A Seller involved with a Bankruptcy/Forclosure Defense Attorney. Possibility??

[Robert Lolofie]

I live in my parents rental in OK which was my childhood home(Class C Area). 2 doors down is family friend who hasn't managed his life too well ie financial, marital, spiritual, and health problems.

I talked to him today and he is going to be put out on the street in a couple months because he can't keep his home.

He wants to sell to me or my dad because we've gained favor with him. 

!!!Here is the problem. He said that he "can't go into foreclosure because of the modification that the attorney set up". Don't think I have all the info I need. 

If this attorney has made payments to his mortgage for him, do I have to talk to the attorney about buying his house because of the attorney's vested interest?

Anyone have any thoughts or experience they could share with me?

Thanks in advance!
