Like someone else, we have a house that we rented to tenants who started out great and got progressively worse over the second year we rented to them. Like...we stopped by and their mother was living with them, and a baby she had just adopted, and two dogs (not allowed). And a boyfriend. All not on the lease, no notification, nothing. Things would break and they wouldn't tell us, and so on.
When they left we had to put about 3 days of hard work into cleaning the place, and hire floors, painting, etc.
Our solution, since we live 3-4 hours away, was to get a really good property manager. Bliss. Actually, local laws require us to have one given how far away we live - I did not realize this when we first decided to rent the house. We were not realistic about what it takes to be a property manager, and now that we know it's not a job we want. Fortunately the town has a great price-to-rent ratio, so its fine, and the rent covers all the expenses (good old 50% rule) and twice the mortgage.
The immediately raised the rent, found great tenants, and we have had no issues and no vacancy.
Difficult tenants can be very, very, stressful if you don't know what to do and you are far away. You may want to find an experienced buddy you can call.
