You can try social lending website like Lending Club. Depending on your credit it can go lower than 11% APR. Or if you can pay it back really quick use balance transfer checks from your CC.
10.99% APR is pretty good for signature loan, given that it is an unsecured loan.
When my score was in the low 700s before my last app spree they offered me like 20% for a 2K loan.. (both lending tree and prosper) .. but the benefit is you can check the rate with a SP from their sites
Isn't Chase Slate 0 BT fee? Depending on your monthly expenses it can also be fairly easy to avoid BT fee by simply charging everything to your 0% cards and the. Using the money you would normally use to pay your bill for whatever you need the loan for. That way you take advantage of your purchase APR. whether that gets you the money quickly enough depends on how soon you need it and how much you can charge in a month.
The Chase Slate would be a good choice for BT, the only thing i would worry about with that would be what kind of CL would Chase issue on it.
