Homes prices are up on Long Island for the first time in more than two years, the Multiple Listing Service of Long Island said in its January report, which also covers Queens. Median closing prices for the month rose to $365,000, up 4.3 percent over the $350,000 median price registered in January 2009. One month does not a trend make, though, and MLS Long Island President Frank Dell’Accio predicted that prices will go back and forth for the next few months. “At a minimum… we can start to look at it and say there’s a possibility that prices have stopped declining,” he said. Activity was also up during January, while inventory was down. More than 2,000 closings occurred, up 25 percent over a year ago, and MLS Long Island’s listings were down 14 percent to 33,417 homes.
