Completed Acquisition

Avondale by the Lakes Apartments

On July 25, 2013, the Company, through its Operating Partnership, acquired 100% of the membership interests in Solera Partners DE, LLC, which owns as its sole asset a multifamily residential apartment project in St. Petersburg, Florida, known as Avondale by the Lakes (the “Avondale Property”), in exchange for aggregate consideration valued at approximately $18,445,755 (subject to prorations and adjustments), including (i) 67,463 common limited partnership units in the Operating Partnership valued at $8.15 per unit representing aggregate consideration of approximately $549,824 (subject to adjustment based on prorations); (ii) approximately $6,287,279 paid in cash; and (iii) the assumption of existing mortgage indebtedness in the amount of approximately $11,971,452 as of the date of the closing. In connection with the acquisition, the Company entered into an Interest Contribution Agreement with Elco Landmark Residential Holdings, LLC and one of its affiliates, a copy of which is attached to this Current Report on Form 8-K as Exhibit 10.1 and is incorporated herein by reference. The Avondale Property is an apartment community located in St. Petersburg, Florida, comprised of approximately 315,450 rentable square feet containing 304 units. As of July 25, 2013, the Avondale Property was 92% occupied.

The mortgage indebtedness assumed in connection with the acquisition of the Avondale Property is a fixed rate loan currently held in a CMBS pool and serviced by KeyBank, National Association, as master servicer. The loan matures on November 1, 2020 and has an interest rate equal to 4.59%.

In evaluating the acquisition of the Avondale Property and determining the appropriate amount of consideration to be paid, the Company considered a variety of factors, including property condition reports, tenant rent rolls, property location, visibility and access, age of the property, physical condition and curb appeal, review of an independent third-party appraisal, neighboring property uses, local market conditions, including vacancy rates, area demographics, including average household income, neighborhood growth patterns and economic conditions, and the presence of demand generators.

The information set forth under Item 2.01 of this Current Report on Form 8-K is hereby incorporated by reference into this Item 2.03.

The information set forth under Item 2.01 of this Current Report on Form 8-K regarding the unregistered issuance by the Operating Partnership of common limited partnership units is incorporated by reference herein. The Common Units have the rights and preference as set forth in the partnership agreement of the Operating Partnership and will, following a 12-month holding period, become redeemable in exchange for either shares of common stock of the Company on a one-for-one basis or cash. The limited partnership units were issued in one or more private placements pursuant to Section 4(2) of the Securities Act of 1933, as amended.

As reported in the July Form 8-K, the limited partnership units that were issued by the Operating Partnership in connection with the acquisition of the Contributed Properties were subject to prorations related to standard and customary prorated amounts. Accordingly, in connection with the completion of the acquisition of the Avondale Property, the limited partnership units previously issued for the Contributed Properties were reallocated amongst certain of the contributors of the properties. The revised agreements reflecting the reallocations are included herewith and supersede the applicable agreements filed with the July Form 8-K.
