It’s not easy to rent. People renting resent any increases in rent and always try to manipulate keeping their rent down. Also when they do leave they often leave a mess where everything needs to be updated and painted.

You really have to keep rentals a business relationship. You are learning one of those hard life lessons. My daughter has rented and learned her fair share of lessons. Renting isn’t for everyone.

From what you describe this rental has too many hazards and needs updating which means spending money. You have a right to charge rent with currant rental rates especially with your rental being in such a desirable location.
