As for buy and hold, you’ll buy at a discount and the concern will be the quality/completeness of the remediation, which is almost impossible to verify..

I haven’t done my own due diligence to look deeper into this, and verify for myself (so maybe somebody else can shed some light?)

@Mike AllisonDuring the due diligence I should have pushed harder to verify security deposits and rents with an addendum signed by tenants.

(usually verified by the appraiser, particularly for FHA & VA).Will the buyer's lender allow the assignment of contract?

The court is of little help in such situations since if tenant does not provide forwarding address, the court will not process a complaint. as a Landlord i am desperately searching for a way or a method outside of traditional credit bureaus to verify and screen such tenants.

It has failed once when a tenant failed to put the key back and locked themselves out before we were over to have verified the key was present and to change the combo. 

I use Icomps and then i verify on the assessors website to see if they did sale for that amount. 

With an OOS situation and large rehab being done by the people that are also verifying the work can be problematic to say the least

Trust, but verify.

Call the day you sign the lease to verify that has been done.
