                  NOTES TO FINANCIAL STATEMENTS
                         MARCH 31, 2007

                           (Unaudited)

(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.

     by  AEI  Fund  Management XVIII, Inc.  (AFM),  the  Managing
     General Partner.  Robert P. Johnson, the President and  sole
     director  of AFM, serves as the Individual General  Partner.
     AFM  is a wholly owned subsidiary of AEI Capital Corporation
     of  which Mr. Johnson is the majority shareholder.  AEI Fund
     Management,  Inc. (AEI), an affiliate of AFM,  performs  the
     administrative and operating functions for the Partnership.

     The   terms  of  the  Partnership  offering  called  for   a
     subscription  price of $1,000 per Limited Partnership  Unit,
     payable   on  acceptance  of  the  offer.   The  Partnership
     commenced  operations  on February  15,  1989  when  minimum
     subscriptions    of   1,500   Limited   Partnership    Units

     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 l% to the General Partners  until  the
     Limited  Partners  receive an amount  equal  to:  (a)  their
     Adjusted Capital Contribution plus (b) an amount equal to 6%
     of their Adjusted Capital Contribution per annum, cumulative
     but not compounded, to the extent not previously distributed
     from  Net  Cash Flow; (ii) next, 99% to the Limited Partners
     and  1%  to the General Partners until the Limited  Partners
     receive  an  amount equal to 14% of their  Adjusted  Capital
     Contribution  per annum, cumulative but not  compounded,  to
     the  extent not previously distributed; (iii) next,  to  the
     General  Partners  until  cumulative  distributions  to  the
     General  Partners under Items (ii) and (iii)  equal  15%  of
     cumulative  distributions to all Partners under  Items  (ii)
     and (iii).  Any remaining balance will be distributed 85% to
     the  Limited  Partners  and  15% 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 90%  to
     the Limited Partners and 10% to the General Partners. In the
     event  no  Net  Cash  Flow  is distributed  to  the  Limited
     Partners,  90%  of each item of income, gain or  credit  for
     each  respective  year  shall be allocated  to  the  Limited
     Partners,  and 10% of each such item shall be  allocated  to
     the  General Partners.  Net losses from operations  will  be
     allocated 98% to the Limited Partners and 2% 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 14% of their Adjusted Capital Contributions
     per  annum, cumulative but not compounded, to the extent not
     previously  allocated; (iii) third, to the General  Partners
     until  cumulative allocations to the General Partners  equal
     15%  of cumulative allocations.  Any remaining balance  will
     be  allocated  85% to the Limited Partners and  15%  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.

ITEM 2.MANAGEMENT'S DISCUSSION AND ANALYSIS

        The Management's Discussion and Analysis contains various
"forward  looking  statements"  within  the  meaning  of  federal
securities  laws  which  represent management's  expectations  or
beliefs  concerning future events, including statements regarding
anticipated  application of cash, expected  returns  from  rental
income,  growth  in  revenue, the sufficiency  of  cash  to  meet
operating  expenses, rates of distribution,  and  other  matters.
These,   and  other  forward  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 the Partners;

    resolution  by  the General Partners of  conflicts  with
    which they may be confronted;

    the effect of tenant defaults; and

    the  condition of the industries in which the  tenants  of
    properties owned by the Partnership operate.


The Application of Critical Accounting Policies

        The preparation of the Partnership's financial statements
requires  management to make estimates and assumptions  that  may
affect the reported amounts of assets, liabilities, revenues  and
expenses,  and  related  disclosure  of  contingent  assets   and
liabilities. Management evaluates these estimates on  an  ongoing
basis,  including  those related to the carrying  value  of  real
estate  and  the  allocation  by AEI  Fund  Management,  Inc.  of
expenses  to  the  Partnership as opposed  to  other  funds  they
manage.

        The Partnership purchases properties and records them  in
the  financial  statements  at the lower  of  cost  or  estimated
realizable   value.   The  Partnership  initially   records   the
properties  at cost (including capitalized acquisition expenses).
The Partnership is required to periodically evaluate the carrying
value  of properties to determine whether their realizable  value
has  declined.   For  properties the Partnership  will  hold  and
operate, management determines whether impairment has occurred by
comparing the property's probability-weighted cash flows  to  its
current carrying value.  For properties held for sale, management
determines  whether  impairment has  occurred  by  comparing  the
property's estimated fair value less cost to sell to its  current
carrying  value.   If  the carrying value  is  greater  than  the
realizable  value, an impairment loss is recorded to  reduce  the
carrying value of the property to its realizable value.  A change
in  these assumptions or analysis could cause material changes in
the carrying value of the properties.

