The Long Island Board of Realtors hosts its seventh annual Open House Weekend this Saturday and Sunday.

Real estate agent Matt Arnold says there are more than 3,000 open houses scheduled for April 9 and 10 in Nassau, Suffolk and Queens, with more than 250 real estate offices participating.

Arnold works for Netter Real Estate in West Islip, and after more than two decades in the real estate business, he says there’s no doubt the current market is “on fire,” with some sellers fielding multiple offers and dealing with bidding wars from cash buyers. Arnold says he’s expecting a great turnout as open houses provide a low pressure way for buyers to look around and find what they need.

The weekend is scheduled to coincide with the beginning of the peak time for home sales, between April and July, when there are more houses on the market and more people looking to buy. There’s a $1,000 sweepstakes for visitors.

Advice for the sellers before Open House Weekend? Declutter, Arnold says, as buyers are looking for openness and light. And wash those windows so you don’t have the remnants of winter getting in the way of welcoming everything the hot spring housing market has to offer.
