     (e) Evidence of zoning compliance.
     
     (f) Soils report.
     
     (g) Environmental report.
     
     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 and Seller 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 sections 15(a) 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 have canceled this  Agreement  and
relinquish  all rights in and to the Property unless Buyer  makes
the  Second  Payment  when required.  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 definded in paragraph 11  below;
and  other  items of record 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 in a manner  satisfactory  to
Buyer.   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



     Buyer Initial: /s/ Vh /s/ MCC
     Purchase Agreement for Champps-Columbus, OH




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.

     Pending correction of title, the payments hereunder required
shall  be postponed, but upon correction of title and within  ten
(10)  days  after written notice of correction 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 and any brokerage commissions
payable.   The  Buyer  will pay the cost of  issuing  a  Standard
Owners  Title Insurance Policy in the full amount of the purchase
price,  if  Buyer shall decide to purchase the same.  Buyer  will
pay all recording fees, one-half of the escrow fees, 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 and shall be responsible for its proportionate  shall
     of all operating expenses of the Entire Property incurred on
     and after the date of closing.
     
     The provisions of (a) and (b) above shall survive closing.
     
11.  Seller's Representation and Agreements.

      (a)   Seller represents and warrants as of this  date  (and
such   shall  survive  closing  for  a    period  of  18   months
thereafter) that:

     (i)  Except for the lease in existence between AEI Income  &
     Growth Fund XXI Limited Partnership and AEI Real Estate Fund
     XVIII  Limited Partnership and Americana Dining Corporation,
     dated August 29, 1996, Seller is not aware of any leases  of
     the Property.  The above referenced lease agreement also has
     a first right of refusal in favor of the Tenant as set forth
     in  Article  34 of said lease agreement, which  right  shall
     apply  to any attempted disposition of the 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  set
     forth  in  paragraph (b) below, Seller is not aware  of  any
     contracts Seller has executed that would be binding on Buyer

     (iv)  In  addition to the acts and deeds recited herein  and
     contemplated  to  be performed, executed, and  delivered  by
     Seller,  Seller shall perform, execute and deliver or  cause
     to  be performed, executed, and delivered at the Closing  or
     after  the  Closing,  any and all further  acts,  deeds  and
     assurances as Buyer or the Title Company may require and  be
     reasonable   in   order  to  consummate   the   transactions
     contemplated herein.
     
     (v)   Seller  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.
     
     (vi)   To  Seller's  knowledge, neither  the  execution  and

     order  of  any  court or other agency of  government  having
     jurisdiction  hereof, or (c) any agreement or instrument  to
     which Seller is a party or by which Seller is bound.
          
     (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)   To the best of Seller's knowledge: there are now,  and
     at  the  Closing  there  will be, no material,  physical  or

     prevent  Buyer  from using and operating the Property  after
     the  Closing  in the manner in which the Property  has  been
     used and operated prior to the date of this Agreement.
     
     (d)  To the best of Seller's knowledge: the Property is not,

     (i)   In  addition to the acts and deeds recited herein  and
     contemplated  to  be performed, executed, and  delivered  by
     Buyer, Buyer shall perform, execute and deliver or cause  to
     be  performed,  executed, and delivered at  the  Closing  or

     contemplated herein.
     
     (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
     delivery  of  this  Agreement nor the  consummation  of  the
     transaction  contemplated  hereby  will  violate  or  be  in
     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.

     Purchase Agreement for Champps-Columbus, OH
     
     
     
     
     
     (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
