The first half of 2015 saw record-setting apartment sales, as one-off transactions drove the market. Not surprisingly, New York and Los Angeles saw the most transaction volume in the first six months of the year (New York was tallied as two separate counts: Manhattan as one and the other four boroughs as the other), according to Real Capital Analytics.

But venture further down the list and you’ll see a lot of activity in high-growth (and sometimes-volatile) Sun Belt markets. You’ll also discover the one city that saw its transaction volume decrease in the past year. Here’s the list:
