     (d) Lease (as further set forth in paragraph 11(a) below) of
     the Entire Property showing occupancy date, lease expiration
     date,  rent,  and  Guaranty's, if any, accompanied  by  such
     tenant  financial statements as may have been provided  most
     recently to Seller by the Tenant and/or Guarantors.

     It is a contingency upon Seller's obligations hereunder that
two  (2)  copies  of  Co-Tenancy Agreement in the  form  attached
hereto  duly  executed by Buyer, AEI Income  &  Growth  Fund  XXI
Limited  Partnership,  and  dated  on  escrow  closing  date   be
delivered to the Seller on the closing date.

      Buyer may cancel this agreement for ANY REASON in its  sole
discretion  by  delivering a cancellation notice, return  receipt
requested,  to Seller and escrow holder before the expiration  of
the  Review  Period. Such notice shall be deemed  effective  only
upon  receipt  by Seller.  If this Agreement is not cancelled  as
set forth above, the First Payment shall be non-refundable unless
Seller shall default hereunder.

      If  Buyer  cancels this Agreement as permitted  under  this
Section,  except  for  any  escrow  cancellation  fees  and   any
liabilities  under  the first paragraph  of  section  6  of  this
agreement  (which will survive), Buyer (after execution  of  such
documents   reasonably  requested  by  Seller  to  evidence   the
termination  hereof)  shall be returned its  First  Payment,  and
Buyer  will have absolutely no rights, claims or interest of  any
type  in  connection  with  the  Property  or  this  transaction,
regardless of any alleged conduct by Seller or anyone else.

      Unless this Agreement is canceled by Buyer pursuant to  the
terms  hereof, if Buyer fails to make the Second Payment,  Seller
shall   be  entitled  to  retain  the  First  Payment  and  Buyer
irrevocably will be deemed to be in default under this Agreement.
Seller  may, at its option, retain the First Payment and  declare
this Agreement null and void, in which event Buyer will be deemed
to  have canceled this Agreement and relinquish all rights in and
to  the  Property or Seller may exercise its rights under Section
14  hereof.   If  this Agreement is not canceled and  the  Second
Payment  is  made  when required, all of Buyer's  conditions  and
contingencies will be deemed satisfied.

7.  ESCROW. Escrow shall be opened by Seller and funds  deposited
in  escrow upon acceptance of this Agreement by both parties. The
escrow  holder  will  be a nationally recognized  escrow  company
selected by Seller. A copy of this Agreement will be delivered to
the  escrow holder and will serve as escrow instructions together
with the escrow holder's standard instructions and any additional
instructions required by the escrow holder to clarify its  rights
and  duties  (and  the  parties agree to  sign  these  additional
instructions).  If  there  is any conflict  between  these  other
instructions and this Agreement, this Agreement will control.

8.   TITLE.  Closing will be conditioned on the  agreement  of  a
title  company selected by Seller to issue an Owner's  policy  of
title insurance, dated as of the close of escrow, in
an  amount equal to the purchase price, insuring that Buyer  will
own  insurable title to the Property subject only to:  the  title
company's  standard exceptions; current real property  taxes  and
assessments;  survey  exceptions;  the  rights  of   parties   in
possession pursuant to the lease defined




     Buyer Initial: /s/ NG
     Purchase Agreement for Champps Americana Restaurant - Schaumburg, IL



in  paragraph 11 below; all matters of public record;  and  other
items disclosed to Buyer during the Review Period.

      Buyer shall be allowed five (5) days after receipt of  said
commitment  for examination and the making of any  objections  to
marketability thereto, said objections to be made in  writing  or
deemed  waived.  If any objections are so made, the Seller  shall
be  allowed eighty (80) days to make such title marketable or  in
the  alternative  to  obtain  a commitment  for  insurable  title
insuring over Buyer's objections.  If Seller shall decide to make
no  efforts to make title marketable, or is unable to make  title
marketable or obtain insurable title, (after execution  by  Buyer
of  such documents reasonably requested by Seller to evidence the
termination  hereof) Buyer's First Payment shall be returned  and
this Agreement shall be null and void and of no further force and
effect.  Seller has no obligation to spend any funds or make  any
effort to satisfy Buyer's objections, if any.

