Seller financing deal

[MarieChele Porter]

Hi everyone!

Ok so my realtor just sent me over a deal that I am interested in that offers seller financing but I have no idea where to start! It's an 8 unit property in the central valley of California (Fresno) and rents are below market at about 4 units at $550 and 4 at $650 when they could be up to 700-750. The property is listed at 650k but he suggests trying to go in at 600k with 10% down and 7% interest only for 3 years. Of course there are different scenarios I can try as well to tailor it to what the owner may like but looking for ideas from people with experience on these kinds of deals. 

Any suggestions, ideas or feedback is greatly appreciated!

Thank you, MarieChele
