What Are the Interest Rates on a Reverse Mortgage?

According to HUD HECM mechanics, rate assumptions directly influence both long-term loan growth and the amount of equity a borrower can initially access.

How Reverse Mortgage Interest Works

Unlike a traditional mortgage where you make monthly payments that include principal and interest, a reverse mortgage has no required monthly payment. Instead, interest accrues on the loan balance each month and is added to what you owe. The balance grows over time until the loan is repaid.

This means that even though you never write a check for interest, you are paying it - in the form of reduced equity over time.

A client I worked with in Scottsdale recently saw their projected available proceeds shift by roughly $48,000 between two quote dates, and they said that finally explained why rate timing felt so sensitive. What I find in practice is very different from what most people expect: this is not just a rate conversation, it is a proceeds-and-timeline conversation. After 15 years of doing this in California and Arizona, I can tell you that distinction prevents most planning mistakes.

Fixed vs. Adjustable Interest Rates

Fixed Rate

Fixed-rate reverse mortgages are only available as lump sum payouts on HECM loans. You receive all your funds at closing at a single fixed interest rate that never changes. This provides predictability - you know exactly what rate is accruing from day one.

Adjustable Rate

Most HECM reverse mortgages use an adjustable interest rate, which adjusts based on a published index (typically the 1-year LIBOR or CMT index) plus a margin set by the lender. Adjustable-rate HECMs allow more payout flexibility: monthly payments, line of credit, or a combination.

Adjustable-rate reverse mortgages typically have annual caps on how much the rate can change in a given year and lifetime caps on the total rate increase over the life of the loan.

How Rates Affect How Much You Can Access

Current interest rates directly affect how much equity you can access through a reverse mortgage. When rates are lower, you can typically access more equity. When rates are higher, the amount available decreases.

This is because the lender's calculation accounts for interest that will accrue over the projected life of the loan - and higher rates mean more interest is expected to accrue, reducing the initial available amount.

The Line of Credit Growth Rate

For adjustable-rate HECM line of credit options, the unused line of credit grows over time at the same rate as the loan interest rate (the same rate at which the balance grows). This is one of the most powerful and unique features of the HECM program.

For example, if your line of credit grows at 6% annually and you have $200,000 available but do not draw on it, your available credit will be approximately $212,000 after one year. This growth is guaranteed by FHA and cannot be cancelled by the lender.

Current Rate Environment

Reverse mortgage rates move with the broader interest rate environment. For the most current rates available for your specific situation, the best approach is to request a personalized quote. Rates vary by program, lender, and your individual profile.

Federal Reserve policy updates consistently influence broader mortgage-rate conditions, which is why reverse mortgage quotes should be treated as date-specific rather than evergreen.

Frequently Asked Questions

Are reverse mortgage interest rates higher than regular mortgage rates?

Reverse mortgage rates are generally slightly higher than conventional purchase mortgage rates, reflecting the different risk profile of the product. The comparison also includes FHA mortgage insurance costs for HECM loans.

Does the interest rate affect my heirs?

Yes. The higher the interest rate and the longer the loan term, the larger the loan balance becomes over time - which means less equity remains for heirs when the home is sold. However, the non-recourse protection ensures heirs never owe more than the home's value.

Can I lock in a rate?

For fixed-rate HECM lump sums, the rate is locked at closing. For adjustable-rate programs, the initial rate is set at closing but adjusts over time based on the index.
