The Quick Read: A conventional refinance replaces your current mortgage with a new loan that follows Fannie Mae or Freddie Mac rules. On a home you live in, it can lower your monthly cost, change your term, drop mortgage insurance, or pull out some equity. Each benefit has a catch, and whether it pays off depends mostly on how long you keep the home.
The Short List
- A refinance is a brand-new loan. It pays off the old one, so the old loan’s terms stop mattering.
- Your current loan does not have to be conventional. FHA and VA borrowers refinance into conventional loans too.
- Primary-home leverage runs higher than any other occupancy. A no-cash-out or limited cash-out refinance can reach 95% LTV, and 97% in one narrow case.
- Mortgage insurance can end if your new balance lands at or below 80% of the home’s value.
- Cash-out is capped at 80% LTV on a one-unit home you live in, with waiting periods.
- Closing costs are real. A refinance only wins if you stay long enough to earn them back. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
What a Conventional Refinance Does for a Home You Live In
A conventional refinance trades your existing mortgage for a new one that Fannie Mae or Freddie Mac can buy from the lender. Those two companies write the rulebook. That is why the loan is called conventional: no government agency like FHA or VA insures it.
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.

Occupancy matters more than most people expect. You live in the home, so you get the highest leverage the agencies allow, the lowest credit hurdles, and the most flexible mortgage insurance rules. The same refinance on a second home or a rental carries tighter caps. Rental properties are a different loan lane and not covered here.
Lendmire is a mortgage broker. It arranges conventional loan programs through wholesale lenders. Across those programs, wholesale lenders generally start at a 620 decision score, and the automated underwriting finding governs most files, with a total debt ratio ceiling of 50%. Exact terms vary by lender, subject to lender guidelines and full file review.
Refinances come in two main flavors:
- Rate-and-term (limited cash-out). The new loan pays off your first mortgage, your closing costs, and any second lien used to buy the home. You get only incidental cash back.
- Cash-out. The new loan is bigger than what you owe, and you take the difference. It carries a lower LTV cap and waiting periods.
How the Loan Is Underwritten, Step by Step
Underwriting a refinance follows the same logic as a purchase, with extra paperwork to verify what is being paid off. Here is the path.
1. You apply and the lender classifies the loan. This is the fork in the road. Limited cash-out or cash-out? That one label sets your LTV cap, your pricing tier, and your waiting periods.
2. The lender pulls credit and checks your payoff items. If you paid off any second lien, the lender wants proof it was used entirely to buy the home.
3. Automated underwriting reviews the file. Fannie Mae and Freddie Mac each run a system that weighs income, assets, credit, and payment history. When the automated system approves, the deal works forward. When it does not, an underwriter may review it by hand under stricter ratio limits, 36% or 45% depending on the reserve and score factors.
4. The home gets valued. Sometimes that means a full appraisal. On some loans Fannie Mae offers "value acceptance," which skips the appraisal when its system trusts the data. If the offer is not made or is lost, an appraisal is required.
5. You get your disclosures and sign. You compare the final numbers against your original estimate, line by line.
6. You get a short right to cancel. On a refinance of your primary home, the Consumer Financial Protection Bureau says you have three business days to change your mind. It must be in writing. A phone call does not count. Cancelling does not erase your duty to keep paying the old loan.
What decides the outcome? Five things: the loan purpose, the LTV against the cap, your credit and debt ratio, how long you have held the home and loan, and the value.
The Benefits, With the Catch Attached
Every benefit below pairs with its trade-off. Skim for yours.
Lower payment, or a different one
A refinance can lower your monthly cost, usually because the new loan's pricing is better than your old loan's. That can happen when your credit score has improved, when your equity has grown, or when market pricing has moved. The agencies also list consolidating a higher-cost second lien into one loan as a standard use.
The catch: stretching the term back out to thirty years can lower the payment while raising total interest paid over the life of the loan. You can win monthly and lose overall.
Less interest, or a faster payoff
Moving to a shorter term builds equity faster. A fifteen-year loan generally costs far less interest over time. The catch is the payment. It can rise, and a tighter budget is a real cost. A debt ratio near the program ceiling leaves little room for a surprise.
Dropping mortgage insurance
This is the benefit people ask about most. Mortgage insurance is required on conventional loans above 80% LTV. The Consumer Financial Protection Bureau explains that you can request cancellation at 80% of the original value, and the servicer must end it automatically at 78%, if you are current on payments. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
A refinance changes the math in two ways. First, if the new loan is at or under 80% of the home's value, the new loan carries no mortgage insurance at all. Second, "original value" resets to the appraised value at the time of the refinance. That can help if the home has gained value, since you start closer to the 80% line. It can also hurt if you were close to cancelling anyway.
