All credit cards are lines of credit but not all lines of credit have a card attached to them.

Have you looked into what rates you can get on just a hard money loan and how does that compare to the APR on this card?

Lines of credit = pulling cash from a couple of credit cards with high limits that I have available (typical 22-23%). 

I had business cards printed identifying myself as a commercial broker specializing in automotive properties2.

Merchants Bank MN See Pavel UshakovPenFed - max 3 other properties, 89% LTV Regions- yes HELOC but no LOC SCCU Florida 70% LTV, 6.25% interest only, not LLC Signature Federal Credit Union 75% LTVSound CU "non-owner occupied HELOC, capped at $150K and interest rates are prime + 2%, 3% or 4%, based on credit, not to exceed 70% ltv.”S&TTCF BankTD Bank TIAA Direct was EverBank Tower FCU, all states except TX, max 45 DTI, green card ok.

I have some telling me that I can do minor repairs on the property and use a credit card to purchase materials (HVAC Filters, caulk or even paint) and my IRA can pay the credit card directly (keeping it at arm's reach).I also see where this interpretation of services versus repairs could be considered a "Grey" area and I am just looking for something that turns it at least a little darker.

Since I was 18 I've always used a debit card.

I have a checking account and a credit card under my LLC.

If I know it's scammy, I can get out and refund with my credit card.

Typically a credit card balance does not need to be paid off to include the expense on the current year return.
