purchasing a quad plex

[Jonathan Polanski]

So I'm in the process of purchasing a quadplex in South Florida, I put in an offer 5k more than asking because buyers are really aggressive here I lost out on a few good deals here to other investors so I wanted to get aggressive, and I'll make 17% cash on cash ROI with all my expenses allocated even at 5k more than asking. So my offer was sitting around for a week and a half, we (my realtor) had to hound the owner down. We finally got in contact with the owner.

He suggested that we do seller finance with 100k down. I thought this was a terrible counter offer, I have financing, I don't desperately need financing. I was going in 20% down which would have been 50k with hard money, then convert it to conventional @ about 5.8%. So now that he has me in seller financing how can I finesse this deal?

quad is going for 250,000
