The Quick Read: It depends on one number: the new first mortgage balance compared with your county’s conforming limit. Both paths replace your first mortgage and your HELOC with a single new first lien. If the total stays at or under the county limit, conforming is usually the simpler lane. If it runs above the limit, jumbo is the lane that fits, with lender-set guidelines instead of agency ones.
Here is the honest version of who each option is for. A conforming cash-out suits the homeowner whose combined payoff (first mortgage, HELOC, closing costs, any extra cash) lands at or below the county limit, and who wants rules published by the agencies. A jumbo cash-out suits the homeowner whose combined payoff lands above that limit, who has solid credit and equity, and who accepts that each lender writes its own rules. Neither is better in the abstract. Size decides the lane, and the cost of giving up your current first mortgage decides whether to refinance at all. Lendmire’s jumbo cash-out refinance program page lays out the jumbo lane in more detail.
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: 7.18% as of November 5, 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.

What Happens When the HELOC Draw Period Ends?
Once the draw period ends, you can no longer borrow, and repayment begins. The CFPB explains that the lender may set a schedule to repay the full balance, often over ten or 20 years, that monthly payments are often significantly higher, and that in some cases the whole amount can be due as soon as repayment begins.
That last point matters most. Many borrowers pay interest only during the draw. When repayment starts, principal comes due as well, and the payment jumps. The federal banking agencies’ guidance calls the result “payment shock.” The FTC adds that a lender can foreclose if you don’t repay as agreed.
Refinancing into a fixed first mortgage swaps a variable, shrinking-window line for a new term. That is the whole appeal. It is also the whole tradeoff, because you give up the terms of your existing first mortgage to do it.

How Does a HELOC Payoff Get Classified?
It is usually a cash-out refinance, not a simple rate-and-term. Under Fannie Mae’s limited cash-out rules, a payoff of an existing subordinate lien counts as limited cash-out only when the proceeds went to the purchase price (or permissible energy expenses). Most HELOCs on a long-held home fail that test, because the money went to renovations, debt, tuition or other spending. A narrow disaster-repair exception exists, but it applies only when the draws followed a disaster and paid for repairs.
That classification affects leverage and pricing. Cash-out caps leave more equity in the home than limited cash-out caps do, and the Fannie Mae Selling Guide notes loan-level price adjustments on certain cash-out refinances, based on leverage and credit score. Jumbo lanes treat cash-out similarly in spirit: lower leverage than a purchase, and on the largest lanes a cap on the cash you can take.
One myth is worth clearing up. The 12-month seasoning test in the Selling Guide applies to the first mortgage being paid off, measured note date to note date. It doesn’t apply to the HELOC. A young HELOC isn’t what blocks a conforming refinance. A recent first mortgage might.
When Conforming Cash-Out Is the Better Fit
Conforming fits when the total new balance stays at or under your county’s limit. The limit changes every year and varies by county, so check the current figure for yours rather than relying on a number from memory. A loan that was jumbo last year may be conforming now, so it is worth rechecking.
Picture a homeowner with a modest first mortgage balance and a HELOC that has run its draw period. Add the two payoffs and estimated closing costs. If the sum clears comfortably under the limit, the conforming lane is open. The rulebook is public, the reserve triggers are written down (the Fannie Mae Eligibility Matrix applies reserve requirements to cash-out files when debt-to-income is above 45%), and the borrower isn’t dependent on one lender’s overlay. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Conforming is also worth a hard look if the total sits just above the limit. Paying the HELOC down before applying can pull the new balance beneath the line. Whether that works depends on what cash you have and whether you’d rather keep it liquid.
The flip point: if you can only get under the limit by draining your emergency savings, the “cheaper” lane may cost you more in resilience than it saves.
When Jumbo Cash-Out Is the Better Fit
Jumbo fits when the combined payoff exceeds the county limit and you’d rather have one first lien than a conforming first plus a separate second. Across the wholesale programs Lendmire places files with, jumbo lanes run from a 660 decision score on the headline lane. That lane’s leverage ceiling is 90% LTV, which measures the first loan alone. Several lanes reach 89.99% CLTV, which counts all liens combined, and the rest stop at 80%. Loans go up to $5,000,000 on the largest lanes. Cash-out sits at lower leverage than purchase, so expect the cash-out limits on any lane to fall below those top figures. Ratio ceilings are 50% on the fixed lanes, 45% on adjustable and 43% on interest-only. Those figures are subject to lender guidelines and full file review.
- Reserves are counted in months of the full payment and rise with the loan amount.
- Above a lane’s threshold amount, two appraisals are typical.
- Fixed, adjustable and interest-only structures exist. The interest-only structure may look familiar to a HELOC borrower, but it brings the same payment-jump question back at the end of the interest-only period.
