Section 2 - Financial Information

Item 2.01 Completion of Acquisition or Disposition of Assets.

      On October 6, 2008, the Company purchased a 33% interest in
a  Best  Buy store in Lake Geneva, Wisconsin for $1,991,220  from
Ryan  Companies US, Inc., an unrelated third party.  The property
is leased to Best Buy Stores, L.P. under a Lease Agreement with a
remaining  primary term of 10.3 years.  The Lease may be  renewed
by  the  tenant  for up to four consecutive terms of  five  years
each.  The Lease requires an initial annual rent of $144,325  for
the  33%  interest,  which  will increase  every  five  years  by
approximately  3.4%.  The Lease is a net lease  under  which  the
tenant   is   responsible  for  real  estate  taxes,   insurance,
maintenance, repairs and operating expenses of the property.  The
only exceptions are the Company is responsible for repairs to the
structural components of the building, roof, and parking lot  and
replacement  of  HVAC,  electrical, plumbing  and  other  similar
systems  for  the  building.   The  remaining  interests  in  the
property were purchased by AEI Income & Growth Fund XXII  Limited
Partnership  and AEI Income & Growth Fund 24 LLC,  affiliates  of
the Company.

       The Company purchased the property with cash received from
the sale of LLC Units.  The store was constructed in 2008 and  is
a 30,376 square foot building situated on approximately 3.8 acres
of  land.  The freestanding retail store is located at 700  North
Edwards Boulevard, Lake Geneva, Wisconsin.

       Best  Buy Stores, L.P., a wholly owned subsidiary of  Best
Buy,   Inc.  ("BBY"),  owns  the  fixed  assets,  inventory   and
receivables  associated with BBY stores  located  in  the  United
States.  As  the  parent  company of the  tenant,  BBY  does  not
guarantee  the  lease  and  is  not  responsible  for  any  lease
obligations. BBY, headquartered near Minneapolis, sells  consumer
electronics,   home-office  products,   entertainment   software,
appliances  and related services through more than  1,200  retail
stores across the United States, throughout Canada, and in China.
For  the fiscal year ended March 1, 2008, Best Buy reported a net
worth  of  approximately $4.5 billion, revenue  of  approximately
$40.0 billion and net income of approximately $1.4 billion.  Best
Buy  is  a  public company whose stock is traded on the New  York
Stock  Exchange under the symbol BBY and files reports  with  the
SEC   that   are  available  on-line  at  the  SEC's   web   site
(www.sec.gov).

Section 9 - Financial Statements and Exhibits

Item 9.01 Financial Statements and Exhibits.

      (a) Financial statements of businesses acquired  -  Because
          the  property is leased to a single tenant on  a  long-
          term   basis   under   a  net  lease   that   transfers
          substantially all of the operating costs to the tenant,
          we  believe that financial information about the tenant
          is  more  relevant  than financial  statements  of  the
          property.  Financial  information  of  the  tenant   is
          presented in the last paragraph of Item 2.01.

      (b) Pro forma  financial information - A limited number  of
          pro  forma  adjustments are required to illustrate  the
          effects  of  the  above transaction  on  the  Company's
          balance  sheet  and  income statement.   The  following
          narrative description is furnished in lieu of  the  pro
          forma statements:

          Assuming the Company had acquired the property on  June
          5,  2008  (date the Company commenced operations  after
          accepting the required minimum subscription proceeds of
          $1,500,000), the Company's Investments in  Real  Estate
          would  have  increased by $1,991,220  and  its  Current
          Assets (cash) would have decreased by $1,991,220.

          Rental Income for the Company would have increased from
          $37,681  to $48,104 for the period ended June 30,  2008
          if  the  Company  had  owned the  property  during  the
          period.

          Depreciation Expense would have increased by $2,945 for
          the period ended June 30, 2008.

          The  net  effect  of  these pro forma adjustments would
          have  caused  Net  Loss  to decrease  from  $11,367  to
          $3,889, which would have resulted in Net Income per LLC
          Unit outstanding of $0.05 for the period ended June 30,
          2008.

      (c) Shell company transactions - Not Applicable.

      (d) Exhibits.

          Exhibit 10.1  - Assignment and Assumption  of  Purchase
          and  Sale  Agreement dated August 7, 2008  between  the
          Company,   AEI  Income  &  Growth  Fund  XXII   Limited
          Partnership, AEI Income & Growth Fund 24  LLC  and  AEI
          Fund  Management, Inc. relating to the Property at  700
          North Edwards Boulevard, Lake Geneva, Wisconsin.

          Exhibit 10.2 - Assignment and Assumption of Lease dated
          October  6,  2008  between the Company,  AEI  Income  &
          Growth  Fund  XXII Limited Partnership,  AEI  Income  &
          Growth Fund 24 LLC and Ryan Companies US, Inc. relating
          to  the  Property at 700 North Edwards Boulevard,  Lake
          Geneva, Wisconsin.
