Picture this: you’re a first-time buyer in Short Pump or Glen Allen, and after months of searching, you finally find the home. The seller accepts your offer. Your broker quotes you a rate that makes the monthly payment work. You feel good. Then, over the next 30 days while inspections, appraisals, and title work unfold, you watch market rates tick upward — and suddenly the payment you budgeted for no longer matches the number on your closing disclosure.
This is not a hypothetical. It happens regularly in active markets, and it is exactly the scenario a mortgage rate lock is designed to prevent. Understanding how rate locks work — and how to use them strategically — is one of the most practical things a Henrico County homebuyer can do before signing a purchase contract.
This guide is written primarily for Segment B buyers: general and first-time buyers navigating the purchase process for the first time. But the mechanics and strategy apply equally to move-up buyers in Wyndham, Twin Hickory, or anywhere along the River Road corridor. What follows is a plain-language explanation of what a mortgage rate lock is, how long it should last, what it costs when things go sideways, and why the lender structure you choose — broker versus single-shelf direct lender — affects your lock options more than most buyers realize.

How a Rate Lock Actually Works — And What It Protects You From
A mortgage rate lock is a written agreement between the borrower and the investor (executed through your mortgage broker) that freezes a specific interest rate and its associated discount points and fees for a defined period of time. It is tied to a specific loan amount, a specific property, and a specific borrower profile. It is not a loan approval. It is a pricing guarantee.
According to the Consumer Financial Protection Bureau, a rate lock protects you from rising interest rates while your loan is being processed. Once locked, if market rates climb above your locked rate, you still close at the rate you agreed to. That protection has real dollar value in a volatile rate environment.
What a rate lock does not protect you from is the downside of a rate drop. If you lock at 6.75% and rates fall to 6.50% two weeks later, you are generally still bound to your locked rate — unless you have a float-down option in writing, which is covered in a later section.
Lock periods are typically structured in 15-day increments: 15, 30, 45, or 60 days. The lock period must be long enough to cover the time between the lock date and the actual closing date — not the projected closing date, the actual one. This distinction matters enormously in Henrico County purchase transactions.
Consider the moving parts in a typical Henrico purchase: a title search can run 7 to 14 days; appraisal scheduling and completion can take 10 to 21 days depending on appraiser availability; HOA document review for communities like Wyndham or Twin Hickory can add another 3 to 10 days on top of that; and underwriting review adds additional time. Add it together and a 30-day lock is often uncomfortably tight. A 45-day lock is more realistic for most standard purchase transactions in this market.
Underestimating the lock window is one of the most common and costly mistakes buyers make. When a lock expires before closing, the borrower either pays to extend it or re-locks at current market pricing — whichever is less favorable is usually what happens under time pressure.
The rate lock is also conditional. It holds only as long as the loan profile remains materially the same. A significant change in credit score, a change in property type or occupancy designation, a change in loan amount, or a switch in loan program can all trigger a reprice or void the lock entirely. This is why mortgage professionals consistently advise buyers not to open new credit accounts, make large unexplained deposits, or change employment between lock and closing.
Timing Your Lock: Finding the Window That Fits Henrico Closings
Locking too early means paying for more days than you need — and if the deal falls apart before closing, you may lose the lock fee. Locking too late means rates may have moved against you before you act. The practical sweet spot for most Henrico purchase contracts is locking within 24 to 48 hours of a ratified contract, once the appraisal order and title search are already in motion.
To understand what is actually at stake, consider a worked example with real numbers.
On a $450,000 purchase with 10% down, the loan amount is $405,000. On a 30-year fixed mortgage, the difference between a rate of 6.75% and a rate of 7.00% produces the following:
At 6.75%: Monthly principal and interest payment of approximately $2,626.
At 7.00%: Monthly principal and interest payment of approximately $2,696.
Monthly difference: approximately $70 per month.
Over 30 years: approximately $25,200 in additional interest paid.
A 0.25% rate movement — the kind that can happen in a single week during a volatile bond market — costs this buyer roughly $25,000 over the life of the loan. That is not an abstract risk. That is the real cost of delaying a lock decision while waiting to see if rates improve.
Here is where lender structure becomes directly relevant. A single-shelf direct lender has one pricing shelf — they can only lock what their one investor offers on that particular day. If that investor’s lock pricing is unfavorable, the buyer has no alternative through that lender.
A mortgage broker working through a wholesale network like Coast2Coast can compare lock terms, pricing, and float-down availability across multiple investors on the same day. This means the broker can identify which wholesale shelf offers the most favorable lock pricing at the moment the buyer is ready to lock — not just what one investor happens to be offering. That structural advantage is worth understanding before you choose who to work with.
