The Quick Read: No single program wins for every homeowner. The best fit depends on a few mechanics: whether you pay off the HELOC or keep it, whether the HELOC lender will agree to stay behind a new first mortgage, how the credit line counts toward your total leverage, and what the appraisal says. Everything below walks through those pieces in order.
Key Takeaways
- A new jumbo first mortgage forces a choice on your HELOC: pay it off at closing, or keep it and get written permission from the HELOC lender.
- Leverage is measured against appraised value. An open line can count in full, even when you owe nothing on it.
- Jumbo programs are set by each lender, not by Fannie Mae or Freddie Mac, so agency logic is a guide, not a guarantee.
- The right program depends on your situation. A broker that shops several wholesale lenders can match the file to the program.
What Counts as a Jumbo Loan?
A jumbo loan is a mortgage above the conforming loan limit for your county. Fannie Mae and Freddie Mac can buy conforming loans. They cannot buy jumbos. That is why jumbo programs vary more from lender to lender.
Jumbo cash-out estimate
Enter the value, the balance, and the cash wanted; choose the occupancy and the structure; the lanes, the payment, and the reserves follow.
Editable benchmark: 7.24% as of October 29, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a jumbo cash-out refinance quote.
Illustrative starting assumptions: a $2,000,000 home value in the jumbo range, a $1,000,000 current balance, a principal residence on a thirty-year fixed structure at the current Freddie Mac conforming benchmark, and property taxes and insurance estimated at typical national rates. Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The rate field carries the weekly Freddie Mac thirty-year conforming benchmark, a market reference and not a jumbo cash-out refinance quote; a jumbo loan is priced by the lender at lock. The lanes shown are the wholesale cash-out lanes behind this page as of the snapshot date; the calculator reads each lane’s leverage, loan maximum by occupancy, cash-in-hand cap, and reserves as the lane table states them, and a Lendmire loan officer confirms the lane on the file. The cash available is the loan the lane allows less the balances paid off, before closing costs, which are not included; on most lanes a jumbo cash-out begins one dollar above the conforming limit for the county, and two lanes start at a stated dollar floor instead. The HELOC line is the line program’s combined loan-to-value ceiling applied to the same value and balance. Taxes and insurance are editable estimates. Licensed in sixteen states for consumer mortgages.
The Federal Housing Finance Agency sets the limits each year. Its conforming loan limit announcement describes a baseline limit, plus a higher ceiling in costly counties. The higher limit applies only where 115% of the local median home value exceeds the baseline, and the ceiling is 150% of the baseline. So your county’s number may differ from the national baseline. Check your own county on the FHFA list. The limit is adjusted each year, so any figure you saw last season may be stale.
A jumbo loan begins one dollar above your county’s limit. Everything here assumes you are refinancing the home you live in.
What “Best” Means When You Already Have a HELOC
The best program is the one whose rules fit your file. Nobody can name it without knowing your equity, your HELOC, and your goal for the cash.
Across the wholesale programs Lendmire places files with, a handful of questions separate a good fit from a bad one:
- Subordination policy. Will the program let a HELOC stay in place behind the new first mortgage?
- Cash-out leverage. How high can the new loan plus any remaining line go against value?
- Classification. Does paying off the HELOC count as cash-out, and does it change the leverage cap?
- Reserves. How many months of full payments must you hold afterward?
- Documentation. Does the lane fit how you earn your income?
This is where a broker earns its place. Lendmire’s jumbo cash-out refinance program page outlines the lanes. A broker that shops multiple wholesale lenders can match your situation to the lane built for it, rather than forcing your file into one lender’s box.
Key Terms Defined
Cash-out refinance: A new mortgage larger than the one it replaces, with the difference paid to you.
HELOC: A home equity line of credit, which lets you borrow against your home repeatedly up to a set limit.
Subordination: A written agreement where a junior lender, such as your HELOC lender, agrees to sit behind a new first mortgage.
Combined LTV (CLTV): Loan-to-value counting every loan on the home, not just the first.
Lien: A legal claim on your home that secures a debt.
Payoff letter: A statement from a lender showing what is needed to close out a loan on a given day.
Why Your HELOC Changes the Refinance
Your HELOC is a second mortgage. If you already have a first mortgage, the CFPB explains that a HELOC is paid in addition to it. The HELOC lender holds a claim on your home. A new first mortgage wants to be first in line.
That forces a fork. Either the HELOC gets paid off, or its lender agrees in writing to stay behind the new loan.
