It's quite risky even without news like that. Once you allow someone into your house you have a problem. Large companies who speciaize in rental property can deal with this - in part by having maintenance people on site, in part by purchasing insurance, and in part by just offsetting the losses by profits from other properties. It also helps to have a few lawyers on retainer, have a convenient rental contract, and know all your rights. A lone homeowner has none of that, and a bad renter can do pretty much whatever he wants, for a long time.
Many home insurance policies exclude business from being conducted from the house.
Thanks for that injection of Econ 101. Sad that people don’t know and don’t care!
