Business Credit converted to Cash for Down Payment

[Menalik Archer]

I have 23k in business credit that I want to use for a down payment on an investment property. I have some cash as well. I've been following this other popular investor on Youtube and this is the method he uses to acquire property. After a year, he'll do a cash out refinance to pay off the credit cards and start the cycle over again. That all sounds fine and dandy but from my experience with purchasing my first home, the bank wanted to a paper trail of where every single cent came from-- I did FHA 3.5%. Even if I do a conventional, wouldn't the bank want to know where the money came from? I feel like there's something being left out. I've tried to call my mortgage lender for information on how this works. Haven't received any call back yet. Could he be doing a low doc mortgage for each property? I'm trying to purchase my first multifamily property. Any advice would be appreciated.
