ARLO explains reverse mortgage line of credit feature

The reverse mortgage line of credit remains the most popular choice among homeowners today—and for good reason.  According to a report by AARP, 66% of borrowers chose the line of credit as the best way to access their reverse mortgage funds.

Why So Many Homeowners Choose the Line of Credit

The reverse mortgage line of credit gives you flexibility and control.  When your loan closes, you can access up to the maximum amount allowed by HUD during the first 12 months.  After that, any remaining funds become available—and you can use them as needed, when needed.

Unlike other loan types, you’re not required to take all your money upfront.  You decide how much to use and when, which helps with long-term financial planning.

So, why do so many borrowers choose this option—even though it’s only offered at an adjustable interest rate?

The Answer: Flexibility

With a line of credit reverse mortgage:

  • You can withdraw funds over time, not all at once.

  • You pay interest only on the money you actually use.

  • The unused funds grow over time, increasing your available credit.

Why Fixed-Rate Reverse Mortgages Are Less Flexible

Some homeowners may consider a fixed-rate reverse mortgage, but it’s important to understand the trade-offs.

Fixed Rate = One-Time Lump Sum

The fixed-rate reverse mortgage only allows for a single lump-sum payout at closing.  There is no line of credit option.  If you need all the funds upfront—like to pay off an existing mortgage—this could work.

But if you want the freedom to access funds later, a fixed-rate reverse mortgage will not meet your needs.

Benefits of a Line of Credit Reverse Mortgage

In contrast, the line of credit gives you several unique benefits:

  • Partial withdrawals at closing, with the rest available over time

  • No interest accrues on the unused portion

  • The line of credit grows monthly based on current rates

  • You’re protected by federal mortgage insurance

Federally Insured Line of Credit = Long-Term Security

The HECM line of credit (Home Equity Conversion Mortgage) comes with a special advantage: it can never be frozen or closed by the lender as long as you meet basic obligations.

Even during market downturns or credit freezes, your line of credit stays in place.  This is not true for traditional HELOCs (home equity lines of credit), which can be reduced or frozen by banks at any time.

You’ve paid for FHA mortgage insurance to guarantee that access to your funds is protected—even when markets shift.

Just remember: You must continue living in your home, pay your property taxes and insurance, and keep the home in reasonably good condition.

Growth Rate Feature

Another significant feature of the line of credit reverse mortgage is the credit line growth rate.

I have often heard this mischaracterized as interest earned, which it is not.  Still, the unused portion of the credit line grows at the same rate at which the loan accrues interest, plus the Mortgage Insurance Premium (MIP) renewal.

How the Reverse Mortgage Line of Credit Grows (Example)

Let’s walk through a simple example to show how your unused funds can grow over time.

Suppose today’s interest rate (known as the fully indexed accrual rate) is 4.25%, and you add the Mortgage Insurance Premium (MIP) renewal rate of 0.50%.  That gives you a total effective growth rate of 4.75% annually.

Now, imagine your available loan amount—after closing costs and calculations—is $350,000.  If you don’t use these funds right away, your line of credit will start growing automatically, month by month.

Here’s what that looks like:

Estimated Line of Credit Growth Over Time

Time PeriodEstimated Credit Line Value
Month 1 Growth$1,385.41
After 5 YearsOver $450,000
After 10 YearsOver $550,000

This growth happens because your available credit increases based on the unused balance and current interest rate.  If you use some of the funds, the growth will adjust accordingly, but as long as there’s a remaining balance, the line continues to grow.

And here’s an added benefit: if interest rates rise in the future, your line of credit grows even faster—helping you hedge against inflation.

Why It’s Better Than a HELOC

A reverse mortgage line of credit shares some features with a traditional Home Equity Line of Credit (HELOC)—but with key advantages:

  • No monthly payments required

  • No lender can freeze or cancel the loan (as long as you continue to live in the home, pay your property taxes and insurance, and maintain the property)

  • Only pay interest on the money you actually borrow

  • Your available credit grows over time—a feature HELOCs don’t offer

Bottom Line

The reverse mortgage line of credit is more than just a way to access home equity—it’s a powerful financial planning tool that grows over time and gives you long-term flexibility.  For many older homeowners, it offers the security and control that traditional loans can’t.

Line of Credit FAQs

Q.

What is a HECM line of credit?

The HECM line of credit is the most popular method of allocating funds to a federally insured home equity conversion mortgage.  The reverse mortgage line of credit is guaranteed for as long as you live in your home and maintain your property taxes and homeowners insurance.  The line of credit is open-ended and revolving, allowing you to advance and repay funds at any time without penalty.  You can make voluntary repayments if you choose or defer interest until you sell your home later.
Q.

Which is better, a home equity line of credit or a reverse mortgage?

The answer depends entirely on your individual needs.  A home equity line of credit, commonly called a HELOC, is a short-term, interest-only loan you can apply for at most major banks.  These equity loans are better suited for those equipped to make monthly repayments and understand that these loans recast after ten years into a balloon note.  Additionally, HELOCs are not guaranteed and can be frozen or reduced at any time due to market volatility or declining property values.  A reverse mortgage line of credit is a loan that works in “reverse” and allows you to borrow money without the burden of mandatory monthly mortgage payments.  A reverse mortgage is guaranteed for as long as you live in the home as your primary residence and maintain your taxes and insurance.  The HECM line of credit can never be frozen or reduced due to market volatility and has the unique feature of any loan program, which is the line of credit growth rate.
Q.

How does a reverse mortgage line of credit grow?

The HECM line of credit comes with a guaranteed growth rate.  The Growth Rate equals your current interest rate + the mortgage insurance rate (currently 0.50% as of February 2025).  Each month, the growth rate is applied to your unused portion of the line of credit.  Growth rate example: Customer has a HECM loan with a $75,000 available unused line of credit.  The hypothetical interest rate of 4%, and a MIP rate of 0.50%.  Each month, the 4.5% combined rate will be applied to the unused line of credit figure. $75,000 x .0450 = $3,375. $3,375/12 = $281.25 in line of credit growth for the next month.  This calculation is performed each month based on how much remains in the line of credit.

Q.

If you already have a reverse mortgage, can you get a Home Equity Line of Credit (HELOC)?

Yes and No.  The federally insured HECM will allow for subordinate financing.  However, finding a lending institution that would go behind a reverse mortgage is difficult due to its negative amortization.
Q.

How is the interest charged on a reverse mortgage line of credit?

The interest is charged on a reverse mortgage monthly and added to the outstanding balance.  The formula for calculating interest is a simple interest formula.  Interest Example: Customer has a HECM loan with an outstanding balance of $50,000 and a hypothetical interest rate of 4%.  $50,000 x 0.040 = $2,000. $2,000/12 = $166.67 in interest added to the loan’s outstanding balance.  Each month, this calculation is performed based on the outstanding loan balance.

Key Takeaways: Why the Reverse Mortgage Line of Credit Stands Out

  • Most Popular Option
    Thanks to its flexibility, the reverse mortgage line of credit is the most commonly chosen payment plan among borrowers.

  • Interest Only on What You Use
    Like a traditional Home Equity Line of Credit (HELOC), you only pay interest on the money you’ve actually borrowed—not on the total available credit.

  • Ideal for Retirees on Fixed Incomes
    With no monthly mortgage payments, no set repayment schedule, and no risk of lender call dates, this option is especially helpful for retirees looking for peace of mind.

  • Built-In Growth Over Time
    Any unused funds in your line of credit continue to grow monthly. This is known as the growth rate, and it gives you more available funds over time—helping you hedge against inflation.
