at June 30, 1998 are as follows:

     On  December  21,  1995, the Partnership purchased  a  34.0%
     interest  in  a  Media Play retail store  in  Apple  Valley,
     Minnesota  for $1,414,060.  The property was leased  to  The
     Musicland Group, Inc. (MGI) under a Lease Agreement  with  a
     primary  term  of  18  years and annual rental  payments  of
     $139,587.

(3)  Investments in Real Estate - (Continued)

     In  December,  1996,  the Partnership  and  MGI  reached  an
     agreement in which MGI would buy out and terminate the Lease
     Agreement  by making a payment of $800,000, which was  equal
     to  approximately two years' rent.  The Partnership's  share
     of  such  payment  was $272,000.  Under the  Agreement,  MGI
     remained in possession of the property and performed all  of
     its  obligations  under  the  net  lease  agreement  through
     January  31, 1997 at which time it vacated the property  and
     made  it  available for re-let to another tenant.   MGI  was
     responsible for all maintenance and management costs of  the
     property  through  January 31, 1997  after  which  date  the
     Partnership  became responsible for its  share  of  expenses
     associated with the property until it is re-let or sold.   A
     specialist in commercial property leasing has been  retained
     to locate a new tenant for the property.
     
     As  of  December  31, 1997, based on an analysis  of  market
     conditions in the area, it was determined the fair value  of
     the   Partnership's   interest  in  the   Media   Play   was
     approximately $748,000.  In the fourth quarter  of  1997,  a
     charge  to operations for real estate impairment of $580,200
     was  recognized,  which is the difference between  the  book
     value  at  December 31, 1997 of $1,328,200 and the estimated
     market  value of $748,000.  The charge was recorded  against
     the cost of the land, building and equipment.
     
     On  March  14, 1997, the Partnership purchased a  parcel  of
     land  in  San  Antonio, Texas for $1,032,299.  The  land  is
     leased  to Champps Americana, Inc. (Champps) under  a  Lease
     Agreement with a primary term of 20 years and annual  rental
     payments  of  $83,451.   Effective September  9,  1997,  the
     annual rent was increased to $128,156.  Simultaneously  with
     the  purchase  of the land, the Partnership entered  into  a
     Development  Financing Agreement under which the Partnership
     advanced funds to Champps for the construction of a  Champps
     Americana   restaurant   on  the   site.    Initially,   the
     Partnership charged interest on the advances at  a  rate  of
     7.0%.   Effective September 9, 1997, the interest  rate  was
     increased  to  10.75%.   On December  23,  1997,  after  the
     development  was completed, the Lease Agreement was  amended
     to  require  annual  rental  payments  of  $296,023.   Total
     acquisition  costs, including the cost  of  the  land,  were
     $2,833,357.
     
     On  March  19,  1997,  the Partnership purchased  a  Denny's
     restaurant  in  Covington, Louisiana  for  $1,304,949.   The
     property  is  leased to Huntington Restaurants  Group,  Inc.
     under a Lease Agreement with a primary term of 20 years  and
     annual rental payments of $141,243.

     Agreement with a primary term of 20 years and annual  rental
     payments of $66,906.  Effective October 17, 1997, the annual
     rent  was  increased to $102,749.  Simultaneously  with  the

     development  was completed, the Lease Agreement was  amended
     to   require  annual  rental  payments  of  $236,479.    The
     Partnership's   share  of  the  total   acquisition   costs,
     including  the  cost  of  the  land,  was  $2,256,462.   The
     remaining  interests in the property are owned  by  AEI  Net
     Lease  Income & Growth Fund XX Limited Partnership  and  Net
     Lease   Income  &  Growth  Fund  84-A  Limited  Partnership,
     affiliates of the Partnership.
     
