A HELOC is a forward home-equity line with required monthly payments and a bank’s right, in many contracts, to freeze the line. A HECM is a HUD-insured reverse mortgage with no required principal-and-interest coupon, a principal limit from Mortgagee Letter 2017-12 tables, and FHA MIP. Jay Zayer, a CRMP who originates in California and Arizona, compares them as payment-risk tools, not as identical “lines of credit” with different logos.
Age 62, counseling, and occupancy apply to the HECM. A HELOC can go to a 50-year-old who still qualifies on income.
Payments, freezes, and who can cut the line
HELOC payments start as soon as you draw. Underwriting used your income. Retirement can change that income story at renewal or under a hardship clause. A HECM financial assessment can require a LESA, but it does not set a P&I coupon.
Unused HECM credit grows at note rate plus 0.50% annual MIP. A HELOC does not use that HUD growth formula. Some HELOCs offer promotional rates. Those rates end.
Cost stacks that are easy to compare the wrong way
HECM initial MIP is 2.00% of maximum claim amount (Mortgagee Letter 2017-12). Origination is capped by 24 CFR 206.31. Counseling is required (24 CFR 206.41). A HELOC skips MIP and counseling. It adds closing costs of its own and a payment that must clear your retirement budget.
If you can comfortably make a HELOC payment and might pay the line off in a few years, MIP may be the more expensive path. If the payment is the risk, the HECM’s accrual model is the point.
Price both paths with a real payoff and a real monthly HELOC estimate, not a teaser APR.
Which household the comparison actually helps
A 67-year-old in Oro Valley with irregular freelance income and a paid-off house often loses sleep over a HELOC freeze. A 62-year-old still working, planning to sell in three years, may prefer the HELOC’s lower upfront friction. Neither answer is moral. It is payment risk versus MIP.
Suppose the balance you might draw is $40,000 for a roof, and you can pay a HELOC from a pension without strain. That fact pattern can favor the HELOC. The same roof with no spare monthly capacity favors the HECM.
If staying versus selling is the real fork, read reverse mortgage versus selling. If you want HUD’s line-growth mechanic, read how the line grows.
How should you compare the two lines without mixing their rules?
A HELOC is a revolving forward credit line. The bank underwrites income, sets a required payment, and often reserves a contract right to freeze or reduce the line when value or income changes. A HECM line of credit is leftover principal limit on an adjustable HECM after mandatory obligations. HUD rules, not a bank freeze clause, govern unused HECM credit. Unused HECM credit can grow at the note rate plus 0.50% annual MIP (Mortgagee Letter 2017-12). A HELOC does not use that HUD growth formula.
Age 62, counseling under 24 CFR 206.41, and occupancy under 24 CFR 206.39 apply only to the HECM. A 55-year-old with strong income can still hold a HELOC. In California, some proprietary reverse mortgages start at 55. Those are private notes, not HELOCs and not HECMs.
Walk through the arithmetic on a $40,000 roof. A HELOC of $40,000 creates a payment the pension has to clear. A HECM that pays off nothing and draws $40,000 for the roof creates no required P&I coupon, charges 2.00% initial MIP on the full maximum claim amount (not on the $40,000), and starts accrual on the funded amount. If the house is worth $750,000, that initial MIP is $15,000 (hecm-factors.md, 22 September 2026). MIP of $15,000 to fund a $40,000 roof is why a short-horizon HELOC can win. If the payment is the risk, MIP can still be the rational fee.
- Write whether you can make a payment in retirement without strain.
- Write whether you might sell or refinance forward within a few years.
- Write whether a freeze would wreck the plan.
- Price HECM MIP and origination under 24 CFR 206.31 against that horizon.
- If the payment is already the problem, stop shopping HELOC teaser APRs.

Who loses if they pick the wrong line?
A HECM does not help a household that can pay a HELOC comfortably and will sell in three years. They paid MIP for a short stay. A HELOC does not help a household whose income will not support a payment after the last paycheck ends, or whose bank can freeze the line when they most need it.
Here is a situation that comes up often: a 62-year-old still working in the East Bay, planning to sell when a job ends, who was sold a HECM because “no payment” sounded simpler. The simpler file was the HELOC they could qualify for and retire in three years. Jay will say that.
What can go wrong the other way: keeping a HELOC into years when the pension cannot clear the payment, then originating a HECM in a hurry after a missed coupon. That scramble still needs counseling, an appraisal, and a payoff. Starting the HECM conversation before the first missed HELOC payment is cheaper than after it.
If you want to keep a cheap first mortgage and add a junior reverse lien, that is a reverse second, not a HELOC comparison. If proceeds size is the question, use the calculator.
A follow-up: can you hold both a HELOC and a HECM? Only if lien position and underwriting allow it, which usually means the HECM pays the HELOC off or the reverse product is a true second behind a first the senior lender will subordinate. Most standard HECMs wipe the HELOC at closing. Keeping both as a “belt and suspenders” plan is how files die on combined loan-to-value. Pick the payment-risk tool or the MIP tool. Do not stack them as a slogan.
