Landmark at Grand Palms

On October 31, 2012, the Company, through its Operating Partnership and pursuant to an Interest Contribution Agreement by and among the LATA Parties, Elco Landmark Residential Management, LLC, Elco Landmark Grand Palms Management, LLC, Legacy at Grand Palms LLC and Grand Palms Investor, LLC, acquired 100% of the membership interests in Landmark at Grand Palms Holdings, LLC, a Delaware limited liability company that owns Landmark at Grand Palms, LLC, which in turn owns as its sole asset one of the Contributed Properties (the “Landmark at Grand Palms Property”), in exchange for consideration valued at approximately $40,000,000 (subject to prorations and adjustments), including 2,341,841 Common Units valued at $8.15 per unit representing aggregate consideration of approximately $19,086,011 and the assumption of $20,951,384 of mortgage indebtedness. The Landmark at Grand Palms Property is an apartment community located in Tampa, Florida, comprised of approximately 369,362 rentable square feet and containing 438 units. As of October 31, 2012, the Landmark at Grand Palms Property was 96.4% occupied.

The Company assumed an aggregate of $20,951,384 in mortgage indebtedness in connection with the acquisition of the Landmark at Grand Palms Property, pursuant to two separate mortgages. The first, in the assumed principal amount of $18,581,501, has a fixed interest rate of 5.94% and matures on September 1, 2019. The second, in the assumed principal amount of $2,369,883, has a fixed interest rate of 6.58% and matures on September 1, 2019. Both loans are held by Fannie Mae and serviced by M&T Realty Capital Corporation.
