Look for a lender that reports to credit bureaus
If your installment loan provider doesn’t report to a credit bureau, an installment loan can’t have any impact on your credit score at all. It can still hurt your credit score if it goes into collections — that gets reported to credit bureaus regardless of the lender.
If you’re interested in improving your credit when you borrow, go for a lender like OppLoans or Rise that report to at least one of the three main credit bureaus: TransUnion, Equifax and Experian.
