These type of loans are enticing. I have not done them – the 2 places I have bought in the past 2+ years I did 10% down and try to get it below 80% ASAP. My business is risky enough that I don't want to risk it. For the folks that go for it on interest only, I say go for it. But beware, one day you may need to pay the piper. No one knows for sure.
