The Quick Read: A conventional refinance finances the payoff of your current first mortgage, plus closing costs and prepaid items if you choose to roll them in. It does not finance much cash to you. On a one-unit primary residence, a rate-and-term refinance reaches 95% loan-to-value, and 97% in a narrow case. A cash-out refinance stops at 80%. Every figure is subject to lender guidelines and full file review, and none of it is a commitment to lend.
What Does “How Much It Finances” Actually Mean?
The new loan amount is the old payoff plus whatever you choose to add, up to a leverage cap. That is the whole idea. Everything else is detail about what may be added and where the cap sits.
Refinance savings and break-even estimate
The starting figures are an example value with a balance in proportion and a placeholder for costs. Replace them with yours, and enter the current rate from your statement.
Editable benchmark: 7.32% as of October 22, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a refinance quote.
Illustrative starting assumptions: a $350,000 home value, a $245,000 current balance, a current rate you enter and a remaining term seeded at twenty-five years, closing costs seeded at $5,000 as an editable placeholder (not a fee quote) and rolled into the new loan, 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 new rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a refinance quote; a refinance is priced by the lender at lock, and the current rate, the remaining term and the closing costs are figures you enter. The current payment is estimated from the balance, the current rate and the remaining term; the break-even divides the closing costs by the monthly saving and ignores the interest effect of a longer term. On the VA IRRRL the funding fee is added to the loan unless the veteran is exempt. Taxes and insurance are editable estimates. Licensed in sixteen states for consumer mortgages; Lendmire is a broker, never the lender.
Three pieces make up the number:
- The payoff. The balance on your current first mortgage, plus interest owed to the day it is paid off.
- Rolled-in costs. Closing costs, points and prepaid items can go into the new balance instead of coming out of your pocket. Freddie Mac's no cash-out refinance page says closing costs, financing costs and prepaids/escrows can be rolled into the new loan amount.
- A purchase-money second. If you took a second lien at the time you bought the home, it can be paid off in the same transaction.
Then the cap applies. Your appraised value times the program's maximum loan-to-value is the ceiling. The new loan can land anywhere under it, and for a payment problem you will usually want it well under.
How Is the New Loan Amount Built, Step by Step?
Start with the payoff, add what you choose to finance, and test the total against value. Then test the new payment against your income. That order matches how a file is worked.
1. Classify the purpose. The wholesale programs Lendmire places files with split refinances into two types. Rate-and-term (agencies call it limited cash-out or "no cash-out") pays off the first mortgage and costs. Cash-out gives you meaningful proceeds. Which bucket you land in sets your leverage cap.
2. Set the value. An appraisal is the default. In some cases the automated system can accept a prior appraisal on file and waive a new one. Per Fannie Mae's value acceptance page, that option has its own leverage ceilings for refinances, and it is decided by the system, not requested by the borrower.
3. Add up the loan. Payoff, plus costs and prepaids you want financed, plus any eligible purchase-money second.
4. Test leverage. Divide the new loan by the value. If it is over the cap for the loan type, the amount has to come down or the borrower brings cash.
5. Test the payment against income. The new principal-and-interest, taxes, insurance, mortgage insurance if any, and HOA dues are added to your other monthly debts. That total divided by gross monthly income is your debt-to-income ratio. The automated finding governs most files, with a ratio ceiling of 50%.
6. Review credit and reserves. The wholesale conventional programs start at a 620 decision score. Higher leverage, higher ratios and cash-out each ask more of the file.
7. Review the disclosures. Your Loan Estimate shows the loan amount and cash to close. Check it against the Closing Disclosure before signing.
Rate-and-Term or Cash-Out: Which Fits a Payment Problem?
Rate-and-term fits almost every payment problem. It allows far more leverage, so a borrower with thin equity has room. Cash-out is built for pulling equity, and it caps leverage lower.
| Factor | Rate-and-term (limited cash-out) | Cash-out |
|---|---|---|
| One-unit primary residence | Up to 95% LTV | Up to 80% LTV |
| Special case | 97% if existing loan is agency-owned | Wholesale lane to 89.99% |
| Two- to four-unit primary | Lower than one-unit | 75% LTV |
| Cash to you | Incidental only | Allowed |
| Seasoning | None on the loan itself | 12 months on the old mortgage, 6 on title |
| Mortgage insurance | Required above 80% | Required above 80% |
The 97% case needs more than equity. Per Fannie Mae's guide on limited cash-out refinances, that band applies where Fannie Mae owns or securitizes the existing loan, the lender flags it, and the file goes through the automated system. The first-time-buyer program also has to allow it. Ask your loan officer to check whether your existing loan is eligible. Don't assume.
A second note on the table. Pricing differs between the two types. Cash-out generally carries added pricing adjustments. That is another reason a payment-driven borrower is usually better off staying in rate-and-term.
What Caps the Amount?
