Buyers snatched up 14 single-family homes during the month and three condominium units, according to the Warren Group, which tracks housing data statewide.
Those figures were down from January 2011, when 21 homes and four condos sold.

While sales were down, the median price for single-family homes increased 11.75 percent to $352,000. Condo prices increased 16.5 percent to $180,000.
Statewide, home sales increased on lower prices that drew buyers into the market, said Warren Group CEO Timothy Warren.
"After a decline in sales volume in December, it's promising to see the highest sales volume in five years in January," Warren said. "Given low mortgage rates and steady prices, there's hope this year may fare a bit better."