Two other routes exist: request cancellation when your balance hits 80%, or wait for automatic termination at 78%. Requesting needs good payment history and no second liens. A refinance is worth running when the home has appreciated or you are about to pay down a lump sum.
The catch: refinancing does not remove mortgage insurance on its own. If your new LTV stays above 80%, you still pay it.
Switching an adjustable rate to a fixed one
If your current loan adjusts, a refinance can lock in a fixed payment. You trade the chance of a lower adjustment for certainty. Many homeowners value that. Note that manually underwritten adjustable-rate loans often face a higher score floor, 640 in the wholesale programs Lendmire places.
Pulling out equity
A cash-out refinance lets you borrow against what you have built. On a one-unit home you live in, the conventional cap is 80% LTV. For two- to four-unit primary residences it drops to 75%. One wholesale lane reaches 89.99% LTV with no mortgage insurance, at a 680 score and a 50% debt ratio on a thirty-year fixed, for a primary residence with a conforming balance. It has its own six months of seasoning, and it is not written in Texas. Final terms depend on lender guidelines, property type, leverage, and the borrower's complete credit picture.
The catch: you are swapping equity for debt, and the whole loan resets.
Better pricing from stronger credit
If your score and debt ratio have improved since you bought, a refinance is how the improvement shows up in your pricing. The catch: a hard inquiry and a brand-new account can nudge your score down briefly, and your loan age resets. Both usually fade.
Match Your Goal to the Refinance Type
| Your goal | Best-fit type | Main trade-off |
|---|---|---|
| Lower monthly cost | Rate-and-term | Longer term can raise total interest |
| Pay off sooner | Rate-and-term, shorter term | Higher monthly payment |
| Drop mortgage insurance | Rate-and-term at 80% LTV or less | Needs enough equity |
| Fix an adjustable rate | Rate-and-term | Give up possible downward adjustments |
| Fund a project or debt payoff | Cash-out | More debt, lower LTV cap |
| Reach 80% LTV | Cash-in (pay down at closing) | Uses savings up front |
A cash-in refinance is just a rate-and-term loan where you bring money to closing. It is the quiet strategy here. If you are a few points short of 80% LTV, a lump-sum paydown can eliminate mortgage insurance for the life of the new loan. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
The Break-Even Test
Here is the plain version. Take your total closing costs. Divide by your monthly savings. The answer is how many months you need to stay to come out even.
Run a hypothetical. Say the costs equal thirty months of savings. If you expect to sell in two years, you lose. If you plan to stay ten, you win comfortably.
Closing costs show up on your Loan Estimate, so ask for one early and compare. You can pay costs up front or roll them into the loan. Rolling them in keeps cash in your pocket. It also raises your balance, and you pay interest on it. Treat a "no-cost" refinance with suspicion: the costs are built into the rate or the balance. They did not vanish.
Two adjustments to the simple test:
- A term reset. If you refinance a loan that has run five years into a fresh thirty, you lengthen your payoff. Compare total interest, not just the monthly figure.
- Mortgage insurance. If the refinance drops it, count that monthly savings too. That can shorten break-even a lot.
Structures and Variations
Limited cash-out basics. For a principal residence, the Fannie Mae Eligibility Matrix sets the ceiling at 97% for a fixed-rate one-unit loan and 95% for an adjustable. In practice, 95% is the standard figure on a one-unit home. The 97% tier applies where the existing loan is agency-owned and the first-time-buyer program allows it. Fannie Mae's Selling Guide spells out the conditions for limited cash-out: at least one borrower on title at application, only purchase-money second liens rolled in, and any sale listing withdrawn before the new loan funds.
Cash back on a rate-and-term loan. It is not zero. Fannie Mae's SEL-2025-08 announcement caps incidental cash back at a small figure tied to the loan balance. Freddie Mac requires excess proceeds to be applied to principal. Either way, it is not a way to take equity out.
Cash-out seasoning. Two clocks run. The first mortgage you are paying off must be at least 12 months old, counted note date to note date. And you must have been on title for 6 months. Exceptions exist for inheritance, property awarded in a divorce or separation, and delayed financing after a cash purchase. These clocks do not apply to limited cash-out.
The cap that sets how much you can take. Lendmire's piece Conventional Cash-Out Refinance LTV Limits for a Primary Home walks through the 80% and 75% limits in detail. If your home has two to four units and you live in one of them, Lendmire also covers cash-out requirements on a 2-4 unit primary home.
Jumbo. If your balance exceeds the county conforming limit, a jumbo loan takes over. Wholesale jumbo lanes generally start at a 660 decision score and run leverage up to 90%, with a 50% debt ratio ceiling on the fixed lanes. County limits change, so check yours.
