The sale evidently resulted in Quest’s owners getting zippo (hearsay, working to confirm that). 

There's lots of properties for sale in the Smoky mountains so you may also have a larger selection of options to purchase as well.

Either way it would be a grey area, selling a house with a different amount of units/bedroom/bathroom seems extreme though. its an auction site, I have seen auction sites miss the fact there was additional lots in a sale.

We can pay what we need to, but putting 1/3 the sale cost of the house into a foundation repair doesn’t seem like a good option unless there’s absolutely no alternative.  

Any insights into the 5 condos for sale on S Gold St?

We could sell the house invest the money and pay his bills with the  investment proceeds but in order to do this we need to rehab the house which will still take a few months and obviously she needs to leave before we can put it for sale in order to get the best price.  

If they’re selling for a $400k+ gain they could look at a 1031 for:A super nice 2-4 unit they wouldn’t mind living in a unit of where the rental portion exceeds their 1031 sale. 

Might be for sale here on BP or for sure can probably find on Amazon/Ebay.You should also connected with @Henry Clark and https://www.biggerpockets.com/users/paultmooreIt seems like you are focusing on one property. 

This is a difficult sale... finding someone to invest is a difficult sale but asking them to invest for decades is going to be an almost insurmountable sale. 

A “syndication” is almost always a capital raise for the sale of a security/investment.
