Inherited Tenants

[Adam Shindler]

Hello BP Community,

It appears as if I will be inheriting tenants in one unit of a duplex I am purchasing.  

Here is my questions:

The current tenants are smokers, the unit reeks of smoke, and I can't imagine the damage that has been done to the place over their 7 year tenancy.  My policy for rental screening is "no smokers allowed", however I understand that these tenants pay on time and are nice, quiet people.

Because I suppose the damage is already done, should I just let them stay and go through the necessary rehab when they vacate eventually?
