Most of the reverse mortgage conversations I have in California focus on monthly payments or a lump sum to eliminate a mortgage. But if you’re under 70, have significant home equity, and aren’t in immediate financial need — the growing line of credit is almost certainly the right structure. I’m Michael DiVita, CA-licensed mortgage broker since 2007, DRE #01818285, NMLS #323700. I work with California seniors on HECM and jumbo reverse mortgages, and the standby line of credit strategy is genuinely the most underused retirement planning tool I encounter.
How the Growing Line of Credit Works
When you establish a HECM reverse mortgage and take proceeds as a line of credit, the unused portion of that credit line grows over time at the same rate as your loan interest — typically 5–7% annually depending on current rates. This means:
- A $400,000 HECM line of credit established at age 67 could grow to $650,000+ by age 77 if left unused
- The growth is guaranteed by FHA — the lender cannot reduce or freeze your line
- You only accrue interest on funds you actually draw
Why This Matters for California Seniors
California homeowners 62–70 often have the most to gain from establishing a HECM line of credit early, even if they don’t need the money immediately. The reasons:
- Hedge against future home value declines: The credit line is set at origination based on today’s home value. Even if your home’s value drops later, your available credit doesn’t.
- Buffer against sequence-of-returns risk: In a down market, drawing from the reverse mortgage line instead of selling investments lets your portfolio recover before you liquidate.
- Tax-efficient retirement income: Proceeds from a reverse mortgage are not income — they don’t affect Social Security taxation thresholds or Medicare premiums (IRMAA).
- Long-term care reserve: The growing line can serve as a tax-free reserve for future care needs — without requiring you to purchase long-term care insurance.
The “Standby” Strategy
A growing number of financial planners recommend establishing a HECM line of credit as a retirement “standby” at 62–65, then not drawing on it for 5–10 years. By the time the homeowner needs it, the available credit has grown substantially — providing a much larger buffer than was initially established. This strategy requires no monthly payments during the standby period (since you’re not drawing) and creates a growing, guaranteed-available credit reserve backed by FHA.
Line of Credit vs. Monthly Payments vs. Lump Sum
| Option | Best For | Key Feature |
|---|---|---|
| Line of Credit | Strategic planning, flexibility | Grows if unused; draw anytime |
| Monthly Payments (Tenure) | Supplementing fixed income | Guaranteed for life |
| Lump Sum | Paying off existing mortgage | Fixed rate available |
| Combination | Income + reserve | Monthly payments + growing credit line |
Frequently Asked Questions
At what age should I establish a reverse mortgage line of credit?
Earlier is generally better for the standby line of credit strategy. At 62 — the minimum HECM age — your initial credit line will be smaller (the younger you are, the lower the principal limit factor), but you have the longest time horizon for it to grow. Many financial planners suggest establishing the line at 62–65 and leaving it untouched for a decade. The tradeoff: a smaller initial line that grows substantially vs. a larger initial line established later with less time to compound.
Can the lender reduce or close my HECM line of credit?
No — this is one of the key advantages of a HECM line of credit over a traditional HELOC. With a HELOC, lenders can freeze or reduce your credit line if home values fall or your financial situation changes. The HECM line of credit is guaranteed by FHA and cannot be reduced, frozen, or canceled by the lender regardless of home values or market conditions.
Does drawing on a reverse mortgage line of credit count as taxable income?
No. Reverse mortgage proceeds — whether drawn as a lump sum, monthly payments, or from a line of credit — are loan advances, not income. They are not subject to income tax and do not count toward Social Security benefit taxation thresholds or Medicare IRMAA premium surcharges. This is one of the most important advantages for California seniors managing retirement income carefully. I always recommend confirming the tax treatment with your CPA or financial planner for your specific situation.
