The Quick Read: The best program for your situation depends on one question: does the second mortgage stay or get paid off? Paying it off inside a cash-out refinance is the simplest path for most homeowners. Keeping it requires the second lender’s written agreement. Across the wholesale programs Lendmire places files with, conventional cash-out on a one-unit primary residence generally tops out at 80% loan-to-value, subject to lender guidelines and full file review.
How a Second Mortgage Changes Your Cash-Out Refinance
A second mortgage sits behind your first loan in line to be repaid. When you refinance the first loan, the old one is paid off and a new one takes its place. That new first loan wants the top spot. So the second lender has to either be paid off or agree to stay behind the new loan.
Cash-out refinance estimate
The starting figures are an example value with a balance and a cash request in proportion. Replace them with yours.
Editable benchmark: 7.24% as of October 29, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a cash-out refinance quote.
Illustrative starting assumptions: a $350,000 home value, a $193,000 current balance, the agency cap on a one-unit principal residence, a thirty-year term at the current Freddie Mac 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 conventional benchmark, a market reference and not a cash-out refinance quote; a cash-out loan is priced by the lender at lock. The cash available is the loan the program cap allows less the balances paid off, before closing costs, which are not included. The HELOC line is the 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.
Loan-to-value (LTV) is your loan balance divided by your home’s appraised value. A home equity line of credit (HELOC) is the most common second lien. Some lenders count the full credit limit, not just what you have drawn. Hold that thought, because it shrinks your cash faster than most people expect.
A cash-out refinance, in plain terms, is a larger mortgage that pays off the current one and hands you the difference in cash. The Fannie Mae Selling Guide lists paying off subordinate liens as an acceptable use of those funds.
Key Terms Defined
Second mortgage: a loan secured by your home that ranks behind your first mortgage, such as a HELOC or home equity loan.
Subordination (resubordination): a signed agreement where the second lender agrees to stay behind your new first mortgage.
Purchase-money second: a second loan taken at the time you bought the home to help fund the purchase.
Combined LTV: the first and second mortgage balances together, divided by the home’s value.
Seasoning: the minimum time a loan or ownership has been in place before a refinance is allowed.
Limited cash-out (rate-and-term) refinance: a refinance that pays off the first mortgage and closing costs, with only small cash back.
What Are Your Three Paths?
You have three real choices. Each trades cash, difficulty, and paperwork differently.
| Path | What happens | Cash to you | Who must sign |
|---|---|---|---|
| Pay off the second | Cash-out loan retires both liens | Reduced by the payoff | Only you |
| Keep the second | New first loan, second stays | Limited by combined LTV | Second lender |
| Skip the refinance | Leave both loans alone | None | No one |
Paying off the second is usually the cleanest. One new loan replaces two, and nobody else has to approve anything. Keeping the second makes sense when its terms are better than anything you could get today. But it only works if that second lender agrees to resubordinate, and a lender can refuse.
Does Paying Off the Second Make It a Cash-Out Refinance?
It depends on how the second loan began. The answer drives which program you land in.
If the second was a purchase-money loan, both Fannie Mae and Freddie Mac allow a limited cash-out refinance to pay it off. Freddie Mac’s guide asks for documentation that the paid-off lien funded the purchase. Your settlement statement or title policy usually does the job.
If the second was a HELOC or home equity loan used for anything else, paying it off makes the new loan a cash-out refinance. That holds even if you take no extra cash. The Fannie Mae Selling Guide on limited cash-out refinances draws that same line.
Why does it matter? Limited cash-out allows up to 95% LTV on a one-unit primary residence across the programs Lendmire works with. Full cash-out caps at 80%. That gap is the difference between a smooth file and a short one. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
How Is a Cash-Out Refinance With a Second Mortgage Underwritten?
Underwriting follows a set order. Here is what the lender checks, step by step.
1. Classify the second lien. Purchase-money or not? This sets the loan type.
2. Decide: pay off or keep. Keeping it triggers a resubordination request to the second lender.
3. Run combined leverage. First loan, second loan, and any HELOC limit are tested against the cash-out ceiling. A second you keep uses up room you would otherwise take as cash.
4. Order the appraisal. Value feeds every ratio. A higher value helps, a lower one can sink the plan.
5. Check seasoning. The first mortgage being paid off must be at least 12 months old, counted note date to note date. The same Fannie Mae section says that rule does not apply to subordinate liens being paid off. You also need to have been on title for 6 months, with exceptions for delayed financing, inheritance, and legal awards.
6. Verify credit and income. Wholesale conventional programs generally start at a 620 decision score, and automated findings govern most files, with a total debt ratio ceiling of 50%. Manually underwritten loans use tighter ratios of 36% or 45%.
7. Document the file. Expect payoff statements, proof the second was purchase-money if that applies, and a signed, recorded resubordination agreement if the second stays.
Every figure here is a guideline, not a promise. Lender overlays vary, and nothing is a commitment to lend.
What Does the Math Look Like in Practice?
Skip dollar amounts and think in percentages. Say your home appraises at 100% of its value. Your first mortgage is 45% of that value, and a HELOC balance is 15%. Together that is 60% combined.
A conventional cash-out on a one-unit primary residence reaches 80%. If you pay off both liens, your new loan can go to 80% and your gross cash is the gap above the 60% you owe. Roughly 20% of value, before closing costs.
