MLS-listed occupied rental property ... pitfalls? DD?...

[George P.]

Saw a (newly listed and attractively priced) rental property with tenant whose lease expires 4 1/2 months from now. The current owners live in another state, 10 hours away. Property has been owned by this couple since 1994 - most likely paid off, but I can easily confirm that if needed. (I didn't go out to see the property, only checked some info).

I am not sure what the situation is, and MLS remarks suggest that "great tenant is wanting to stay".
I assume - but please correct me if I'm wrong - that after the contract is accepted, prospective buyer can lawfully ask to provide the payment history, copy of lease and recent Schedule E for buyer's DD and verification. I assume the inserted contact clause "subject to buyer's satisfactory review of the documentation" will allow to void contract should the discrepancies be found?

Being very conservative and suspicious, I assume the worst case scenario: poorly-paying and/or non-cooperating tenant (hence listing an occupied property). I'd want the tenants leave regardless, cause I'd like to find my own. But I guess I should calculate the worst case scenario with eviction costs and no payments for several months?

**** What else I should be concerned about? Please chime in.
Thanks !! ***
