A qualified mortgage is a guaranteed loan meeting the requirements of this part and applicable Agency guidance, as well as the requirements in 12 CFR 1026.43(e)(2)(i) through (iii) and 12 CFR 1026.43(e)(3). An extension of credit made pursuant to a program administered by a State Housing Finance Agency is exempt from this requirement as defined in 12 CFR 1026.43(a)(3)(iv). Lenders will be allowed to cure unintentional errors and retain the qualified mortgage status if the conditions set in 12 CFR 1026.31(h) are met.