      Pending  satisfaction of Buyer's objections,  the  payments
hereunder  required shall be postponed, but upon satisfaction  of
Buyer's objections and within ten (10) days after written  notice
of  satisfaction of Buyer's objections to the Buyer, the  parties
shall perform this Agreement according to its terms.

9.   CLOSING COSTS.  Seller will pay one-half of escrow fees, the
cost  of the title commitment, one-half of the cost of issuing  a
Standard Owners Title Insurance Policy, in the full amount of the
purchase  price,  and any brokerage commissions  payable.   Buyer
will  pay  all recording fees, one-half of the escrow fees,  one-
half  of  the  cost of issuing a Standard Owners Title  Insurance
Policy, in the full amount of the purchase price, and the cost of
an  update  to the Survey in Sellers possession (if an update  is
required by Buyer.)  Each party will pay its own attorney's  fees
and costs to document and close this transaction.

10.  REAL ESTATE TAXES, SPECIAL ASSESSMENTS AND PRORATIONS.

     (a)  Because the Entire Property (of which the Property is a
     part) is subject to a triple net lease (as further set forth
     in  paragraph 11(a)(i), the parties acknowledge  that  there
     shall  be no need for a real estate tax proration.  However,
     Seller  represents  that to the best of its  knowledge,  all
     real  estate  taxes and installments of special  assessments
     due  and  payable in all years prior to the year of  Closing
     have been paid in full.  Unpaid real estate taxes and unpaid
     levied and pending special assessments existing on the  date
     of  Closing shall be the responsibility of Buyer and  Seller
     in   proportion  to  their  respective  Tenant   in   Common
     interests,  pro-rated, however, to the date of  closing  for
     the   period   prior  to  closing,  which   shall   be   the
     responsibility of Seller if Tenant shall not pay  the  same.
     Seller  and  Buyer  shall likewise pay  all  taxes  due  and
     payable   in   the  year  after  Closing  and   any   unpaid
     installments  of special assessments payable  therewith  and
     thereafter,  if  such  unpaid  levied  and  pending  special
     assessments and real estate taxes are not paid by any tenant
     of the Entire Property.

     (b)   All  income and all operating expenses from the Entire
     Property shall be prorated between  the parties and adjusted
     by them as of the date of  Closing. Seller shall be entitled
     to  all income earned  and  shall  be  responsible  for  all
     expenses incurred prior to  the date  of Closing, and  Buyer
     shall be entitled  to  its proportionate share of all income
     earned




     Buyer Initial: /s/ NG
     Purchase Agreement for Champps Americana Restaurant - Schaumburg, IL





     and  shall be responsible, only if Tenant shall not pay, for
     its  proportionate share of all operating  expenses  of  the
     Entire Property incurred on and after the date of closing.



11.  SELLER'S REPRESENTATION AND AGREEMENTS.

     (a)  Seller represents and warrants as of this date that:

     (i)  Except for the Lease Agreement in existence between AEI
Income  &  Growth  Fund XXI Limited Partnership,  AEI  Net  Lease

Champps  Americana,  Inc. ("Tenant"), dated April  21,  1997  and
amended  on December 31, 1997, Seller is not aware of any  leases
of  the  Property.  The above referenced lease  agreement  has  a
right  of  first refusal in favor of the Tenant as set  forth  in
Article 34 of said lease agreement, which right will apply to any
attempted   disposition  of  Property   by   Buyer   after   this
transaction.

     (ii)   It  is  not  aware  of  any  pending  litigation   or
     condemnation  proceedings against the Property  or  Seller's
     interest in the Property.

