I have a hard time believing that. Let me count the reasons why:
1) It's a big number on a sign stapled to a utility pole.
2) We're in Queens Village, a neighborhood of modest homes, about a 7-mile drive away from where the US Open is played in Flushing Meadows. There are enough fancier areas located closer to the tennis center to satisfy whatever minimal demand there may be among the super-rich for $10,000/day housing options that are not in Manhattan.
3) This sign was put up by, or is at least almost identical to signs previously put up by, a company called Major Event Rentalz. With a name like that, I'm automatically suspicious, unless they're cutting my hair.
4) Major Event Rentalz is one of a number of similar companies (including the purportedly unrelated Major Event Rentals) that promise you big bucks for renting out your home, but make you pay a hefty sum up front for listing your place. If that sounds shady to you, you probably won't be surprised to learn that the State of Indiana sued Major Event Rentalz and another company in 2012 for ripping people off in the lead-up to that year's Super Bowl in Indianapolis by charging them high fees and never finding them renters.
