The pace of retail property sales activity has picked up this year. The $200.6 million exchanged in 36 transactions through the first two quarters amounted to 58.8% of the total amassed in all of 2011. The total for the latest quarter alone was $105.4 million for 17 trades, at an average selling price and mean cap rate of $118 psf and 7.1%. The 12-month rolling cap rate per quarter-end was 6.8%, down from 7.9% a year earlier. In the quarter’s largest sale and the largest in a year that meets Reis’ criteria, Blackstone paid DDR $22.9 million ($87 psf) in June for the 263,594-square-foot Lake Walden Square property in Plant City.
