The interest rate on the 2nd is close to credit card rates, so it's not really worth it in my opinion. 

Loans can’t connect to the bank feed like checking or credit cards because banks/creditors don’t send that kind of data.

Also, syncing the bank feeds to your banks and credit card would be where you need to figure out.

I do not have a lot of cash flow in general, so I would be taking an interest free credit card to pay for the furniture and if I evened out for a year then started making profit that would be great.

used the calculator, I think it uploads from there

They do not have an automated way to capture credit card transactions.

I have tried very expensive courses but they talk a big game and just leave you in credit card debt.

You say credit cards, loans, car repo, student loans, collections and child support.