     (iii)   Except  as  previously disclosed  to  Buyer  and  as
     permitted in paragraph (b) below, Seller is not aware of any
     contracts Seller has executed that would be binding on Buyer
     after the closing date.

     (b)   Provided  that  Buyer performs  its  obligations  when
     required, Seller agrees that it will not enter into any  new
     contracts that would materially affect the Property  and  be
     binding  on  Buyer  after the Closing Date  without  Buyer's
     prior  consent,  which  will not be  unreasonably  withheld.
     However,  Buyer acknowledges that Seller retains  the  right
     both  prior to and after the Closing Date to freely transfer
     all or a portion of Seller's remaining undivided interest in
     the  Entire Property, provided such sale shall not  encumber
     the  Property being purchased by Buyer in violation  of  the
     terms hereof or the contemplated Co-Tenancy Agreement.

12.  DISCLOSURES.

     (a)   Seller  has not received any notice of  any  material,
     physical,  or  mechanical defects of  the  Entire  Property,
     including  without  limitation, the plumbing,  heating,  air
     conditioning, ventilating, electrical system. To the best of
     Seller's  knowledge without inquiry, all such items  are  in
     good  operating condition and repair and in compliance  with
     all  applicable  governmental, zoning, and  land  use  laws,
     ordinances,  regulations and requirements.  If Seller  shall
     receive any notice to the contrary prior to Closing,  Seller
     will inform Buyer prior to Closing.

     (b)  Seller  has  not received any notice that the  use  and
     operation of the Entire Property
     is  not  in full compliance with applicable building  codes,
     safety,   fire,  zoning,  and  land  use  laws,  and   other
     applicable   local,  state  and  federal  laws,  ordinances,
     regulations and



     Buyer Initial: /s/ NG
     Purchase Agreement for Champps Americana Restaurant - Schaumburg, IL




     requirements.   If Seller shall receive any  notice  to  the
     contrary prior to Closing, Seller will inform Buyer prior to
     Closing.

     (c)   Seller  knows  of no facts nor has  Seller  failed  to
     disclose  to  Buyer  any fact known to  Seller  which  would
     prevent  the  Tenant  from using and  operating  the  Entire
     Property after the Closing in the manner in which the Entire
     Property  has been used and operated prior to  the  date  of
     this  Agreement.  If Seller shall receive any notice to  the
     contrary prior to Closing, Seller will inform Buyer prior to
     Closing.

     (d)   Seller  has  not received any notice that  the  Entire
     Property is in violation of any federal, state or local law,

     Property,   including,  but  not  limited  to,   soil,   and
     groundwater conditions.  To the best of Seller's  knowledge,
     there  is  no  proceeding  or inquiry  by  any  governmental
     authority   with  respect  to  the  presence  of   Hazardous
     Materials  on  the  Entire  Property  or  the  migration  of
     Hazardous Materials from or to other property.  Buyer agrees
     that  Seller will have no liability of any type to Buyer  or
     Buyer's  successors,  assigns, or affiliates  in  connection
     with  any  Hazardous Materials on or in connection with  the
     Entire  Property  either before or after the  Closing  Date,
     except such Hazardous Materials on or in connection with the
     Entire Property arising out of Seller's gross negligence  or
     intentional misconduct.  If Seller shall receive any  notice
     to  the contrary prior to Closing, Seller will inform  Buyer
     prior to Closing.

     (e)   BUYER AGREES THAT IT SHALL BE PURCHASING THE  PROPERTY
     IN  ITS  THEN PRESENT CONDITION, AS IS, WHERE IS, AND SELLER
     HAS  NO  OBLIGATIONS TO CONSTRUCT OR REPAIR ANY IMPROVEMENTS
     THEREON  OR TO PERFORM ANY OTHER ACT REGARDING THE PROPERTY,
     EXCEPT AS EXPRESSLY PROVIDED HEREIN.

