A homeowner should refinance when the savings, or the goal being served, outweigh the closing costs within the time the new loan will actually be kept. The quickest check is a break-even calculation, followed by a comparison of real offers that does not trigger a hard credit inquiry. Duane Buziak, a broker who has been helping buyers find the right mortgage since 2014, built the free tool at Free Mortgage Search by Duane Buziak around that second step. It compares offers across hundreds of wholesale lenders using a NoTouch Credit Pull, a soft-pull comparison. The seven checks below run in the order a homeowner needs them, from defining the goal through locking the rate. Every rate and dollar figure in the examples is illustrative, not a live quote.
1. Name the Goal Before You Look at a Rate
A refinance can serve four different purposes: lowering the payment, changing the term, pulling out cash, or removing mortgage insurance. Each one defines a “good deal” differently, so a rate that suits one goal can undermine another. Without a stated goal, the lowest advertised rate wins by default, and it may not be the loan you needed.
Consider an illustration with two homeowners who each owe $250,000. The first wants breathing room in the monthly budget and chooses a 30-year term at an assumed 6.25%, for a principal and interest payment of about $1,539. Her total interest over the life of the loan would be roughly $304,000. The second wants the house paid off sooner and takes a 15-year term at an assumed 5.50%, for a payment near $2,043 and total interest of about $118,000. Neither is wrong. They are solving different problems, and each would judge the other’s loan a poor fit.
- Write the goal in one sentence, such as “Lower my payment by at least $150 a month” or “Be mortgage-free by age 60.”
- Attach a pass/fail test: a monthly savings target, a payoff date, a cash amount, or a loan-to-value level at which mortgage insurance ends.
- Keep that sentence next to every quote you review.
The common mistake is letting a low rate set the agenda, then accepting a longer term or higher costs that undercut the original reason for refinancing. To measure success, check whether the final offer meets your written test. If it does not, the rate is irrelevant.
2. Run the Break-Even Calculation With Real Numbers
Break-even is the number of months it takes for monthly savings to repay closing costs. Until you reach it, you are behind. After it, the savings are yours. The arithmetic is simple, which is why skipping it is so costly.
Suppose you owe $320,000 on a 30-year loan at 7.00%, with a principal and interest payment of about $2,128.96. A refinance at 6.25% on the same $320,000 gives a payment of about $1,970.30, which saves $158.66 a month. If closing costs total $6,400, divide: $6,400 ÷ $158.66 is about 40 months. If you expect to stay at least four years, the refinance pays for itself. If a job change could move you in two, it does not.
- Pull total closing costs from page 2 of the Loan Estimate, not from an advertised figure.
- Subtract the new principal and interest payment from the current one. Leave taxes and insurance out of both.
- Divide costs by monthly savings.
- Compare the result to the years you honestly expect to keep the home.
Two mistakes distort this math. The first is rolling costs into the loan and forgetting that the larger balance shrinks your savings. In the example, adding $6,400 makes the new balance $326,400, a payment of about $2,009.70, and savings of only about $119 a month. The second is assuming you will stay forever. Measure break-even months against your realistic years in the home, and treat anything beyond that horizon as a reason to pass.
3. Account for the Term Reset and Total Interest
A lower payment can hide a longer road. Refinancing into a fresh 30-year loan restarts the clock, so you can pay less each month and still pay more in total.
Take this illustration. A borrower is six years into a $320,000, 30-year loan at 7.00%. The balance is roughly $296,600, with 288 payments left, and remaining interest of about $316,500. She refinances that balance into a new 30-year loan at 6.25%. The payment drops to about $1,826, a relief of roughly $300 a month, but remaining interest rises to about $360,900. That is around $44,000 more, plus six more years of payments.
She has a better option. If she takes the same 6.25% loan but keeps paying the old $2,129 a month, the balance is gone in about 249 payments, roughly 39 months sooner than the old schedule, with total interest near $233,500. A lower rate can buy a shorter payoff, a lower payment, or some of each.
- Get your current payoff amount and remaining months from your servicer.
- Run both amortization schedules, old and new, and compare remaining interest.
- Test a shorter term, or set up extra principal payments equal to your old payment.
The common mistake is celebrating the monthly drop without checking lifetime interest. What to measure: total interest remaining under each loan, and the payoff date.
4. Check Your Equity, Credit, and Debt-to-Income Position
Three numbers decide which offers you will see and what they cost: loan-to-value (LTV), credit profile, and debt-to-income ratio (DTI). Checking them first prevents surprises after you have applied.
LTV is your balance divided by your home’s value. A $320,000 balance on a $400,000 home is 80%. That matters because conventional mortgage insurance is often removable or avoidable around that level, and a refinance can be one route to dropping it. Review the current Fannie Mae guidance for the exact rules, since seasoning and appraisal requirements apply.
- Estimate value conservatively, using recent comparable sales rather than an online guess.
- Divide your balance by that value.
- Pull your credit reports and dispute errors before applying.
- Add up monthly debt payments, including the new mortgage payment, and divide by gross monthly income to get DTI.
