I get turned down a lot on usually only get the stinky ones with unpleasant cleanup, but that pays off. 

(currently dealing with unpleasant people )...

Before I'd go forward I'd get real contractor numbers for the rehab, you could be unpleasantly surprised.Also I'd check with zoning for violations, rental inspection, and whether 8 units are legal.

@Benjie DeVera Three rather large, warty, and unpleasant possible issues come two mind:1) The partition of the house into four units was done w/o permits - this means there is no verification that the work was done correctly and in compliance with building an fire codes {are all the units separated with an appropriate fire break}?

Let them know you can help buy unwanted real estate.  

I would encourage you to use caution in how you approach the situation, the loss of someone is never an easy situation, but sometimes it does cause unwanted problems like inherited real estate.  

Unpleasant

I definitely agree that there are advantages to having a well and septic in the long run since there is no never ending monthly bill.A bad well or septic tank can definitely make a deal go sideways if the high costs to repair or replace are not factored in when purchasing.You can either have them inspected and if they fail adjust your offer accordingly.If you just purchase blind with no inspections and not factor in the potential costs, it can turn out to be an unpleasant surprise if they are bad.

Sometimes it really is a win for a seller to save their credit, or walk away with cash quickly, or get rid of an unwanted property without much effort on their part.

Some places put a lot of "add on" fees after the sale which can be an unpleasant surprise.
