The Quick Read: A conventional cash-out refinance replaces your whole first mortgage with a new, larger one, so the new loan’s terms apply to every dollar you owe, not just the cash you take. That is the cost to weigh when your current mortgage is a good one. The offer only wins if the cost of the extra cash, measured across the full balance and the time you will hold the loan, beats keeping the first mortgage and borrowing another way.
What a Cash-Out Offer Does to Your Existing Loan
A cash-out refinance pays off your current first mortgage with a new first mortgage. The difference, after costs, comes to you as cash. The CFPB’s research staff describe a cash-out refinance as taking the place of the original mortgage, while home equity loans and HELOCs leave the original first mortgage in place.
That one difference drives the whole comparison. If your current loan has terms you like, a cash-out gives them up on the entire balance. A second lien (a home equity loan or HELOC) prices only the new money, but it adds a second payment behind your first loan.
This is the point where files stall. A borrower sees the cash amount and the offer, and never prices what happens to the balance they already owe.
Lendmire’s cash-out refinance programs are built for the borrower who has decided a full replacement makes sense. The rest of this piece is how to decide that.
The Three Paths Side by Side
Most homeowners with a low first mortgage have three realistic choices, plus doing nothing. The table lays out what each does.
| Factor | Cash-out refinance | Home equity loan | HELOC |
|---|---|---|---|
| Your low first mortgage | Paid off and replaced | Stays in place | Stays in place |
| New terms apply to | The whole new balance | Only the new money | Only what you draw |
| Payments | One | Two | Two |
| Closing costs | Apply to the larger balance | Usually lower | Usually lower |
| Term effect | May reset the schedule | Separate schedule | Draw period, then repayment |
| Best fit | Large need, or old loan is not low | Fixed amount, one use | Staged or uncertain needs |
The CFPB notes that second mortgages often carry higher interest than first mortgages, because the second lender is paid second if the home is sold to cover debts. It also says a second mortgage adds to your overall debt burden. So the second-lien path is not automatically the safe one. It protects the first loan and adds a layer of risk on top.
“Do nothing” belongs in the comparison too. If the cash is for something that can wait, or can be funded from savings, a more affordable offer may be no offer.
How Do You Test the Blended Cost?
The simplest test is a blended-cost comparison. Think of it as a weighted average of what you would pay under each path.
1. Take your current first mortgage balance. Note its terms, which are the good ones you would be giving up.
2. Take the cash you actually need. Add the closing costs you would finance, since they come out of your net cash.
3. For the second-lien path, weight your existing loan’s terms by the large balance and the new loan’s terms by the small amount of new money.
4. For the cash-out path, apply the new loan’s terms to the full new balance.
5. Compare the two weighted results.
Here is an illustration. Say your balance is large and the cash you need is small, perhaps 10% of the home’s value. Under a second lien, most of your debt stays on the low terms and only the small slice pays the higher second-lien price. Under a cash-out, 100% of the debt moves to the new terms. The smaller the cash need relative to the balance, the harder the cash-out is to justify.
Flip it. If the cash need is large compared with the balance, the weighting shifts. The new money is most of the debt, and a single new first mortgage can look better than a big second lien.
The blended test has limits. It ignores closing costs, term length and how the schedule amortizes. Treat it as a starting screen, not a verdict. The outcome depends on how the old loan’s terms compare with the new loan’s, weighted by balance and cash needed. No path wins every time.
Beyond the Blend: Break-Even and the Cost of the Cash
Once the blend points one way, test it over the time you expect to keep the loan.
Step one: price the cash. Work out the extra yearly cost of moving your old balance onto new terms. Add the yearly cost of the new money. Divide the total extra cost by the cash you receive. That is the effective yearly cost of the cash. If you are repricing a large low-cost balance to get a small amount of cash, this number can be uncomfortably high even when the new loan’s terms look fine on their own.
Step two: add the upfront costs. Refinance closing costs apply to the whole new balance. A second lien generally costs less to close. Neither is free, and the CFPB’s Loan Estimate explainer defines closing costs as the upfront charges to get the loan and transfer ownership.
Step three: choose your exit date. Estimate how long you will own the home or keep the loan. Compare total cost under both paths through that date. Upfront costs weigh heavily on a short hold. Higher ongoing cost on a repriced balance weighs heavily on a long one.
