It happens to be very easy to vacate a building if, like so many landlords, you don’t mind being a bad guy. When these landlords buy buildings they intend to vacate, they use corporate names that are difficult to trace. Then they hire thugs to come in with sledgehammers and smash up the boiler, rip out the stairways, and create floods by cutting holes in pipes. They import truckloads of junkies, prostitutes, and thieves and move them into vacant apartments to terrorize holdout tenants.
