In Mist Of Deal 1 Owner Dies

[Michael Williams]

I've negotiated the price,have a buyer ready, put the contract in the hands of the son of the owners and the father, who is on the deed with his wife, passed away 5 days ago There is no will. Where does this put my contract? Do I have a certain number of days to get the deal done or is it on hold until probate? I am in Memphis Tennessee.

Son is NOT on the deed. 

The mother has given her son permission to sell to me. Does he need a power of Attorney? 

He is also open to a payment plan where I can pay him $XX down and monthly for the rest. Any pointers and advice.  I really have the option to hold with owner financing or flip to a buyer.
