HECM line of credit in 2026: the growing credit line that cannot be cancelled
Last updated: · Reviewed by Simply Approved Mortgages (NMLS #2620881)
The HECM line of credit is the single most powerful — and most misunderstood — feature of a reverse mortgage. The unused balance grows every month at the note rate plus the 0.5% annual MIP, the lender cannot freeze or cancel it, and you only pay interest on what you actually draw. This 2026 guide explains how the growth math works, why opening early matters, and how the credit line compares to a HELOC.

What is a HECM line of credit?
A HECM line of credit is a federally insured, growing credit line built into an adjustable-rate Home Equity Conversion Mortgage. After closing, the portion of your Principal Limit that you have not drawn sits in an available credit line. Each month, the unused balance grows at the current note rate plus the 0.5% annual mortgage insurance premium — and you only owe interest on the portion you actually withdraw.
The growth rate is contractual, not a market promise. It happens whether home values rise or fall, whether the stock market crashes or booms, and whether the lender wants to keep the line open or not — they have no authority to cancel it under HUD's HECM rules.

HECM line of credit vs HELOC
| Feature | HECM line of credit | HELOC |
|---|---|---|
| Can the lender cancel or freeze it? | No — federally protected | Yes — happens in downturns |
| Does the unused balance grow? | Yes — note rate + 0.5% annual MIP | No |
| Required monthly payment | None (borrower must still pay property taxes, homeowners insurance, HOA dues, and maintenance) | Interest-only during draw, then P&I |
| Minimum age | 62 | 18+ |
| Credit qualification | Financial assessment only | Full credit + income underwriting |
| Draw period | Lifetime — as long as you live in home | Typically 10 years |
| Rate type | Adjustable (CMT + margin) | Variable (Prime + margin) |
Benefits of a HECM line of credit
Cannot be cancelled or frozen
Even in a 2008-style housing crash, HUD's HECM line stays open. HELOCs get frozen first.
Grows automatically
The unused balance grows monthly at the current note rate + 0.5% MIP — every year you wait to use it, the credit line gets bigger.
Only pay interest on what you draw
Interest does not accrue on the unused portion. You can sit on a $300,000 credit line for 10 years without accruing a penny of interest.
Tax-advantaged draws
Draws are loan proceeds, not income — generally not considered taxable income and do not affect Social Security or Medicare.
Longevity hedge
Most retirees need MORE access in their 80s, not their 60s. The growing credit line is built for that.
Revolving — repaid amounts restore
Voluntary repayments on the HECM reduce the outstanding balance and typically restore to available credit (no HECM prepayment penalty; your servicer may charge a small payoff-statement fee).
The math: opening at 62 vs waiting until 75
Two homeowners, same $500,000 paid-off home. Borrower A opens an adjustable-rate HECM at 62 with an initial credit line of roughly $190,000 and draws nothing. Borrower B waits until 75 to apply.
Illustrative example (assumes a hypothetical 7% note rate — actual rates and APR vary daily): at a 7% note rate + 0.5% MIP = 7.5% growth rate, Borrower A's credit line at age 75 has grown to roughly $485,000. Borrower B, applying fresh at 75, qualifies for a Principal Limit of roughly $280,000–$310,000 (higher PLF at older age, but no compounded growth). APR is federally disclosed at closing and is typically 1–2 percentage points above the note rate.
Borrower A has $175,000+ more borrowing capacity at age 75 — without paying a penny of interest, because none of the credit line was drawn. This is the single most important reason to consider opening a HECM line of credit early and letting it grow.

Illustrative example only. Actual figures depend on age, home value, current expected rate, and HUD lending limits at closing.
How the growth actually works — and what it is not
The math is simple: your available line of credit equals your current principal limit minus your unpaid loan balance. Each month, the unused portion is increased by the current note rate plus the 0.50% annual ongoing mortgage insurance premium, compounding. (0.50% is the current ongoing MIP rate; HECMs originated under older HUD rules may carry 1.25%.)
It matters how this is described. The growth is a greater capacity to borrow more money in the future, regardless of home value — it is not income, not interest paid to you, not earnings, and not a return on your home equity. It is also not guaranteed in every circumstance: a line that has been fully drawn has nothing left to grow, and growth pauses during a non-borrowing-spouse deferral period.
Prepayments and redraws
Voluntary prepayments are allowed at any time with no HECM prepayment penalty, and they increase your available credit dollar for dollar. If you make a $5,000 prepayment, your loan balance drops by $5,000 and your available line of credit rises by $5,000.
Payments are applied in a set order: mortgage insurance first, then servicing fees, then accrued interest, then principal. If you want to keep the HECM and its line of credit open, pay the balance down to a small minimum balance (about $100) rather than to zero — HUD's system of record can close the loan once the balance falls below $100. Prepayments over $600 in a calendar year are generally reported on IRS Form 1098 the following January; consult your tax advisor about deductibility.

