A financial planner in West Lake called me last spring about her parents. Dad was 78, mom was 76, the house was paid off, and the brokerage account had taken a beating in a down market. They needed cash for a roof and a knee replacement, and selling stock at the bottom felt like setting money on fire. She asked me about a reverse mortgage. I told her we could probably make it work, but I also told her the truth: if her parents had opened a HECM line of credit at 62, this conversation would be a five-minute phone call instead of a strategy session.
That is the gap I want to close in this article. Most homeowners meet the reverse mortgage in a crisis. The homeowners who actually win with it open the line years before they need it, and let it grow.
The conventional wisdom that gets it wrong
The reverse mortgage has a reputation problem, and some of it is earned. The product had a rough first generation. Borrowers got sold on it as a way out of a tight spot, the fees were ugly, and the stories that made the news were the stories where it ended badly.
The product today is a different animal. HECM (Home Equity Conversion Mortgage, the FHA-insured reverse mortgage program) is regulated, counseled, and structured in a way that the old product was not. But the cultural memory is sticky. So people still think of it as the move you make when you have run out of moves. That framing is exactly backwards.
The HECM works best when you do not need it yet. The math rewards patience. The strategy rewards planning. By the time you actually need the cash, the best version of the product is no longer available to you.
What the line of credit actually does
Here is the piece almost nobody talks about. A HECM can be structured as a line of credit, and the unused portion of that line grows over time. Not as an investment return. As a contractual feature of the program. The available credit on the line compounds at a rate tied to the note rate plus the ongoing mortgage insurance premium.
In plain English: the older you get, and the longer the line sits unused, the more money you have access to. It is one of the few financial instruments where doing nothing is the strategy.
A few things that flow from that:
- Opening the line earlier (at 62, the minimum age) gives the growth feature more runway
- The growth happens whether home values go up, down, or sideways
- The available credit cannot be frozen or reduced by the lender the way a HELOC can, as long as the borrower meets the occupancy and tax-and-insurance obligations
- You can draw from it, or not draw from it, in any given year, and there is no required monthly payment on what you borrow
That last point is what makes it a planning tool. The HECM line sits alongside the brokerage account, the IRA, the Social Security check, and the pension if there is one. It is another lever. In a year where the market is down, you pull from the line instead of selling equities at a loss. In a year where the market is up, you pull from the brokerage and let the line keep growing.
Why retirement researchers started paying attention
Around a decade ago, academic financial planners (Wade Pfau, Barry Sacks, and others) started running the numbers on what happens when you add a HECM line of credit to a traditional retirement income plan. The results were uncomfortable for the "reverse mortgage is a last resort" crowd. Used as a buffer asset, the line of credit measurably extended portfolio longevity in down-market scenarios.
The mechanism is sequence-of-returns risk. If the first few years of retirement happen to be a bad market, and you are drawing from your portfolio to live, you sell more shares to generate the same income, and the portfolio never recovers. A HECM line gives you somewhere else to pull from in those years. The portfolio gets to heal.
I am not a financial planner. I am a mortgage strategist. But I work with enough planners in Austin to tell you this is the conversation happening at the higher end of the practice. Not "should mom get a reverse mortgage." Instead, "should we open a standby line in her sixties as part of the retirement income plan."
A worked example
Imagine a couple in their early sixties in an Austin neighborhood. The house is worth around $850,000 and the mortgage is paid off. They are both still working part-time, drawing modestly from a $1.2M brokerage account, and waiting until 70 to claim Social Security to maximize the benefit.
They open a HECM line of credit. After closing costs and the initial mortgage insurance premium, the available line is roughly $380,000. They do not draw a dollar. They keep working, keep their cash flow as is, and let the line sit.
Fifteen years later, they are 77. They have not touched the line. Because of the growth feature, the available credit has compounded to somewhere in the range of $700,000 or more, depending on the note rate environment over those fifteen years. The house may be worth more, may be worth less. The line does not care.
Now they have a real menu. Down market year? Pull $60,000 from the line, leave the brokerage alone. Big medical event? The line is there, untouched, no underwriting required. Want to gift a down payment to a grandchild? Same answer.
Contrast that with the version where they ignore the HECM until 78 and a roof emergency. The line opens smaller, has had no time to grow, and the conversation is reactive instead of strategic.
When this fits
- Homeowners aged 62 or older with significant equity and a plan to age in place
- Couples whose retirement income plan is mostly market-based and exposed to sequence risk
- Adult children helping a parent stress-test the next 20 years of cash flow
- Households that want to delay Social Security to 70 and need a bridge for those years
- Anyone whose CPA or financial planner has flagged tax-bracket management as a real concern in retirement
When it does not fit: short time horizons in the home, plans to move within a few years, or households where the equity is genuinely needed for a different purpose like funding assisted living elsewhere.
The honest tradeoff
The HECM has real costs. The upfront mortgage insurance premium is meaningful, the ongoing MIP accrues on the balance, and the loan grows over time rather than amortizing down. If the line gets drawn heavily and the borrower lives a long time, the heirs may inherit a house with little equity left. That is a real conversation to have with the family, and a real conversation to have with a CPA and an estate attorney. The product is a tool, not a free lunch. Used early and strategically, the math tends to work. Used late and desperately, the math is harder.
If you have a parent in their sixties with a paid-off Austin house and no plan for the equity, or if you are that parent, the next step is a real conversation about whether a standby line makes sense for the next twenty years.