     On  July 8, 1997, the Partnership purchased a parcel of land
     in  Livonia, Michigan for $1,074,384.  The land is leased to

     Simultaneously   with  the  purchase  of   the   land,   the

     for  the  construction of a Champps Americana restaurant  on
     the  site.   Initially, the Partnership charged interest  on
     the  advances at a rate of 7.0%.  Effective January 3, 1998,
     the interest rate was increased to 10.75%.  On May 19, 1998,

     On July 31, 1997, the Partnership purchased a 93.1% interest
     in  a Caribou Coffee store in Charlotte, North Carolina  for
     $1,310,598.   The  property  is  leased  to  Caribou  Coffee

     of  $1,156,453  which  resulted  in  a  total  net  gain  of
     $276,488.    The   total   cost  and   related   accumulated
     depreciation of the interests sold was $916,080 and $36,115,
     respectively.  For the six months ended June 30,  1998,  the
     net gain was $169,937.
     
     During  the  first  six  months  of  1998,  the  Partnership
     distributed $241,683 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
     $10.04 per Limited Partnership Unit.  The remaining net sale
     proceeds  will either be reinvested in additional properties
     or distributed to the Partners in the future.

ITEM 2.MANAGEMENT'S DISCUSSION AND ANALYSIS

Results of Operations

        For  the  six  months ended June 30, 1998 and  1997,  the
Partnership  recognized rental income of $794,545  and  $416,273,
respectively.   During the same periods, the  Partnership  earned
$126,242  and $299,128, respectively, in investment  income  from
subscriptions  proceeds which were invested in  short-term  money
market accounts, commercial paper and federal agency notes.  This
investment income constituted 14% and 42% respectively, of  total
income   for  the  periods.   The  percentage  of  total   income
represented   by  investment  income  declines  as   subscription
proceeds are invested in properties.

        Musicland Group, Inc. (MGI), the lessee of the Media Play
retail  store  in  Apple Valley, Minnesota experienced  financial
difficulties and was aggressively restructuring its organization.
As  part of the restructuring, the Partnership and MGI reached an
agreement  in  December, 1996 in which  MGI  would  buy  out  and
terminate  the Lease Agreement by making a payment  of  $800,000,
which   is   equal  to  approximately  two  years'   rent.    The
Partnership's  share  of such payment was  $272,000.   Under  the
Agreement,  MGI  remained  in  possession  of  the  property  and
performed  all  of its obligations under the net lease  agreement
through  January 31, 1997 at which time it vacated  the  property
and  made  it  available for re-let to another tenant.   MGI  was
responsible  for  all  maintenance and management  costs  of  the
property   through  January  31,  1997  after  which   date   the
Partnership   became  responsible  for  its  share  of   expenses
associated  with  the property until it is  re-let  or  sold.   A
specialist  in commercial property leasing has been  retained  to
locate a new tenant for the property.

        As  of  December 31, 1997, based on an analysis of market
conditions in the area, it was determined the fair value  of  the
Partnership's  interest  in  the  Media  Play  was  approximately
$748,000.   In the fourth quarter of 1997, a charge to operations
for  real estate impairment of $580,200 was recognized, which  is
the  difference between the book value at December  31,  1997  of
$1,328,200  and  the  estimated market value  of  $748,000.   The
charge  was  recorded against the cost of the land, building  and
equipment.


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

        During  the six months ended June 30, 1998 and 1997,  the
Partnership   paid   Partnership   administration   expenses   to
affiliated parties of $129,131 and $114,273, respectively.  These
administration  expenses  include  initial  start-up  costs   and
expenses  associated  with  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  $63,641 and $52,656, respectively.   These  expenses
represent  direct payments to third parties for legal and  filing
fees,  direct administrative costs, outside audit and  accounting
costs,  insurance  and other property  costs.   The  increase  in
these  expenses in 1998, when compared to 1997, is the result  of
expenses  incurred  in 1998 related to the Media  Play  situation
discussed above.

        The  Partnership distributes all of its net income during
the  offering  and  acquisition phases, and if net  income  after
deductions  for  depreciation  is  not  sufficient  to  fund  the
distributions,  the  Partnership may distribute  other  available
cash that constitutes capital for accounting purposes.

        As  of June 30, 1998, the Partnership's cash distribution
rate  was 8.0% on an annualized basis.  Distributions of Net Cash
Flow  to  the  General Partners are subordinated to  the  Limited
Partners as required in the Partnership Agreement.  As a  result,
99% of distributions were allocated to Limited Partners and 1% to
the General Partners.