Leverage, property type, occupancy, and the ratio test cap the amount. Equity is the first gate, and income is the second. Either one can stop a loan the other would allow.
- Equity. Value times the cap. A home worth less than expected at appraisal shrinks the ceiling directly.
- Units and occupancy. A one-unit primary residence gets the most room. Two- to four-unit primaries, second homes and rentals are held to lower caps on the cash-out side. If the home you are refinancing is a second home, occupancy decides the leverage, and the answer is lower than for a primary.
- Ratios. The 50% ceiling is a ceiling, not an entitlement. Fannie Mae's debt-to-income guidance sets 50% for automated underwriting and lower figures for manual files. The system weighs credit, reserves and leverage together. A file can be declined below the ceiling.
- Manual underwriting. Manually underwritten loans run 36%, extendable to 45% when the Eligibility Matrix score and reserve factors are met.
- Property type. Manufactured homes are limited in what they can refinance, and cash-out leverage on them is much lower. Condos and 2–4 unit properties are generally excluded from appraisal waivers.
Can Closing Costs Be Financed, and What Does That Do to the Payment?
Yes, on a rate-and-term refinance closing costs can often be rolled into the balance, subject to lender guidelines. The catch is that a bigger balance raises the payment a little. Rolling costs in trades cash today for a larger loan for the life of it.
Run it as a trade. Pay the costs at the table and the new balance equals the old payoff. Roll them in and the balance is higher by that amount, which lifts the payment a little and adds interest over time. Neither choice is wrong. The right one depends on how much cash you have and how long you plan to stay.
Some marketing talks about a "no-closing-cost" refinance. That term is in quotation marks for a reason. The costs don't vanish. They are built into the rate or into the balance.
Break-even is the test. Divide the costs you financed or paid by the monthly savings, and you get the number of months before the refinance pays for itself. If you sell or refinance again before that point, you lost money. A short expected stay in the home is a common reason a refinance fails this test.
Mortgage Insurance: The Equity Line That Moves Your Payment
Above 80% loan-to-value, conventional loans carry mortgage insurance. At or below it, they don't. That single line can move a payment more than a change in term.
Published typical annual premiums run from 0.58% to 1.86% of the balance. That is a range, not a quote. Your actual figure depends on score, leverage and the loan.
Two cancellation rules matter on a conventional loan:
- You can request cancellation at 80% of the original value, with a good payment history, no subordinate liens and no decline in value.
- The servicer must end it automatically at 78%.
Here is where a refinance can help. If your home has appreciated, a new appraisal may put the new loan at or under 80%, and at that level mortgage insurance is no longer required. If you finance heavily to the 95% cap, you add insurance back. That trade deserves a real look before choosing the maximum.
A wholesale lane also reaches 89.99% loan-to-value on a cash-out with no mortgage insurance. It needs a 680 score, a 50% ratio ceiling, a thirty-year fixed rate, a primary residence, a conforming balance, and its own six months of seasoning. Texas homestead cash-outs are held to the state constitution's cap, and that lane is not written there.
Edge Cases Where the General Rule Breaks
The rules above bend in a few named situations. Know them before you assume your file is standard.
Cash-out creep. Limited cash-out allows only a small, capped amount of cash back. Fannie Mae's guide also says only subordinate liens used to buy the property may be paid off in this type. Pay off a HELOC or a second you used for a kitchen, and the loan becomes cash-out. The cap drops to 80% and the pricing adjusts. Borrowers get caught here more than anywhere. Decide before application whether a second lien is coming off.
Recent title or a young loan. Cash-out requires the first mortgage to be at least 12 months old, note date to note date, and a borrower on title for six months. Delayed financing for cash buyers, inheritance and legal awards such as divorce settlements have exceptions. A co-owner buyout is also treated differently on the 12-month rule.
Little equity. When your leverage is above the standard limits, a high-LTV refinance option exists for qualifying Fannie Mae loans. Per Fannie Mae's high-LTV refinance rules, the existing loan must be a first-lien conventional loan Fannie Mae owns or securitizes, with a note date on or after October 1, 2017, and at least 15 months of seasoning. It also has to give a benefit, such as a lower principal-and-interest payment, a lower rate, a shorter term, or a move to a more stable product. Ask your loan officer whether it is currently available. Availability can change.
Credit events. The agencies set waiting periods after a bankruptcy, foreclosure or short sale: four years from a chapter 7 discharge, seven from a foreclosure, four from a short sale or deed-in-lieu. Shorter periods may apply with documented extenuating circumstances.
Fannie Mae versus Freddie Mac. Terms and details differ. Freddie Mac calls the rate-and-term product "no cash-out." The lender chooses which agency buys the loan, so a file that stalls on one set of rules is sometimes reviewed under the other.
