Quit Claim Deed... How does that work?

[Teowonna Clifton]

So... I've found a deal that is very interesting to me. If it goes through, this would be my first deal. But I need your help with a few questions. So... this seller needs to sell his property quickly. He is a couple of months behind on his duplex mortgage (about 3k) and wants to sell it via quit claim before it forecloses. The buyer will pay the outstanding amount and a little cash to him. The property does cash flow. So, here is my question... how does the quit claim deed work with the existing mortgages (there is a first and second, totaling $118k)? Would his name remain on the mortgages? Will the note be accelerated and require payment in full? What are the questions I need to ask? What are the pitfalls I need to avoid? 

I was able to find out that he is motivated to sell because he got a DUI and it really put him in a bad situation. He's not able to work right now. He has sold several of his other properties already and has 2 more, including this one. I did a drive-by and property looks great from the outside. We have a visit scheduled for Saturday. I would love your insight. Please and thank you.
