Reverse mortgages largely have a bad reputation. But in certain circumstances, they can make smart financial sense, experts say.
Consider a single retiree who owns her home outright and has nearly seven figures in a tax-deferred account. In a strategic move, she decides to open a Home Equity Conversion Mortgage (HECM) line of credit as insurance against a market downturn she cannot predict. An HECM is a specific type of reverse mortgage.
Her balance sheet: $920,000 in a 401(k) and a $740,000 paid-off home. At 67, the available HECM credit line runs roughly $280,000. By 80, if untouched, that unused line grows to roughly $420,000. The credit is non-callable and available on demand.
HECMs got a bad name in the 2000s when they were marketed to cash-strapped seniors as a way to tap home equity for daily expenses. But the product has evolved. Researcher Wade Pfau and others have shown that opening a HECM line of credit early in retirement, before you need it, can meaningfully extend portfolio longevity. The unused line grows at the loan’s interest rate plus the FHA mortgage insurance premium (MIP), independent of what the home’s market value does.
The biggest threat to a 67-year-old’s portfolio is the order of returns, not the 30-year average. A retiree who hits a 25% bear market in years one through three and sells assets to cover living expenses locks in losses that compounding never recovers. The same returns in reverse order produce a wildly different ending balance.
That is the math her HECM is solving. When markets are up, she draws from the 401(k). When markets are down, she draws from the HECM line instead, letting depressed portfolio assets recover before she touches them.
To be sure, HECMs carry real costs. Origination fees, third-party closing costs, and an upfront FHA mortgage insurance premium typically run several thousand dollars at closing, and an ongoing annual MIP accrues against the loan balance. If she never draws on the line, that upfront cost is the price of the insurance policy. If she draws heavily, interest compounds on the borrowed balance for as long as she lives in the home.
HECMs are non-recourse loans, so she or her heirs will never owe more than the home is worth at sale. She must keep paying property taxes, homeowners insurance, and maintenance, or risk default. HUD requires HECM borrowers to complete counseling with an independent, HUD-approved counselor before closing, a consumer protection most retirees skip past.
Some experts say retirees considering an HECM should get started in their 60s and leave it untouched until needed. Waiting until a portfolio crash forces the conversation lands you at the lender’s door when home values are weakest and lending standards tightest.
HECMs make less sense for retirees who plan to move within five to 10 years, since closing costs do not amortize meaningfully over short holding periods. They also aren’t appropriate for those determined to leave the home to heirs free of any lien.
What to Evaluate First
- Map your withdrawal sources by market condition. Decide in advance which account funds living expenses in an up market and which funds it in a down market. The HECM only helps if you actually use it as the downturn buffer.
- Price the upfront cost against the insurance value. If origination plus upfront MIP runs $10,000 to $15,000, ask whether avoiding one bad sequence of returns over a 30-year retirement is worth that premium. For some retirees with seven-figure portfolios, it makes sense, experts say.
- Treat the line as insurance, not cash. Drawn balances compound at the loan rate plus ongoing MIP.
The mistake to avoid: waiting until you are 78 and watching a bear market eat 30% of your portfolio before you call a HECM counselor. By then, your home may appraise lower, rates may be higher, and the credit line you could have locked in at 67 will be smaller and more expensive. Used correctly, this product is boring on the day you open it and potentially invaluable on the day you finally need it.