       Since the Partnership has only recently purchased its real
estate,  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.

        AEI  Fund  Management, Inc. (AEI) performs all management
services  for  the Partnership.  AEI is currently  analyzing  its
computer hardware and software systems to determine what, if any,
resources  need to be dedicated regarding Year 2000 issues.   The
Partnership  does  not  anticipate  any  significant  operational
impact  or  incurring material costs as a result of AEI  becoming
Year 2000 compliant.

Liquidity and Capital Resources

       The Partnership's primary sources of cash will be proceeds
from  the  sale  of Units, investment income, rental  income  and
proceeds  from the sale of property.  Its primary  uses  of  cash
will  be  investment  in  real properties,  payment  of  expenses
involved  in  the  sale  of  units,  the  organization   of   the
Partnership, the management of properties, the administration  of
the Partnership, and the payment of distributions.

         Until   the   offering  of  Units  was  completed,   the
Partnership's primary source of cash flow was from  the  sale  of
Limited  Partnership Units.  The Partnership offered for sale  up
to  $24,000,000  of limited partnership interests  (the  "Units")
(24,000  Units  at  $1,000 per Unit) pursuant to  a  registration
statement effective February 1, 1995.  From February 1,  1995  to
April  14, 1995, the minimum number of Limited Partnership  Units
(1,500) needed to form the Partnership were sold and on April 14,
1995,  a  total of 2,937.444 Units ($2,937,444) were  transferred
into  the  Partnership.   On January 31,  1997,  the  Partnership
offering terminated when the maximum subscription limit of 24,000
Limited  Partnership  Units  ($24,000,000)  was  reached.    From
subscription  proceeds,  the Partnership  paid  organization  and
syndication  costs (which constitute a reduction of  capital)  of
$3,277,000.

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

        Before  the  acquisition of properties,  cash  flow  from
operating  activities  is  not significant.   Net  income,  after
adjustment for depreciation, is lower during the first few  years
of  operations as administrative expenses remain high and a large
amount  of the Partnership's assets remain invested on  a  short-
term  basis in lower-yielding cash equivalents.  Net income  will
become   the  largest  component  of  cash  flow  from  operating
activities  and  the  largest component of cash  flow  after  the
completion of the acquisition phase.

        The Partnership Agreement requires that all proceeds from
the  sale  of  Units be invested or committed  to  investment  in
properties  by  the  later of two years after  the  date  of  the
Prospectus or six months after termination of the offer and  sale
of  Units.  While the Partnership is purchasing properties,  cash
flow from investing activities (investment in real property) will
remain  negative  and will constitute the principal  use  of  the
Partnership's available cash flow.

        On March 14, 1997, the Partnership purchased a parcel  of
land in San Antonio, Texas for $1,032,299.  The land is leased to
Champps Americana, Inc. (Champps) under a Lease Agreement with  a
primary  term of 20 years and annual rental payments of  $83,451.
Effective  September 9, 1997, the annual rent  was  increased  to
$128,156.   Simultaneously with the purchase  of  the  land,  the
Partnership entered into a Development Financing Agreement  under
which   the  Partnership  advanced  funds  to  Champps  for   the
construction  of  a  Champps Americana restaurant  on  the  site.
Initially, the Partnership charged interest on the advances at  a
rate of 7.0%.  Effective September 9, 1997, the interest rate was
increased to 10.75%.  On December 23, 1997, after the development
was  completed, the Lease Agreement was amended to require annual
rental  payments of $296,023.  Total acquisition costs, including
the cost of the land, were $2,833,357.

        On  March  19, 1997, the Partnership purchased a  Denny's
restaurant in Covington, Louisiana for $1,304,949.  The  property
is  leased  to Huntington Restaurants Group, Inc. under  a  Lease
Agreement  with  a  primary term of 20 years  and  annual  rental
payments of $141,243.

