A mortgage rate lock is the moment your interest rate stops being a moving target. For Henrico County buyers watching daily rate swings while shopping in Short Pump, Glen Allen, or Twin Hickory, knowing exactly when and how to lock can mean the difference between a payment you planned for and one that surprises you at closing. By the end of this guide you’ll know what a rate lock actually protects, how long to lock for, and how to avoid the timing mistakes that cost buyers real money. You’ll want a signed purchase contract (or a refinance application already in process) and a loan officer reviewing your file before you start.

Step 1: Understand What a Rate Lock Actually Guarantees
A rate lock is a written agreement between you and your broker’s lending partner that freezes your interest rate for a set period, commonly 15, 30, 45, or 60 days, while your loan moves through processing and underwriting. Once locked, the rate itself won’t change due to normal market movement, even if bond yields swing the following week.
What a lock does not do is freeze everything else about your loan. Your loan amount, discount points, and final closing costs can still shift if your purchase price changes, you adjust your down payment, or new information appears in underwriting. A lock protects the rate tied to your file at that moment, not every number on your Loan Estimate. If your file changes materially after locking, your broker may need to re-verify the terms.
A common misconception among first-time buyers is that pre-qualification or pre-approval locks a rate. It doesn’t. Duane Buziak’s credit-safe pre-qualification process uses a soft credit pull to show you what you likely qualify for and at what approximate rate range, without affecting your credit score. That’s a planning tool. The actual rate stays floating, meaning it moves with the market, until you and your loan officer formally request a lock on a specific loan file tied to a specific property or refinance application. Understanding that distinction upfront prevents a frustrating surprise later: buyers sometimes assume the number they saw during pre-qualification is guaranteed, then find the market has moved by the time they’re under contract weeks later. Treat pre-qualification as your starting point for budgeting and house-hunting in areas like the River Road corridor or Wyndham, not as a locked-in number.
Step 2: Get Your File Loan-Ready Before You Watch Rates
Locking a rate only matters if you’re in a position to actually close within the lock window. That means your file needs to be substantially complete, income documented, assets verified, and, for a purchase, a signed contract in hand, before you start paying close attention to daily rate movement.
For most Henrico purchases, the practical timeline starts once your offer is accepted on a home, whether that’s a resale in Glen Allen, new construction near Twin Hickory, or a condo closer to Innsbrook, and your ratified contract is in your loan officer’s hands. At that point your lender can quote real lock terms against a real closing date, rather than a hypothetical one.
The mistake to avoid is locking a rate while you’re still searching for a home. A lock has a hard expiration date. If you lock during your search and it takes three more weeks to find a house and get an offer accepted, you’ve burned through part or all of your lock window with no closing to show for it. Some buyers try to time the market this way, hoping to catch a favorable rate before they’ve even found a property, and end up either paying an extension fee or relocking at a worse rate later. Wait until you have a contract, then move quickly to get your file loan-ready:
- Pay stubs, W-2s or tax returns, and bank statements submitted and verified
- Purchase contract fully executed and delivered to your loan officer
- Any credit issues or large deposits already explained in writing
- Homeowners insurance quote requested so it doesn’t hold up underwriting
Once those pieces are in place, you’re ready to have a real conversation about lock length.
Step 3: Decide on a Lock Period That Matches Your Closing Date
Lock periods aren’t one-size-fits-all. The right length depends on how much time realistically sits between today and your closing date, plus a cushion for anything that might slip.
A standard 30-day purchase contract in Henrico usually pairs well with a 30 or 45-day lock. Refinances, which often involve appraisal scheduling and title work that can take longer than a purchase, commonly run on 45 or 60-day locks. Shorter locks, in the 15 to 30-day range, typically price slightly better than 60 or 90-day locks because the lender is assuming less rate risk over a shorter window. That pricing difference is real but often modest, and it should never be the deciding factor if it means cutting your timeline too close.
Build in a buffer. Appraisal turnaround and title work in Henrico County can run longer than expected depending on the season and the specific title company handling your closing. If your contract calls for a 30-day close, locking for exactly 30 days leaves zero room for a delayed appraisal, a title issue on an older home near Lakeside, or a lender conditions request that takes a few extra days to satisfy. Locking for 45 days on a 30-day contract costs a small amount in pricing but buys real protection against the kind of routine delays that happen on a meaningful share of purchase transactions. Ask your loan officer to show you the pricing difference between the exact-match lock and the next tier up before deciding; the gap is often small enough that the peace of mind is worth it.