- Primary, second-home and investment occupancy each carry lane-specific leverage. If the property isn’t your primary home, expect lower leverage.
Jumbo isn’t automatically a worse deal. It simply means above the county limit. Qualification is stricter on the whole, and pricing varies by lender, so comparing more than one program is the point.
The flip point: if your total sits only slightly above the limit, a smaller conforming first mortgage plus a separate second lien can be a legitimate alternative to one jumbo loan. One lien is cleaner. Two liens can be cheaper in some files and costlier in others. It depends on the file.
Does a Straddle Change the Answer?
It can. If the need lands just above the limit, three options exist: pay down the HELOC first, split into a conforming first plus a second lien, or take one jumbo loan. Each option changes how the file is structured, so the choice affects how the refinance is classified and which limits apply.
There is no universal winner.
What Does Switching Cost You?
The central budgeting question isn’t jumbo versus conforming. It’s what you give up. A cash-out replaces your existing first mortgage, so its terms go away along with the HELOC. If your current first mortgage has terms you value, folding in the HELOC may cost more than it saves, and other paths deserve a look. A renewal of the line or a conversion to a fixed balance may also be on offer from your HELOC lender.
Closing costs scale with the loan amount and the lender, and a Loan Estimate will show them before you commit. Terms like “no-closing-cost” simply mean the costs are folded into the balance or built into the pricing, not that they disappear.
If you plan to sell soon, the math changes again. A line has to be paid off when you sell, so a short planned stay can make a full refinance hard to justify.
Timing and the Frozen-Line Risk
Start early. The interagency guidance notes that lines near the end of the draw period may already be frozen or suspended because of declines in collateral value or borrower performance, which can narrow your choices. A balloon-style HELOC leaves a hard deadline, and an appraisal or underwriting delay can run into it. Beginning the conversation while the draw is still open gives you more room to compare options.
Some states also apply special cash-out rules, so state-specific requirements can affect eligibility in addition to the program rules described here.
On the paperwork side, expect the HELOC statement and note, the first mortgage statement and payment history, income and asset documents, and payoff letters for each lien. After closing, confirm the HELOC is closed and the lien released, not just zeroed out.
Key Terms Defined
Draw period: The stretch when you can borrow against the line, often paying interest only.
Repayment period: The stretch after the draw ends when you can’t borrow and must repay principal.
Balloon payment: A lump sum for the whole remaining balance due at the end of a term.
Conforming limit: The county-specific loan size that Fannie Mae and Freddie Mac can buy.
Jumbo loan: A loan above the county conforming limit, set by lender guidelines rather than agency ones.
Cash-out refinance: A new first mortgage that pays off existing liens, including a HELOC not used for the purchase.
A Balanced Verdict
Run the combined payoff against your county limit first. At or under, conforming is usually the more straightforward path and deserves the first look. Above, jumbo is the lane built for it, with the tradeoff of stricter, lender-set guidelines. In the gray zone just over the line, compare pay-down, split-lien and single-jumbo structures instead of assuming one is right.
Then ask the harder question: does giving up your current first mortgage make sense at all? If yes, either lane can retire the HELOC for good. If no, the better move may be renewing, converting or paying down the line instead.
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. Everything above is subject to lender guidelines and full file review, and nothing here is a commitment to lend.
Frequently Asked Questions
Can I pay off my HELOC with a cash-out refinance after the draw period ends?
Yes. A cash-out refinance can pay off the HELOC and your first mortgage together into one new first lien. Because the HELOC usually wasn’t used to buy the home, the payoff is generally classified as cash-out rather than rate-and-term. Eligibility depends on equity, credit, income and the lender’s guidelines.
Does my HELOC have to be a certain age before I refinance it?
No. Fannie Mae’s 12-month test applies to the existing first mortgage being paid off, not to a subordinate lien. A young HELOC isn’t what blocks a conforming refinance, though a recently originated first mortgage can.
What if my total is just above the conforming limit?
You have a few choices: pay the HELOC down before applying, split the financing into a conforming first plus a separate second lien, or take a single jumbo loan. Each has different costs and qualification rules, so comparing them on your actual numbers is the right approach.
Is a jumbo cash-out always harder to get than a conforming one?
Not always, but guidelines are set by each lender and are often stricter on credit, reserves and appraisals. Some jumbo lanes start at a 660 decision score, subject to lender guidelines and full file review. Pricing and terms vary, so a broker comparing more than one program helps.
What happens if I do nothing when the draw period ends?
Repayment begins whether or not you’ve paid down principal, and payments are often significantly higher. Some lines require the full balance at the end. If you can’t make a balloon payment, the home is at risk, so it’s worth planning well before the date.