- Check the conforming loan limit for your county on the FHFA site. As of 2026, the national baseline is $832,750, with higher limits in high-cost areas, so verify your county’s figure.
The two common errors are applying before correcting credit report mistakes and overestimating value. An appraisal that comes in low can push you over an LTV threshold and change pricing or remove options. Track LTV percentage, credit score tier, and DTI against the thresholds for the programs you are considering.
5. Compare Offers Side by Side, Not Rate Against Rate
A rate is only one input. Points, lender credits, fees, and loan amount all change what you pay, which is why the Loan Estimate exists. Compare those documents line by line, not headline numbers.
Here are three illustrative offers on a $320,000 refinance, measured against a current payment of $2,128.96. Rates are assumed, not live quotes.
| Offer | Rate | Points or credit | Net closing costs | Monthly P&I | Monthly savings | Break-even | Net after 3 years |
|---|---|---|---|---|---|---|---|
| A | 6.00% | 1.5 points ($4,800) | $8,800 | $1,918.56 | $210.40 | about 42 months | -$1,226 |
| B | 6.25% | None | $4,400 | $1,970.30 | $158.66 | about 28 months | +$1,312 |
| C | 6.50% | $2,000 credit | $2,400 | $2,022.62 | $106.34 | about 23 months | +$1,428 |
The lowest rate, Offer A, loses for a three-year stay because the points take 42 months to recoup. At seven years, A and B finish nearly even, and A pulls ahead after that. The right offer depends on how long you will keep the loan. These figures are illustrations; read each offer’s actual APR from its Loan Estimate, since APR folds in costs that the rate alone leaves out.
- Request Loan Estimates on the same day, for the same loan amount, term, and lock period.
- Copy each into one table.
- Calculate break-even for each.
The common mistake is comparing quotes built on different points, lock periods, or loan amounts. Measure break-even months and APR across like-for-like offers only.
6. Use a Broker’s Wide Shelf and a Soft-Pull Comparison
A direct lender prices from its own single shelf. A broker can price the same borrower across hundreds of wholesale lenders, which widens the range of options to compare. Duane Buziak runs that comparison through the free tool with a NoTouch Credit Pull, so you can see offers without a hard inquiry.
Here is an illustration. Imagine one borrower profile priced two ways. A single direct lender quotes 6.375% with $4,900 in costs, a payment of about $1,996. A broker’s comparison returns several options, including 6.25% with $4,400 in costs, a payment of about $1,970. That is $26 less a month and $500 less upfront. It could easily go the other direction for another borrower. The value is in seeing the spread before deciding, not in assuming either route wins.
| Dimension | Single direct lender | Broker with wholesale access |
|---|---|---|
| Pricing sources | One company’s rate sheet | Many wholesale lenders priced against each other |
| Loan options | That company’s product menu | Programs from multiple lenders, matched to your goal |
| Credit check to compare | Varies by company | NoTouch Credit Pull soft-pull comparison |
| Underwriting | In-house, one set of guidelines | Placed with the lender whose guidelines fit your file |
| Cost to compare | Typically free to request a quote | Free through the comparison tool |
- Start a NoTouch Credit Pull comparison.
- Review the options against your written goal from step one.
- Take the strongest candidates forward as your Dare to Compare set: bring any quote you already hold and ask for a like-for-like match or better.
- Check that every rate shown has its APR beside it, and treat any rate without one as incomplete.
The common mistakes are treating a soft pull as a commitment, which it is not, and assuming the one familiar lender is the only place to look. Measure the number of like-for-like offers received and the cost spread between them.
7. Time Your Rate Lock and Closing Carefully
A rate lock holds your pricing for a set number of days. If closing slips past that date, you pay for an extension or reprice at current rates. The lock needs to cover the real timeline, not the hopeful one.
Imagine a file with a 30-day lock where the appraisal is scheduled late and the report comes back slowly. Day 30 arrives before closing, and an extension fee follows. A 45-day lock on the same file would have cost slightly more in pricing and avoided the fee entirely. Lock options commonly run from 30 to 60 days, though terms vary, so ask what is available.
- Ask for the lock length, extension cost, and any float-down terms in writing.
- Gather pay stubs, tax returns, bank statements, and insurance information before you apply.
- Respond to underwriting requests the same day.
- Review the Closing Disclosure when it arrives. Under current CFPB rules, you generally must receive it at least three business days before closing. For a refinance of your primary home, a three-business-day right of rescission after signing also generally applies. Confirm the details with the CFPB for your situation.
The classic mistake is locking short to save a small amount of pricing, then paying extension fees or losing the rate. Measure days from application to closing against lock length, and track any extension fees paid.
Where to Start, and What to Ask Next
Begin with strategies one and two. A written goal and a break-even figure take about twenty minutes and will screen out most refinances that should not happen. Then run a NoTouch Credit Pull comparison, and use Dare to Compare to test any quote you already hold against what comes back. If the numbers still pass your test, the remaining checks keep the loan from drifting off course.
If break-even lands past the time you will keep the home, or the goal is not met, the answer is simply not yet. Your current loan costs nothing to keep.
