What is this house worth to a wholesaler

[Jessica Rodriguez]

I have a a motivated seller who is going to take highest bidder by Monday. 3 bed 2 bath 1500 square feet. Home is near an elementary, walking distance from grocery and parks. Home needs new roof, one bath completely re done and doesn’t have central air. The county has the home assessed at 120,000 for year of 2017 but owner is asking 73,000 on Zillow. What would be a fair offer all things considered.
