The Quick Read: It depends on what kind of second mortgage you have and how much cash you want. If the second was used to buy the home and you take only small incidental cash, the refinance can run as a rate-and-term (limited cash-out) loan. If the second was borrowed for anything else, such as a HELOC used for repairs, the combined loan is generally treated as cash-out. Cash-out carries lower leverage limits, so the loan type, not a brand name, decides the best fit.
Key Takeaways
- The purpose of the second lien decides the loan type. Purchase-money seconds are treated differently from seconds used for other things.
- Conventional cash-out on a one-unit primary residence tops out at 80% LTV. A rate-and-term refinance can reach 95%.
- Government loans (FHA, VA) have streamline products, but those streamlines cannot pay off a second mortgage.
- You have three structures to choose from: combine both loans, refinance only the first, or replace only the second.
- Combining can cost you a low first-mortgage rate. That tradeoff deserves as much attention as the program. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
What “Combining” Actually Means
Combining a first and second mortgage means one new loan pays off both existing liens. You end up with one lender, one payment and one lien on the home.
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.
The catch is how the lender labels it. Fannie Mae’s Selling Guide, in its subordinate financing section, sorts these refinances by what happens to the second lien. Paying off a purchase-money second with no extra cash is limited cash-out. Paying off a second that was not used to buy the home is cash-out, even if you take no additional money at closing.
That one classification drives everything downstream: maximum leverage, seasoning rules, pricing adjustments and which loans are even on the table.
How Is the Loan Classified? A Step-by-Step Walk-Through
Across the wholesale programs Lendmire’s brokers place files with, the underwriting sequence is consistent. Here is how a file moves.
Step 1: Inventory every lien. The lender needs the first mortgage payoff and the balance of any second or HELOC. With a HELOC, the credit limit matters too, not just the current balance, because the lender must know what could still be drawn.
Step 2: Classify the second. Was it used to buy the home, or for something else? Freddie Mac’s no cash-out refinance rule says that when a junior lien is paid off in a no cash-out deal, the file must document that the full lien amount went toward buying the property. A HELOC that funded part of the purchase and part of a kitchen remodel generally pushes the file toward cash-out.
Step 3: Pick the structure. More on this below.
Step 4: Appraisal and leverage. The appraised value sets your loan-to-value ratio. A low appraisal shrinks the cash you can reach, and on a cash-out it can shrink the whole plan.
Step 5: Seasoning and ownership checks. For a conventional cash-out, the first mortgage being paid off must be at least 12 months old, measured from note date to note date, as Fannie Mae’s announcement SEL-2023-01 states. The borrower also generally needs six months on title, with exceptions for delayed financing, inheritance and legal awards.
Step 6: Resubordination, if a second stays. If you keep the second, its holder must agree to sit behind the new first mortgage. That is a separate approval you do not control.
Step 7: Credit, ratios and reserves. Wholesale conventional programs generally start at a 620 decision score, and the automated underwriting finding governs most files, with a total debt-to-income ceiling of 50%. Manually underwritten files use tighter ratios of 36% or 45%, depending on reserves and score factors. All of this is subject to lender guidelines and full file review.
Rate-and-Term vs. Cash-Out: What Changes
| Factor | Rate-and-term (limited cash-out) | Conventional cash-out |
|---|---|---|
| Max LTV, one-unit primary | 95% | 80% |
| Second mortgage | Purchase-money only | Any second can be paid off |
| Cash back to you | Only incidental | Allowed |
| Seasoning on existing first | Lighter | 12 months, note to note |
| Pricing | Lower adjustments | Added loan-level adjustments |
| Mortgage insurance | Required above 80% LTV | Not needed at or below 80% |
Two- to four-unit primary residences, second homes and investment properties cap at 75% on a conventional cash-out. Occupancy simply sets the leverage, and the 75% figure is the answer.
Cash-out pricing costs more than rate-and-term. Fannie Mae’s cash-out guidelines apply a loan-level price adjustment to many cash-out loans, driven by LTV and credit score. That is a mechanic of the loan, not a quote, and your Loan Estimate shows the real cost for your file.
The Three Structures
Most homeowners assume combining is the only path. It is one of three, and the best program for your situation often turns on which of these you choose.
