Suppose you owe $300,000 on a 30-year loan at 7.0%, with principal and interest of about $1,996 a month. You refinance to 6.0% and the payment drops to about $1,799, a saving of roughly $197 a month. Mortgage refinancing means replacing your existing home loan with a new one, ideally on terms that fit your finances better.
Those figures are illustrations based on standard amortization, not quotes, and your actual rate and costs depend on your credit, equity, property, and the day you lock. This guide from Duane Buziak, NMLS #1110647, covers the three main types of refinance, the process from pre-qualification to closing, what it costs, the break-even test, and how to tell whether it fits your situation.

How Refinancing Replaces Your Current Mortgage
A refinance is a brand-new loan. At closing, the new lender sends funds to your old lender, which pays the old balance in full. The old lien is released, a new lien is recorded against the property, and you start making payments under a new note with a new rate, term, and sometimes a different balance.
Homeowners refinance for a handful of reasons: to lower the rate, to shorten or lengthen the term, to pull out equity as cash, to drop private mortgage insurance (PMI), or to consolidate debt into the mortgage.
Two misconceptions come up constantly. Refinancing does not “adjust” your existing loan. It ends that loan and creates another, with fresh underwriting, an appraisal in most cases, and closing costs. It is also not a loan modification, which is a change your current servicer makes to your existing loan, usually because of hardship, without a new loan being originated.
Resetting the term matters more than most people expect. Suppose your $300,000, 7.0% loan is five years old and the balance is about $282,400. You have roughly $316,000 of interest left to pay over the remaining 25 years. Refinance that balance into a new 30-year loan at 6.0% and your payment falls to about $1,693, but total interest over the new life is roughly $327,000. The lower rate improved your monthly cash flow while the restarted clock added about $11,000 in lifetime interest. Neither result is wrong, but you should know which one you are buying. A shorter new term, such as 20 years, changes that outcome.
Rate-and-Term, Cash-Out, and Streamline: The Three Main Types
Rate-and-term changes the interest rate, the loan length, or both, without giving you meaningful cash. Cash-out replaces the loan with a larger one and pays you the difference. Streamline programs, the FHA Streamline and the VA Interest Rate Reduction Refinance Loan (IRRRL), cut paperwork for borrowers who already have an FHA or VA loan. Loan-to-value (LTV) is the new loan balance divided by the home’s appraised value, and it drives most of the limits below.
| Feature | Rate-and-Term | Cash-Out | Streamline (FHA Streamline, VA IRRRL) |
|---|---|---|---|
| Purpose | Lower the rate or change the term | Turn equity into cash | Lower the rate or payment on an existing FHA or VA loan with less documentation |
| Typical cash to borrower | None, apart from small escrow refunds | The difference between the new loan and the payoff, after costs | None in general |
| Key limits (as of 2026) | Needs enough equity and credit to qualify for the new rate | Conventional is capped at 90% LTV; VA allows up to 100% LTV | Requires an existing FHA or VA loan; must show a benefit such as a lower rate or payment |
| Best-fit situation | Rates or your credit have improved and you will stay past break-even | Home improvements, large expenses, or replacing higher-rate debt when the math works | FHA or VA borrowers who want a faster, lighter process |
Program rules and lender overlays change, so treat the table as a starting map. As of 2026, conventional cash-out is capped at 90% LTV, and specific programs and occupancy types may set lower ceilings. VA cash-out can reach 100% LTV for eligible veterans, though lenders may apply their own requirements.
Streamlines generally require that you already hold the FHA or VA loan, and documentation is often reduced, with an appraisal frequently not required. The VA explains IRRRL rules on its home loans pages, and HUD publishes FHA streamline guidance for FHA borrowers.
Two common goals are uses of these types, not separate products. Debt consolidation is usually done through a cash-out refinance, and PMI removal is often a byproduct of a rate-and-term refinance when your equity has grown past 20%.
The Refinance Process From Pre-Qualification to Closing
The sequence is fairly consistent across lenders:
- Set the goal. Decide whether you want a lower payment, a shorter term, cash, or PMI gone. The goal determines the loan type.
- Get a soft-pull pre-qualification. A soft inquiry does not affect your credit score. Duane Buziak offers soft-pull pre-qualification, so you can see realistic numbers first.
- Compare rates. Ask for written quotes on the same loan type, term, and lock period.
- Apply and submit documents. Expect pay stubs, tax returns or W-2s, bank statements, and your current mortgage statement.
- Appraisal. Most refinances need one, though some lenders and programs offer waivers when you are eligible.
- Underwriting. The lender verifies income, assets, credit, title, and the property, and may ask for more documents.
- Closing Disclosure and closing. You review final terms, sign, and the new loan pays off the old one.
Two federal forms make offers comparable. The Loan Estimate, delivered within three business days of application, shows the rate, payment, and estimated costs. The Closing Disclosure arrives at least three business days before closing and shows the final numbers. The Consumer Financial Protection Bureau walks through both forms line by line, and comparing the Loan Estimates side by side is the most reliable way to shop.
On a refinance of your primary residence, federal rules generally give you a three-business-day right of rescission after signing, during which you can cancel. Funds are typically not disbursed until it passes. If you refinance with your current lender, the right generally applies only to any new money above your existing balance. Check the CFPB’s current wording on this before you rely on it.
Where you shop matters too. A single-lender shop, such as Rocket or Movement, can offer you only its own rate sheet. A broker can compare hundreds of wholesale lenders and match your file to the one whose guidelines and pricing fit best.