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

        AEI  Fund Management, Inc. allocates expenses to each  of
the  funds  they manage primarily on the basis of the  number  of
hours  devoted  by their employees to each fund's affairs.   They
also  allocate  expenses at the end of each month  that  are  not
directly related to a fund's operations based upon the number  of
investors  in the fund and the fund's capitalization relative  to
other  funds  they  manage.   The  Partnership  reimburses  these
expenses  subject  to  detailed  limitations  contained  in   the
Partnership Agreement.

         Management   of  the  Partnership  has   discussed   the
development  and selection of the above accounting estimates  and
the management discussion and analysis disclosures regarding them
with the managing partner of the Partnership.

Results of Operations

        For  the three months ended March 31, 2007 and 2006,  the
Partnership  recognized rental income from continuing  operations
of  $125,069 and $123,424, respectively.  In 2007, rental  income
increased due to rent increases on two properties.

        For  the three months ended March 31, 2007 and 2006,  the
Partnership  incurred  Partnership administration  expenses  from
affiliated  parties of $29,334 and $35,292, respectively.   These
administration  expenses  include  costs  associated   with   the
management of the properties, processing distributions, reporting
requirements and correspondence to the Limited Partners.  As  the
Partnership's asset base decreases due to property sales,  it  is
allocated a smaller share of expenses that are allocated  by  AEI
Fund  Management, Inc. based on the relative assets of the  funds
under  management.   During  the same  periods,  the  Partnership
incurred   Partnership  administration  and  property  management
expenses   from   unrelated  parties  of   $9,749   and   $9,934,
respectively.  These expenses represent direct payments to  third
parties  for legal and filing fees, direct administrative  costs,
outside audit costs, taxes, insurance and other property costs.

        For  the three months ended March 31, 2007 and 2006,  the
Partnership  recognized interest income of $11,049  and  $25,763,
respectively.  In 2006, interest income was higher mainly due  to
the  Partnership  having more money invested in  a  money  market
account   due  to  property  sales.   The  sales  proceeds   were
subsequently distributed to the Partners.

        In  accordance  with  Statement of  Financial  Accounting
Standards  No. 144, Accounting for the Impairment or Disposal  of
Long-Lived  Assets,  upon  complete disposal  of  a  property  or
classification of a property as Real Estate Held  for  Sale,  the
Partnership  includes  the operating  results  and  sale  of  the
property   in   discontinued  operations.    In   addition,   the
Partnership reclassifies the prior periods operating results  and
any  partial  sales  of the property to discontinued  operations.
For  the  three  months  ended March 31,  2007,  the  Partnership
recognized  income  from  discontinued  operations  of  $116,553,
representing  rental income of $34,788 and gain  on  disposal  of
real  estate  of $81,765.  For the three months ended  March  31,
2006,   the   Partnership  recognized  income  from  discontinued
operations of $627,478, representing rental income less  property
management  expenses  and depreciation of $142,508  and  gain  on
disposal of real estate of $484,970.

On  January  26,  2006,  the  sale closed  with  the  Partnership
receiving  net sale proceeds of $1,642,624, which resulted  in  a
net  gain of $484,970.  At the time of sale, the cost and related
accumulated    depreciation   was   $1,406,426   and    $248,772,
respectively.

        In May 2006, the Partnership entered into an agreement to
sell the Children's World daycare center in Lenexa, Kansas to  an
unrelated third party.  On August 14, 2006, the Partnership  sale
closed  with  the  Partnership receiving  net  sale  proceeds  of
$849,224, which resulted in a net gain of $306,488.  At the  time
of  sale,  the  cost  and  related accumulated  depreciation  was
$983,527 and $440,791, respectively.

        During 2006, the Partnership sold its 50% interest in the
Jared  Jewelry  store in Lakewood, Colorado,  in  seven  separate
transactions,  to  unrelated  third  parties.   The   Partnership
received total net sale proceeds of $2,382,658, which resulted in
a  net  gain  of  $450,831.   The cost  and  related  accumulated
depreciation  of the interests sold was $2,017,633  and  $85,806,
respectively.  For the three months ended March 31, 2006, the net
gain was $-0-.

       On November 3, 2006, the Partnership sold its 24% interest
in  the  Garden  Ridge  retail store in Woodlands,  Texas  to  an
unrelated  third  party.   The  Partnership  received  net   sale
proceeds of $2,094,119, which resulted in a net gain of $245,256.
At   the   time   of  sale,  the  cost  and  related  accumulated
depreciation was $1,995,850 and $146,987, respectively.

        On  August 28, 2006, the Partnership sold 6.869%  of  the
Eckerd  drug  store  in Auburn, New York to  an  unrelated  third
party.   The Partnership received net sale proceeds of  $376,203,
which  resulted in a net gain of $76,398.  The cost  and  related
accumulated  depreciation of the interest sold was  $314,206  and
$14,401, respectively.

