I am renting out our house and tenants living there 3 months. When they were moving in the dad said he might paint one of bedrooms for his son. I said fine. Now I get text saying he has painted whole house at 130e. Before I rented it out I had painted kitchen, hall, landing and utility and bathroom. Now he hasn't asked for money but not sure I am to offer. I'm sure he will ask. I am far from loaded and had to move as a necessity. And at the moment having cashflow problems. Who should pay