     (f)    BUYER  ACKNOWLEDGES  THAT,  HAVING  BEEN  GIVEN   THE
     OPPORTUNITY  TO  INSPECT  THE  ENTIRE  PROPERTY   AND   SUCH
     FINANCIAL  INFORMATION ON THE LESSEE AND GUARANTORS  OF  THE
     LEASE AS BUYER OR ITS ADVISORS SHALL REQUEST, IF IN SELLER'S
     POSSESSION, BUYER IS RELYING SOLELY ON ITS OWN INVESTIGATION
     OF  THE  PROPERTY  AND  NOT ON ANY INFORMATION  PROVIDED  BY
     SELLER OR TO BE PROVIDED EXCEPT AS SET FORTH HEREIN.   BUYER
     FURTHER ACKNOWLEDGES THAT THE INFORMATION PROVIDED AND TO BE
     PROVIDED BY SELLER WITH RESPECT TO THE PROPERTY, THE  ENTIRE
     PROPERTY  AND  TO  THE LESSEE AND GUARANTORS  OF  LEASE  WAS
     OBTAINED  FROM A VARIETY OF SOURCES AND SELLER  NEITHER  (A)
     HAS  MADE INDEPENDENT INVESTIGATION OR VERIFICATION OF  SUCH
     INFORMATION,  OR  (B) MAKES ANY REPRESENTATIONS  AS  TO  THE
     ACCURACY  OR  COMPLETENESS  OF SUCH  INFORMATION  EXCEPT  AS
     HEREIN SET FORTH.  THE SALE OF THE PROPERTY AS PROVIDED  FOR
     HEREIN  IS  MADE  ON AN "AS IS" BASIS, AND  BUYER  EXPRESSLY
     ACKNOWLEDGES  THAT, IN CONSIDERATION OF  THE  AGREEMENTS  OF
     SELLER  HEREIN,  EXCEPT  AS OTHERWISE  SPECIFIED  HEREIN  IN
     PARAGRAPH 11(A) AND (B) ABOVE AND THIS PARAGRAPH 12,  SELLER
     MAKES NO WARRANTY OR REPRESENTATION, EXPRESS OR IMPLIED,  OR
     ARISING BY OPERATION OF LAW, INCLUDING, BUT NOT LIMITED  TO,

     If Seller shall default, Buyer irrevocably waives any rights
to file a lis pendens, a specific performance action or any other
claim,  action or proceeding of any type in connection  with  the
Property or this or any other transaction involving the Property,
and  will  not  do  anything to affect title to the  Property  or

     (ii)   Buyer  has  all  requisite  power  and  authority  to
     consummate  the  transaction contemplated by this  Agreement
     and  has by proper proceedings duly authorized the execution
     and  delivery of this Agreement and the consummation of  the
     transaction contemplated hereby.

     (iii)   To  Buyer's  knowledge, neither  the  execution  and

     conflict with (a) any applicable provisions of law, (b)  any
     order  of  any  court or other agency of  government  having
     jurisdiction  hereof, or (c) any agreement or instrument  to
     which Buyer is a party or by which Buyer is bound.

16.  DAMAGES, DESTRUCTION AND EMINENT DOMAIN.

     (a)   If, prior to closing, the Property or any part thereof
     be  destroyed  or further damaged by fire, the elements,  or
     any cause, due to events occurring subsequent to the date of
     this Agreement to the extent that the cost of repair exceeds
     $10,000.00,  this Agreement shall become null and  void,  at
     Buyer's  option exercised, if at all, by written  notice  to
     Seller within ten (10) days after Buyer has received written
     notice  from Seller of said destruction or damage.   Seller,
     however,  shall  have  the right to  adjust  or  settle  any
     insured  loss  until  (i)  all contingencies  set  forth  in
     Paragraph 6 hereof have been satisfied, or waived; and  (ii)
     any  ten-day  period provided for above in this Subparagraph
     16a  for  Buyer  to  elect to terminate this  Agreement  has
     expired  or  Buyer has, by written notice to Seller,  waived
     Buyer's right to terminate this Agreement.  If Buyer  elects
     to  proceed  and  to  consummate the purchase  despite  said
     damage  or  destruction, there shall be no reduction  in  or
     abatement of the purchase price, and Seller shall assign  to
     Buyer the Seller's right, title, and interest in and to  all
     insurance  proceeds  (pro-rata in  relation  to  the  Entire
     Property) resulting from said damage or destruction  to  the
     extent  that the same are payable with respect to damage  to
     the  Property, subject to rights of any Tenant of the Entire
     Property.