Government streamlines. If your current loan is FHA or VA, a streamline may beat a conventional refinance. FHA Streamline needs no appraisal and limited credit review, with a net tangible benefit. VA IRRRL carries a 0.5% funding fee unless exempt, no VA appraisal and a net tangible benefit. Above the conforming limit, jumbo lanes take over, with a 660 decision score and leverage to 90%.
The Four Levers That Lower a Payment
A refinance lowers a payment through four levers. Rate and term get the attention. Mortgage insurance and debt consolidation often do more.
| Lever | Best for | Watch out for |
|---|---|---|
| Lower interest rate | Borrowers whose current loan is well above market | Closing costs and break-even |
| Longer term | Borrowers who need immediate relief | More total interest over time |
| Dropping mortgage insurance | Borrowers with grown equity | New appraisal must support 80% |
| Consolidating other debt | Borrowers with high-balance cards or loans | Moves unsecured debt onto the house |
A longer term lowers the payment because it spreads the balance over more months. It also generally means more total interest. Pay back the new loan on the old schedule and you keep most of the benefit. Reset to a full thirty years and you pay for it later.
Consolidating debt through cash-out can lower your total monthly obligations, and your DTI with it. It also puts that debt behind a loan with lower leverage limits and a lien on your home. Think hard before converting unsecured balances to secured ones.
Will You Qualify on the New Payment?
You qualify on the new payment, not the old one. Credit, DTI, reserves and leverage are weighed together, and the new payment is the number the ratio is built from.
The wholesale programs start at a 620 decision score. An adjustable rate under manual underwriting starts at 640. A higher score helps with leverage and mortgage insurance. A ratio near 50% is where files need strength elsewhere, such as reserves, credit and lower leverage.
Cash-out has an added check. For automated files with a ratio above 45%, Fannie Mae's cash-out guidance calls for six months of reserves.
Lenders must also make a good-faith determination that you can repay. That check looks at whether you can afford the loan, not whether you will feel comfortable with it. The CFPB's home loan toolkit makes that distinction. The comfort question is yours to answer.
If a ratio blocks you today, the usual fix is on the debt side. Pay down a card or an installment loan, then rework the numbers. Raising score or documented income helps too. Reapply when the file changes, not before.
When a Refinance Is the Wrong Tool
A refinance is the wrong tool when you will move soon, when the savings are small, or when a longer term costs more than it saves. Break-even is the test, and some files fail it.
- Short expected stay. If you will sell before break-even, the costs never come back.
- Tiny improvement. A small monthly drop against full closing costs may not be worth a new loan.
- Stretching a nearly paid-off loan. Resetting a short remaining term to thirty years can lower the payment and raise total cost a lot.
- Hardship, not rate. If you cannot keep up and cannot qualify, a refinance may not be available. Talk to your servicer about modification or other hardship routes, and consider a loan recast if you can make a lump-sum payment.
What the Decision Looks Like in Practice
Picture a homeowner with a primary residence, a first mortgage and no second lien, who wants a lower payment. Appraisal supports value well above the payoff. The borrower expects to stay for years.
The path: stay in rate-and-term. Check whether the new loan lands at or under 80% to drop mortgage insurance. Decide whether to pay closing costs or roll them in, and run break-even on that choice. Confirm the new payment keeps the ratio comfortably under the ceiling.
Now change one fact. The same homeowner has a HELOC to pay off. The loan becomes cash-out, leverage caps at 80%, and the file needs seasoning checks. If equity is thin, that cap may block the whole plan. That is the point of classifying the loan first.
Bring these to your loan officer: your current payoff, your current payment, any second liens, your estimated value, and your goal. With those, the loan shape is usually clear.

Frequently Asked Questions
Can I roll closing costs into a conventional refinance?
Yes, on a rate-and-term refinance. Closing costs, points and prepaid items can be added to the new balance, as long as the total stays within the leverage cap. The tradeoff is a larger balance and more interest over time, so run break-even before choosing.
Does paying off my HELOC change the loan type?
Usually, yes. Only subordinate liens used to buy the property may be paid off in a rate-and-term refinance. A HELOC used for improvements or other spending makes the loan cash-out. That lowers the cap to 80% on a one-unit primary residence.
How much equity do I need?
On a one-unit primary residence, rate-and-term reaches 95% loan-to-value, so roughly 5% equity is the starting point. Cash-out stops at 80%, which means 20% equity. Mortgage insurance applies above 80%. All figures are subject to lender guidelines and full file review.
Is a 50% debt-to-income ratio an approval?
No. It is the ceiling for automated underwriting, not a guarantee. The system weighs credit, reserves and leverage together, and a file can be declined at a lower ratio. Manual underwriting runs lower, at 36% or 45% with added score and reserve requirements.
Can I skip the appraisal?
Sometimes. The automated system may offer value acceptance when it finds a usable prior appraisal on the property. You cannot request it, and it is not offered on every property type, such as 2–4 unit homes. Otherwise, expect an appraisal.