Path one: pay it off at closing
The new jumbo first mortgage pays off the old first and the HELOC. The title company sends the money. You then ask the HELOC lender to close the line and record the release. Paying off the balance alone does not close the line. A recorded lien can sit on title until the line is formally closed and released, even at a zero balance. That is practitioner experience, not a rule, but it shows up often enough to plan for.
The payoff comes out of your proceeds. That means less cash to you, and it changes how many programs classify the loan.
Path two: keep it and subordinate
The HELOC stays open behind the new first. Fannie Mae’s subordinate financing job aid calls this a resubordinated lien: the junior lender agrees in writing to sit below the new first.
The HELOC lender does not have to agree. Lenders commonly look at your credit score and your combined leverage. Paying down the balance or reducing the available line can help. Subordination also depends on a third party’s turnaround, so it adds a step you do not control.
| Factor | Pay off at closing | Subordinate and keep |
|---|---|---|
| Net cash to you | Lower, payoff comes from proceeds | Higher, HELOC untouched |
| Lender permission | Not needed beyond payoff | Required in writing |
| Combined leverage | Line is gone | Full line can count |
| Monthly budget | One first-mortgage payment | First plus a variable HELOC payment |
| Process risk | Confirm the release is recorded | Depends on HELOC lender’s response |
| Access to credit | Lost when line closes | Kept |
Does Paying Off the HELOC Make It a Cash-Out Loan?
Often yes, but not in every program. Fannie Mae treats a refinance that pays off a non-purchase-money subordinate lien, including a HELOC, as a full cash-out refinance. Its Selling Guide says so in its disaster-relief guidance. In plain terms: even if you take no cash home, paying off a HELOC that did not buy the house can put you in the cash-out category.
Here is the catch for jumbo borrowers. Jumbo programs are set by each lender, not by Fannie Mae. Many follow agency logic. Some do not. Treat the agency rule as a likely starting point and let the specific program govern.
Cash-out carries lower leverage than a purchase on the jumbo lanes Lendmire works with, and two lanes carry a cash cap on the largest loans. So classification matters. It can decide how much of your equity the program reaches.
A few narrower cases are worth knowing:
- HELOC as the only lien. Then it is a first lien. Freddie Mac’s Guide section 4301.5 lists payoff of a HELOC first lien among the exceptions to cash-out treatment, with conditions. This is rare.
- Free-and-clear homes. Freddie Mac treats a new mortgage on a home previously owned free and clear as cash-out.
- Disaster repairs. Fannie Mae has a narrow flexibility for HELOC draws used for documented disaster repairs. It is agency-only.
- State rules. State law can add its own definitions of cash-out. A local closing agent can tell you what applies where you live.
How the Loan Is Underwritten, Step by Step
Here is the sequence a typical file follows.
1. Pull the liens. The title search shows your first mortgage and the recorded HELOC.
2. Pick the HELOC path. Pay it off or keep it. This decision shapes everything after.
3. Request subordination if keeping it. The HELOC lender decides. Start early.
4. Document your file. Lenders must make a reasonable, good-faith determination that you can repay. The CFPB’s ability-to-repay overview says lenders generally consider and document income, assets, employment, credit history, and monthly expenses. An open HELOC adds a payment to your debt picture.
5. Count combined leverage. Every lien is measured against appraised value. A line’s maximum is set at closing, and many programs count the full limit, not just what you have drawn. Treat that as common practice and confirm it for your program.
6. Order the appraisal. Value is the denominator. A lower value shrinks your proceeds and your room to keep the HELOC. Above a lane’s threshold amount, two appraisals are required.
7. Close. The title company pays off the old liens, records any subordination, and sends you the net proceeds.
The Numbers Behind the Programs
Across the wholesale jumbo lanes Lendmire places files with, the headline lane takes a 660 decision score. Leverage reaches 90% on the highest lane, and several lanes reach 89.99% combined LTV while the rest stop at 80%. Loans reach $5,000,000 on the largest lanes. The ratio ceiling is 50% on the fixed lanes, 45% on the adjustable lanes, and 43% on the interest-only lanes. All of this is subject to lender guidelines and full file review, and none of it is a commitment to lend.
Several things scale up with the loan amount: reserves, measured in months of the full payment, and appraisal requirements. Cash-out leverage sits below purchase leverage. Where cash-out and a keep-the-HELOC plan collide, that lower cap is usually the number that binds first.
One note on myths. The ability-to-repay rule does not hand every lender a fixed debt-to-income cap, and jumbos are not exempt from consumer protections. The CFPB says jumbo loans must meet special requirements to be Qualified Mortgages. Program ratio ceilings come from the lender, not from a single federal number.
