Based on observation of my family home i expect decent tenants to cause some damage inside a home. I can be pretty flexible about this without much harm coming of it. I hope they are happy and pay the rent while they are at it. Then when they are ready to leave you get it ready for the next people. I don’t anything wrong with this process when it is not extreme. I don’t think pets make it extreme..or that excluding them changes risk much. What it does potentially change is how long they live there. With all the pet condemners out there they may be prone to sticking around for a while. Real concern with pets would be causing problems for neighbors with barking or other things.