Now keep the HELOC instead. The new first loan plus that 15% second must still fit under the same ceiling. The new first can only reach about 65%, but paying off only the old first (45%) leaves you the same 20% gap, so the HELOC does not add cash; it only keeps the second lien in place. And if the HELOC has a large unused limit, a lender counting the full line may treat it as more than 15%, which can shrink the new first loan further.
That is the net-cash trap. The headline loan amount is not your check. Subtract the payoffs and closing costs first.
Which Programs Fit Which Borrower?
There is no single winner. The best program for your situation follows from your loan type, property, and goal.
- Conventional cash-out, primary residence. 80% LTV on a one-unit home. Two- to four-unit primary homes, second homes, and investment properties sit at 75%. This is the default for most homeowners with a second to retire.
- Higher-leverage wholesale lane. One lane reaches 89.99% LTV with no mortgage insurance. It needs a 680 score, a 50% ratio, a thirty-year fixed rate, a primary residence, a conforming balance, and its own six months of seasoning. It can fit a borrower with strong credit who needs more room, but it is narrow. It is not written on Texas homesteads, where the state constitution caps cash-out at the agency figure.
- Jumbo. Above the conforming limit, jumbo lanes take over. They generally need a 660 decision score, reach up to 90% leverage, and handle loans to $5,000,000, with a 50% ratio ceiling on fixed lanes.
- FHA and VA. If your existing loan is FHA-insured, the FHA Streamline is built for lowering costs, not extracting equity. HUD’s streamline page limits cash back to $500 and bars rolling in closing costs. The VA IRRRL works the same way for VA loans: it replaces only the existing VA loan and cannot pay off other liens, per VA Pamphlet 26-7. A VA cash-out can refinance any type of lien, including a second mortgage.
Which lenders write each lane depends on your credit profile, equity, property type, and documentation. That is why a broker who shops several wholesale lenders matters here. Lendmire’s cash-out refinance programs page lays out the options Lendmire arranges as a broker, never as the lender.
What If the Second Lender Says No?
Resubordination is the second lender’s call. They are being asked to move from a safe position to a riskier one. Some refuse, especially when combined leverage is high.
You have a fallback ladder:
1. Pay off the second inside a cash-out refinance. This removes the lender’s veto.
2. Change programs. A different loan type may handle the lien differently.
3. Reduce the second first. Paying down a HELOC improves combined leverage and may soften the lender’s stance.
4. Wait. Leave things as they are until equity or the lender’s position changes.
Subordination adds steps to the file. Start the request early and run it alongside the appraisal.
Where the General Rules Break
- Purchase-money seconds. These are the exception that lets a limited cash-out pay off a second without triggering full cash-out treatment.
- State law. Fannie Mae waives the resubordination agreement only where state law keeps the second in its junior position.
- Affordable second programs. Narrow carve-outs let a community or affordable second sit behind a high-leverage limited cash-out. They apply to specific programs, not to ordinary HELOCs.
- Manufactured housing. Single-width manufactured homes have been ineligible for cash-out under Fannie Mae’s product matrix.
- Occupancy. A second home or rental carries lower cash-out leverage than your primary residence. Occupancy decides the ceiling.
- Old programs. RefiNow is closed. Ignore any page that still presents it as available.
When Should You Skip the Cash-Out?
Sometimes the honest answer is no. If your first mortgage has terms you cannot match today, refinancing it just to extract cash can cost you. A cash-out replaces the whole balance. It also resets your loan term, which can extend your payoff time.
Run a break-even check: how long will your monthly savings take to cover the closing costs? If you will sell or refinance again before then, the math fails. In that case, a standalone second lien may serve you better, leaving the first untouched.
One more thing. Mortgage insurance applies above 80% LTV, so a high-leverage lane may add that cost. It cancels on request at 80% of original value and ends automatically at 78%, under the Homeowners Protection Act, with conditions including no subordinate liens for the cancellation request. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Pre-Application Checklist
- Current payoff statements for both loans
- The HELOC credit limit, not just the balance
- Settlement statement or title policy if the second was purchase-money
- Two years of income documents and recent pay records
- A list of debts you plan to pay off with the proceeds
- A clear goal: cash amount, lower payment, or one simple loan
Frequently Asked Questions
Can I do a cash-out refinance if I have a HELOC?
Yes, in most cases. You either pay off the HELOC inside the new loan or keep it and ask the HELOC lender to resubordinate. Combined leverage must still fit the program ceiling, and approval is subject to lender guidelines.
Does an unused HELOC still count against me?
Often, yes. Some lenders count the full credit limit toward combined leverage, drawn or not. An open line can also need a subordination agreement or closure. Ask for the lender’s treatment before you apply.
Will paying off my second mortgage reduce the cash I get?
Yes. The payoff comes out of the new loan first, so your net cash is what remains after both payoffs and closing costs. The gross loan amount is not your check.
Can I use an FHA Streamline or VA IRRRL to pull cash out?
No. The FHA Streamline limits cash back to $500, and the VA IRRRL replaces only the existing VA loan.
What if my second mortgage is recent?
Seasoning on the first mortgage being paid off is 12 months, but that rule does not apply to second liens being paid off. A recent second still gets reviewed for how its funds were used.
