Metro area home sales fell 27 percent in May, according to figures compiled by the Greater Baton Rouge Association of Realtors.

Realtors sold 580 homes in May compared with 790 that month the year before, and dollar volume fell 25 percent to $114.0 million.

As they have for about a year, home sales fell in all three of the metro area’s major parishes.

Baton Rouge’s real estate market hasn’t suffered ill effects of the bursting of the housing bubble the way other markets have. But real estate agents have said low interest rates haven’t been enough to counter stagnant job growth, shaky consumer confidence and a market largely tapped out after a federal tax credit created a spurt of first-time homebuyers last year.

For the year, Realtors have sold 2,439 homes, 16 percent fewer than the 2,918 sold through the first five months of 2010. Dollar volume for this period is down 17 percent to $466.6 million.

The year-ago numbers represent the last few months of the tax credit program, which offered qualified first-time homebuyers up to $8,000 in tax credits and boosted sales of homes on the lower end of the market. The gap will likely narrow somewhat by late summer as the figures are compared to sales unaffected by the program.

Homes are staying on the market much longer. Current days on market for May was 147 days, compared with just 106 a year earlier. The metro area had 4,897 houses on the market at the end of May. That’s 8.4 months of inventory compared with 5.8 months a year ago.
