Not using a realtor, how can I find comps to see if seller financed deals are good?

[Amy Solomon]

Hey everyone! I will have tons more questions coming regarding getting things off the ground. I am looking towards several forms of financing. One includes something I haven't seen talked about on these boards. Which is a seller financed flipped.

My goal is to offer a seller who may not be able to sell to a buyer with a conventional loan (or perhaps just hasn't been able to sell due to home's condition) a 6-9% interest rate, 0 points, 5% down, interest only payments with a balloon in 12 months.

MY question is, I won't be using a realtor to help me find these deals...(i think) so how can I find the true arv? I need to see comps on other homes, realtors.com doesn't allow me to do this (from what I know). What's your advice on how to thoroughly research, find comps and get a good arv so I can know if it's a good deal?

Thanks for your help!
