A $450,000 mortgage locked at 6.50% for 30 years carries an estimated principal-and-interest payment of $2,844. If rates move to 6.75% before you lock, that payment rises to about $2,919 – a $75 monthly difference and roughly $4,500 over the first five years. Taxes, insurance, and mortgage insurance are separate, but this is why a rate lock deserves more attention than a quick yes or no.
This guide to mortgage rate locks is for buyers who want to protect a payment without locking too early. That decision can feel especially consequential on a larger-lot Goochland purchase, a Manakin-Sabot move-up home, or a construction timeline that has more variables than a standard resale closing.

What a Mortgage Rate Lock Actually Does
A mortgage rate lock is a commitment from the mortgage broker’s selected wholesale option to hold a specific interest rate and pricing for a defined period while your loan is processed. It protects you against a rate increase during that window, assuming the information used to structure the loan remains materially the same.
A lock is not simply a promise that one number will appear at closing. Your final terms can change if the loan itself changes. For example, a lower appraisal that increases your loan-to-value ratio, a credit score change, a new debt payment, a switch from owner-occupied to investment use, or a different closing date may require repricing.
Duane Buziak, NMLS #1110647, helps borrowers look beyond the headline rate to the payment, cash needed at closing, lock expiration date, and program fit. A lower rate that requires more upfront discount points is not automatically the better choice if you expect to sell or refinance in a few years.
When Should You Lock Your Mortgage Rate?
The practical answer is: lock when you have a property under contract, a payment you are comfortable with, and enough confidence in the closing timeline. Trying to identify the absolute bottom of the market is usually speculation, not a financing strategy.
For a conventional purchase, many buyers choose a 30- to 45-day lock after contract ratification. That often fits a typical appraisal, underwriting, and closing process. If your contract has a 21-day settlement date, the shorter timeline may call for a 15- to 30-day lock. If you are building a home near Oilville or purchasing a property that needs septic, well, survey, or repair work, a longer lock may be worth considering.
The right timing depends on the cost of the lock, the size of the loan, your risk tolerance, and how solid the transaction timeline is. A buyer borrowing $250,000 may view a modest rate movement differently than a buyer financing $750,000 near the 2026 one-unit conforming loan limit of $832,750 in Goochland County.
Do Not Lock Before the Loan Details Are Solid
Before locking, confirm the purchase price, loan amount, occupancy, property type, estimated closing date, and intended loan program. This matters for homes with acreage west of Richmond. A property that looks conventional at first may need closer review if it has agricultural use, an unusual outbuilding, a private road agreement, or appraisal complexity.
USDA buyers across Goochland, Powhatan, Louisa, Fluvanna, and Cumberland should also verify property eligibility and household-income considerations early. A USDA transaction can offer a strong zero-down path for eligible buyers, but its timeline should be reflected in the lock plan rather than assumed.
Lock Periods, Pricing, and Extensions
Longer lock periods generally cost more because the wholesale market must hold that pricing for more time. A 15-day lock may price more favorably than a 45-day lock, while a 60-day or 90-day lock can be useful when the contract and underwriting timeline genuinely require it.
Ask to see the trade-off in dollars. On a $450,000 loan, paying 0.125% in discount points equals $562.50. That may be reasonable if it provides a meaningful rate improvement, but it should be evaluated against your expected time in the home. Closing costs for Virginia purchase transactions often run roughly 2% to 5% of the purchase price before any seller credits, prepaid items, or program-specific charges. Ask about our no-out-of-pocket closing options if cash management is a priority.
Extensions are sometimes available when a closing moves beyond the lock expiration date. They are not automatic, and their cost can vary with market conditions and the length of the extension. The best protection is not always buying the longest lock. It is setting a realistic contract schedule, promptly providing documentation, and addressing appraisal or title questions early.
What If Rates Fall After You Lock?
A rate lock is primarily downside protection. If rates rise, your locked rate remains protected as long as the loan remains eligible and closes before expiration. If rates fall, you generally do not receive the lower rate automatically.
Some pricing structures may offer a float-down feature, which can allow a one-time adjustment under specific conditions. Float-down availability, timing rules, and fees vary. It is worth discussing before the lock is placed, not after the market moves.
A borrower should not assume that cancelling and relocking will produce better pricing. Rules may limit that option, and restarting with a different wholesale source can introduce new timing risk. A clear lock strategy is more valuable than chasing every daily market headline.
Local Details That Can Affect a Lock Timeline
Goochland County’s higher-priced, lower-density market can create appraisal timing considerations, particularly for custom homes, acreage, and properties with few closely comparable sales. That is one reason a 30-day lock may be too tight for some purchases, even if the contract date looks straightforward.
For jumbo financing, reserve requirements can also shape the file. Depending on credit, assets, occupancy, and property profile, borrowers may need six to 12 months of total housing-payment reserves. Conventional financing commonly starts around a 620 credit score, though stronger pricing typically comes with stronger credit and a lower debt-to-income profile. VA financing has no government-set minimum score, while many VA options use practical score benchmarks around 580 to 620 depending on the file.
A responsive broker can match the lock period to the actual transaction instead of forcing every borrower into one timeline. That is particularly useful for self-employed buyers using bank statements, investors using DSCR financing, and buyers whose income or assets require additional review.
Mortgage Rate Lock Comparison
| Lock choice | Typical use | Pricing trade-off | Primary risk | Best fit |
|---|---|---|---|---|
| 15-30 days | Fast, clean resale closing | Often lower cost | Expiration if appraisal or documents are delayed | Well-prepared buyers with short settlement dates |
| 30-45 days | Typical conventional, FHA, or VA purchase | Balanced | Moderate exposure to a longer-than-expected file | Most standard Richmond-area purchases |
| 60-90 days | Complex appraisal, new construction, or rural property | Usually higher cost | Paying for time you do not use | Acreage, well/septic, or extended construction timelines |
| Float-down feature | Borrower wants some flexibility if rates improve | May carry a fee or stricter terms | Not qualifying for the adjustment | Buyers who value certainty but want defined upside |
Frequently Asked Questions About Mortgage Rate Locks
1. Is a mortgage rate lock guaranteed?
It protects the agreed pricing through the expiration date if your loan details, qualifications, and closing timeline remain consistent with the locked file.
2. Can I lock a rate before finding a house?
Usually, a purchase lock is tied to a specific property and contract. A pre-approval can estimate pricing, but it does not replace a property-specific lock.
3. How long should my rate lock be?
Choose a period that matches the realistic closing schedule, with extra care for rural properties, complex appraisals, new construction, or documentation-heavy income files.
4. Does a rate lock affect my credit score?
The lock itself does not create a new credit inquiry. Credit review requirements are separate from the lock decision.
5. Can Goochland Mortgage help me compare lock options?
Yes. A broker can explain the payment difference, points, estimated cash impact, expiration date, and extension risk before you commit.
6. What happens if my appraisal comes in low after I lock?
The purchase price, down payment, or loan structure may need to change. That can affect pricing, so discuss the options promptly before the lock expires.
7. Are USDA loans eligible for rate locks?
Yes. Eligible USDA purchases can be locked, but the lock should allow enough time for property review and program processing.
8. Is Goochland Mortgage legitimate for VA and conventional financing?
Goochland Mortgage is a Virginia-based brokerage led by Duane Buziak, NMLS #1110647, serving purchase, refinance, rural, investment, and specialty financing needs with personalized guidance.
