Funding Question for a flip

[Marc Holland]

Hey everyone! I need some help! I have a house in Sherman Texas under contract. We're scheduled to close July 2nd. We are going through Wildcat lending for our hard money lender. I was under the impression that we pay them on the back end of the closing once we sell the house not on the front end when we're purchasing it. So I don't have the funds necessary to close on July 2nd. Anybody have any ideas for other ways to fund the deal? 63K purchase price. 45K repairs. 140K-150K ARV. Thanks!
