Flipping formula 70% rule?

[Marko Balac]

Hey all, kinda of a newbie here but been a contractor for 17 years trying to get more into real estate. I’m getting a lot of deals sent to me but they very rarely meeting the 70% criteria. Am I over thinking this rule? Because a lot of the flips I’m seeing, Arv- minus PP- rehab I’m seeing alot of them at like 150k spread but it doesn’t meet the 70%. So Im wondering if there’s a different way to analyze it. What do you typical want out of it, I know out of the 150k there’s gonna be holding cost lender cost resale cost etc but how much does thag really come out to? Will there be about 80-100k left? 

Thanks!!
