How does a reverse mortgage line of credit grow, and how can I use it?

How does the line of credit grow?

The unused part of your line grows at the same rate as the loan balance: your loan's interest rate plus the 0.5% annual FHA mortgage insurance premium. It compounds, so the longer you leave it alone, the more it grows. That growth isn't interest paid to you, and it isn't a guarantee of any value; it's more borrowing power available later.

The line of credit comes with the adjustable-rate HECM. The fixed-rate HECM pays one lump sum at closing instead.

What are the three big benefits?

1. It's liquid. Draw what you need, when you need it, with no monthly mortgage payment.
2. Draws aren't taxable income. It's loan money, not income. Confirm your own situation with your tax advisor.
3. It grows. Unused credit grows at the loan's compounding rate, whether or not you ever draw.

How do retirees actually use it?

• Emergency fund: a new roof, a medical bill, or a car without touching savings.
• In-home care: pay for help at home so you can keep living there and leave investments invested.
• A buffer in a down market: when stocks fall, draw from the line for living costs instead of selling investments at a loss. When markets recover, you can pay the line back if you choose, and repaid amounts become available to draw again. This is an advanced strategy, so model it with your financial advisor first.
• Bridge income: cover living costs for a few years so you can delay Social Security or plan other income. See how a reverse mortgage fits retirement taxes.

Why open it early instead of waiting?

Because growth takes time. A line opened at 62 and left alone for 10 or 15 years can offer a lot more borrowing power than the same line opened later. Opening early also means the money is already there when life surprises you, instead of applying when you're under pressure.

What still applies while I have it?

You live in the home as your primary residence, pay property taxes, homeowners insurance, and HOA dues, and keep the home in good repair. Any balance you draw grows with interest and FHA insurance, and it's repaid when the last borrower sells, moves out, or passes away. You can make voluntary payments any time with no prepayment penalty.

Example scenario (illustrative)

A 63-year-old couple in San Diego own their home free and clear and have a solid retirement portfolio. They open a HECM line of credit and don't touch it. Seven years later the market drops 20% in their first year after retiring. Instead of selling investments at a loss, they draw from the line for 18 months of living costs, then pay part of it back once their portfolio recovers.

Our take

This is the part of the reverse mortgage almost nobody knows about, and it's the part I'm most excited to show people. It isn't free money; it's a loan with real costs. But a growing line of credit you never have to use can give a well-planned retirement a lot of peace of mind. I'll show you what your line looks like today, and what it could look like in 10 years, with your real numbers.
