The brokers say the market for homes listed under $5 million is poised for higher prices, with steady or better sales volume as demand appears robust and the supply of homes for sale is low.
Traditionally the high level of wealth among the buyers of homes in these beach communities makes it somewhat protected from market gyrations, though not fully.
"There are two markets right now," said DeVivio. "On the low end it's clearly still a seller's market, and on the high end it's clearly a buyer's market."
Ernest Cervi, regional senior vice president at Corcoran in Bridgehampton, said the median sale price was up every quarter last year while the inventory of homes for sale was in decline.
"Our inventory has been decreasing since 2011, so I think the market is in a good place right now," Cervi said.
