Quick Answer
The standby reverse mortgage line of credit is a retirement income tool supported by peer-reviewed research — establishing an unused HECM credit line early, allowing it to grow at approximately 7% annually, and drawing from it only during market drawdowns to avoid selling depressed portfolio assets, which Sacks and Sacks demonstrated in the Journal of Financial Planning produces materially better outcomes than treating home equity as a last resort.
- Establish the line of credit early — the growth rate compounds on the unused balance.
- The credit line grows at the loan's effective rate, approximately 7% in 2026.
- Growth is contractual and independent of home value changes.
- Draw during market drawdowns instead of selling portfolio assets at depressed prices.
- Sacks and Sacks (Journal of Financial Planning, 2012) documented substantially better outcomes with coordinated use.
- The lender cannot freeze or reduce the credit line — unlike a HELOC.

Detailed Explanation
The standby line of credit strategy inverts the traditional advisory view of home equity as a last resort. Under the conventional approach, a retiree draws from their investment portfolio until it is depleted, then considers home equity. Under the coordinated approach, the HECM line of credit is established early — while the borrower is healthy and rates permit favorable terms — and remains unused, growing at the loan's effective rate. When markets decline, the retiree draws from the credit line rather than liquidating portfolio positions at depressed values.
The mechanism that makes this work is the credit line growth feature. The unused portion of a HECM line of credit grows at the same rate the loan accrues — approximately 6.88% to 7.63% in 2026. A $200,000 credit line established at age 65 and left untouched grows to approximately $394,000 by age 75 and $776,000 by age 85. Critically, this growth is contractual and independent of home value. If the home declines in value, the credit line continues growing at the same rate. This makes it structurally different from a HELOC, where the lender retains the right to freeze or reduce the line based on collateral value — a right thousands of banks exercised during the 2008 to 2012 period.
Sacks and Sacks published the foundational research in the Journal of Financial Planning in 2012, modeling retirement portfolios with and without coordinated reverse mortgage use. Their finding — that the coordinated strategy produced substantially larger terminal portfolio values than treating the reverse mortgage as a last resort — has been extended by subsequent work from Wade Pfau at The American College and others. The mechanism is sequence-of-returns risk mitigation: avoiding portfolio withdrawals during the early-retirement drawdowns that permanently impair a portfolio's recovery capacity.
For advisors, the practical implication is timing. The strategy requires the credit line to exist before it is needed, which means the conversation should happen while the client is in their early to mid-sixties, healthy, and not yet in distress. A client who calls their advisor during a 30% market drawdown and asks about a reverse mortgage is 60 days from funding — too late for that particular drawdown. Establishing the line at 65 with no intention of drawing creates the option value that makes the strategy work.

When I meet with a financial advisor for the first time, the standby strategy is usually where the conversation turns. Most advisors have heard the reverse mortgage framed as a desperation product, and the research contradicts that framing directly. What I tell them is: your client does not need to draw a dollar for this to be valuable. Establishing the line at 65 and never touching it until a market event still produces the benefit, because the option value and the growth compound the whole time. I have clients who established lines eight years ago and have never drawn. They sleep better, and their portfolios survived two corrections without a forced sale.
Who This Is Right For
This may be a good fit if:
- CFPs, RIAs, and fee-only advisors evaluating home equity as a component of retirement income planning
- Advisors with clients aged 62 to 70 who own significant home equity and want to understand the coordinated strategy before a market event
This may NOT be the right fit if:
- Advisors whose clients plan to move within two to three years — closing costs are unlikely to be recovered on a short horizon
- Clients with minimal home equity where the resulting credit line would be too small to serve a portfolio protection function
Common Misconception
Myth: The reverse mortgage should be a last resort after other assets are exhausted.
Fact: Peer-reviewed research in the Journal of Financial Planning found the opposite: coordinating reverse mortgage draws with market conditions from the beginning of retirement produces materially better outcomes than treating home equity as a final option.

People Also Ask
Does the reverse mortgage line of credit really grow?
Yes — the unused balance grows at the loan's effective accrual rate, approximately 6.88% to 7.63% in 2026. Growth is contractual and continues regardless of home value changes.
Can the lender reduce or freeze a HECM line of credit?
No. Unlike a HELOC, a HECM credit line cannot be frozen or reduced by the lender as long as the borrower meets their property tax, insurance, and occupancy obligations.
When should an advisor introduce the standby strategy to a client?
Ideally in the client's early to mid-sixties, before any need exists. The strategy depends on the credit line existing before a market event, and funding takes approximately 45 to 65 days.
