This is where a property manager proves their value. They screen tenants, check references, credit scores, do background checks. They write up a lease agreement that says is a tenant is storing garbage on the property or becomes a nuisance to neighbors, that's grounds for eviction. They will collect the evidence and take it to court.

If you have a good renter, who pays on time and doesn't cause problems, VALUE them, and don't raise the rent every opportunity you get, just to maximize profit.
