Best option for selling to rehabber for most profit

[Kevin Sapp]

My 85 year old father in law has a house in Denver, Green Mountain Estates that he wants to sell soon. The house is split level, 4 levels, 3 bed, 2 3/4 bath, large two car garage with about 3000 total square feet including the unfinished basement.

The house is very dated, harvest gold bathroom fixtures, green stain, 2 hinge flat green/brown stained flat panel (luan) doors. Kitchen has cherry cabinets, but green cork floors and green wallpaper.

In y'all's experience what is it worth to a rehabber to hold the note and ask for a share of the profits? Other options to maximize profits?
