Renting one room in my house to a medical professional. Put in two brand new bathrooms last year and so far there is melted red wax on the tiles, and hair dye stains on a cream wool carpet. More than normal wear and tear? They may stay for a couple of years, and they are nice, pay on time. Just can't get why people are so careless. We rented an air bnb 2 weekends ago and left it spotless. Living room has loads of their stuff including furniture in it. Do i charge for carpet down the line? Up the deposit? Two of their family members will stay for a few months later this quarter, I'm charging a modest amount. House is insured for lodgers. Comments welcome, haven't rented rooms in years. THX
