Bad Leases and Tenants

[Chaz Sztroin]

I'm actively looking at a duplex near Pittsburgh, PA where the numbers make sense and the option for forced appreciation exists. It's a great location near the hospital and in a thriving community. 

The issue is the existing landlord has no rent rolls available and no active leases in place. The duplex is fully rented but each side is month to month. Upon inspection of the property one side has been taken care of, the other side has not. I get the feeling rents are not coming in and this is the reason for the sale. 

Has anyone dealt with a situation like this? This is my first deal so I'm trying to gain more perspective from someone who's dealt with a similar situation.
