Advice on Deal Structure

[Mike Abel]

I received a call from a motivated seller and went to see the property today. It is a multi-family built between the 1920s-1940s. It has remained as a generations passed down property so little to no public information available. They own the property free and clear, but the condition of property is very bad and practically needs to be demolished. There is a main building with 5-6 bedrooms. Another building that is a studio, and 1-2 other buildings. There is so much stuff in all the buildings it's very difficult to move around and identify all rooms/bathrooms. All the buildings are literally packed with boxes, some furniture, and lots and lots of junk. I am having a tough time determining an ARV. Looking for advice on if there could be a deal and how to structure or if maybe better to refer to someone else and collect a finders fee or refer it to a company that does an estate sale.

Also, the Seller is asking for moving expense only and they owe ~$70k in back taxes.
