Adjustable Rate Reverse Mortgage: Rates, Payouts, and Costs

An adjustable-rate reverse mortgage is an FHA-insured Home Equity Conversion Mortgage (HECM) for homeowners aged 62 and older, with an interest rate that floats over the life of the loan. Choosing the adjustable version instead of the fixed-rate HECM is what gives you flexible ways to take the money: a line of credit, monthly payments for a set term, monthly payments for as long as you live in the home, or a combination. You make no monthly mortgage payments, and the loan doesn’t come due until you sell, move out, or pass away.¹ Because the loan is federally insured, you or your heirs will never owe more than the home is worth.²

How the Interest Rate Is Built

Your rate has two pieces. The first is a benchmark index that moves with the market. Lenders use either the Secured Overnight Financing Rate (SOFR) or the Constant Maturity Treasury (CMT).³ The second is a fixed margin the lender adds on top, and that margin stays the same for the life of the loan. If SOFR sits at 4.3% and your lender’s margin is 2%, the fully indexed rate is 6.3%. Margins vary and are negotiable, so shopping lenders on margin alone can save real money.

You pick between two reset schedules, each with its own protection:

Annual adjustable: the rate resets once a year. Federal rules cap each annual change at 2 percentage points in either direction, with a lifetime ceiling of 10 percentage points above or below the starting rate.⁴
Monthly adjustable: the rate resets every month. There is no cap on any single monthly change, but a lifetime cap set at origination limits how far the rate can move overall. Monthly resets track the market more closely, so they can also fall faster when rates come down.

One additional safeguard applies to both: the index value used in your calculation can never drop below zero.⁴ Before closing, lenders must also disclose projected total annual loan cost rates at several appreciation scenarios so you can see how different rate environments would affect the cost.⁵

Ways You Can Take the Money

The adjustable rate is the version that unlocks every HECM payment option. Which one fits depends on whether you want steady income, a reserve for later, or both.

Line of Credit

You draw funds when you want them, and interest accrues only on what you actually use. The distinguishing feature is the growth factor: whatever you leave untouched grows at the same rate being charged on the loan balance (index, margin, and insurance premium combined). That growth increases your available borrowing power, not a cash balance you own. Over ten years or more, the unused portion can become substantially larger than the original credit line, which is why some financial planners suggest opening a HECM early and letting the line sit.

Term and Tenure Payments

Term payments send a fixed monthly amount for a set number of months or years. Borrowers often use this to bridge a gap, like covering expenses between retirement and the start of Social Security at 70. Tenure payments work the same way but continue for as long as you live in the home as your primary residence, even if the loan balance eventually exceeds the home’s value. The monthly amount under tenure is smaller than under a term plan drawing from the same balance, because the lender is committing to pay indefinitely.

Splits and Later Changes

You can split available funds between a line of credit and monthly payments. One common setup pairs tenure payments for baseline income with a credit line held back for larger expenses like home repairs or medical bills. If your situation changes, you can restructure the plan later by contacting your servicer. There may be a small administrative fee, but your original choice isn’t permanent.

How Much You Can Borrow

Three factors set your borrowing amount: the age of the youngest borrower (or eligible non-borrowing spouse), the current expected interest rate, and your home’s appraised value. HUD uses these to calculate a principal limit factor, which is a percentage applied to your home’s value or the maximum claim amount, whichever is lower. Younger borrowers and higher interest rates both reduce the percentage. At age 62 with a 5% expected rate, roughly 52% of the home’s value is available; the percentage climbs with age.

For 2026, the national maximum claim amount is $1,249,125. If your home is worth more, the HECM calculation still caps out there.⁶ The limit applies everywhere, including Alaska, Hawaii, Guam, and the U.S. Virgin Islands.

The First-Year Disbursement Limit

Even with an adjustable-rate HECM, you cannot access your full principal limit right away. In the first 12 months, you can draw the greater of 60% of your principal limit or the total of your mandatory obligations (existing mortgage payoff, closing costs, property charge set-asides) plus an additional 10% of the principal limit.⁷ The rule is meant to keep borrowers from draining equity too quickly. After month 12, remaining funds become fully accessible. You lock in that additional 10% election at closing and cannot change it afterward.⁸

What It Costs Upfront

Closing costs follow federally regulated limits, and nearly all of them can be financed into the loan instead of paid from your pocket. The trade-off: financed costs reduce your available proceeds and start accruing interest immediately.

