Deferred principal is a portion of your mortgage balance that your lender moves into a separate bucket so it doesn’t factor into your monthly payment. You still owe every dollar of it. It just sits quietly on the loan, usually without accruing interest, until a specific event forces repayment: the loan matures, you sell the home, you refinance, or title transfers. The tool is used to lower a monthly payment during or after a hardship without the lender actually forgiving any debt.
How the Split Balance Works
When a lender agrees to defer principal, your total mortgage debt gets divided in two. The first piece is the active balance, which you keep paying down each month through regular principal-and-interest installments. The second is the deferred portion, which is held as a static figure at the back of the loan. Your monthly payment is recalculated using only the active balance, which is why the payment drops, sometimes significantly.
The deferred amount is typically documented through a subordinate promissory note or a modification to the original deed of trust. That note creates a separate lien on the property, sitting behind your primary mortgage. You remain legally responsible for the full amount. Think of it as a tab you’re running with the lender. You will settle it eventually, but you’re not chipping away at it every month.
When the Deferred Amount Comes Due
The deferred balance doesn’t require monthly payments, but it must be satisfied eventually. The specific triggers depend on the program, though they overlap heavily. Across virtually every deferral arrangement, the full deferred amount comes due when any of these events occurs:
- Loan maturity. At the end of your mortgage term, the deferred amount is owed as a lump sum alongside your final payment. Modification agreements often extend the term to 30 or 40 years from the modification date, so maturity may be decades off.
- Sale of the property. Selling triggers full repayment. The deferred balance appears on the payoff demand your title company or escrow officer requests from the lender and is paid from sale proceeds at closing.
- Refinancing. Refinancing the primary mortgage generally requires paying off the deferred balance, because the new lender wants a clean first-lien position. One notable exception: HUD will subordinate an FHA partial claim to a streamline refinance, meaning you can refinance without paying off the deferred piece.1HUD. Mortgagee Letter 2025-06 Updates to Servicing, Loss Mitigation, and Claims
- Transfer of title or assumption. Transferring ownership or allowing someone to assume the mortgage triggers repayment under most programs.
If you miss the deferred balance when it comes due, the consequences mirror a standard mortgage default. The lien stays recorded against the title until the debt is satisfied or formally released, and foreclosure is possible if the balance goes unpaid at maturity or if sale proceeds fall short. Keep your modification documents in a safe place so you know the exact dollar figure and the specific triggers written into your agreement.
Does Deferred Principal Accrue Interest?
In most federal programs, no. Under FHA partial claims, the subordinate note is explicitly zero-interest.1HUD. Mortgagee Letter 2025-06 Updates to Servicing, Loss Mitigation, and Claims The VA’s partial claim program is likewise a no-interest subordinate loan.2Federal Register. Loan Guaranty – COVID-19 Veterans Assistance Partial Claim Payment Program HAMP modifications split the balance into an interest-bearing principal amount and a non-interest-bearing forbearance amount.3Internal Revenue Service. Principal Reduction Alternative Under the Home Affordable Modification Program
The practical effect matters. If you owe $300,000 total and $100,000 is deferred without interest, the lender calculates interest only on the active $200,000. Your monthly payment reflects the smaller number, and the deferred $100,000 doesn’t grow. When you eventually pay it off, you owe exactly what was deferred, nothing more. Confirm the interest terms in your own modification agreement, though. Proprietary lender programs that aren’t governed by Fannie Mae, Freddie Mac, FHA, or VA guidelines may structure deferrals differently.
Programs That Create a Deferred Balance
Several federal programs build deferral into their loss mitigation toolkit. The rules differ, but the underlying concept is the same: reduce what you owe each month now, push the rest to later.
