( A well written (skinny) contract, all the right protection clauses and honest disclosures... automatic extensions.)This business has so many moving parts, seller personalities, dealing with relatives and third party know-it-alls, the estate, seller's agents or lawyers --- be prepared to deal with these gate keepers! 

I like @Rick's response - - UNLESS you are a party to the transaction (for clarity, the buyer OR the seller) you'll only muddy the water and if you were involved as a contractor at any capacity, you can easily get your name sullied needlessly. 

The parties involved have 10 days to file an objection to the sale before a certificate of title is issued.  

An individual in a long term care nursing facility is likely to have diminished capacity.A little detective work may lead you to the facility, but that may not be helpful as laws will interfere with facility revealing if your party resides in their facility.You might find your owner but not be wise to get your purchase docs signed by this person. 

Although I stay away from the low income properties for the most part I know a lot of the guys in that space and could maybe give you some recommendations. 

The harder part is getting and choosing comps.

In our area judges are overturning subject to deals when they are completely one sided and one party gets nothing and another party get something.

One party took extra long to see the place, so they overlapped with another appointment.

This deal almost died multipule times, with issues regarding third party approval of the short sale, and FHA required repairs in order to close, and each time I hit a road block, and my agent and myself were scratching our heads Upen was there to point us in the right direction. 

The  reality is you may REQUEST an extension, but it doesn't have to be honored, and of course both parties waste time and effort.
