Looking for a place to stay? Public-housing residents are renting rooms to strangers. They are making extra money over the holidays while taxpayers fund their apartments. Several ads for nightly or monthly sublets were posted on Craigslist last week. One of them was including a $650 room in Brooklyn’s Sheepshead Bay Houses. The ad claimed, “Huge room available immediately in a 3-bedroom apartment for rent,” the ad says. “Females only . . . no drugs, no smoking, no drama.” The tenant of the room listed a cellphone number and a New York City Housing Authority address. They declared that two people could also share the room for $350 each. That’s an extra $7,800 a year in the pocket of someone who is living on the public dime. Horrible!
