@Stephen Hudley,
congratulations in finding this deal. Seems like you will make a nice profit and hopefully the owner will benefit nicely as well.
With that said, I want to mention that I hope people will consider the human factor here as well as the profit factor; with the human factor perhaps outweighing the profit factor. I have personal family experience with this sort of hoarding behavior and I can assure you, the underlying disease (perhaps in this case obsessive compulsive disorder or schizophrenia-related mental illness) is devastating as you probably can guess.
I'm sure noone who posted here meant any offense to the property owner when referring to the status of the home and, of course, we're all interested in how the deal was formed so having this post focus on the detailed RE aspects and not the human aspect is understandable. However, it would be nice to know how the property owner will benefit from the sale of the home - after all, we as investors are not only after profit right? Helping people out of seemingly insurmountable situations can be as rewarding as a "home-run" deal.
Best wishes
