Seller Financed Multi Property Deal

[Jason Durst]

Hello all! I'm not sure if I'm in the proper forum.... but here goes. I was casually offered by an acquaintance the opportunity to purchase several single family homes and a duplex all at once. My potential seller is getting to be a bit older and wants to retire. I'm just starting and have very little capital to play with at this point. The seller offered to finance the deal. Other than doing my due diligence and reviewing the last several years of financials, what else should I ask of him? Also, more importantly, is there an industry standard or a fair percentage I should expect him to ask for on the money. I'm also thinking that I may be able to go with no money down as he seems motivated to just wash his hands of the work involved. Thoughts, advice.... Thanks in advance!
