In 2020 the house was 75% done and I had to re appraise the house and get a new loan to pay off all my credit cards, personal loans, etc.

But if you are already worried about paying back that HELOC out of the property you buy, you are creating a house of cards from the start depending on how good of a buyer you are.

i get cards, calls and texts every day from wholesalers for my little portfolio - so that shows you how much competition there is out there.it's also tough to do as a beginner in real estate, because the best wholesalers surface strong deals and know how to estimate a rehab.  

They were actively trying to open credit card accounts in his name I seen on his credit report.

Or if we start taking direct bookings, we can get a deposit or have a card on file to cover damages that they cause. 

As an example: the lender asks for a payoff letter for a credit card or some other debt so that it can be paid off at closing.

Also, do you have any 0% interest credit card offers that could help fund/pay the roofers in the meantime?

Most sellers want to hold a business card.

Nowadays you need to consider credit card functionality, too.

I haven't done so yet, but it's a good card to keep up your sleeve for when you are ready.