        On  April  21,  1997, the Partnership purchased  a  49.6%
interest  in  a  parcel  of  land  in  Schaumburg,  Illinois  for
$876,387.   The land is leased to Champps under a Lease Agreement
with  a  primary term of 20 years and annual rental  payments  of
$66,906.   Effective  October  17,  1997,  the  annual  rent  was
increased to $102,749.  Simultaneously with the purchase  of  the
land,  the  Partnership  entered  into  a  Development  Financing
Agreement  under which the Partnership advanced funds to  Champps
for  the  construction of a Champps Americana restaurant  on  the
site.   Initially,  the  Partnership  charged  interest  on   the
advances  at  a  rate of 7.0%.  Effective October 17,  1997,  the
interest  rate  was increased to 10.75%.  On December  31,  1997,
after  the  development was completed, the  Lease  Agreement  was
amended  to  require  annual rental payments  of  $236,479.   The
Partnership's share of the total acquisition costs, including the
cost of the land, was $2,256,462.  The remaining interests in the
property  are  owned by AEI Net Lease Income  &  Growth  Fund  XX
Limited  Partnership  and Net Lease Income  &  Growth  Fund  84-A
Limited Partnership, affiliates of the Partnership.

        On  July  8, 1997, the Partnership purchased a parcel  of
land in Livonia, Michigan for $1,074,384.  The land is leased  to
Champps  under a Lease Agreement with a primary term of 20  years
and  annual  rental  payments of $75,207.  Effective  January  3,
1998,  the annual rent was increased to $115,496.  Simultaneously
with  the  purchase of the land, the Partnership entered  into  a
Development Financing Agreement under which the Partnership  will
advance  funds  to  Champps  for the construction  of  a  Champps
Americana  restaurant  on the site.  Initially,  the  Partnership
charged  interest on the advances at a rate of  7.0%.   Effective
January  3, 1998, the interest rate was increased to 10.75%.   On
May  19,  1998,  after the development was completed,  the  Lease
Agreement  was  amended  to  require annual  rental  payments  of
$429,135.   Total acquisition costs, including the  cost  of  the
land, were $4,110,406.


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

        On  July  31,  1997, the Partnership  purchased  a  93.1%
interest  in a Caribou Coffee store in Charlotte, North  Carolina
for  $1,310,598.   The  property  is  leased  to  Caribou  Coffee
Company, Inc. under a Lease Agreement with a primary term  of  18
years  and  annual  rental payments of $146,438.   The  remaining
interest in the property is owned by AEI Institutional Net  Lease
Fund '93 Limited Partnership, an affiliate of the Partnership.

        Through  June 30, 1998, the Partnership sold 34.3363%  of
its  interest  in the Champps Americana restaurant  in  Columbus,
Ohio,  in  five separate transactions to unrelated third parties.
The  Partnership received total net sale proceeds  of  $1,156,453
which  resulted in a total net gain of $276,488.  The total  cost
and  related accumulated depreciation of the interests  sold  was
$916,080  and  $36,115, respectively.  For the six  months  ended
June 30, 1998, the net gain was $169,937.

        During  the  first  six months of 1998,  the  Partnership
distributed $241,683 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  $10.04  per  Limited
Partnership Unit.  The remaining net sale proceeds will either be
reinvested  in  additional  properties  or  distributed  to   the
Partners in the future.

         After   completion   of  the  acquisition   phase,   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.   The  redemption
payments  generally are funded with cash that would  normally  be
paid  as  part  of  the  regular quarterly distributions.   As  a
result,  total  distributions  and  distributions  payable   have
fluctuated  from year to year due to cash used to fund redemption
payments.

        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  1997, three Limited Partners redeemed a total  of
171.1  Partnership  Units for $154,021  in  accordance  with  the
Partnership  Agreement.   The Partnership  acquired  these  Units
using  Net  Cash Flow from operations.  The redemptions  increase
the   remaining  Limited  Partners'  ownership  interest  in  the
Partnership.

        Until  capital is invested in properties, the Partnership
will  remain liquid.  At June 30, 1998, $1,386,877 or 7%  of  the
Partnership's assets were in cash or cash equivalents  (including
accrued  interest  receivable).   After  completion  of  property
acquisitions,  the Partnership will attempt to  maintain  a  cash
reserve  of  only  approximately  1%  of  subscription  proceeds.
Because properties are purchased for cash and leased under triple-
net   leases,  this  is  considered  adequate  to  satisfy   most
contingencies.
