Reverse mortgages: how a HECM actually works

What you’ll learn in this guide:

• The basic mechanism: how a reverse mortgage actually converts home equity into cash
• What it really costs, beyond the headline “no monthly payment” pitch
• The obligations that remain even though there’s no mortgage payment
• What happens to the loan, and to heirs, when the borrower moves out or dies
• Why HUD-approved counseling exists, and what it actually covers

“How does a reverse mortgage work” is one of the most-searched, least-understood questions in retirement finance

Most of what’s published about reverse mortgages is written by lenders trying to originate one, which tends to either oversell the upside (“turn your home equity into tax-free cash!”) or bury the costs and obligations in fine print. The mechanism itself is genuinely useful to understand on its own terms, independent of whether it’s right for any individual situation — which is the goal of this guide.

The basic mechanism

A Home Equity Conversion Mortgage (HECM) — the FHA-insured version of a reverse mortgage, and by far the most common type — lets a homeowner age 62 or older convert part of their home equity into cash without making monthly mortgage payments. Instead of the homeowner paying the lender, the lender pays the homeowner: as a lump sum, a line of credit, fixed monthly payments, or some combination. The loan balance grows over time as interest accrues, rather than shrinking the way a traditional mortgage balance does, and the balance becomes due when the homeowner sells the home, moves out permanently, or dies. The HUD HECM program page is the official source for current loan limits and program rules — the 2026 maximum claim amount is just over $1.2 million (this limit adjusts annually — the HUD HECM program page has the current figure).

What it actually costs

The “no monthly payment” framing obscures that a HECM isn’t free. Typical costs include an upfront mortgage insurance premium (around 2% of the home’s appraised value), an annual mortgage insurance charge (around 0.5% of the loan balance), an origination fee (capped, but can run up to several thousand dollars), and ongoing interest that compounds on the growing balance — most HECMs carry a variable rate, meaning the balance can grow faster than expected if rates rise. These costs are usually financed into the loan rather than paid out of pocket, which is part of why they’re easy to underweight when first hearing about the product — the money never visibly leaves a bank account, but it does reduce the equity left in the home. The FTC’s consumer guide to reverse mortgages breaks down the full fee structure.

The obligations that don’t go away

A reverse mortgage eliminates the monthly principal-and-interest payment, but not these ongoing obligations: property taxes, homeowner’s insurance, and home maintenance all have to stay current, because falling behind on any of them can trigger default and foreclosure — a fact that surprises people who hear “no payments” and assume the home is fully covered. The home must also remain the borrower’s primary residence; an extended stay away from home (commonly, more than 12 consecutive months in a care facility) can make the loan come due, with some protections for a non-borrowing spouse who remains in the home.

What happens at the end

When the loan becomes due — sale, permanent move, or death — the balance (principal plus accrued interest and fees) has to be repaid, typically through selling the home. Because a HECM is a “non-recourse” loan, neither the borrower nor their heirs ever owe more than the home is worth, even if the loan balance has grown larger than the home’s value by the time it’s repaid — the FHA insurance covers that gap, not the borrower’s other assets or estate. Heirs who want to keep the home can typically do so by paying off the loan balance (or 95% of the home’s appraised value, if lower) rather than the full accrued amount.

Why HUD-approved counseling is required, not optional

Every HECM borrower is required to complete a counseling session with an independent, HUD-approved counselor before closing — not a sales conversation, but a structured walk-through of how the loan works, its costs, and its effect on the borrower’s own finances and any heirs. This requirement exists specifically because the product has a long history of being misunderstood or oversold; treating the counseling session as a real opportunity to ask specific numbers questions, rather than a box to check before closing, is the most useful step in this entire process.

A note on how this fits the bigger housing-finance picture

A reverse mortgage is one of several ways to access home equity in retirement, alongside selling and downsizing, a traditional home equity line of credit, or simply staying and not tapping the equity at all. Home equity options in retirement covers how a HECM compares to those alternatives, and Aging in place: what your home may need and what it costs covers one of the more common reasons people consider tapping equity in the first place. For the specific numbers in any individual situation, HUD-approved counseling and a fee-only financial planner are better positioned to model the tradeoffs than any general guide.