Fannie Mae and Freddie Mac Payment Deferrals
If your mortgage is backed by Fannie Mae or Freddie Mac, both agencies offer a payment deferral option. Under Fannie Mae’s program you’re eligible if your hardship is resolved, you can resume full monthly payments, but you can’t afford to reinstate or repay all the missed amounts at once. The mortgage must be a conventional first-lien loan originated at least 12 months before the evaluation date, and you generally need to be between two and six months delinquent.4Fannie Mae. Payment Deferral Fannie Mae also offers a disaster payment deferral for borrowers who missed up to 12 payments due to a disaster-related hardship.5Fannie Mae. Payment Deferral
Freddie Mac’s version is similar. Under expanded criteria effective since October 2023, payment deferrals are available to eligible borrowers who are 60 to 180 days delinquent, and borrowers no longer need to make consecutive monthly payments before completing the deferral. Freddie Mac allows up to 12 months of deferred principal and interest payments.6Freddie Mac. Payment Deferral Solutions
FHA Partial Claims
For FHA-insured mortgages, the equivalent tool is the partial claim. HUD advances funds to your servicer to cover missed payments and, where applicable, a principal deferment. That amount becomes a zero-interest subordinate note payable to HUD. Repayment isn’t required until the mortgage matures, the property is sold or transferred, the mortgage is assumed, or the loan is paid off. The total outstanding partial claim balance cannot exceed 30 percent of the mortgage’s unpaid principal balance as of the date of default.1HUD. Mortgagee Letter 2025-06 Updates to Servicing, Loss Mitigation, and Claims
VA Partial Claims
The VA operates a similar program for VA-guaranteed loans. Under the COVID-19 Veterans Assistance Partial Claim Payment Program, the VA purchases the veteran’s delinquent amounts from the servicer and creates a no-interest subordinate loan. Repayment comes due when the veteran transfers title or refinances or pays off the primary mortgage. The partial claim amount cannot exceed 30 percent of the unpaid principal balance as of the date the veteran entered forbearance. Veterans may prepay the subordinate loan in whole or in part at any time without penalty, and servicers are prohibited from charging any fees for the program.2Federal Register. Loan Guaranty – COVID-19 Veterans Assistance Partial Claim Payment Program
HAMP Modifications Still in Effect
The Home Affordable Modification Program made principal deferral a household concept during the 2008 housing crisis. HAMP stopped accepting new applications on December 31, 2016, but many borrowers still carry HAMP modifications with deferred balances that won’t come due for decades.7U.S. Department of the Treasury. Home Affordable Modification Program (HAMP) If you received a HAMP modification, the deferred balance documented in your modification agreement is still a live obligation.
Refinancing or Selling With a Deferred Balance
Refinancing when you have a deferred lien is more involved than a standard refinance. The deferred balance creates a subordinate lien, and a new lender wants first-lien priority. That means either paying off the deferred amount from refinance proceeds or getting the holder of the deferred lien to sign a resubordination agreement, formally agreeing to stay in second position behind the new mortgage.
Fannie Mae requires execution and recordation of a resubordination agreement when a refinance pays off the first mortgage but leaves subordinate financing in place.8Fannie Mae. Subordinate Financing Getting HUD, the VA, or a private servicer to agree to resubordinate can be slow and uncertain. The FHA streamline refinance is the clearest exception, since HUD will subordinate its partial claim lien to a streamline refinance without requiring payoff.1HUD. Mortgagee Letter 2025-06 Updates to Servicing, Loss Mitigation, and Claims Outside that narrow case, plan on the deferred balance being part of your payoff.
Selling is more straightforward. The deferred balance appears on the lender’s payoff demand and is paid from sale proceeds at closing. The number comes off your equity, so sellers with large deferred balances sometimes find they walk away with far less than the sales price suggests.
