Cass Almendral has been having himself a great summer — and he owes it all to his house. Half a mile from the Southampton train station, his eight-bedroom, $4 million 1890s farmhouse, complete with a pool and hot tub, has been the site of many a summer bash. But it’s done more than just serve as a party castle. It’s given Almendral his cachet with the ladies. “If you own a house, you’re at a huge advantage,” he says. “That’s why I’m single. Every summer I can have a huge adventure.” “I’ve had girls who’d take the bus over and linger around, then have sex with anyone who had a house,” says Almendral, the 50-year-old managing director of the Wall Street Solutions Group Inc. “They weren’t hookers. They got by through the kindness of strangers . . . they see the Hamptons as an adventure that’s also a safe, luxurious experience.”…Newbies on the city scene are quickly initiated into the game. “Some girls will pressure girls who are new to the city to be friends with a certain guy because of his Hamptons house,” says a 25-year-old woman who works at an investment banking firm. “It’s an overarching theme of the summer — find a guy with a home and date him.” [NYP]
