Item 2. Properties.

We seek to acquire newer apartment communities and those with opportunities for repositioning through capital additions and management improvement located in the Southeast, Southwest and Mid-Atlantic regions of the United States with the potential for above average growth and return on investment. Approximately 69% of our apartment units are located in the Florida, Georgia, North Carolina, and Texas markets. Our strategic focus is to provide our residents high quality apartment units in attractive community settings, characterized by upscale amenities, extensive landscaping and attention to aesthetic detail.

The following table summarizes our apartment community portfolio and occupancy levels by location, as of December 31, 2019:

Thirty-two of our multifamily apartment communities reflected in the above table also include commercial components totaling approximately 630,000 square feet of gross leasable space. We also owned four commercial properties totaling approximately 260,000 square feet of combined gross leasable space as of December 31, 2019. See “Management's Discussion and Analysis of Financial Condition and Results of Operations” for a discussion of our Same Store and Non-Same Store and Other portfolios.
