A property deal that seems sweet... how to fund?

[Frank Curtis]

I've been watching Loopnet and I came across a person selling 3 properties at once. I have looked at some of the data and it seems like it could generate some decent income. How would I go about financing this, could I get a loan from a bank if I lived in one of the duplexes? Should I ask if the seller could carry the loan? I talked to a hard money lender the other day and they only give out loans when someone's rehabbing a single family. Should I lock it up with a 3 month contingency to shop around for funding? Any help would be greatly appreciated, I'm in the OKC area.
