Maintenance, the life cycle of commercial W/D, and the cost of converting from coin-op to debit card operated? 

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.

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

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.  

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

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. 

Tenants, "go into Holiday-mode" and start spending disposable income (and racking up their credit cards) on Thanksgiving feasts & trips, Xmas presents & trips, and finally NYE plans.3) Income Tax Refund checks start being received towards the end of February and corresponding, the rental market starts picking up again as tenants payoff their “Holiday Hangovers".4) Spring Fever starts, sometime in April-May, causing both sales & rental markets to start picking up.

You pay 4%  credit card fee . .
