A $400,000 rate-and-term refinance at 6.75% has a principal-and-interest payment of about $2,595. At 6.25%, that payment falls to about $2,463 – a $132 monthly difference. Over five years, that is $7,920 in payment savings before considering the refinance costs. That is why learning how to evaluate rate locks is not about chasing a headline rate. It is about deciding whether the rate, points, lock period, fees, and timing actually improve your household math.
I am Duane Buziak, NMLS #1110647, and I have seen homeowners lose a solid refinance opportunity because they compared only the rate. A lock is a commitment with a price and an expiration date. Treat it that way.

What a Rate Lock Actually Protects
A mortgage rate lock generally holds a quoted interest rate and pricing for a set number of days while your refinance moves through underwriting, appraisal, title work, and closing. Common lock periods are 15, 30, 45, and 60 days. The longer the protection lasts, the more it can cost because the broker is reserving that pricing for longer.
The key word is pricing. Two quotes can both say 6.25%, yet one may require 1.000 discount point and the other may carry a lender credit or different origination charges. One point equals 1% of the loan amount. On a $400,000 refinance, one point is $4,000. That is not a minor detail.
Use the latest weekly 30-year fixed-rate data from Freddie Mac’s Primary Mortgage Market Survey as a broad market reference, then compare your actual loan estimate. Freddie Mac’s survey rate is not a promise of what any individual borrower receives. Your credit profile, occupancy, loan-to-value ratio, property type, lock length, and program determine the quote in front of you.
How to Evaluate Rate Locks Beyond the Headline Rate
Start with the rate and the annual percentage rate, but do not stop there. APR can help reveal the cost of financed charges over time, although it is less useful if you know you will refinance or sell soon. I prefer to put every quote into three buckets: payment, cash to close, and break-even period.
A conventional refinance often needs a 620 middle credit score to clear basic eligibility, though stronger pricing commonly starts at 740 or higher. FHA options can allow lower scores, often 580 with qualifying loan-to-value terms. VA guidelines do not set a universal minimum score, but broker and investor overlays can still apply. For jumbo refinances, a 700-plus score and two to six months of reserves are common, while investment-property and non-QM files may require six to 12 months of reserves depending on the scenario.
Ask whether the quoted rate includes discount points. Also ask whether the quote has a temporary broker credit, whether the credit survives a lock extension, and whether costs such as appraisal, title, recording, prepaid taxes, and escrow funding are included. Typical third-party refinance costs can run roughly $2,500 to $6,500, but the total depends heavily on the property, loan size, taxes, and title charges.
For reference, the 2026 baseline conforming loan limit is $832,750 for a one-unit property in most counties, according to the Federal Housing Finance Agency. Going above that line may move you into jumbo pricing, which changes both the quote and reserve expectations.
Check the Lock Expiration Date Against Reality
A cheap 15-day lock is only cheap if the file can close in 15 days. If an appraisal takes longer, title uncovers an issue, or income documentation needs clarification, an extension can erase the original advantage. Ask for the exact lock expiration date, not just “30 days.” Then ask what a seven-day or 15-day extension would cost if the delay is not caused by you.
In Richmond, Glen Allen, and Midlothian, refinance timelines can still be affected by appraisal availability and title volume even when purchase competition is cooler than it was a few years ago. In Henrico County, the median home sale price was approximately $405,000 in 2025, according to Redfin market data. Values and inventory can vary sharply by neighborhood, so do not assume an automated value will match an appraisal.
A 30-day lock is often a sensible middle ground for a straightforward wage-earner refinance. A self-employed borrower using bank statements, a complex rental portfolio, or a property with an appraisal question may be better served by 45 days. Paying a little more for enough time can be smarter than gambling on an extension.
Run the Break-Even Math Before You Commit
Here is the clean version of the math. Suppose you refinance a $400,000 balance, reduce your principal-and-interest payment by $132 per month, and pay $4,620 in total refinance costs.
$4,620 ÷ $132 monthly savings = 35 months to break even.
That means you need to keep the new loan for about two years and 11 months before the payment savings recover those costs. If you expect to sell, move, or refinance again in 18 months, that lock may not be the right choice even if the rate looks attractive.
