I was also getting credit card balance transfer offers at 0% promotional rates for a year to a year and a half and I started transferring my HELOC balances to the promotional credit cards.

I assumed since they would profit too, they’d guide me correctly.But what they didn’t tell me was that on top of the $10,000, they charge nearly $200 per month for software to "learn" from.

I don't take credit cards but I believe stripe does.   

I have them process credit card payments.

Plumbers typically charge $45–$200 per hour.

I don't require it through Airbnb, but I do through Vrbo, because they are notorious for not backing you up when a guest does a charge back on their credit card. 

Let them pay the deposit with a credit card.

Once you have the desired amount of business credit for the downpayment and have activated the cards, upload the card(s) that you'll be using to Plastiq, ( preferably Visa for real estate from what I'm told ).

To me a scammer is like a well known note investor in austin who as an example went to write a book and charged people $500 to write a chapter in the book and took the money and never published it.