What Refinancing Costs and How to Run the Break-Even Math
Closing costs fall into a few buckets:
- Lender and origination fees
- Appraisal
- Title and settlement services
- Government recording fees
- Prepaid interest and escrow deposits for taxes and insurance
Closing costs are often quoted as a percentage of the loan amount, but that percentage varies by state, lender, and loan, so rely on the fees itemized on your Loan Estimate instead of a rule of thumb.
The break-even formula is closing costs divided by monthly savings. Using the opening example with $6,000 in costs and $197 saved each month, $6,000 / $197 is about 30.5 months, so you break even near month 31. After five years, you have saved about $11,820 (60 months x $197). Subtract the $6,000 in costs and the net is roughly $5,820. If you sell or refinance again before month 31, you lose money on the deal.
Some borrowers choose no-out-of-pocket closing options, where the costs are covered through a lender credit in exchange for a slightly higher rate. That removes the upfront cash, but the higher rate shrinks your monthly savings and lengthens your break-even on what you would otherwise have paid. It works best when you have limited cash or expect to move or refinance again soon. It is a trade, not a free lunch.
A Virginia data point on loan size
Loan size determines which pricing tier you land in. For 2026, the Federal Housing Finance Agency (FHFA) set the baseline conforming loan limit at $832,750 for one-unit properties, with high-cost areas such as Fairfax County and other Northern Virginia counties allowed up to $1,249,125. Most Richmond-area counties use the baseline. Limits are set county by county, so confirm your county’s figure on the FHFA site before assuming a loan is conforming.
When Refinancing Makes Sense and When It Doesn’t
Refinancing tends to pay off when several of these are true:
- You will keep the home well past your break-even month.
- The rate drop is meaningful, not a rounding error.
- Your credit score or home value has improved since you bought, which can unlock better pricing.
- PMI could be removed, or an adjustable rate is about to reset upward.
It tends not to pay off when you plan to sell before break-even, or when you would restart a 30-year clock for only a small rate gain. Consolidating high-rate debt is the other trap. Rolling credit card balances into your mortgage lowers the payment, but it turns short-term debt into 30-year debt, and you may pay more interest overall unless you stop using the cards and pay the mortgage down faster.
PMI deserves its own check. Under the Homeowners Protection Act, PMI on many conventional loans terminates automatically when your balance is scheduled to reach 78% of the home’s original value, and you can request cancellation at 80%, provided you are current on payments and meet the servicer’s conditions. The CFPB explains PMI cancellation rules in its mortgage resources. If your loan does not qualify for cancellation, for example because you are relying on a new appraisal of a value that has risen, a refinance into a loan with under 80% LTV is another way out.
Before you decide, compare what you are being offered against national averages. Freddie Mac’s Primary Mortgage Market Survey (PMMS) publishes average rates weekly. Rates move, so a quote that beat the average last month may not today. For the broader question of timing, our should-I-refinance-now and cash-out versus HELOC guides go deeper.
Mortgage Refinancing FAQ
What is mortgage refinancing in simple terms?
Mortgage refinancing is taking out a new home loan to pay off your existing one. The new loan has its own rate, term, and closing costs, and it replaces the old mortgage completely.
Is refinancing the same as a loan modification?
No. A modification changes the terms of your existing loan through your current servicer, usually due to hardship. A refinance creates a new loan that pays off the old one.
How much does it cost to refinance a mortgage?
Costs include lender fees, appraisal, title and settlement services, recording fees, and prepaid items. The exact total is itemized on your Loan Estimate and varies by lender, loan size, and state.
How do I calculate my refinance break-even point?
Divide your total closing costs by your monthly savings. For example, $6,000 divided by $197 is about 30.5 months, so break-even lands near month 31.
Does refinancing hurt your credit score?
A full application involves a hard credit inquiry, which can cause a small, temporary dip. A soft-pull pre-qualification does not affect your score.
What is the difference between rate-and-term and cash-out refinancing?
Rate-and-term changes your rate or term without meaningful cash back. Cash-out increases your loan balance and pays you the difference. As of 2026, conventional cash-out is capped at 90% LTV, and VA cash-out allows up to 100% LTV.
What is a streamline refinance?
A streamline is a reduced-documentation refinance for borrowers with an existing FHA or VA loan, such as the FHA Streamline or the VA IRRRL. It often skips the appraisal and requires less paperwork.
Can I refinance to remove PMI?
Yes. If your home value has grown so your new loan is under 80% LTV, refinancing can eliminate PMI on a conventional loan. You may also be able to cancel PMI without refinancing once you reach 80% of the original value.
How long does a refinance take?
Timelines vary with appraisal scheduling, document turnaround, and underwriting. Many refinances close in roughly a month or so, but your own timeline may be shorter or longer.
Is Duane Buziak a mortgage broker or a mortgage lender?
Both. Duane Buziak is a broker who shops hundreds of wholesale lenders to find the best fit for your file, and he also has in-house and correspondent funding capability when that route serves the borrower better.
Run Your Own Numbers Before You Trust a Rate Headline
Refinancing is a math decision, not a rate headline. A lower rate can still cost you if you sell early, restart a long term, or pay high closing costs, and a modest drop can be a great deal if you stay put and the break-even arrives quickly. Get your closing costs and monthly savings in writing, divide one by the other, and compare the result to how long you plan to keep the loan.
