Here's some helpful info:A bad tenant can lead to thousands of dollars of losses via unpaid rents, legal fees and property damages.

The Tenant Classgreatly impacts rental income stability and property maintenance/damage by tenants.Both Property Classand Tenant Class affect what type of contractors, handymen and property management companies will work on a property.If you buy & renovate a property in Class D area to Class A standards, what Tenant Class will rent it?

Quote from @Theresa Harris: He should have a portable AC unit in his bedroom, but if they (the tenant) are causing damages/excessive wear and tear, do not renew their lease.
