Yes, a reverse mortgage will reduce the equity in your parents' home. That is a mathematical fact. But the question most families actually want answered is: by how much? And the answer, when you run the real numbers, is almost always less dramatic than people fear.
This page shows you the math — no hand-waving, no "it depends," no sales pitch. Real numbers, real assumptions, transparent calculations.
The Scenario
Let us work through a realistic Canadian example:
- Current home value: $750,000
- Reverse mortgage amount: $150,000 (20% of home value — a conservative draw)
- Interest rate: 6.69% fixed (Bloom Finance lifetime fixed rate — middle of the current range)
- Home appreciation: 3% per year (conservative; the Canadian average has been higher historically)
- Compounding: Semi-annual, per the Canadian Interest Act
The Numbers Over Time
Home Value vs. Loan Balance Over 25 Years
$750,000 home, $150,000 loan at 6.7%, 3% annual appreciation
| Year | Home Value | Loan Balance | Remaining Equity | Equity as % of Home |
|---|---|---|---|---|
| 0 (Today) | $750,000 | $150,000 | $600,000 | 80.0% |
| 5 | $869,000 | $209,000 | $660,000 | 75.9% |
| 10 | $1,008,000 | $291,000 | $717,000 | 71.1% |
| 15 | $1,168,000 | $406,000 | $762,000 | 65.2% |
| 20 | $1,354,000 | $566,000 | $788,000 | 58.2% |
| 25 | $1,570,000 | $789,000 | $781,000 | 49.7% |
What This Tells You
After 10 years
The home is worth approximately $1,008,000. The reverse mortgage balance has grown to about $291,000. The remaining equity is $717,000 — which is actually more than the original $600,000 in equity your parents had before taking the reverse mortgage. Home appreciation has more than offset the accumulated interest.
After 20 years
The home is worth approximately $1,354,000. The reverse mortgage balance is about $566,000. The remaining equity is $788,000 — still significantly more than the original equity. Even after 20 years of compounding interest, the estate inherits more than if your parents had never taken the reverse mortgage, assuming the home appreciated at 3% per year.
After 25 years
Even at the 25-year mark — an unusually long period for a reverse mortgage — the remaining equity is approximately $781,000, still above the original $600,000. The loan balance has grown substantially, but so has the home value.
The Key Insight: Appreciation vs. Interest
The entire inheritance question comes down to one comparison: is the home appreciating faster than the loan is growing?
In this scenario, the home appreciates at 3% per year on a base of $750,000 — adding roughly $22,500 in value in the first year. The loan accrues interest at 6.69% on a base of $150,000 — adding roughly $10,000 in interest in the first year. The home's appreciation outpaces the loan's growth by more than 2:1 in the early years.
Over time, as the loan balance grows, the gap narrows. But the home is appreciating on a much larger base ($750,000 and growing) than the loan is compounding on ($150,000 and growing). This mathematical relationship is why, in most realistic Canadian scenarios, the inheritance impact is far less severe than people assume.

What If Home Values Do Not Appreciate at 3%?
Fair question. Here is how the 20-year numbers change at different appreciation rates:
| Appreciation Rate | Home Value at Year 20 | Loan Balance | Remaining Equity |
|---|---|---|---|
| 0% (no growth) | $750,000 | $566,000 | $184,000 |
| 1% | $915,000 | $566,000 | $349,000 |
| 2% | $1,115,000 | $566,000 | $549,000 |
| 3% (our base case) | $1,354,000 | $566,000 | $788,000 |
| 5% | $1,990,000 | $566,000 | $1,424,000 |
Even in the extreme worst case — zero home appreciation for 20 years, something that has never happened over any 20-year period in Canadian real estate — the remaining equity is still $184,000. And remember: the no-negative-equity guarantee ensures the estate can never owe more than the home is worth.
Remaining Equity After 20 Years by Appreciation Rate
$750,000 home, $150,000 loan at 6.69%
Even at 0% appreciation (no growth for 20 years), $190,668 in equity remains. At 3%, equity actually grows above the starting amount.

The No-Negative-Equity Guarantee
All five Canadian reverse mortgage lenders (HomeEquity Bank, Equitable Bank, Bloom Finance, Home Trust, and Fraction) guarantee that the borrower and their estate will never owe more than the fair market value of the home at the time of sale. This means:
- If the loan balance is $400,000 and the home sells for $350,000, the estate owes only $350,000. The lender absorbs the $50,000 difference.
- The estate is never personally liable for any shortfall.
- Other assets in the estate are protected — the lender's claim is limited to the home.
This guarantee is the ultimate safety net. In the worst possible scenario — a prolonged market decline combined with a very long-lived loan — the downside is capped at the value of the home. You cannot inherit a debt.
What About a Larger Loan?
If your parents borrow more — say $300,000 instead of $150,000 — the math changes but the dynamics are the same. Here is the 20-year comparison:
| Initial Loan | Loan at Year 20 | Home Value at Year 20 | Remaining Equity |
|---|---|---|---|
| $100,000 | $377,000 | $1,354,000 | $977,000 |
| $150,000 | $566,000 | $1,354,000 | $788,000 |
| $200,000 | $754,000 | $1,354,000 | $600,000 |
| $300,000 | $1,131,000 | $1,354,000 | $223,000 |
Even with a $300,000 reverse mortgage — 40% of the home's current value — the estate retains $223,000 in equity after 20 years at 3% appreciation. The no-negative-equity guarantee protects against any scenario where the numbers go below zero.
How Loan Size Affects Your Estate After 20 Years
$750,000 home, 3% appreciation, 6.69% interest
Even a $300,000 loan leaves $235,918 in equity after 20 years at 3% appreciation.
The Real Question to Ask
The inheritance question often masks a more important one: what is the alternative?
If your parents do not take a reverse mortgage, what happens? Do they:
- Struggle with monthly expenses and quietly go without things they need?
- Sell the home and downsize — spending $50,000 to $100,000 in transaction costs and uprooting their life?
- Take on a private mortgage at 10%+ with monthly payments they may not be able to afford?
- Ask you or other family members for financial help?
A reverse mortgage costs money — there is no question about that. The interest compounds, and the loan balance grows over time. But the relevant comparison is not "reverse mortgage versus keeping all the equity." It is "reverse mortgage versus the next-best realistic option." And for most retired Canadian homeowners who cannot qualify for conventional lending, the reverse mortgage is often the lowest-cost, lowest-risk way to access their equity. Because reverse mortgage proceeds are tax-free and do not affect OAS, GIS, or CPP benefits, the full amount goes directly to improving your parents' quality of life.
A Note on Fairness
Your parents spent 25 or 30 or 40 years paying off their home. They maintained it, paid the taxes, shovelled the driveway, replaced the roof, survived interest rates of 18% in the 1980s. That equity is theirs. They earned it.
If using some of that equity means they can live comfortably, maintain their independence, cover their healthcare costs, or simply enjoy their retirement without financial stress — that is not "spending your inheritance." That is your parents using their own money for its intended purpose.
The best inheritance is not a bigger cheque. It is parents who lived well.
