Inherited tenants with junk cars and trash

[Chris Chartrand]

Hello BP, I am considering purchasing a property with two, two bedroom apartments and two mobile home pads. The property is in rough shape with tenants having trash and junk cars strewn about. When we looked at the apartments, they were in rough shape, dirty, and run down. The mobile homes are owned by the tenants and the lots are rented. My question is, can I introduce covenants to the property for trash, cars, etc. with inherited tenants. 

Also, fyi I have a 3/2 rental across the street from this property, the property in question is 8.9 acres, so room for growth. My goal is to turn this into a nice rental community. I just don't want to jump into this if I can't get the current tenants to clean up.  Any thoughts would be appreciated.
