(Wall Street Journal) — A few years ago, sales in new condominiums in Brooklyn stalled, and many projects came off the market. But a revival in sales in new condominiums, especially in more expensive units, has sparked new life in the Brooklyn market, driving sales prices higher in the first quarter of 2011, according to new market reports released on Friday. Demand for more expensive townhouses in prime locations, was also strong, brokers said. “Absorption in new development has been incredible,” said Frank Percesepe, who overseas Brooklyn sales for the Corcoran Group. “My fear going forward is that we are not going to have the inventory we had before.” Still some analysts were more cautious.Jonathan Miller, an appraiser and president of Miller Samuel Inc., said that though sales rebounded during the first quarter, the sales pace and prices have been moving up and down from quarter to quarter in a narrow range.
