90% LTV 10% owner financing

Trying to put this deal together. Everything is looking good. Seller is motivated and should accept the owner financing. So typically, what type of terms would you want on the 10% owner financing? I was thinking something similar to the 90% terms and rates only make it for 1 or 2 years with 30 yr amortization. Does that sound right? And in order to pay the seller at the end of the term, I would just refinance the full amount? Is that possible?


Are interest only payments smart on the 10% owner financing?
