What is HAMP (home affordable modification program)?

The Home Affordable Modification Program (HAMP) was a federal loan modification program created in 2009 under the Making Home Affordable initiative to help homeowners avoid foreclosure during the Great Recession. HAMP was a crisis-era loan-modification program whose eligibility and payment rules changed over time. Participating servicers could lower eligible borrowers' payments through rate reductions, term extensions and principal forbearance. It is closed to new applications.

Key facts

  • HAMP permanently modified approximately 1.8 million mortgages between 2009 and its expiration on December 31, 2016 — preventing an estimated $25 billion in foreclosure losses but falling short of the Treasury's original target of 3-4 million modifications.
  • The program used modification steps applied in a set order to lower the payment — capitalizing arrears, reducing the interest rate, extending the term and forbearing principal — and its exact terms and targets changed over time.
  • HAMP generally used a trial-payment stage before a permanent modification, which was controversial — an estimated 72% of trial modifications eventually converted to permanent, while the remainder often ended in foreclosure with accumulated arrears.
  • The program was funded by $75 billion from TARP (Troubled Asset Relief Program), though actual disbursements were far less — approximately $27 billion was ultimately spent on all Making Home Affordable programs combined.
  • HAMP's legacy shaped modern loss mitigation: FHA maintained a separate HUD-administered loss mitigation framework, Fannie Mae and Freddie Mac Flex Modification programs adopted similar waterfall structures, and CFPB Regulation X codified many HAMP-era servicer obligations.

How Did HAMP Work?

HAMP required servicers participating in the program to evaluate borrowers for modification eligibility, subject to program and loan eligibility requirements. The evaluation used a standardized "waterfall" of modification steps to lower the borrower's payment:

  1. Capitalize arrears: Add past-due payments, fees, and costs to the principal balance
  2. Reduce interest rate: Lower the rate, subject to the program's floor, with scheduled rate increases in some modifications; the signed agreement sets the terms
  3. Extend term: Push the maturity date out
  4. Forbear principal: Set aside a portion of principal as a non-interest-bearing balloon due at maturity, sale, or refinance

Each step was applied in order until the program's payment target was reached. A payment target was not the only test: a loan modification can also be denied because of a net present value calculation, which is a separate investor test.

Why Did HAMP Fall Short of Its Goals?

The program faced several structural problems:

  • Servicer implementation: Major servicers (Bank of America, JPMorgan, Wells Fargo) were overwhelmed by volume and incentive misalignment — they collected fees regardless of modification outcomes
  • Documentation delays: Servicers repeatedly lost borrower documents, leading to the "dual tracking" scandal where homes were foreclosed while modification applications were pending
  • Trial period failures: Many borrowers made trial payments but never received permanent modifications, ending up worse off than before (with capitalized arrears)
  • Investor pushback: Some private-label mortgage-backed securities investors objected to modifications, creating legal uncertainty
  • Re-default rates: Approximately 30% of permanent HAMP modifications eventually re-defaulted within 3 years, suggesting that for many borrowers, the underlying affordability problem was not resolved

What Replaced HAMP?

After HAMP expired in 2016, loan modification continued through proprietary and GSE programs:

  • Fannie Mae/Freddie Mac Flex Modification: Adopted HAMP's waterfall structure with some simplifications. Targets a 20% payment reduction rather than a fixed DTI ratio.
  • FHA Loss Mitigation: FHA maintained a separate HUD-administered loss mitigation framework for FHA-insured loans after Treasury HAMP expired.
  • VA Loan Modification: The VA developed its own modification waterfall for VA-guaranteed loans.
  • Proprietary modifications: Servicers of private-label mortgages offer their own modification programs without standardized terms.

The CFPB's Regulation X (12 CFR § 1024.41) codified many HAMP-era protections into permanent law, including the requirement to evaluate borrowers for loss mitigation before foreclosure and the prohibition on dual tracking.

Questions about HAMP

Is HAMP still available?

No. HAMP expired on December 31, 2016. Homeowners seeking loan modifications today should contact their servicer about current modification programs (Flex Modification for Fannie/Freddie loans, FHA loss mitigation for FHA loans, or proprietary programs). A HUD-approved housing counselor can help navigate options: 800-569-4287.

How many homeowners did HAMP help?

HAMP permanently modified approximately 1.8 million mortgages. An additional 1.6 million homeowners received trial modifications that did not convert to permanent. The program's original goal was 3-4 million modifications, so it reached roughly half its target.

What was the HAMP waterfall?

A standardized sequence of modification steps applied in order: capitalize arrears, reduce the interest rate, extend the term, forbear principal — each step applied until the program's payment target was reached. Eligibility involved more than that target, and the exact terms changed over time.

Did HAMP reduce principal?

HAMP's standard waterfall forbore (set aside) principal rather than reducing it. Some historical modification programs, including the HAMP Principal Reduction Alternative (PRA), offered principal reduction. The terms and who took part varied by program and servicer.

What is the difference between HAMP and current loan modifications?

HAMP used federal program standards for participating servicers and eligible loans; it was not a universal option for every mortgage. Current modification programs are designed by Fannie Mae, Freddie Mac, FHA, or individual servicers with different target payment reductions. However, the basic waterfall structure — rate reduction, term extension, principal forbearance — originated with HAMP.