Taxes if the Lender Later Forgives Any of It
As long as your deferred balance remains an obligation you must repay, there’s no tax impact. Trouble starts if the lender eventually cancels some or all of the deferred amount. Under general tax rules, canceled debt counts as taxable income, and a lender who reduces your principal balance through a modification creates income you must report.9Internal Revenue Service. Publication 4681 – Canceled Debts, Foreclosures, Repossessions, and Abandonments
For years, homeowners could exclude up to $2 million of forgiven mortgage debt from income under the qualified principal residence indebtedness exclusion. That provision expired at the end of 2025. Under current law, qualified principal residence indebtedness cannot be excluded from income for discharges completed or agreements entered into after December 31, 2025.10Office of the Law Revision Counsel. 26 U.S. Code 108 – Income From Discharge of Indebtedness This is a major change for 2026. If a lender forgives any portion of your deferred balance now, you’ll likely owe income tax on it unless you qualify for one of the remaining exclusions.
The exclusions still available include bankruptcy (debt discharged in a Title 11 case), insolvency (your total liabilities exceeded your total assets at the time of discharge), and qualified farm or real property business indebtedness.9Internal Revenue Service. Publication 4681 – Canceled Debts, Foreclosures, Repossessions, and Abandonments Insolvency is the one most homeowners with deferred balances should understand. If you’re underwater and have limited other assets, you may be insolvent enough to exclude all or part of the forgiven amount. When a lender cancels $600 or more of debt, it files a Form 1099-C reporting the canceled amount to the IRS.11Internal Revenue Service. Instructions for Forms 1099-A and 1099-C
Credit Reporting and Future Borrowing
How a deferral appears on your credit depends on your payment history before and after the modification. If you were current when you entered a forbearance agreement that led to the deferral, your servicer should continue reporting the account as current.12Consumer Financial Protection Bureau. Manage Your Money During Forbearance If you stopped making payments without a forbearance in place first, those missed months likely hit your report as delinquencies before the modification was finalized. Once the modification takes effect and you resume on-time payments, the account should report as current going forward, though prior delinquencies remain on your report for seven years.
The deferred balance also affects your ability to qualify for new credit. When you apply for a future mortgage or home equity line, the lender calculates your debt-to-income ratio. Federal lending programs generally count deferred payment obligations in that ratio. USDA’s single-family housing program, for instance, includes deferred payments in the total debt ratio calculation.13USDA Rural Development. Ratio Analysis – Single Family Housing Guaranteed Loan Program Even without a monthly payment, underwriters treat the deferred amount as a liability that will eventually come due, which can reduce the loan amount you qualify for.
What Happens if the Borrower Dies
The deferred balance doesn’t disappear at death. It’s a lien on the property, and the borrower’s estate remains responsible for satisfying it. In probate, a claim can be filed against the estate for the full amount owed, including any deferred balance. If estate assets fall short, the holder of the lien may seek to collect from the property itself through foreclosure or from assets in the hands of heirs, depending on the loan program and state law.
Heirs who want to keep the property have options, but the deferred balance is a separate subordinate note with its own terms. Protections that stop a lender from calling the primary mortgage when a relative inherits don’t automatically cover the deferred piece. Heirs should contact the servicer promptly to find out whether they can assume the loan and the deferred obligation or whether the deferred amount comes due on transfer. Waiting invites default proceedings.
Paying Down the Deferred Balance Early
If your finances improve and you want to chip away at the deferred amount before it comes due, your ability to do so depends on the program. VA partial claims explicitly allow prepayment in whole or in part without any charge or penalty.2Federal Register. Loan Guaranty – COVID-19 Veterans Assistance Partial Claim Payment Program FHA-insured loans generally prohibit prepayment penalties as well. For conventional loans modified under Fannie Mae or Freddie Mac guidelines, review your modification agreement for prepayment terms. Most borrowers find there’s no penalty for paying early, but directing a payment specifically toward the deferred balance (rather than having it applied to the active loan) usually means contacting your servicer with explicit instructions.
The payoff is simple. Paying down the deferred balance early reduces the lump sum you’ll owe at maturity or sale, and it lowers the total lien amount on the property. If you plan to sell within a few years, even modest payments toward the deferred amount mean more equity at closing.