Conventional vs. Government Streamlines
If your current loan is FHA or VA, a streamline may beat a conventional refinance. Streamlines trade paperwork for a requirement that you show a benefit.
| Factor | Conventional rate-and-term | FHA Streamline | VA IRRRL |
|---|---|---|---|
| Existing loan | Any type | Must be FHA | Must be VA |
| Appraisal | Often, or value acceptance | None | No VA appraisal |
| Credit review | Full | Limited | Limited |
| Upfront fee | None of the kind | FHA premiums apply | 0.5% funding fee unless exempt |
| Mortgage insurance | Ends at 80% LTV | Stays for FHA | Not applicable |
The honest read: a streamline wins when you want simplicity and are happy to stay in the same program. A conventional refinance wins when you want mortgage insurance gone or want to move out of FHA's longer premium schedule.
Where the Rules Bend or Break
- Second liens. A purchase-money second can be rolled in. Any other second makes the loan cash-out. People miss this constantly, and it changes the LTV cap from 95% to 80%.
- Occupancy. The right to cancel covers your principal dwelling only. Second homes and rentals do not get it. Also, Freddie Mac requires that all borrowers occupy the home on a primary-residence cash-out. A co-borrower who lives elsewhere can complicate that.
- Texas. A cash-out on a Texas homestead is capped by the state constitution at the agency figure, and the wholesale 89.99% lane is not written there.
- Property type. Manufactured housing has its own matrix, and some condo and co-op units face limits. Check the product before assuming eligibility.
- Accessory units. Rent from one accessory dwelling unit on a one-unit primary home may count toward qualifying on purchases and limited cash-out refinances.
- 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. Documented extenuating circumstances can shorten them.
- Loan size. Your balance has to fit under your county's conforming limit, or you are in jumbo territory.
When to Refinance, and When to Wait
You are likely a good candidate if:
- Your credit or debt ratio has improved a lot since you got the loan.
- Your home has gained value and you may be near 80% LTV.
- You plan to stay well past your break-even point.
- You hold an adjustable loan and want certainty.
- You have a second lien you want folded into one loan.
Hold off if:
- You expect to sell or move soon.
- The refinance would restart a thirty-year clock on a loan you have nearly paid down.
- Your equity is thin and the new loan stays above 80% LTV with mortgage insurance.
- Your debt ratio is already close to the ceiling.
- The cash you would take out covers spending that will not outlast the debt. Terms depend on the lender's guidelines, the property type, the leverage, and a full review of the credit profile.
Key Terms Defined
LTV (loan-to-value). Your loan balance divided by the home's value. A lower LTV means more equity and fewer restrictions.
Rate-and-term refinance. A refinance that replaces your loan without taking meaningful cash out. Agencies call it "limited cash-out."
Cash-out refinance. A refinance where the new loan is larger than the old one, and you receive the difference.
Seasoning. The waiting period the agencies require before a loan or ownership counts for a certain refinance type.
Mortgage insurance. Coverage that protects the lender when your down payment or equity is under 20%. It is removable on conventional loans.
Note date. The date you sign your promissory note. It starts the clock on how old a loan is.
Value acceptance. Fannie Mae's offer to accept a home's value without a new appraisal, based on its own data.
Frequently Asked Questions
Can I refinance an FHA or VA loan into a conventional loan?
Yes, and it is a common move. Your existing loan can be any type. The question is whether you meet conventional credit, debt ratio, and equity rules. Refinancing out of FHA is often how borrowers shed FHA mortgage insurance, provided the new loan lands near or under 80% LTV.
Will refinancing remove my mortgage insurance?
Only if your new LTV is at or under 80%. The new loan is measured against the home's current appraised value, so growth in value helps. If you stay above 80%, you carry mortgage insurance again. A cash-in refinance can bridge a small gap.
Does refinancing hurt my credit?
Slightly and usually briefly. The lender's credit pull shows as an inquiry, and the new account lowers your average account age. Both effects tend to fade as you make payments. Shop within a short window so the inquiries are treated as a single search.
How long do I have to wait to refinance?
It depends on the type. Limited cash-out has no seasoning clock on the property, though a prior refinance may need to be a minimum age. Cash-out needs 12 months on the loan being paid off and 6 months on title, with exceptions for inheritance, divorce awards, and delayed financing.
Can I take cash out on a rate-and-term refinance?
Only a small, capped amount. Fannie Mae allows incidental cash back, and Freddie Mac requires extra proceeds to go toward principal. Anything meaningful makes the loan cash-out, with its 80% LTV cap on a one-unit home you live in. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
What to Do Next
Start with a Loan Estimate and run the break-even against your own timeline. Then check your equity against the 80% line, because that single number often decides whether mortgage insurance goes away.
If you are weighing a refinance and want the break-even run on your own numbers, Lendmire can help you compare the programs on the same home. Eligibility is subject to lender guidelines and full file review, and nothing here is a commitment to lend.
