Non-QM lenders must do the same. But they often stretch the box -- sometimes more than a little -- based on the borrower’s credit score and loan-to-value ratio, as opposed to debt-to-income ratio. Quontic Bank is just one of many non-QM lenders. Meanwhile, the CFPB has proposed allowing non-QM loans to become qualified mortgages three years after their origination if they meet certain qualifications. The objective, the bureau says, is to “incentivize” more lenders to make non-QM loans they otherwise might not.
