Hi Penelope, Thanks for signing up - we love to hear from borrowers.
As to your question, I would say it all depends on your credit. If your credit has improved since the last time you applied for a loan then I think it is highly likely that you will receive a lower rate and will be able to pay off your Lending Club loan. You can always apply for a loan to discover your rate at Prosper without hurting your credit score.
Good luck and let us know what happens.