Step four: check the term. A new thirty-year loan restarts your amortization. You may build equity more slowly in the early years than you do now. If you can, ask for a term that matches what you have left. Then compare the schedules, not just the payments.
Run steps one through four for each offer you hold and each alternative. Then compare net cash, ongoing cost and total cost to your exit date, side by side.
How to Compare Several Cash-Out Offers
Every lender must give you a Loan Estimate, a standard form built so you can compare offers. The CFPB says it makes comparing offers from multiple lenders easier. A Loan Estimate is not an approval. It is a quote on a standard form.
When you hold two or three, line them up on the same points:
- Loan amount, and how much of it is financed closing costs.
- Origination charges, compared line by line.
- The services you cannot shop for, versus the ones you can. The CFPB points out you can shop for the services in Section C of page 2.
- Whether mortgage insurance applies and how it ends.
- The term, and whether it resets your schedule.
- The five-year cost summary, not only the headline interest figure.
The CFPB’s home loan toolkit advises getting at least three written offers and cautions that a low APR can still carry high upfront costs. The lowest advertised number is not automatically a more affordable loan. Two offers with different cost structures only compare fairly once both are run through your exit date.
(One habit that keeps this clean: request all offers on the same loan amount and the same term. Otherwise you are comparing different loans.)
Conventional Guardrails: What Limits the Cash
Before any offer can be priced, the loan has to be eligible. Across the wholesale conventional programs Lendmire works with, these are the main limits on a cash-out. Every figure is subject to lender guidelines and full file review, and nothing here is a commitment to lend.
| Item | Conventional cash-out |
|---|---|
| Max LTV, one-unit principal residence | 80% |
| Max LTV, 2-4 units, second home, investment property | 75% |
| Seasoning on the loan being paid off | At least 12 months, note date to note date |
| Time on title | Borrower on title for 6 months |
| Typical credit floor, wholesale conventional | 620 decision score |
| Total ratio ceiling | 50% on automated findings |
Conventional cash-out generally allows a lower maximum LTV than a purchase, which is why the cash you can reach is smaller than the leverage you could have used to buy. Fannie Mae’s Eligibility Matrix sets maximum leverage by occupancy and unit count, and its Selling Guide section on cash-out transactions requires at least one borrower on title for six months. The same guide says that on files run through Fannie Mae’s automated underwriting, a debt ratio above 45% triggers a six-month reserves requirement.
The 12-month rule on the existing mortgage comes from Fannie Mae’s cash-out eligibility update. If your current loan is newer than that, a cash-out refinance is off the table for now, whatever the offer says.
One more lane exists. A wholesale program reaches 89.99% LTV with no mortgage insurance at a 680 score and a 50% ratio on a thirty-year fixed. It applies to a primary residence with a conforming balance and carries its own six months of seasoning. In Texas, a cash-out on the homestead is capped by the state constitution, and that wholesale lane is not written there. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
A cash-out is also priced differently from a standard refinance. Fannie Mae applies a loan-level price adjustment to certain cash-out loans, based on LTV and credit score. In plain terms, pricing rises with higher LTV and lower credit score. That adjustment sits on top of other price adjustments, and it is one more reason a cash-out costs more than a refinance with no cash taken.
Where the General Rule Breaks
The standard advice is to keep a low mortgage and borrow elsewhere. These edge cases bend it.
Paying off a second lien. Many homeowners think paying off a HELOC in a refinance is not a cash-out. Under Fannie Mae’s rules, paying off a non-purchase-money second makes the loan a cash-out, even if no extra cash is taken. If you only want to consolidate, you still get cash-out limits and pricing.
Keeping the second lien in place. If your HELOC stays and you refinance only the first, the HELOC lender must agree to stay behind the new loan. Fannie Mae requires a recorded resubordination agreement unless state law keeps the junior lien junior automatically. Lenders also count every lien on the home when they set the combined leverage, so a second lien raises that figure.
The home you just bought. Delayed financing is an exception to the six-month wait, not an exemption from underwriting. The purchase must have been an arm’s-length transaction. The new loan cannot exceed your documented initial investment plus financed costs, and cash-out pricing still applies. Confirm the current wording in the Fannie Mae Selling Guide before you plan around it.
