Purchasing Sub-to Seller Finance Contract?

[Paul Crutcher]

Hi everyone!

I'm currently looking at a home that was previously on the MLS and failed to close via conventional financing 4x due to deferred maintenance and stubborn sellers possibly.

So going to a bank for financing isn't an option for this home. 

The home currently has a ~$160k seller finance mortgage that the current seller is paying (not sure if they're performing). They did want $60k over the mortgage amount, however I believe it's only worth $20k over. 

So I was thinking of offering to take over paying the note and basically giving the seller a cash sum for the rights to the contract/deed. I haven't heard from the seller yet if I can get a copy of the original contract.

How would I go about this? What attorneys would y'all recommend to help me through this process?
