Unfortunately, I canceled about a month in when I realized the scam.I signed the contract in good faith and tried to dispute it with my credit card company, but they lied to the credit card company, showing them only the first contract I signed.

I prefer to have the least amount of banks as possible.Create a bank account that you already have a relationship with(Credit card or mortgage)The least amount of bank accounts is also ideal.

I know I could put furniture on 0% interest credit cards, but I would need 2+ years to pay it off and I don't want to have to jump through hoops to cycle a balance onto new cards. 

As far as the business card is concerned, to me personally I think having both things on one business card is acceptable .  

I'm curious why I did not receive it, as I paid in full, and it is already on my credit card!

Personally, I used a business credit card to fund a BRRRR deal, securing over $90K in credit with just an LLC and a solid credit score.There are many creative financing strategies available, so don’t let capital be a barrier.

The applicant needs a credit card to complete the process and they charge more than $25.A lot of landlords in Milwaukee do the same. 

Just wasn't in the cards for me.  

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. 

GEt some Credit Cards, spend a little every month and pay off, then get higher limits and repeat.