Origination fee. The lender can charge the greater of $2,500 or 2% of the first $200,000 of the maximum claim amount plus 1% of any amount above $200,000, with a hard cap of $6,000. Some lenders advertise lower or waived origination fees, though they may offset that with a higher margin.⁹
Initial mortgage insurance premium. A flat 2% of the maximum claim amount, collected at closing. This funds the FHA insurance that protects both you and the lender.
Ongoing mortgage insurance premium. An annual charge of 0.5% of the outstanding loan balance, added to your balance each month for the life of the loan.
Third-party costs. Appraisals typically run $400 to $700. Title insurance, settlement fees, and recording charges vary by location; HUD requires only that they be reasonable and customary for the area.

Origination fee is where comparison shopping matters most. A lender willing to accept $2,500 instead of $6,000 saves you twice: on the fee itself and on the interest that would have compounded on it.

Who Qualifies

Every borrower on the title must be at least 62.¹⁰ The home must be your primary residence and meet FHA standards for safety and structural soundness. Eligible property types include single-family homes, two-to-four unit buildings where you occupy one unit, and FHA-approved condominiums. Manufactured homes built after June 1976 can also qualify if they sit on a permanent foundation and are classified as real estate.

Before applying, you must complete a session with a HUD-approved counselor.¹¹ The session walks through how the loan works, how the balance grows, and how it affects your estate. The counselor issues a certificate the lender needs before moving forward. The requirement also applies to any non-borrowing spouse and any non-borrowing owner on the title.

The lender then runs a financial assessment covering income, credit history, and residual cash flow. The point is to gauge whether you can keep up with property taxes, homeowner’s insurance, and basic upkeep after closing. Past delinquent property taxes or credit issues don’t automatically disqualify you, but they can trigger a Life Expectancy Set-Aside, described below.

What You Still Have to Do After Closing

A reverse mortgage removes your monthly mortgage payment. It does not remove your other housing costs, and failing on any one of them can put the loan into default.

Live in the Home

The home must remain your primary residence. If you leave for more than six consecutive months for non-medical reasons, the lender can call the loan due and payable.¹² For medical absences, such as a nursing facility stay, the threshold stretches to 12 consecutive months. If another borrower still lives there, one borrower’s departure does not trigger repayment.²

Keep Up Taxes, Insurance, and the Property

You remain responsible for property taxes, homeowner’s insurance, any HOA dues, and reasonable upkeep. Unpaid taxes, lapsed insurance, or a deteriorating property can each independently produce a due-and-payable notice, and if you can’t clear the balance, the lender can foreclose.¹³

Life Expectancy Set-Aside

If the financial assessment raises doubts about your ability to pay property charges, the lender must carve out a Life Expectancy Set-Aside (LESA) from your proceeds. The LESA automatically pays taxes and insurance from HECM funds so those bills don’t go unmet.¹⁴ It also reduces the cash available to you upfront, which can be a significant hit. Borrowers with clean tax and credit histories in the two years before applying are less likely to need one, and even when a LESA isn’t required, you can request one for convenience.

What Happens When the Loan Ends

The full balance, including all accrued interest and insurance premiums, becomes due when the last borrower (or Eligible Non-Borrowing Spouse) dies, permanently moves out, or sells. The process matters as much for your heirs as it does for you.

Heirs receive a due-and-payable notice from the servicer. They have 30 days to decide how to proceed, and the timeline to complete a sale or arrange their own financing can extend up to six months.¹⁵ Heirs who want to keep the property can pay off the balance or refinance into a conventional mortgage. Heirs who don’t want to deal with a sale can use a deed in lieu of foreclosure to hand ownership to the servicer.

If the home is worth less than the loan balance, heirs can satisfy the debt by selling for at least 95% of current appraised value. FHA insurance covers the shortfall, and neither the estate nor the heirs owe the difference.¹⁵ Federal regulations bar the lender from pursuing a deficiency judgment against the borrower; the debt can only be enforced through the property itself.² If the home is worth more than the balance, whatever equity remains after payoff goes to the heirs.

One boundary worth knowing before you sign: if your spouse is under 62 and not on the loan, HUD’s Eligible Non-Borrowing Spouse rules can let them stay in the home after your death, but only if the spouse is properly identified in the loan documents at closing and keeps up taxes, insurance, and occupancy afterward. During that deferral period, no new funds can be drawn from the HECM even though interest continues to accrue on the existing balance.¹⁶
