How to back out a deal the proper way

[Lemont Williams]

So I've might've got my self in a deal that might not work for me how would I back out if we signed contract but it's not in escrow without having legal issues ?

Well before you back out of the contract you might want to consider renegotiating with the seller. 

I'd explain it to the seller exactly like you did in your post:

"didn't have good enough comps I thought it was worth about 85k arv and it seems to be 65 after doing more research" 

Work the lead until you know it's dead.
