Probate/Wholesale situation need creative advice

[John Stokes]

Ok, so here is the real-life scenario:

A friend of mine is currently living in a property willed over to him by his mother 6 years ago when she passed. According to him he has been living there although he never finalized the Probate process. So, technically, the house isn't even in his name yet...?

He's now $11k behind on property taxes and the house is up for auction on April 24th 2017.

The house has every possible problem from aesthetics, to sewage issues, lead paint, and even mold.  

He has an offer from a wholesaler attached below...

What I cropped out to edit out his name says 

"Received from BUYER 1 and BUYER 2 Husband and wife herein designated as BUYERS, the amount set forth below as earnest money deposit on account of the purchase price of $140k  for the real property situated in 123 MAIN ST USA

The Seller by virtue of a will and a probate which will begin within 5 days of the acceptance of this agreement, SELLERS NAME, now residing at the residence"

The rest of the Agreement is below. 

He's behind on the taxes, never took ownership in the 6 years living there.

The offer he has doesn't seem all that bad...

My question is this...He wants to stay there for another year if possible and I happen to know a wholesaler here locally that would jump if the numbers were right.

Given the circumstances, what is the BEST deal possible for all 3 parties? I'd like to make my buyer (the investor) a sweet deal...I'd like my friend to come out on top...and I'd like a cut... ANY TIPS?
