@Mike HaworthIn situations like this, I also skip-trace the residents on either side of the target property.Those close neighbors can be a goldmine of info on resident history, any recent comings and goings, and last known contact info. 

It's probably best to start by reading up on some books on the subject as well as networking with others here who have done these types of deals already.

Understand the tax implications of divesting from the properties as well as taking on seller financing.