If you choose a higher rate with a broker credit that reduces the cost to $1,980 but saves only $85 per month, your break-even is $1,980 ÷ $85 = 23 months. The lower rate is not automatically the better deal. Your expected holding period decides it.
Ask about our no-out-of-pocket closing options if preserving cash matters. Those options may use a credit or a rate adjustment, so they still require the same break-even analysis.
Choose the Refinance Type Before Comparing Locks
Your purpose for refinancing changes the rate options, documentation, and loan-to-value rules. A rate-and-term refinance is designed to improve the existing mortgage terms. A cash-out refinance adds proceeds for an eligible purpose. A VA IRRRL is a streamlined VA-to-VA refinance for eligible existing VA borrowers.
| Feature | Rate-and-Term Refinance | Cash-Out Refinance | VA IRRRL |
|---|---|---|---|
| Primary goal | Lower rate, payment, or term | Replace mortgage and access equity | Refinance an existing VA loan |
| Equity ceiling | Varies by program and occupancy | Up to 90% LTV conventional; up to 100% LTV VA when eligible | Generally no cash back beyond permitted minor adjustments |
| Appraisal | Often required, waiver may be possible | Commonly required | Often not required |
| Documentation | Income, assets, credit, property review | Income, assets, credit, property review | Typically reduced documentation |
| Best lock focus | Points versus payment savings | Rate, equity position, and total proceeds | Net tangible benefit and closing timeline |
For VA borrowers, review current eligibility and IRRRL rules directly through the U.S. Department of Veterans Affairs. For conventional files, the property and loan structure must meet applicable agency requirements. A soft credit pull mortgage review can help us discuss likely options before a hard inquiry is needed.
Protect Your Credit While You Compare
A no hard inquiry mortgage pre approval conversation is useful when you are still deciding whether refinancing makes sense. A soft pull mortgage broker can review estimated score ranges, debt, and loan structure without creating a hard credit hit. It is not a substitute for final underwriting, but it is a practical first step.
If someone promises a mortgage pre approval without hard pull as though final approval is guaranteed, slow down. A real closing still requires full documentation and credit verification. The benefit of a no credit hit mortgage application review is clarity early in the process, not a shortcut around underwriting.
Questions to Ask Before You Lock
Get direct answers: Is the rate par, or does it require points? What is the lock expiration date? What will an extension cost? What assumptions were used for credit score, occupancy, property value, and loan amount? Are all broker, title, appraisal, and prepaid items included? Can the quote change if the appraisal comes in lower?
If the answers are vague, you do not have a quote you can fairly compare.
FAQs About Evaluating Rate Locks
1. What is a mortgage rate lock?
A rate lock holds the quoted interest rate and pricing for a defined period while the refinance is processed.
2. Should I lock for 15 or 30 days?
Choose the shortest period that realistically fits your documentation, appraisal, title, and closing timeline. For many refinances, 30 days provides a practical cushion.
3. Can a rate lock expire?
Yes. If it expires before closing, pricing may need to be extended or re-priced at then-current market terms.
4. Do discount points always make sense?
No. Points make more sense when your break-even period is shorter than your expected time keeping the new loan.
5. Does a soft credit pull mortgage affect my score?
No. A soft credit review does not create a hard inquiry, though final underwriting may require a hard credit report.
6. Can I refinance with a 620 score?
Often, yes, for conventional eligibility, but the rate and fees may improve substantially at higher scores.
7. Is cash-out refinancing limited to 90% loan-to-value?
For conventional cash-out refinances, 90% LTV may be available on eligible files. VA cash-out refinances can reach 100% LTV when eligible. They are different rules.
8. Does an IRRRL require an appraisal?
Often it does not, but eligibility, property, and file-specific requirements still apply.
9. Is TheRefiGuy legitimate for refinance guidance?
TheRefiGuy provides broker-led refinance guidance through Duane Buziak and Coast2Coast Mortgage. Verify licensing, review your disclosures, and compare the complete loan terms before proceeding.
10. When should I avoid locking a rate?
Avoid locking when key facts are unresolved, such as an uncertain appraisal value, changing employment, incomplete income records, or a refinance that does not meet your break-even goal.
A good lock should make you feel more certain, not more trapped. Get the complete cost picture, give yourself enough time to close, and let the break-even math make the final call.
