Fixed-rate vs adjustable-rate HECM in 1970: which reverse mortgage rate type is right
Last updated: · Reviewed by Simply Approved Mortgages (NMLS #2620881)
Two HECM rate-type choices, two very different products. Fixed-rate HECMs are simple, lump-sum-only loans. Adjustable-rate HECMs are flexible, line-of-credit-capable, and almost always the better choice for borrowers who aren't paying off a large existing mortgage. Here's how to decide.

What is a fixed vs adjustable HECM choice?
A fixed-rate HECM locks a single interest rate for the life of the loan and disburses the entire Principal Limit as a one-time lump sum at closing. There is no line of credit, no growing credit balance, and no option for monthly tenure or term payments. Once funded, the rate never changes — and you cannot draw additional funds later.
An adjustable-rate HECM uses an index (most commonly the 1-year CMT or a HUD-permitted SOFR variant) plus a lender margin to set the note rate. The rate resets per the product's index schedule, subject to HUD-mandated annual and lifetime caps. Adjustable HECMs unlock every HUD payout option: lump sum, line of credit (with monthly growth), tenure payments for life, term payments for a chosen period, or any combination.

| Growing credit line? | Not applicable | Yes — note rate + 0.5% MIP |
| 60% first-year draw rule? | No (full lump sum at closing) | Yes — HUD limit on year-1 draws |
| Lifetime rate cap | Not applicable | Initial rate + 5 percentage points |
| Best for… | Retiring a large existing mortgage in one disbursement | Flexibility, longevity, growing credit line |
When fixed-rate wins: retiring a $200,000 existing mortgage
A 70-year-old with a paid-down home and a $200,000 remaining forward mortgage wants to eliminate the monthly payment. A fixed-rate HECM disburses the full Principal Limit at closing, pays off the existing mortgage, and locks the rate for life — no payment, no rate-reset risk on the accrued balance.

When adjustable wins: a 65-year-old planning for the next 25 years
A 65-year-old with a paid-off home doesn't need a lump sum today — she wants a growing credit line as a longevity hedge. The adjustable-rate HECM opens the line of credit, the unused balance grows every month at the current note rate plus 0.5% MIP, and she only pays interest on what she actually draws. By age 80, the available credit can far exceed what a fresh application at 80 would qualify for.

Expert insight from Simply Approved Mortgages
The fixed-rate HECM is heavily marketed because the lender's compensation on a one-time, full-disbursement loan is larger. For borrowers without a large existing mortgage to retire, that one-time disbursement is also the worst feature — the borrower starts accruing interest on the full Principal Limit from day one and gives up access to the growing line of credit.
We estimate both products on every file and walk through the math. Most borrowers without a mortgage to pay off end up choosing the adjustable-rate HECM with a credit line, exactly because of the flexibility and the growth feature.

Fixed vs adjustable HECM — FAQ
- What's the difference between a fixed-rate and adjustable-rate HECM?
- A fixed-rate HECM has a single interest rate locked for the life of the loan and requires a single lump-sum disbursement at closing — no line of credit, no tenure or term payments. An adjustable-rate HECM has a rate that resets per the underlying index (CMT or certain SOFR rates), and offers lump sum, line of credit, tenure, term, or any combination as payout options.
- Which has lower closing costs?
- Closing costs are essentially the same — the FHA 2% upfront MIP, origination fee, third-party costs, and title charges don't change based on rate type. The big difference is the rate itself and the payout flexibility.
- Can I get a line of credit on a fixed-rate HECM?
- No. By HUD program rule, the line of credit (and its monthly growth feature) is only available on adjustable-rate HECMs. Fixed-rate HECMs are lump-sum only.
- Which has more proceeds at closing?
- Often very close — sometimes fixed has slightly more usable cash at closing because the entire Principal Limit must disburse. On the adjustable, HUD limits first-year mandatory and discretionary draws unless certain conditions are met (the 60% first-year disbursement rule).
- What is the 60% first-year disbursement rule?
- HUD rule on adjustable-rate HECMs: in the first 12 months after closing, the borrower can draw the greater of 60% of the Principal Limit OR mandatory obligations + 10%. The remainder sits in the credit line and becomes available after month 12.
- Is the fixed rate truly fixed?
- Yes — the note rate is fixed for the life of the loan and never changes. The 0.5% annual MIP still applies on top, adding to the accrued balance, but the rate itself is locked.
- What index do adjustable HECMs use?
- Most current adjustable HECMs use the 1-year Constant Maturity Treasury (CMT) index. HUD has also permitted certain SOFR-based indices. The note rate equals the index plus the lender's margin (typically 1.5%–3%).
- Is there a lifetime cap on the adjustable rate?
- Yes — HUD caps adjustable HECMs at 5 percentage points above the initial note rate over the life of the loan. There are also annual caps depending on the specific product.
- Which one should I pick?
- If you need a single large lump sum at closing to pay off an existing mortgage and don't need ongoing access to credit, fixed-rate may fit. If you want a growing line of credit, monthly tenure/term payments, the ability to draw on demand for decades, or flexibility for the unknown, the adjustable-rate HECM is almost always the better tool.