1. Combine both into one new loan. One payment, one lender. Classified as limited cash-out or cash-out based on the second lien’s purpose. This is the cleanest outcome, and the usual choice when the second carries a meaningful balance.
2. Refinance only the first and keep the second. The second lender must agree to resubordinate. If they refuse, this option is dead. In that case you either combine, replace the second yourself, or leave things alone. Fannie Mae’s guidelines treat a retained second with limited cash taken as limited cash-out; take more cash and it becomes cash-out.
3. Replace only the second, leave the first untouched. If your first mortgage was locked in under favorable terms, this protects it. You pay a new second lien’s costs and keep the first as-is.
The decision comes down to arithmetic you can run on your own statements. If the new combined loan would be on worse terms than your current first mortgage, combining trades a known good loan for convenience. That is a genuine toss-up for many borrowers. Lendmire’s piece Cash-Out Refinance vs Second Mortgage When Your First Rate Is Low walks through that tradeoff in more depth.
Does a Government Program Work Here?
Short answer: not for combining. Government streamlines are built to refinance one loan, not to absorb a second.
- FHA Streamline. For an existing FHA loan: no appraisal, limited credit review and a net tangible benefit requirement. No cash can come out, and an existing second must be resubordinated rather than paid off. FHA does have a rate-and-term option at 97.75% LTV with an appraisal, which can consolidate liens when the second qualifies.
- VA IRRRL. The IRRRL refinances an existing VA loan, with a 0.5% funding fee unless exempt, no VA appraisal, a net tangible benefit requirement and seasoning of the later of 210 days and six payments. VA’s IRRRL page states that no loan other than the existing VA loan may be paid from the proceeds, and that a second mortgage holder must agree to subordinate. To pay off a second or take cash, a veteran needs a VA cash-out refinance, not an IRRRL.
- Jumbo. Above the conforming limit, jumbo lanes take over: 660 decision score, leverage to 90%, loans to $5,000,000 and a 50% ratio ceiling on the fixed lanes.
A common misconception is that a streamline can roll in a HELOC. It cannot.
Where the General Rule Breaks
The headline rule is simple: purchase-money second equals limited cash-out, anything else equals cash-out. Several situations bend it.
A HELOC drawn for mixed purposes. Part purchase, part something else. Underwriters generally view partial purchase-money status as pushing the file toward cash-out, because the documentation standard is “the full lien amount went to the purchase.”
A HELOC as your only lien. If you own the home with a HELOC and no first mortgage, paying it off is generally treated as cash-out. A home owned free and clear is also treated as cash-out when you borrow against it.
Recent first mortgage. If your first is under 12 months old, a conventional cash-out is off the table for now. A rate-and-term refinance can have lighter seasoning, though the loan being paid off still needs some age. Freddie Mac’s guide sets a 30-day minimum on the loan paid off in a no cash-out refinance.
Listed for sale. A home actively listed for sale at disbursement generally is not eligible for these conventional refinances.
PACE obligations. A PACE (energy retrofit) lien must be paid in full as part of the transaction, and it can make a refinance ineligible if sufficient equity exists to retire it and you don’t.
Co-borrower who doesn’t live there. On a cash-out of a primary residence, Freddie Mac’s cash-out rule requires all borrowers to occupy the home. Adding a non-occupant co-borrower to help income can break eligibility.
Student loan payoff. Some conventional programs waive the cash-out pricing adjustment when the proceeds pay student debt and requirements are met. Ask whether that feature fits your file.
Texas homesteads. A cash-out on a Texas homestead is capped by the state constitution at the agency figure, and the 89.99% wholesale lane is not written there.
The 89.99% Wholesale Lane (and Who It Fits)
Across the wholesale programs Lendmire places files with, one cash-out lane reaches 89.99% LTV with no mortgage insurance. It needs a 680 score and a 50% ratio on a thirty-year fixed, a primary residence, a conforming balance and its own six months of seasoning. It is not available everywhere and not on every file. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Does that make it the best cash-out program? Only for the borrower who needs more than 80% leverage, fits every box above and is not in Texas. For someone with a 700-score file and 60% equity, the standard 80% conventional cash-out reaches everything needed and nothing special is required. The best program for your situation is the narrowest one that does the job. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
What a Broker Does Differently
A mortgage broker does not lend. Lendmire’s cash-out refinance programs page covers the loan types, and the brokerage arranges them through a network of wholesale lenders. The practical value is matching: one lender may handle a purchase-money-plus-HELOC mix cleanly, another may be stricter on seasoning, a third may offer a different leverage ceiling. A broker shops those differences for your file instead of sending you to one set of guidelines.
