not so wholesale in Houston

[Todd Shampoe]

I am new to flipping and have been looking at a turnkey wholesale company to get properties. As a ball park I am using the following formula to determine the buy price. (.70 * ARV)- repair cost. So a 100K ARV house that needs 20K in work, I would try to buy it at 50K. The recent list I got from the wholesaler is as follows:
(arv)160K *.70= 112,000-(repairs)30K= 82K buy price. But in this case the wholesaler wants 95K..
it seems that they are selling them to rehabbers for 60 to 70% of ARV is this right?