Step 4: Compare Locking Now vs. Floating the Rate
Floating means staying unlocked, which is a bet that rates will improve before you commit. There’s a real upside if the market moves in your favor: you lock later at a lower rate with no downside. But the risk cuts both ways. If rates rise while you’re floating, you absorb that increase on the day you finally lock, and there’s no mechanism to undo it.
Locking removes that uncertainty. For a specific home purchase, say a property under contract in Short Pump, a locked rate lets you calculate your exact monthly payment and move forward with budgeting, furniture shopping, and moving logistics without wondering whether your payment will be higher by closing. For many buyers, especially those stretching to afford a specific home, that certainty matters more than the small chance of catching a slightly better rate.
Rather than guessing, ask your loan officer for a same-day comparison across lock terms: what does the rate look like locked today for 15, 30, and 45 days, versus floating with a plan to lock in a week? Real numbers from your actual file, current on the day you’re deciding, give you something concrete to weigh instead of a general sense of where the market “might” be headed. Market forecasts are not guarantees, and no one, including your loan officer, can reliably predict short-term rate movement. The decision to lock or float should rest on your tolerance for risk and your closing timeline, not on a prediction. If your closing date is firm and near, locking removes a variable you don’t need. If you have real flexibility and are comfortable with the downside, floating for a short, defined period with a plan to lock by a specific date can make sense.
Step 5: Request the Lock and Get It in Writing
Once you decide to lock, confirm it verbally with your loan officer, then require written confirmation showing the exact rate, any points paid, the lock date, and the expiration date. A verbal confirmation isn’t enough protection if a question comes up later; the written lock confirmation is your proof of the terms you were promised.
Consider a worked example. On a $450,000 loan, locking at 6.375% for 30 days versus floating and ultimately closing at 6.5% works out to roughly $42 more per month in principal and interest, and over $15,000 in additional interest paid across a full 30-year term. These figures are illustrative: verify the actual rate spread and payment difference with your loan officer at the time you lock, since rates and pricing shift daily. The point isn’t the specific numbers, it’s that even a modest rate difference compounds meaningfully over the life of a loan, which is exactly why locking in writing matters once you’ve settled on terms you’re comfortable with.
After you receive your written lock confirmation, cross-check it against your Loan Estimate, the standardized federal disclosure your broker is required to provide. The Consumer Financial Protection Bureau’s Loan Estimate explainer walks through what each section of that document means and what should match your locked terms. If the rate, points, or fees on your lock confirmation don’t line up with your Loan Estimate, flag it with your loan officer immediately rather than waiting until closing disclosure to sort it out.
Step 6: Monitor the Lock Through Underwriting and Closing
A rate lock isn’t something you set and forget. Track your lock expiration date against your actual closing date throughout underwriting, and flag your loan officer the moment either one shifts. Closing dates move for reasons that have nothing to do with your loan, a seller’s move-out timeline, a delayed appraisal, or a title issue, and any of those can push you past your lock window if you’re not watching it.
If closing slips past your lock expiration, most lenders charge a per-day or per-week extension fee to keep the original rate in place rather than forcing a relock at current market pricing. That fee schedule varies by lender and loan program, so ask for it upfront when you lock, not after you’ve discovered you need an extension. Knowing the cost in advance lets you weigh a short extension against the alternative of relocking, which could mean a better or worse rate depending on where the market has moved.
A common misconception is that once locked, the rate is permanent no matter what else changes about the loan. That’s not accurate. If your loan amount changes, you switch loan programs, your credit profile changes materially, or your file requires a different product than originally underwritten, your broker may need to relock or requote terms. This is uncommon when a file stays clean, but it happens often enough that you shouldn’t assume immunity. Keeping your financial picture stable between lock and closing, no new credit accounts, no major purchases, no job changes, is the best way to protect the terms you locked in.
Step 7: Know Your Options If Rates Drop After You Lock
Locking protects you from rates rising, but it also means you generally give up the benefit if rates fall after you commit. Some lock agreements include a float-down provision: a one-time option to reduce your locked rate if market rates drop significantly before closing, often available for a fee or built into certain loan programs.
Float-down provisions are not automatic and not universal. Terms vary by lender and by loan file, so confirm before you lock whether your specific agreement includes this option, what threshold of rate improvement triggers it, and what it costs, if anything. Some borrowers assume every lock includes this protection; many don’t, and asking after the fact is too late.
If your lock doesn’t include a float-down and rates fall meaningfully after you close, a refinance remains a separate option down the road. It’s a different transaction with its own costs and qualifying process, worth a conversation with your loan officer if the market shifts enough to make it worthwhile, but it’s not something to count on at the time you lock. Treat your lock decision based on where rates stand today and your tolerance for missing a future dip, not as a placeholder you plan to unwind.
