A Home Equity Conversion Mortgage (HECM) is the FHA-insured reverse mortgage. Most people first hear about it in a late-night TV ad framed around the words “tap your home equity when you’ve run out of options.” That framing is wrong for households with substantial assets, and it’s the reason most affluent retirees never look at this tool. They should.
The standby line-of-credit strategy
The wealth-management use case isn’t about needing the money. It’s about what happens during a bear market when you’d otherwise have to sell portfolio assets at the bottom. Selling stocks at a 30% drawdown to cover living expenses permanently impairs the recovery — you took out shares that would have compounded back. This is the sequence-of-returns risk that wrecks retirement plans, and there’s no traditional fix once you’re drawing income.
The standby HECM works like this. At age 62 or later, you open the HECM line of credit while you don’t need it. You let the unused line of credit sit there. Here’s the unintuitive part: the unused line of credit GROWS, at the HECM growth rate (typically expected interest rate plus 0.5% annual mortgage insurance premium — often 6-7% a year). It compounds. So your borrowing capacity at age 80 is much larger than it was at age 62.
When markets sell off, you draw on the LOC instead of liquidating portfolio assets. After markets recover, you resume portfolio withdrawals and can optionally repay the LOC, restoring the borrowing capacity for the next drawdown. The mortgage balance accrues interest only on what you actually borrowed, not on the unused line.
Peer-reviewed work by Sacks & Sacks (2012) in the Journal of Financial Planning, and follow-up research by Salim Lyle at Texas Tech, showed this approach improves portfolio sustainability by 5-10 percentage points across simulated retirement paths. In a sequence-of-returns risk world, that is not a small number.
Why most affluent households haven’t heard of this
Three reasons. First, the consumer-facing marketing for reverse mortgages is dominated by lenders chasing the cash-strapped-retiree segment, who close on the loan immediately rather than letting it sit. Second, the research that legitimized the standby strategy is recent (post-2012) and is still propagating through the advisor world. Third, reverse mortgages still carry the stigma of the pre-2013 program before HUD reformed it to add non-recourse protection, mandatory counseling, and tighter consumer safeguards.
The honest costs — these are not cheap loans
A HECM on a $1.2M home will cost roughly $24,000 in up-front mortgage insurance plus $4,000-$6,000 in origination fees. That’s real money even if it comes out of the principal limit rather than your pocket. The standby strategy is a long-game bet that the optionality you’re buying — a growing line of credit available during market stress — is worth the up-front cost. That bet doesn’t pencil for everyone. Households who would never realistically experience a portfolio crisis (because they have enough fixed income to cover all spending) get less value out of it. The standby HECM is most valuable for households heavily invested in equities where a sequence-of-returns event would force asset sales.
The non-recourse backstop
One feature that surprises most people: HECMs are non-recourse loans. Your heirs are never on the hook for more than the home is worth at the time of sale. If the loan balance has grown to exceed the home value (because markets and time did their thing), FHA insurance — that’s the IMIP you paid up-front — covers the difference. The family’s downside is capped at giving the house back. That structural backstop is what makes the HECM viable as a wealth-management tool rather than just a last resort.
What this calculator does
Enter the youngest borrower’s age (62+ required for eligibility), your home value, any existing mortgage balance that would need to be paid off at closing, and a few assumption knobs. The tool shows you:
- Your principal limit — the maximum the HECM gives you access to
- Closing costs broken out (IMIP, origination, payoff of existing debt)
- Three payment modes side by side: lump sum, monthly tenure, and the standby LOC
- A year-by-year projection of how the LOC grows if you never draw on it
A word on our role: we are not mortgage brokers. T&T Capital Management does not originate or sell reverse mortgages. When this strategy fits a client, we coordinate with HECM-licensed professionals to execute. Every HECM borrower is required by HUD to complete counseling with a HUD-approved housing counselor before closing — that’s a consumer protection we take seriously and support. The calculator is the conversation starter, not the loan estimate.
Run yours.
