$383,000  cash.     The  source  of  the  cash  used  to  acquire  the  additional  interest  in  the  Joint  Venture  was  proceeds

from  the  current  public  offering  of  the  Company’s  common  shares.   Following  the  transaction  the  Company  owns

31% and Hartman XIX owns  69% of the Joint Venture.

   Hartman  Short  Term Income  Properties  XIX,  Inc.  (“Hartman  XIX”)  is  a  REIT  that  is  managed  by affiliates  of  the

Company’s advisor and real property manager.

On  December  28,  2010  the  Joint  Venture  acquired  the  Richardson  Heights  property  for  $19,150,000.    The

Company  initially  acquired  a  10%  interest  in  the  Joint  Venture  for  $1,915,000  cash.    On  April  20,  2011  the

   On  April  19,  2011  the  Board  of  Directors  of  Hartman  Short  Term  Income  Properties  XX,  Inc.  (the  “Company”)

authorized  the  Company’s  officers  to  consider  a  series  of  related  transactions  to  acquire  up  to  all  of  the  limited

liability  company  interest  of  Hartman  XIX  in  the  Joint  Venture.    The  Company  is  not  obligated  to  acquire  any

specific  portion of the  Hartman XIX  joint venture  interest.   Each prospective  acquisition is subject to  management’s

discretion and the Company’s financial position and liquidity.

For  purposes  of  determining  the  value  of  the  transaction  between  the  parties,  the  respective  Boards  of  Directors  of

the  Company  and  Hartman  XIX  determined  that  the  acquisition  price  for  the  property  is  the  fair  value  of  the

property and the total value of the limited liability company.
