Got my first deal under contract. Pay for closing with credit?

[Uchenna Egwuonwu]

Hello everyone! Through research on BP and listening to podcasts, I've finally found the confidence to pick up my first flip. I am partnering with an experienced investor that will coach my through the deal. He is also a broker and suggested that I use his brokerage to charge the closing costs and essentially get the money back in cash.

My question is, what other ways can I get this money into a bank account so that I can bring a cashiers check to closing? I'm expecting 22K total that I will need from a total of 40k in credit cards. From my understanding I can do one of a few things:

-Charge the total of 22k through my broker which will include the 3% convenience fee, costing me $660

-Buy $500 visa gift cards w/ 5.95 fee each, and depositing to my account costing me $261.80 (a lot of work)

-Get credit card convenience checks, which may or may not be charged as a cash advance.

Can anybody recommend an approach for me?
