First commercial offer. Need opinion.

[Jack Middleton]

I have decided to make an offer on a 5-Plex. Since I have never delt with commercial properties I am not sure how to structure the deal, or if it would be acceptable for the seller to help me with the down payment. I would like him to pay 60%, possibly in the form of a loan. Is there any preferred method of doing that or do we have that written up in the offer for a second for $xxx over 12 months at x% interest. And if so, will lenders be ok with that?