Which lender fits depends on your situation: the property type, your credit profile, how much leverage you need and what documents you can produce. No ranking of lenders can answer that for you, and none should be trusted that claims to.
Which Structure Fits Which Borrower
| Your situation | Structure that often fits |
|---|---|
| Purchase-money second, small balance, want one payment | Combine; likely limited cash-out |
| HELOC used for renovations, need all of it paid off | Combine; treated as cash-out |
| Low-cost first mortgage, high-cost second | Replace only the second |
| Want to change the first but keep a small second | Refinance the first and resubordinate |
| Existing FHA or VA loan, no second to pay off | Streamline if you qualify |
| Thin equity, over 80% combined | Rate-and-term only if second is purchase-money |
What to Prepare
- Payoff statements for both loans, plus the HELOC credit limit.
- Proof of how the second was used. A closing disclosure from your purchase is the clearest document for a purchase-money second.
- Recent pay stubs, tax returns and bank statements, as the underwriter requires.
- A realistic picture of the value of your home. A low appraisal changes the options.
- A decision on what happens to the HELOC after payoff. Ask the HELOC lender how to close the line and whether early-closure terms apply.
Costs and Risks to Weigh
Combining replaces two payments with one, but the new loan is larger and may run longer. The CFPB’s guide to using home equity notes that a cash-out refinance can extend the time to pay off your mortgage and raise the monthly payment because a larger loan replaces the current one.
Other items to run through:
- Mortgage insurance. Required above 80% LTV. You may request cancellation at 80% of the original value with good payment history, no subordinate liens and no decline in value, and the servicer must end it automatically at 78%.
- Closing costs. They can be rolled into a conventional loan, but that means interest on them for the life of the loan. Terms like “no-cost” refinance just move the cost into the rate or the balance.
- Losing a favorable first mortgage. Mentioned above because it matters most.
- Behavior after closing. CFPB research found credit scores rose sharply after cash-out refinances, then gradually worsened, and card balances drifted back toward earlier levels. Combining liens frees up credit capacity; whether it helps depends on what you do next.
Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
If You Don’t Qualify Yet
A “no” today is often a “not yet.” Common fallback paths:
- Wait out the 12-month seasoning window on your first mortgage.
- Pay down the second to bring combined leverage under the cap.
- Refinance only the second, or only the first with resubordination.
- Ask a broker to rerun the file against a lender with different overlays.
Key Terms Defined
Purchase-money second: A second loan used at the time of purchase to help pay for the home.
Resubordination: A second lender’s agreement to stay behind a new first mortgage in lien priority.
LTV (loan-to-value): Your loan balance divided by the home’s appraised value.
CLTV: The same ratio, counting all liens on the home, not just the first.
Seasoning: The minimum time a loan or ownership must exist before it can be refinanced or cashed out.
Loan-level price adjustment: A pricing add-on that conventional programs apply based on factors like credit score and leverage.
Frequently Asked Questions
Can I combine my first and second mortgage into one loan?
Yes, in most cases. One new loan pays off both liens and leaves you with a single payment. Whether it runs as rate-and-term or cash-out depends on whether the second was a purchase-money loan and how much cash you take. Eligibility is subject to lender guidelines and full file review.
Is combining always treated as a cash-out refinance?
No. A purchase-money second paid off with only incidental cash back can be a limited cash-out (rate-and-term) refinance. A second used for anything else makes the combined loan a cash-out, even if no extra cash reaches you at closing.
Do I have to close my HELOC after it is paid off?
Generally yes. If a HELOC is paid off through the refinance, the lender requires the line to be closed so no new lien can attach. Check your HELOC agreement for any early-closure terms.
What if my second lender will not resubordinate?
Then keeping the second in place won’t work. Your options are to combine both loans, replace only the second yourself, or leave the loans as they are. A broker can compare structures once you know the second lender’s answer.
Does combining reset my loan term?
Yes, it can. A new loan starts a new term, so you may stretch the payoff date even if the payment falls. Compare the remaining years on your current loans with the new term before deciding.
