How Do You Determine Your Wholesale Profit?

[Tennita Funmaker]

I haven't done any wholesaling yet.  I'm just starting to gather information.  My question is when you find a deal you want to wholesale how do you determine your own profit?  Do you start backwards with what rehabbers would want (30%ish margin or so?) and then determine your cut?  Or do you start with your margin goal and leave the rest for the rehabber?

IDK what the formula is, but the "wholesalers" that have sent me leads are asking about 90 pct of retail. Needless to say I haven't bought any of them. Perhaps they are just asking high and expecting a lowball offer. But I think a good wholesaler would be straight up and say Y is my price, X is the ARV, X1 is your closing costs, X2 is your holding costs, X3 is your profit
