Is there a service that will provide private lenders with payment history reporting on debtors’ credit reports?

I have a mortgage from a private lender (not a relative, a private institution). The mortgage does not show up on my credit report at all, which makes my credit score lower than it could be as TransUnion notes I am being penalized for not having mortgage history.

Your lender would have to pay the fees to subscribe to the credit bureau. It isn’t cheap. Does your lender use one of the other two credit bureaus? Not all creditors belong to all three.

There is an alternative for you but this would be just a one shot listing of the mortgage. There would be no updates which wouldn’t really help your score.