A Scenario in Percentages
Picture a homeowner with a home worth a given appraised value. The first mortgage is about 40% of that value. The HELOC has a limit of 15% of value, with about 10% drawn. The homeowner wants cash for a large renovation.
Pay off the line: The new loan covers the old first, the 10% drawn on the HELOC, and costs. The remaining cash is whatever the cash-out cap allows. The line closes, so no unused limit counts against leverage. The new loan might be classed as cash-out, so the cash-out leverage cap applies.
Keep the line: The new loan replaces only the first. The combined leverage now includes the new first plus the HELOC’s full 15% limit. If the program counts the full limit, that 15% eats into the room under the cap, even though only 10% is drawn. The homeowner keeps the credit line, but needs the HELOC lender to subordinate.
Neither path is always better. If the cash need is large and certain, paying off and closing the line often leaves a cleaner file. If the spending is uncertain and the HELOC lender cooperates, keeping the line preserves flexibility, though it keeps a variable payment too. The CFPB’s HELOC guidance notes that payments are often significantly higher once the repayment period starts, and that a lender can freeze a line if home value falls significantly.
Where the General Rule Breaks
- A zero balance does not mean no lien. Until the line is closed and released, it can still sit on title and count toward leverage.
- “The HELOC just stays put” is wrong. It stays only with written subordination.
- Agency cash-out rules are not universal. Jumbo programs write their own.
- Home equity investment liens. These are also junior liens. Refinancing may need that investor’s consent.
- Nearly maxed line. If the line is mostly drawn, payoff is usually the cleaner path, because the balance already weighs on leverage.
- HELOC lender won’t subordinate. Then payoff is the practical route.
Interest deductibility is also a question for your own situation. Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
Which Path Fits You? A Decision Table
| Your situation | Lean toward |
|---|---|
| Large, known cash need | Pay off the HELOC and close it |
| Uncertain spending, cooperative HELOC lender | Subordinate and keep |
| HELOC lender refuses to subordinate | Pay off at closing |
| Line nearly fully drawn | Pay off at closing |
| Large unused line you want to keep | Keep, but check how leverage counts it |
| Existing first mortgage you like | Compare against a second-lien option |
If you like your current first mortgage, a new jumbo cash-out is not the only route.
Common Mistakes
- Paying the HELOC to zero and assuming the line is gone.
- Assuming an unused limit does not count toward leverage.
- Skipping the written release after payoff.
- Applying agency rules to a jumbo program without checking.
- Asking for subordination late, when it can hold up the file.
- Forgetting that the home secures the HELOC. The CFPB’s HELOC booklet warns that the line puts your home at risk.
What to Ask Before You Apply
- Does this program allow a HELOC to remain in place?
- How does it classify a HELOC payoff?
- Does the full credit limit count toward combined leverage?
- What is the cash-out leverage cap, and is there a cash cap on my loan size?
- How many months of reserves does it require?
- Does it need one appraisal or two at my loan amount?
Gather your HELOC statement, a payoff letter if you plan to pay it off, your first mortgage statement, and your income and asset documents before you start.
Frequently Asked Questions
Do I have to pay off my HELOC to do a jumbo cash-out refinance?
No, but you must do one of two things: pay it off or get the HELOC lender’s written agreement to sit behind the new first mortgage. The lender is not obligated to agree. If it declines, payoff at closing is the practical route.
Does an undrawn HELOC still count against me?
It can. Many programs count the full credit limit in combined leverage, not just the drawn balance, and a recorded lien stays on title until the line is closed and released. Confirm how your specific program treats it before you decide.
Will paying off the HELOC turn my refinance into a cash-out loan?
Often, yes. Agency guidelines treat payoff of a non-purchase-money HELOC as cash-out, and many jumbo programs follow similar logic. Each jumbo program sets its own rule, so ask before assuming.
Can the HELOC lender refuse to subordinate?
Yes. Lenders commonly weigh your credit score and combined leverage. Paying down the balance or reducing the line can improve the odds. If the answer is no, you can pay off the line instead.
Is there one best jumbo program for homeowners with a HELOC?
Not for everyone. The best program for your situation depends on your equity, the HELOC’s balance and limit, your credit profile, and how you document income. A broker that shops several wholesale lenders can compare lanes against your file.
If you are weighing a cash-out refinance against keeping the loan you have, Lendmire can help you compare the programs and the equity each one reaches. Lendmire is a mortgage broker, and any program is subject to lender guidelines and full file review.