Lock Periods, Extension Costs, and the Float-Down Option
Not all lock periods are created equal, and the right one depends on your specific transaction. Here is how the standard windows map to common Henrico purchase scenarios:
15-day lock: Rare. Used only when closing is imminent and the file is fully through underwriting. Not practical for most purchase transactions.
30-day lock: Standard for smooth, straightforward transactions where the appraisal is ordered quickly and no contingencies are expected to cause delays. Tight for most Henrico purchases but workable in ideal conditions.
45-day lock: Recommended for most Henrico purchase transactions involving appraisal contingencies, HOA document review, or any complexity in the title search. This is the practical default for buyers in communities like Wyndham, Twin Hickory, or Lakeside.
60-day lock: Appropriate for new construction in the Short Pump or Glen Allen corridors, complex loan files, or situations where the builder’s completion timeline is uncertain. Longer locks cost more — typically priced as additional basis points or a slightly higher rate.
Lock extensions become necessary when closing is delayed past the original lock expiration. Extensions are not free. Depending on market conditions and the specific investor, an extension typically costs between 0.125% and 0.375% of the loan amount per 15-day increment. On a $405,000 loan, that translates to approximately $506 to $1,519 per extension window. Buyers should budget for this possibility, particularly in transactions with appraisal disputes or inspection renegotiations that push timelines out.
Float-down options are a separate feature that some investors offer. A float-down provision allows the borrower to capture a lower rate if market rates drop by a defined threshold — often 0.25% or more — after the lock is in place. The mechanics vary by investor: some require a formal request submitted within a specific window before closing, some charge an upfront premium, and some build the cost into a slightly higher base rate.
Float-downs are not universally available. A broker working across multiple wholesale investors can identify which shelves offer this feature and compare the terms. A single-shelf direct lender can only offer a float-down if their one investor happens to provide it. For buyers who want both the protection of a lock and the ability to benefit from a rate improvement, the broker’s access to multiple shelves is directly relevant to whether this option is even on the table.
What Can Break a Rate Lock — and How to Protect Yours
A rate lock is a conditional guarantee, and the conditions matter. Several borrower-side changes can void or reprice a lock mid-process, and buyers are often surprised to learn how many of these triggers are within their own control.
Credit score changes: A meaningful drop in credit score between lock and closing can trigger a reprice. This is why buyers are advised to avoid opening new credit accounts, applying for new financing, or doing anything that generates hard credit inquiries during the loan process.
Large or unexplained deposits: Underwriters are required to source all funds used for closing. A large deposit that cannot be documented can delay closing and, if it pushes the lock window, create extension costs or repricing exposure.
Employment changes: Switching jobs, moving from salaried to self-employed income, or taking a leave of absence between lock and closing can require the file to be re-underwritten under different income guidelines. This can void the lock or require a program change.
Loan amount changes: If the purchase price is renegotiated downward — often triggered by an appraisal that comes in below contract price — the loan amount changes, and the lock may need to be re-evaluated. Buyers in Tuckahoe, Deep Run Park, or other Henrico neighborhoods with active price appreciation should be aware that appraisals can lag market movement, creating a gap between contract price and appraised value.
Program changes: Switching from a conventional loan to an FHA loan, or changing occupancy designation, constitutes a material change to the loan profile and typically requires a new lock.
On the lender side, delays caused by the lender rather than the borrower are a different matter. When a lender’s back-office processing causes a closing to miss the lock window, most investors will extend the lock at no cost to the borrower — but this requires someone to advocate for that outcome. A mortgage broker working on the borrower’s behalf has more direct leverage to push for a no-cost extension in lender-caused delay situations than a borrower dealing directly with a retail lender’s back-office team.
Rate Lock vs. Float: When Floating Makes Sense (and When It Doesn’t)
Floating means deliberately choosing not to lock — accepting market rate risk in the hope that rates will fall before closing. It is a calculated gamble, not a strategy, and it is appropriate in a narrow set of circumstances.
Floating may make sense when: the buyer has a very short closing timeline of under 15 days and the file is already through underwriting; market signals from Federal Reserve communications or bond market movement strongly suggest rates are trending downward; or the buyer has a confirmed float-down option in writing that provides a defined floor on the downside risk.
For most Henrico first-time buyers and move-up buyers, floating is not advisable. The cost of a rate increase — measured in monthly payment and lifetime interest, as illustrated in the worked example above — almost always outweighs the potential savings from a modest rate drop. A buyer floating without a float-down option is taking on uncapped upside risk for a capped potential benefit.