        During  the  first three months of 2007, the  Partnership
sold  12.2927% of the Eckerd drug store in Auburn, New  York,  in
three  separate  transactions, to unrelated third  parties.   The
Partnership  received total net sale proceeds of $618,294,  which
resulted  in  a  net  gain  of $81,765.   The  cost  and  related
accumulated  depreciation of the interests sold was $562,301  and
$25,772, respectively.  The Partnership is attempting to sell its
remaining 30.8383% interest in the property.  At March  31,  2007
and December 31, 2006, the property was classified as Real Estate
Held  for  Sale  with a book value of $1,345,972 and  $1,882,501,
respectively.

        In the second quarter of 2005, the Partnership decided to
discontinue the reinvestment of proceeds from property  sales  in
additional  properties.   As a result, the  Partnership's  rental
income  and operating income will decrease in the future  as  the
Partnership sells its remaining properties.

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

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

Liquidity and Capital Resources

       During the three months ended March 31, 2007 and 2006, the
Partnership's cash balances decreased $1,973,242 and  $1,761,628,
respectively, as a result of distributions paid to  the  Partners
in   excess  of  cash  generated  from  operating  and  investing
activities.

        Net  cash provided by operating activities decreased from
$238,391  in 2006 to $125,400 in 2007 due to a decrease in  total
rental and interest income in 2007, which was partially offset by
a  decrease in Partnership administration and property management
expenses in 2007 and net timing differences in the collection  of
payments from tenants and the payment of expenses.

       During the three months ended March 31, 2007 and 2006, the
Partnership generated cash flow from the sale of real  estate  of
$618,294 and $1,642,624, respectively.

       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 on a quarterly basis.

        For  the three months ended March 31, 2007 and 2006,  the
Partnership  declared distributions of $148,454  and  $2,002,740,
respectively, which were distributed 99% to the Limited  Partners
and  1%  to the General Partners.  The Limited Partners  received
distributions of $146,970 and $1,982,712 and the General Partners
received  distributions of $1,484 and $20,028  for  the  periods,
respectively.  In March, June, September and December  2006,  the
Partnership  declared special distributions of net sale  proceeds
of $1,717,172, $505,051, $3,030,303 and $2,525,253, respectively,
which  resulted  in  higher distributions in 2006  and  a  higher
distribution payable at December 31, 2006.

        During  the  first  three months of 2007  and  2006,  the
Partnership  distributed  $16,631  and  $1,736,394  of  net  sale
proceeds  to  the Limited and General Partners as part  of  their
quarterly distributions, which represented a return of capital of
$0.87 and $90.21 per Limited Partnership Unit, respectively.

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.

       On January 1, 2006, four Limited Partners redeemed a total
of  27  Partnership  Units for $18,444  in  accordance  with  the
Partnership  Agreement.   The Partnership  acquired  these  Units
using Net Cash Flow from operations.  In prior years, a total  of
294  Limited  Partners  redeemed 3,699.92 Partnership  Units  for
$3,087,902.   The  redemptions  increase  the  remaining  Limited
Partners' ownership interest in the Partnership.  As a result  of
these   redemption  payments  and  pursuant  to  the  Partnership
Agreement, the General Partners received distributions of $186 in
2006.

       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.

ITEM 3.   CONTROLS AND PROCEDURES.

       (a) Evaluation of disclosure controls and procedures

        Under  the  supervision  and with  the  participation  of
management, including its President and Chief Financial  Officer,
the  Managing  General Partner of the Partnership  evaluated  the
effectiveness  of  the  design and operation  of  its  disclosure
controls  and procedures (as defined in Rule 13a-14(c) under  the
Exchange  Act).   Based upon that evaluation, the  President  and
Chief Financial Officer of the Managing General Partner concluded
that,  as  of  the end of the period covered by this report,  the
disclosure  controls  and  procedures  of  the  Partnership   are
adequately  designed to ensure that information  required  to  be
disclosed  by  us  in  the reports we file or  submit  under  the
Exchange  Act  is recorded, processed, summarized  and  reported,
within  the time periods specified in applicable rules and  forms
and  that  such  information is accumulated and  communicated  to
management,  including the President and Chief Financial  Officer
of  the  Managing General Partner, in a manner that allows timely
decisions regarding required disclosure.

       (b)  Changes in internal controls

         There   were   no  significant  changes  made   in   the
Partnership's  internal controls during the  most  recent  period
covered  by  this  report that have materially affected,  or  are
reasonably   likely  to  materially  affect,  the   Partnership's
internal control over financial reporting.

the  repurchase  dates of January 1st, April 1st,  July  1st  and

of  the number of Units outstanding at the beginning of the year.

if,  in the sole discretion of the Managing General Partner, such
