When homeowners think about building wealth, they usually think about one thing: home appreciation. It’s true—real estate has been one of the most reliable long-term investments in America.
But there’s another asset that often gets overlooked: a reverse mortgage line of credit.
What surprises many homeowners is that an unused Home Equity Conversion Mortgage (HECM) line of credit doesn’t stay the same size. It grows over time, creating additional borrowing capacity without requiring monthly mortgage payments.*
So how does that compare to the growth of home values?
Home Appreciation: The Traditional Wealth Builder
According to long-term national housing data, U.S. home values have averaged approximately 4% annual appreciation over time.
Imagine a home worth $600,000 today.
At a 4% annual appreciation rate:
- After 5 years: about $730,000
- After 10 years: about $888,000
- After 15 years: about $1.08 million
That’s impressive growth and one of the reasons many retirees have accumulated substantial home equity.
The Hidden Advantage: A Growing Line of Credit
Here’s where many people are surprised.
With an adjustable-rate FHA HECM, any unused line of credit grows over time. Instead of staying fixed, your available borrowing power increases each month—even if your home’s value doesn’t.
Suppose you establish a $250,000 line of credit and never draw from it.
If the line grows at approximately 6% annually (growth depends on the loan’s applicable interest rate and mortgage insurance premium), the available credit could grow to roughly:
- After 5 years: $335,000
- After 10 years: $448,000
- After 15 years: $598,000
Unlike a traditional HELOC, you’re not required to requalify based on income, employment, or credit simply because your available credit has increased.
Which Grows Faster?
Home Value
- Starts at: $600,000
- Grows at: 4% annually
Unused HECM Line of Credit
- Starts at: $250,000
- Grows based on the loan’s applicable growth rate
In many interest-rate environments, the line of credit may grow faster than national average home appreciation.
That doesn’t mean your home’s value is increasing faster or slower—it simply means your available borrowing power may expand at a different pace.
Why This Matters in Retirement
Many retirees never intend to use their line of credit immediately.
Instead, they establish it while they qualify and allow it to grow for future needs, such as:
- Healthcare expenses
- Home renovations
- Long-term care planning
- Helping family members
- Creating an emergency reserve
- Managing retirement income during market downturns
Having access to a larger line years later can provide flexibility when financial needs change.
The Bottom Line
Home appreciation helps grow your wealth.
A HECM line of credit has the potential to grow your available borrowing capacity.
They’re two different forms of growth—but together they can become powerful retirement planning tools.
Rather than choosing one or the other, many homeowners view a growing line of credit as a way to complement the wealth they’ve already built through decades of homeownership.
*An FHA Home Equity Conversion Mortgage (HECM) line of credit is available only with eligible adjustable-rate HECM loans. The available line of credit grows over time based on the loan’s applicable interest rate plus the annual mortgage insurance premium, as established under FHA program rules. Growth rates are not guaranteed and will vary over time. Home appreciation is not guaranteed, and the 4% figure represents a long-term national average rather than future performance. Borrowers remain responsible for paying property taxes, homeowner’s insurance, maintaining the home, and complying with all loan terms.
