     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 AEI Real  Estate  Fund  XVIII
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, via first  class
mail,  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 commitment  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 in paragraph  11  below;
and  other  items of record disclosed to Buyer during the  Review
Period.

      Buyer shall be allowed ten (10) 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.

     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  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 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
     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

     applicable   local,  state  and  federal  laws,  ordinances,
     regulations and requirements.
     
     (c)   Seller  knows  of no facts nor has  Seller  failed  to
     disclose  to  Buyer  any fact known to  Seller  which  would
     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,

     with  the Property either before or after the Closing  Date,
     except such Hazardous Materials on or in connection with the
     Property  arising  out  of  Seller's  gross  negligence   or
     intentional misconduct.
     
     (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 Property  and  such  financial
     information  on the Lessee and Guarantors of  the  Lease  as
     Buyer or its advisors shall request, 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

     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.   The  sale  of the Property  as  provided  for
     herein  is  made  on an "AS IS" basis, and  Buyer  expressly

     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
     should  be  destroyed  or  further  damaged  by  fire,   the

     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

     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 Starker Services, Inc. who

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

     in  breach and stating that this Contract shall be cancelled
     unless  the  breach  is cured within 13 days  following  the
