How to make the best of this? Potential DEAL!

[Zac P.]

I have a buddy that unfortunately is losing his house to foreclosure. I am a bit confused (I think he is too), he owns it in full (no mortgage).. He did "rent to own" which ended badly and I believe the foreclose will someone clear the title (he says the past tenant still has rights to the property, but is long gone). He says he believe he will have the option to buy the property back after the foreclosure for next to nothing. I asked him if he would just sell it to me and he said is ok with that, but the title has issues. He also said he would be open to seller financing. This is a very motivated, out of state owner. This could potentially be a great deal, but I am unsure on how to proceed with this... If you guys were in this situation, how would try to cash in on this? I am a newbie as well as this seller. Please bare with me. :)
