I'd spoken with the owner briefly on the phone once before and we'd discussed the overall condition of the property, why he wants to sell, how much $ he'd be happy to walk away with, etc.After the screening questions over the phone I threw a number out and he said it'd be the lowest he'd accept and still be happy with, but he'd still need to speak with his wife about it.Anyway...so today I met with them in person and he gave me some more info.This property is zoned for R-4.

Build a relationship with them. 2) An agent could work as a designated agent (solely representing you),  dual agent(I would NOT do that), or transaction broker(they represent the transaction but give NO advice)3) No difference between the process.4) Financing is the same just walk it before offering.
