Im interested in doing short term seller financing as the buyer, on a five unit commercial/residential building. The seller is also interested in being creative. Is there a best way to structure this deal? when the seller has a current commercial loan in place? I dont need seller to finance for very long, I just need some time to finish up stabilizing a current MF project I have going. Do you  think his bank would be open to me assuming his loan? Its a local bank and the balance is small, were talking about only a few hundred thousand purchase price for me.

@Matthew Wright   I also have a 5 unit commercial / residential building and loan.  I had to provide a personal guarantee and they looked at my personal financials (in addition to the rent roll, etc).  

I believe you would have to reach out to the bank and formally apply and be approved for assuming the loan, if they allow that at all.  Being a local bank, they probably have more flexibility as they're prob holding the loan in-house.  But I definitely wouldn't try a seller finance / transfer of title without letting them know.
