So on Fridays he would take a few complaint cards that came in about the Mac and Cheese and personally call the folks of course to hear him tell it was quite humorous calling ( normally a house wife) and explain NO I am the President of STauffer and I want to hear why or how we can improve our Mac and Cheese..

Do you have credit cards with places like Lowes and Home Depot that you can use to buy materials now and not need to pay off for maybe 90 days?

If you are an "authorized user" on your husband's credit card(s) you can benefit from his credit and start increasing your score.

I've seen investors use credit cards with a 0% APR promotion, business loans, but most times they have someone in their network privately lending them those funds.

Its a mortgage with a debit card.

We're going to furnish the property and I was wondering if anyone has done this, and if so what credit card do you recommend?

@Joseph FennerTo acquire 167 rentals, use creative financing strategies like the BRRRR Method, seller financing, partnerships, joint ventures, HELOC/Equity Loans, portfolio loans, credit cards, and business credit lines.

In that example, I was imagining that the investor made upgrades and improvements AFTER closing, either with their own funds, a personal loan, credit cards, etc.  

Just do it, tell them to send you some gift cards for the inconvenience lol otherwise they might have to call your note if its in their legal reach. 

National savings rates have plummeted, increasingly reliant on credit cards to fill financial gaps.
