The assumption is that taking out a reverse mortgage shrinks your estate — less house equity means less for your heirs. The reality is more interesting. For retirees with substantial retirement assets, drawing on home equity strategically often preserves MORE generational wealth than leaving the equity untouched. Here's why, with real numbers.
The intuition is backwards because of taxes
If you have $1.5M in a traditional IRA and a $1.5M paid-off home, your kids will inherit very different versions of those assets:
- The IRA is fully taxable to your heirs as ordinary income. In a 32% federal + 9.3% California bracket, your kids receive roughly $880,000 from a $1.5M IRA after taxes. Most heirs have 10 years to withdraw it (SECURE Act).
- The home passes with a stepped-up basis to fair market value. Heirs can sell it with no capital gains tax. They receive roughly $1.5M minus closing costs.
The home is the tax-efficient asset. The IRA is the tax-inefficient asset. If you need to spend down one of them during retirement to maintain your lifestyle, drawing on the IRA shrinks the better-treated asset for your heirs.
How reverse changes the math
A reverse mortgage line of credit lets you draw on home equity in tax-free dollars during retirement. Instead of pulling $80,000 from your IRA (which costs you closer to $115,000 pre-tax in a typical bracket), you draw $80,000 from the reverse line and let the IRA continue compounding.
The reverse loan balance grows over time at interest. The IRA grows over time at market returns. If market returns exceed loan interest (a reasonable long-run expectation), your net estate value grows faster than if you'd drawn from the IRA.
A real scenario
Robert and Anne are 72 and 70. They have $2M in retirement accounts and a $1.6M Dana Point home, paid off. They need to draw $100,000/year on top of Social Security to maintain their lifestyle.
- Strategy A — Draw all from IRA. Over 15 years they pull $1.5M+ from the IRA (gross, accounting for taxes). The remaining IRA at age 87 is approximately $1.2M (assuming 6% returns). The home is unchanged at, say, $2.4M after appreciation. Net estate: $3.6M.
- Strategy B — Reverse line of credit for half. They draw $50K/year from the IRA and $50K/year from the reverse line. The IRA grows more (because they pull less from it). After 15 years the IRA is approximately $1.9M, the home is $2.4M, the reverse balance is approximately $1.1M. Net estate (home equity + IRA): $3.2M from the home + $1.9M from the IRA = approximately $4.0M, minus the loan payoff = $3.2M net.
The difference depends heavily on returns and rates — in this example Strategy A actually wins narrowly, but if market returns outpace loan rate by 1 percentage point or more, Strategy B catches up and surpasses. The point isn't that reverse is always better. The point is that the comparison is far less obvious than instinct suggests, and worth modeling for your specific situation.
The conversation to have
Bring this to your financial advisor. Bring your CPA. Run the actual numbers against your portfolio mix, your rate sensitivity, your time horizon. We've published a Cash Flow Planner template that walks through the comparison; download it from the resources section.
For families with substantial retirement assets where heirs would inherit a sizable IRA, the legacy-planning angle is sometimes the single biggest reason to take a reverse — not for the cash flow, but for the tax efficiency of the estate at the end. That's a conversation worth 30 minutes.
