Reverse mortgage rates in 1970: how HECM interest, MIP, and the expected rate work
Last updated: · Reviewed by Simply Approved Mortgages (NMLS #2620881)
Reverse mortgage interest rates are quoted two ways — the initial note rate that accrues on your balance, and the expected rate that HUD uses ONCE at closing to calculate your Principal Limit. This 2026 guide explains both, walks through fixed-rate vs adjustable-rate HECMs, the 0.5% annual MIP, the CMT index, and how to read a HECM rate sheet without getting tricked by a low teaser rate.

What is a HECM interest rate?
A reverse mortgage interest rate is quoted as two numbers on every HECM rate sheet: the initial note rate and the expected rate. The initial note rate is the interest that accrues on whatever balance you actually owe — drawn cash, financed closing costs, and prior accrued interest. The expected rate is used once, at case-number assignment, to look up your Principal Limit Factor (PLF) in HUD's PLF table. Lower expected rates produce larger Principal Limits.
Because there is no required monthly principal and interest payment, accrued interest is added to your outstanding balance every month. This is why the loan balance grows over time — and why the difference between a 7.0% rate and a 7.5% rate compounds into a meaningful number over 15+ years.

Fixed-rate HECM vs. adjustable-rate HECM
| Feature | Fixed-rate HECM | Adjustable-rate HECM |
|---|---|---|
| Disbursement | Lump sum only (at closing) | Lump sum, line of credit, monthly payments, or combination |
| Note rate | Locked for life of loan | Resets per the index (typically annually) |
| Line of credit growth | Not available | Unused LOC grows at note rate + 0.5% annual MIP |
| Best for | Paying off a large existing mortgage at closing | Most borrowers — flexibility + longevity hedge |
| Risk | Lock in a higher rate when rates fall | Note rate rises if the index rises |
Benefits of a HECM line-of-credit growth
Cannot be frozen or cancelled
Unlike a HELOC, the lender cannot reduce or freeze your HECM line of credit even if home values fall.
Grows automatically
The unused portion grows monthly at the current note rate plus the 0.5% annual MIP.
Larger borrowing power later
Open early to build the credit line — most retirees need more access in their 80s, not their 60s.
Independent of home appreciation
Growth is driven by the contractual growth rate, not the home's market value.

- Lifetime Cap
- Maximum the adjustable note rate can ever rise above the initial rate (typically 5%). Required by HUD.

Expert insight from Simply Approved Mortgages
The single most common rate mistake we see: borrowers chase a low initial rate without realizing it locks them into a fixed-rate lump-sum HECM with no line-of-credit growth. When rates fall later, they cannot benefit. When they need more proceeds in their late 70s or 80s, there is no growing credit line to draw from.
For most borrowers without a large mortgage to retire at closing, the adjustable-rate HECM with a line of credit beats a fixed-rate HECM by a meaningful margin over a 15-year horizon — even when the initial ARM rate is higher than the fixed rate. The growing credit line is a contractual feature, not a market bet, and it cannot be cancelled.

Reverse mortgage rates FAQ
- What is the current reverse mortgage interest rate?
- HECM rates change weekly and depend on whether you choose fixed-rate or adjustable-rate, the lender's margin, and the underlying index (1-year CMT for most HECMs). Current rates typically sit a few points above 10-year Treasury yields. Ask a licensed reverse mortgage specialist for today's estimate — Simply Approved Mortgages can pull live rates from multiple HUD-approved lenders.
- What is the difference between the initial rate and expected rate?
- The initial rate is the interest charged on your outstanding loan balance right now. The expected rate is a separate long-term rate HUD uses ONCE — at origination — to calculate your Principal Limit using the Principal Limit Factor (PLF) table. Lower expected rates produce larger Principal Limits.
- Is a fixed-rate or adjustable-rate reverse mortgage better?
- Fixed-rate HECMs only allow a single lump-sum disbursement at closing and lock the rate for life. Adjustable-rate HECMs allow lump sum, line of credit, monthly payments, or any combination — and the unused line of credit grows at the note rate plus 0.5% annual MIP. For most borrowers without a large mortgage to pay off, adjustable-rate is more flexible.
- How is reverse mortgage interest calculated?
- Interest accrues monthly on the outstanding loan balance — which includes the cash you have drawn, financed closing costs, mortgage insurance premium, and any prior accrued interest. Because no monthly payment is required, the interest is added to the balance (compounding), which is why the loan grows over time.
- What index is used for adjustable-rate HECMs?
- Most adjustable-rate HECMs use the 1-year Constant Maturity Treasury (CMT) index plus the lender's margin (typically 1.5%–3%). HUD also permits the 1-year and 10-year CMT and certain SOFR-based indexes. The index resets monthly or annually depending on the product.
- Does the mortgage insurance premium count as part of my rate?
- Yes — for purposes of total cost. The ongoing MIP is 0.5% per year on the outstanding balance and is added to your effective interest rate. So an HECM with a 7% note rate has a 7.5% effective accrual rate. The MIP funds the FHA non-recourse guarantee — you and your heirs never owe more than the home is worth.
- Will the rate change my Principal Limit?
- Yes, at origination. Lower expected rates produce higher Principal Limits because HUD's PLF table is built around projected long-term cost of funds. After origination, your Principal Limit does not change — but your line-of-credit growth rate and the interest accruing on drawn balances both move with the index.
- Can I refinance my reverse mortgage if rates drop?
- Yes — a HECM-to-HECM refinance is allowed if it passes HUD's 5x5 benefit rule. The Principal Limit must increase by at least 5x closing costs and new available proceeds must be at least 5% of the new Principal Limit. See our HECM refinance guide for details.
- How do reverse mortgage rates compare to a HELOC?
- HELOC rates are typically lower (prime + small margin) but require qualifying monthly principal and interest payments and can be frozen or reduced by the bank. HECM rates are higher but the line of credit cannot be canceled, the credit line grows over time, and there is no required monthly payment as long as you meet loan obligations.
- How often do reverse mortgage rates change?
- Rate sheets are published weekly by HUD-approved HECM lenders. The expected rate locks at case-number assignment (typically when your application is taken). The initial note rate locks at closing for fixed-rate HECMs; for adjustable-rate HECMs, the note rate resets per the index schedule.
