Remarkably, the $92.2 million accumulated in four apartment property sales during the second quarter amount to the largest single-quarter total on Reis’ records for this market, which begin in first quarter 2005. The latest quarter’s total, moreover, virtually doubles the total recorded for all of 2011. The average selling price and mean cap rate for the quarter’s transactions were $81,000 per unit and 4.8%. The 12-month rolling mean cap rate per quarter-end was 5.8%, up from 4.7% a year earlier. In the quarter’s largest deal, second-largest in a year, Somerset Partners LLC paid DRA Advisors LLC $28.5 million ($83,333 per unit) for the 342-unit Barrington on the Green market-rate property in Hoover. The sale closed in April at a 4.9% cap rate. The Class A property was built in 1996.
