Note the story of 79-year-old, fish-loving Richard Lester. Back in ’56, he bought a tiny slice of the posh Hamptons’ Amagansett South – roughly a third of an acre – for a sweet $300. On it, he stuck a small, one-bedroom trailer that set him back $15,000. Well, fast forward to now, and guess what? That patch is rocking a cool $1.1 million price tag, thanks to its enviable spot. It’s merely a mile from Indian Wells Beach and a shout away from stars like Jerry Seinfeld and Paul McCartney. Douglas Elliman Real Estate thinks someone could build a handsome 4,000-square-foot house and a pool on the site. Richard? He is just gob-smacked at what his humble lot has turned into, pointing at the Hamptons’ magnetism for deep-pocketed folks.
