A first-lien HECM must pay off and close the HELOC. A frozen line is still a recorded lien. 24 CFR 206.36(c) lets you retire a HELOC that does not meet seasoning from borrower funds, HECM funds, or both, if the HECM draw stays inside the 24 CFR 206.25(a) first-year percentage.
Jay Zayer, a Certified Reverse Mortgage Professional licensed in California and Arizona, treats an open HELOC as a release problem, not as a second piggy bank you keep “just in case.” A HECM is FHA-insured. It is not a government benefit and not a way to stack revolving credit behind FHA.
Walk through the arithmetic: suppose a 69-year-old in Glendale, Arizona, has a $420,000 house, no first mortgage, and a HELOC with a $40,000 balance and a $75,000 limit. The HECM principal limit has to cover that $40,000, initial MIP of 2.00% of maximum claim amount (Mortgagee Letter 2017-12), origination under 24 CFR 206.31, and third-party costs. The unused $35,000 of HELOC capacity is not extra room. It is a line that still has to be closed so FHA can sit in first position.
Why does a first-lien HECM close the HELOC even if you never drew it?
HUD underwrites a first-lien HECM as the insured first mortgage. Prior liens that cannot remain are mandatory obligations. A HELOC is a revolving junior or first lien with a recorded credit limit. Even at a zero balance, the instrument is still there. A freeze letter is not a reconveyance.
This is not the HELOC versus HECM product comparison. That page is payment risk versus MIP. This page is what happens to a live HELOC when you originate. It is also not the existing first-mortgage page. A fully amortizing first and a revolving HELOC are different payoff letters.
Request a full payoff-and-close from the HELOC servicer. Ask whether they will reconvey when the balance is zero and the account is closed. Expired payoff letters are how a 30-day refinance becomes a 45-day file. A typical refinance closes in about 30 days. That is an average, not a promise.
California Civil Code section 1923.2(k) still inserts seven days after counseling before a complete application. Arizona skips that statute. Both states still need a live HELOC payoff.
What does 24 CFR 206.36(c) allow when the HELOC is unseasoned?
24 CFR 206.36 is HUD’s seasoning rule for existing non-HECM liens. Subsection (c) is the HELOC sentence. The borrower may pay off a HELOC that does not meet seasoning from borrower funds, HECM funds, or both, so long as the HECM draw does not exceed the first-year percentage in 24 CFR 206.25(a).
That first-year cap is the greater of 60% of principal limit or mandatory obligations plus 10% of principal limit, and it cannot exceed the principal limit (ML 2014-21 / 24 CFR 206.25). Paying off the HELOC is a mandatory obligation. It is not a grocery draw. The 60% rule is not an MIP discount. Initial MIP remains 2.00% of claim amount on every HECM (Mortgagee Letter 2017-12).
If the HELOC is twelve months old or older, seasoning is usually not the argument. The argument is still payoff math. If the HELOC is two months old, 206.36(c) is why the file can still close without a HUD seasoning denial, provided the first-year draw stays legal.
Model the HELOC payoff plus costs at the site’s 7.000% expected-rate assumption as of 22 September 2026. I do not publish a live principal-limit percentage. The 2026 HECM cap is $1,249,125 (Mortgagee Letter 2025-22).
A second geography: a 72-year-old in Stockton with a $180,000 first mortgage and a $55,000 HELOC on a $650,000 house. Both liens have to be satisfied for a first-lien HECM. If the principal limit cannot cover $235,000 plus MIP and costs, the file needs cash in, a principal reduction, a sale, or a different structure. Keeping the HELOC open to “leave a backup line” is how combined loan-to-value dies.
When can a reverse second sit behind something other than a HELOC?
A reverse second sits behind one eligible first mortgage, not behind a first plus an open HELOC. If you want to keep a cheap fully amortizing first, the HELOC still has to be paid and released or the senior lender and the new lender will not have a clean junior slot. Ask that question only after the HELOC is paid and released.
A HECM in third position behind a first and a HELOC is not a standard FHA structure I will originate. Combined liens that already exceed the principal limit do not become eligible because someone likes the HELOC rate.
Cash-out refinance comparisons belong on reverse mortgage versus cash-out refinance. That article is a payment-versus-MIP fork. This page stays on the HELOC release.
What can go wrong: the HELOC servicer freezes the line after retirement, the family treats the freeze as a closing, and title still shows the HELOC. Underwriting will not ignore a recorded instrument. Get the satisfaction.
Who should not keep the HELOC open “just in case”?
This product does not help a household whose HELOC and first mortgage together already exceed the HECM principal limit. Bring cash, sell, or wait for a real HUD cell change. It does not help someone who wants to keep the HELOC open “just in case” after a first-lien HECM. FHA will not share first position with a revolving line you might draw later.
I will not originate a “belt and suspenders” stack. Pick the HECM or keep the HELOC. Do not keep both as a slogan.
A follow-up: can borrower cash pay the HELOC at closing so more HECM capacity stays in a line of credit? Yes. 24 CFR 206.36(c) allows borrower funds, HECM funds, or both. Paying with cash can leave more unused HECM credit, subject to the same first-year cap on whatever you still draw. That is a cash-at-closing choice, not a way to leave the HELOC recorded.
Another follow-up: if the HELOC is in a child’s name on a house the parent occupies, stop. Title and 24 CFR 206.35 have to match the borrower. A child’s HELOC on the parent’s house is a title-and-lien mess, not a seasoning footnote.
I work with multiple lenders. I can compare a first-lien HECM payoff to a reverse second behind an eligible first once the HELOC is gone. I cannot keep your HELOC “just in case” and still deliver a first-lien HECM. Close the line, or do not originate.
