Need advise on structuring a seller financing deal

[Marcelo Ricarte]

Hello BP Family, my wife and I got a possible deal financed by the seller. We have no knowledge on how to structure a deal like this so we need your help!

Some info: Seller is getting rid of some properties and we want to acquire two of them.

Asking price $245k each. Two duplexes. Roofs 10 years old. Overall they look decent from outside (maintained) in a B- area. Tomorrow we'll do a walk through to see the inside.

Is there a standard approach in this cases?

Any advise will be greatly appreciated.
