A couple who did everything right
David is 71. Karen is 68. By every traditional measure, they planned their retirement well: a $1.4 million investment portfolio, a $1.6 million home with no mortgage, and about $90,000 a year of spending. After their guaranteed income, they need roughly $68,000 a year from the portfolio.
Important: David and Karen are a hypothetical couple. The figures below are an illustrative model, not a real client’s results. But the numbers are conservative by design, and the pattern they show is one I have watched play out in real client files for years.
Four years into retirement, at David’s age 75, the market drops 32 percent. It does not come back quickly. Recovery takes nearly four years. What happens next depends entirely on one decision they made at age 71, before the crash was even a cloud on the horizon.
The two paths
Path A, the default plan: fund every year’s withdrawal by selling shares from the portfolio, the way most retirees are told to. When the crash hits, they keep selling, into a falling market.
Path B, the standby plan: at 71 they open a HECM line of credit on the home with an initial principal limit of about $650,000, and they do not touch it. The line grows about 7.5 percent a year on the unused balance, so by age 75, with zero draws, roughly $868,000 is available. When the crash hits, they stop selling shares entirely. For four years, the line of credit covers the withdrawals. The portfolio sits untouched and recovers with the market.
The year-by-year picture
| Age | Path A: no HECM | Path B: standby HECM |
|---|---|---|
| 75, eve of the crash | $1.35M | $1.35M |
| 76, first full crash year | $867K | $919K |
| 78 | $925K | $1.18M |
| 80 | $906K | $1.31M |
| 85 | $592K | $1.10M |
| 90 | $115K | $748K |
| 95 | Gone | $210K |
Read the two most important rows. At 90, Path A is effectively out of money. Path B still has $748,000. At 95, Path A no longer exists. Path B is still funding their life, with about $210,000 left and a line of credit that still has unused capacity. That is a difference of six or more years of runway, created by a single structural decision made at 71.
Why selling shares during a crash is so expensive
This is sequence-of-returns risk, and it is the most underrated danger in retirement planning. A 32 percent drop at age 40 is a buying opportunity. The same drop at age 75 is a different animal, because the portfolio is simultaneously bleeding from losses and from withdrawals.
Every dollar David and Karen withdrew during the crash under Path A had to come from selling shares that were already down 32 percent. Those shares never got the chance to recover, because they were gone. A withdrawal during a crash permanently converts what would have been a temporary paper loss into a permanent one. Do that for four straight years and the damage compounds for the rest of the plan. That is how a couple with $1.4 million and a 4.8 percent withdrawal rate runs out of money at 90.
Path B simply declined to participate. The shares stayed in the account, the market recovered, and the portfolio that was $1.35 million on the eve of the crash was larger than that again by age 80, even after resuming withdrawals.
What the standby line actually cost
Here is the honest ledger. On a $1.6 million home, opening the HECM line cost roughly $25,000 to $30,000 all-in, the up-front mortgage insurance premium plus origination and standard closing costs, financed into the line so nothing came out of pocket. While the line sits undrawn, there is no monthly payment and the balance does not grow. Once they drew on it, the drawn balance accrued interest plus a 0.5 percent annual mortgage insurance premium, and they drew about $284,000 over the four crash years.
Against that, compare what Path A spent: the entire remaining portfolio after age 90, plus six or more years of retirement income that no longer existed. The line of credit was by far the cheaper insurance policy, and unlike most insurance, its premium sat unused and growing until the exact day they needed it.
The detail that made it work: the line grows while you ignore it
Most people think a reverse mortgage line of credit works like a HELOC: a fixed limit that waits there. A HECM does something better. The unused line grows every year, at roughly the note rate plus the annual mortgage insurance premium. David and Karen’s $650,000 line at 71 became roughly $868,000 by 75 without a single draw. So when the crash arrived, they had more borrowing power than the day they closed, at the exact moment a HELOC lender would have been reviewing their file for a freeze. A HECM line cannot be frozen or reduced by the lender because home values or markets declined. The guarantee is structural, backed by FHA insurance, not by a bank’s quarterly risk appetite.
The rules they still follow
The protection is not unconditional. David and Karen must keep paying property taxes and homeowners insurance, keep the home in reasonable repair, and live in it as their primary residence. If the last remaining borrower moves out permanently or lets taxes and insurance lapse, the loan can become due. And the loan is non-recourse: when the home is eventually sold, if the accrued balance ever exceeds the home’s value, the FHA insurance covers the shortfall and neither they nor their heirs owe a dollar beyond the property. In more than two decades in mortgage banking, I have never seen a HECM borrower’s family receive a bill for a shortfall.
Model it with your own numbers
If you are retired or close to it, the question worth answering is what a crash at the wrong time does to your specific plan, and what a growing, freeze-proof credit line changes about it. The free Perpetual Retirement calculator models exactly this three-scenario comparison, portfolio only, with home equity, and with home equity plus other assets, so you can see your own runway before and after.
Advisors: the same engine powers the Roth Conversion Bridge platform, which models funding Roth conversions from a reverse line of credit instead of portfolio withdrawals. Both tools exist because sequence-of-returns risk is a math problem first and a product conversation second.
The bottom line
David and Karen’s portfolio did not survive the crash because they picked better investments. It survived because at 71 they bought themselves the ability to not sell anything for four years. That is all a standby HECM is: the option to sit out the worst market of your retirement without selling a single share at the bottom. The couple that has that option may never use it. The couple that does not have it never gets the choice.
