Buying House From Private Seller w/ No Money

[Matthew T.]

I ran across this seller that wants to sell his home for $100,000 and the home is worth around $150,000. The homes in the area are selling around $130,000 on up. He's interested in cash but currently I don't have that kind of cash to obtain his house. Is there anyway I could buy his home maybe with a loan or something of that type. My credit score is in the 500s by the way. How can I work out and structure a deal with this person? Please if you can give me any strategies and tips. Any information would be greatly appreciated. Thanks!