     If  the cost of repair is less than $10,000.00, Buyer  shall
     be  obligated  to  otherwise  perform  hereinunder  with  no
     adjustment  to  the Purchase Price, reduction or  abatement,
     and  Seller shall assign Seller's right, title and  interest
     in and to all insurance proceeds pro-rata in relation to the
     Entire  Property,  subject to rights of any  Tenant  of  the
     Entire Property.

     (b)   If,  prior  to  closing, the  Property,  or  any  part
     thereof,  is  taken by eminent domain, this Agreement  shall
     become null and void, at Buyer's option.  If Buyer elects to
     proceed  and to consummate the purchase despite said taking,
     there  shall  be  no  reduction in,  or  abatement  of,  the
     purchase  price,  and  Seller  shall  assign  to  Buyer  the
     Seller's  right,  title, and interest in and  to  any  award
     made, or to be made, in the condemnation proceeding pro-rata
     in relation to the Entire Property, subject to rights of any
     Tenant of the Entire Property.

      In the event that this Agreement is terminated by Buyer  as
provided  above  in  Subparagraph 16a or 16b, the  First  Payment
shall  be immediately returned to Buyer (after execution by Buyer
of  such documents reasonably requested by Seller to evidence the
termination hereof).

17.  BUYER'S 1031 TAX FREE EXCHANGE.

      While  Seller  acknowledges that Buyer  is  purchasing  the
Property  as  "replacement property" to  accomplish  a  tax  free
exchange,   Buyer   acknowledges  that   Seller   has   made   no
representations,  warranties, or agreements to Buyer  or  Buyer's
agents  that  the transaction contemplated by the Agreement  will
qualify  for such tax treatment, nor has there been any  reliance
thereon by Buyer respecting the legal or tax implications of  the
transactions contemplated hereby.  Buyer further represents  that
it  has  sought and obtained such third party advice and counsel,
as  it deems necessary in regards to the tax implications of this
transaction.

      Buyer  wishes  to  novate/assign the ownership  rights  and
interest  of  this Purchase Agreement to TimCor who will  act  as
Accommodator  to  perfect  the  1031  exchange  by  preparing  an
agreement of exchange of Real Property whereby TimCor will be  an
independent  third  party purchasing the  ownership  interest  in
subject  property from Seller and selling the ownership  interest
in  subject property to Buyer under the same terms and conditions
as documented in this Purchase Agreement.  Buyer asks the Seller,
and  Seller  agrees  to cooperate in the perfection  of  such  an
exchange  if at no additional cost or expense to Seller or  delay
in time.  Buyer hereby indemnifies and holds Seller harmless from
any claims and/or actions resulting from said exchange.  Pursuant
to  the  direction of TimCor, Seller will deed  the  property  to
Buyer.

18.  CANCELLATION

     If  any party elects to cancel this Contract because of  any
     breach by another party or because escrow fails to close  by
     the  agreed date, the party electing to cancel shall deliver
     to escrow agent a notice containing the address of the party
     in  breach and stating that this Contract shall be cancelled
     unless  the  breach  is cured within 13 days  following  the
     delivery  of  the notice to the escrow agent.  Within  three
     days  after  receipt of such notice, the escrow agent  shall
     send it by United States Mail to the party in breach at  the
     address contained in the Notice and no further notice  shall
     be  required. If the breach is not cured within the 13  days
