FHA HAMP is designed to help FHA-insured borrowers who meet HAMP eligibility requirements to avoid foreclosure by permanently reducing their monthly mortgage payment through the use of a partial claim. The partial claim defers the repayment of mortgage principal through an interest-free subordinate mortgage that is not due until the first mortgage is paid off. Under the partial claim option, lenders are authorized to advance funds on behalf of a borrower, to reinstate a delinquent loan that is up to 12 months delinquent. HAMP will allow HUD to bring eligible FHA borrowers' payments down to an affordable level. This will be accomplished by bringing the mortgage current, buying down the loan by up to 30 percent of the unpaid principal balance and deferring these amounts in a partial claim.