Co-owner buyouts. Freddie Mac’s Guide allows a special-purpose cash-out to buy out a co-owner’s equity. That is a purpose where the numbers often favor replacing the loan, since you need the money for a specific reason.
Manufactured housing. Single-width manufactured homes are not eligible for standard cash-out under Fannie Mae’s manufactured housing matrix.
Occupancy changes the leverage. Second homes and investment property carry the lower cash-out LTV shown in the table above. Beyond that, this piece stays on the home you live in.
Recent cash-out. A limited cash-out refinance is not allowed if you completed a cash-out on the same property with a note date 30 days or less before the new application, per Fannie Mae’s refinancing practices rule.
Some states have special home-equity rules, and government loans (FHA, VA, USDA) follow their own programs and are outside this comparison.
Key Terms Defined
Cash-out refinance: a new first mortgage that pays off your current one and gives you the difference as cash.
Second mortgage: a loan secured by your home that sits behind your first mortgage, such as a home equity loan or HELOC.
LTV (loan-to-value): your loan balance divided by your home’s appraised value.
CLTV (combined LTV): all loans secured by the home, added together, divided by the home’s value.
Seasoning: the minimum time a loan or ownership must be in place before a cash-out is allowed.
Loan Estimate: the standard form each lender gives you to compare offers. It is not an approval.
When a Cash-Out Still Wins
Keeping the low loan is the default, not a law. A cash-out can be the better path when:
- The cash need is large compared with your balance, so a single first mortgage beats a big second lien.
- You are paying off debt whose cost clearly exceeds the cost of the new mortgage money. The CFPB’s research says paying down other debt with home equity makes sense only if the cost of getting the cash is below the cost of the debt, and warns that turning unsecured debt into mortgage debt puts the home at risk.
- Your current mortgage is not actually low, so little is lost by replacing it.
- You need a fixed, single payment and want to avoid variable exposure.
- You are buying out a co-owner.
It tends to lose when you need a small amount, need it in stages, or plan to sell within a few years.
Decision Matrix by Need
| Your situation | Usually points toward |
|---|---|
| Small, one-time need | Home equity loan |
| Staged or uncertain need | HELOC |
| Large need, balance modest | Cash-out refinance |
| Short hold before selling | Keep the first loan |
| Existing loan is not low | Cash-out refinance |
| Paying off high-cost debt | Compare costs; cash-out can fit |
HELOCs carry one more wrinkle. The CFPB says that if you sell, you are generally required to repay the HELOC in full right away. Weigh that against your expected exit date.
Before You Sign
Refinances and home equity loans on your principal home are covered by a right of rescission. The CFPB says you generally have three business days to cancel, with Saturdays counting and Sundays and legal holidays not. A waiver is possible only for a genuine personal financial emergency.
Gather these before you talk to any lender:
1. Your current mortgage statement, with balance and note date.
2. Any HELOC or second lien statement.
3. The cash you need and what it is for.
4. Your expected exit date.
5. Two or three Loan Estimates on the same amount and term.
Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
Frequently Asked Questions
Does a cash-out refinance reprice my whole mortgage?
Yes. The new loan replaces the old one, so its terms apply to the full new balance. A second lien prices only the new money, which is why it often protects a low first mortgage better.
Is paying off my HELOC in a refinance really a cash-out?
Under Fannie Mae’s rules, yes. Paying off a non-purchase-money second lien makes the loan a cash-out refinance, whether or not you take extra cash. Expect the cash-out leverage limit and pricing to apply.
How soon after buying can I do a cash-out?
Conventional rules generally need a borrower on title for six months, and the mortgage being paid off must be at least 12 months old. Delayed financing is an exception for recent purchases, and it still involves an appraisal, underwriting and cash-out pricing.
Is the lowest quoted number always a more affordable offer?
No. A low headline figure can come with high upfront costs. Compare the Loan Estimates line by line, including the five-year cost summary, on the same loan amount and term.
How much cash can I get out?
It depends on your appraised value and the leverage cap. On a one-unit principal residence, conventional cash-out generally reaches 80% LTV, and lower on two- to four-unit homes. All figures are subject to lender guidelines and full file review, and none is a commitment to lend.
