Whatโs The Only Line of Credit That Increases When You Don't Use It?
Oct 30, 2026
We've Seen This Movie Before
It's the fall of 2008.
Your client's home equity line of credit, the one you both called their emergency reserve, was just frozen. Their portfolio is down sharply. They need $80,000.
Where does it come from?
This isn't a hypothetical (I wish it were). That year Countrywide announced it was reducing or freezing the credit lines of 122,000 borrowers, and JPMorgan Chase, Bank of America and Wells Fargo froze lines too. In 2020 it happened again in a different form: Chase stopped accepting new HELOC applications in April, and Wells Fargo followed in May.
None of this was a scandal. Regulation Z permits a lender to freeze or reduce a HELOC when the home's value declines significantly or the borrower's finances change. The freeze is a feature, not a bug.
Which leaves us with an uncomfortable truth.
Most contingency plans fail at exactly the moment they're needed.
One Sentence, Three Features
There is one tool most advisors have heard of, but few have looked at closely: the line of credit on an adjustable-rate HECM, the FHA-insured reverse mortgage. If you remember one sentence from this article, make it this one:
It's a line of credit that can grow, can't be frozen, and gives your client complete flexibility on payments.
Let's take those one at a time.
Flexibility, not "no payments"
You may have heard that a reverse mortgage has "no payments." That phrase makes careful people nervous, and it should. It sounds like avoiding an obligation.
The better description is flexibility. There is no required monthly principal and interest payment. The client can:
-
Pay nothing, letting interest and mortgage insurance accrue
-
Pay interest only, keeping the balance roughly level
-
Pay down principal, with no prepayment penalty
-
Mix and match by year: pay in high-income years, pause in lean ones
Here's the part most advisors miss. On the adjustable-rate HECM, voluntary payments pay down the loan balance, providing additional availability for future draws.
What doesn't flex: the borrower must keep paying property taxes and insurance, maintain the home, and live in it as a principal residence.
The line grows
The unused portion of the line grows each month at the same rate the loan balance would: the note rate plus the 0.50% annual mortgage insurance premium. Growth doesn't depend on the home's value, so a flat or falling market doesn't slow it.
A quick hypothetical. At a 6.50% note rate, the line grows at about 7.00%. By the Rule of 72, unused capacity would roughly double in a decade if rates held constant. They won't, of course; the rate is variable. But the direction is the point.
One precise note, because your compliance team will be listening for it: this growth is borrowing capacity, not an investment return. The client isn't earning interest.
It can't be frozen
Remember 2008? A HECM line of credit can't be frozen or reduced because the market falls or the home loses value, as long as the borrower meets the loan obligations. It stays available for as long as the loan is in good standing. And it's non-recourse: neither the borrower nor the heirs will owe more than the home is worth.
A HELOC is a convenience. This is a contingency plan.
Said Plainly: What It Is Not
Most articles about reverse mortgages skip this part. I'd rather lead with it. If you're the one naming the costs and limits, you're the trusted resource in the room, not the salesperson.
| It is not... | What that means |
|---|---|
| An investment return | The growth is borrowing capacity. The line isn't an asset, and the client isn't earning interest. |
| Free | A 2% upfront mortgage insurance premium on the home value (up to the 2026 HECM limit of $1,249,125), an origination fee capped at $6,000, and closing costs. |
| Debt-free | Interest and the 0.50% annual insurance premium accrue on whatever is drawn, reducing the equity left to heirs. |
| Obligation-free | Property taxes, insurance and maintenance, and the home must remain the principal residence. |
| Unlimited in year one | Generally 60% of the principal limit (total credit line) is available in the first 12 months, more if needed to pay off existing liens. |
| A solo decision | Independent HUD-approved counseling is required before any application. |
So, the honest question isn't only what it costs to set up the line.
It's what it costs your client not to have the reserve when they need it.
More Clients Than You Think
The line of credit doesn't replace your tools. It gives them a reserve to lean on. Here are seven planning problems you're already solving:
| Planning problem | Where the line helps |
|---|---|
| Sequence-of-returns risk | Draw from the line in down markets instead of selling depressed assets |
| Cash flow longevity | When the plan runs short, an added source of cash flow can extend it |
| Social Security timing | Fund the gap years so the client can claim later |
| Long-term care | A growing reserve for clients who may not be fully covered through insurance, are uninsurable or insurance-averse |
| Cash drag | Hold less idle cash "just in case" and keep more invested |
| Longevity | A reserve that may be larger at 85 than it was at 65 |
| Crisis liquidity | Access that holds when banks pull back, as they did in 2008 and 2020 |
The sequence-of-returns buffer is the most studied of these. Research published in the Journal of Financial Planning found that coordinating a standby line of credit with portfolio withdrawals can improve the sustainability of retirement income, compared with treating home equity as a last resort.
Take thirty seconds. Picture one client who fits at least one row.
Got one? Keep them in mind for the next part.
The Cost of Waiting
Two hypothetical clients. Same $800,000 home, owned free and clear. One decision apart.
Client A opens the line at 62. Client B waits until 72, when the home has grown to about $1,075,000 at 3% a year. Both illustrations use the HUD principal limit factor table at 6.50%, with the line growing at 7.00% (6.50% plus the 0.50% annual premium).
On day one, waiting looks smart. Client B gets a higher factor (think loan-to-value) at 72 (0.393 vs. 0.334) and a more valuable home, so B starts with a bigger line: $391,025 vs. $241,200 when they were 62.
Then compounding does what compounding does.
| Age | Client A (opened at 62) | Client B (waited until 72) | Difference |
|---|---|---|---|
| 72 | $484,730 | $391,025 | $93,705 |
| 77 | $687,166 | $554,326 | $132,840 |
| 82 | $974,144 | $785,827 | $188,317 |
| 87 | $1,380,971 | $1,114,008 | $266,963 |
Client B never catches up. The gap widens every year.
And the table doesn't show the bigger point. From 62 to 72, Client A had a reserve. Client B had a plan (or hope) to get one.
Here's the rub.
The best time to establish the line is when the client doesn't need it.
That's also when it feels least necessary.
Before They Need It
We covered all of this, and more, in our latest Advisor Insights session. It includes the HELOC vs. HECM comparison, the five moments in a client relationship to raise the question, and how firms can bring it to their advisors responsibly.

If a client came to mind as you read, you have two easy next steps. Send us four details (the youngest borrower's age, an approximate home value, any mortgage balance, and the planning concern), and we'll return a complimentary educational illustration. No names needed. Or run the numbers yourself with the HECM Calculator on our website.
No pressure either way. Just one question to sit with.
The question isn't whether your client will ever need liquidity in retirement.
It's whether you'll have arranged it before they do.
Assumptions for the case study: hypothetical clients; HUD HECM Principal Limit Factor table (General Table, ages 62–99) at 6.50%; 7.00% line growth held constant with monthly compounding; no draws; upfront costs of a 2% initial premium on the home value, a $6,000 origination fee and an estimated $4,000 in closing costs. Illustrative only; not a projection or rate guarantee.