Expert insight from Simply Approved Mortgages
The HECM line of credit is the closest thing in the U.S. financial system to a contract that pays you to wait. The lender literally cannot take it away, the unused portion grows at a rate that beats most short-term Treasury yields, and you only pay interest when you actually need the money.
Yet most TV-advertised reverse mortgages push the fixed-rate lump sum — because it pays the lender a larger origination commission. For most borrowers without a large existing mortgage to retire at closing, the adjustable-rate HECM with a growing line of credit is the better product by a wide margin.

HECM line of credit — FAQ
- What is a HECM line of credit?
- A HECM line of credit is one of the payout options on an adjustable-rate Home Equity Conversion Mortgage. The unused portion of your Principal Limit sits in a credit line you can draw from any time — and the unused balance grows monthly at the current note rate plus the 0.5% annual MIP.
- How does the HECM line of credit grow?
- Each month, the unused credit-line balance is multiplied by (note rate + 0.5% MIP) ÷ 12. That growth is added to the available credit line. Over 15 years, a credit line opened in your early 60s can more than double — a powerful longevity hedge even if home prices stay flat or fall.
- Can the lender cancel or freeze my HECM line of credit?
- No. Unlike a HELOC, a HUD-insured HECM line of credit cannot be frozen, reduced, or cancelled by the lender — even if home values fall or interest rates rise. The growth and availability are contractual and federally backed.
- When should I open a HECM line of credit?
- The earlier the better — within HUD's eligibility rules (age 62+). The credit line grows at the same rate whether you use it or not, so opening at 62 and not drawing until 75 produces a substantially larger borrowing capacity than waiting until 75 to apply.
- Do I pay interest on the unused line of credit?
- No. Interest only accrues on the portion of the credit line you have actually drawn. The unused balance grows at the growth rate but does NOT accumulate interest until drawn.
- Is the HECM line of credit better than a HELOC?
- For most seniors, yes — the HECM line cannot be cancelled, grows automatically, and has no required monthly payment as long as you meet your loan obligations. A HELOC has lower rates but requires monthly payments, can be frozen, and ends after the draw period. HELOCs are better only for short-term borrowing.
- Can I pay back what I draw from the credit line?
- Yes. There is no prepayment penalty on a HECM. Voluntary payments reduce the outstanding balance, and the repaid amount typically restores to your available credit line (it's revolving).
- What if interest rates rise — does my credit line still grow?
- Yes, and it grows faster. The growth rate is the current note rate (which moves with the index) plus the 0.5% annual MIP. Rising rates accelerate credit-line growth — one of the few financial products where rising rates help the borrower.
- How is the HECM line of credit different from the tenure payment?
- A tenure payment converts your Principal Limit into equal monthly payments for as long as you live in the home as your principal residence. The line of credit leaves the funds in a growing credit line you draw from on demand. Most borrowers blend the two — partial tenure for predictable income, the rest in the credit line for flexibility.
- Is the HECM line of credit available on fixed-rate HECMs?
- No. The line-of-credit feature (and its growth) is only available on adjustable-rate HECMs. Fixed-rate HECMs require a single lump-sum disbursement at closing with no credit line. This is the main reason most borrowers without a large mortgage to retire choose the adjustable-rate HECM.

Why we pull credit for your reverse mortgage pre-approval
HUD requires a Financial Assessment for every HECM reverse mortgage, including a review of your credit history and record of paying property taxes and homeowners insurance. As part of our standard broker/lender pre-approval process, we typically order a tri-merge credit report through a HUD-approved credit vendor to verify identity, review obligations, and confirm that you can continue paying property taxes, homeowners insurance, and maintenance after closing. Whether a tri-merge is required, and any fees, are set by the wholesale lender and credit vendor — not by HUD as a stand-alone rule.
Pay for your credit report — SmartPay
Simply Approved Mortgages uses MeridianLink SmartPay to securely collect the credit report fee for your reverse mortgage pre-approval. Payment goes directly to the credit vendor — not to us — and unlocks a tri-merge credit report (Equifax, Experian, TransUnion) that your loan officer uses to complete the broker/lender pre-approval file for HUD's Financial Assessment.
