Hartman XX Declares $12.40 NAV per Share

On April 11, 2016, Hartman Short Term Income Properties XX, Inc. (“Hartman XX”, “the Company”) announced that its board of directors approved an estimated net asset value (“NAV”) of $12.40 per share of its common stock. This is the first time that the board has determined an estimated per-share NAV for the Company.

Hartman Advisors, LLC, Hartman XX’s advisor, engaged WKW Advisors, an independent third-party real estate advisory firm, to assist in determining the estimated per share NAV and a fair value range of Hartman XX’s real estate portfolio holdings.

WKW Advisors’ valuation was based upon the estimated market value of Hartman XX’s assets, less the estimated market value of the Company's liabilities, divided by the total shares outstanding, and was performed in accordance with the valuation guidelines established by the Investment Program Association Practice Guideline 2013-01, Valuations of Publicly Registered Non-Listed REITs. WKW Advisors’ per share valuation reflected a range of $11.93 - $12.87.

The sale of shares of our common stock to our stockholders pursuant to our distribution reinvestment plan (“DRP”) will continue until as late as July 13, 2016. Beginning in May, 2016, DRP shares will be sold at NAV of $12.40 per common share.

Hartman XX commenced its initial public offering in February 2010 for up to 250,000,000 shares of common stock at a price of $10.00 per share.  On July 16, 2013, the Company commenced its follow-on public offering, or our “follow-on offering,” of up to $200,000,000 in shares of our common stock to the public at a price of $10.00 per share and up to $19,000,000 in shares of our common stock to our stockholders pursuant to our distribution reinvestment plan at a price of $9.50 per share.   The program closed to new investments on March 31, 2016.

As of December 31, 2015, Hartman XX owned 15 properties and had accepted subscriptions for and issued 14,038,203 shares of our common stock in our initial public offering and follow-on offering, including