There is also a practical budgeting argument for locking. A locked rate allows the buyer to calculate their exact monthly principal and interest payment, which feeds into accurate budgeting for property taxes, homeowner’s insurance, and HOA fees. In communities like Innsbrook or along the River Road corridor, where HOA structures and fee levels vary considerably, knowing your fixed housing costs before closing is not just convenient — it is necessary for responsible financial planning.
The broker’s role in this decision is advisory. Duane Buziak, helping Henrico families navigate the mortgage process since 2014 and based in Glen Allen, can walk through the current rate environment, explain the specific lock options available across the wholesale shelf at that moment, and help a buyer make an informed decision based on their timeline, risk tolerance, and loan type. That conversation is available before any credit pull — which brings us to the next section.
Rate Lock Options Across Lender Structures: A Direct Comparison
| Feature | Duane Buziak / Coast2Coast (Broker) | Single-Shelf Direct Lender | Why It Matters |
|---|---|---|---|
| Lock Shopping Ability | Can compare lock pricing and terms across multiple wholesale investors on the same day | Limited to one investor’s pricing shelf on any given day | More investor options means the ability to identify more favorable lock pricing at the moment you’re ready to lock |
| Float-Down Availability | Can identify which wholesale investors offer float-down provisions and compare terms | Float-down only available if the single shelf offers it | Buyers who want downside protection without giving up rate improvement potential need access to investors who offer this feature |
| Extension Negotiation Leverage | Broker advocates directly on borrower’s behalf with investor; can push for no-cost extensions in lender-caused delays | Borrower deals with retail back-office; limited direct leverage | In a delayed closing, who is advocating for you matters — especially when extension costs run $500–$1,500 per window |
| Pre-Lock Credit Pull | NoTouch Credit Pull pre-qualification available — no credit score impact before locking | Typically requires a hard credit pull to provide rate quotes | Buyers can understand their rate range and lock readiness without affecting the credit score that determines their rate |
| Lock Period Flexibility | Access to 15, 30, 45, and 60-day lock periods across multiple investors; can match the right period to the transaction | Lock period options limited to what one investor offers | Mismatched lock periods create extension costs; matching the right window to the transaction from the start saves money |
8 Questions Henrico Buyers Ask About Rate Locks
1. What is a mortgage rate lock? A mortgage rate lock is a written agreement between a borrower and the investor (executed through your mortgage broker) that freezes a specific interest rate and associated fees for a defined period, typically 15 to 60 days. It guarantees your rate will not increase if market rates rise before closing, as long as the loan profile remains materially the same.
2. When should I lock my rate? For most Henrico purchase transactions, the practical window is within 24 to 48 hours of a ratified contract, once the appraisal order and title search are in motion. Locking too early means paying for days you may not need; locking too late means absorbing market movement that may have already worked against you.
3. How long should my lock period be? A 45-day lock is the practical recommendation for most standard Henrico purchase transactions, accounting for appraisal scheduling, HOA document review in communities like Wyndham or Twin Hickory, and title search timelines. New construction in the Short Pump or Glen Allen corridors typically warrants a 60-day lock.
4. What does a rate lock extension cost? Lock extensions are priced by the investor, typically in the range of 0.125% to 0.375% of the loan amount per 15-day increment. On a $405,000 loan, that is approximately $506 to $1,519 per extension window. These costs are real and buyers should plan for the possibility.
5. Can I get a lower rate if rates drop after I lock? Only if you have a float-down option in writing, and only if rates drop by the defined threshold specified in that agreement — often 0.25% or more. Float-down provisions are not universally available and typically carry an upfront cost or a slightly higher base rate. A broker can identify which investors offer this feature.
6. Does locking a rate affect my credit? The rate lock itself does not affect your credit. The credit inquiry associated with your mortgage application does. Duane Buziak at Coast2Coast offers a NoTouch Credit Pull pre-qualification that allows buyers to understand their rate range and lock readiness without a hard credit pull impacting their score.
7. What happens if my closing is delayed past my lock expiration? If the delay is caused by the borrower or by transaction complexity, an extension will typically be required at the borrower’s cost. If the delay is caused by the lender’s processing, most investors will extend at no cost — but this outcome requires someone to advocate for it. A broker working on your behalf has direct leverage in this conversation that a retail borrower dealing with a back-office team does not.
8. Can a broker get me a better lock than a direct lender? A broker working through a wholesale network can compare lock pricing, float-down availability, and extension terms across multiple investors on the same day. A single-shelf direct lender can only offer what their one investor prices that day. More options means more ability to identify favorable lock terms — that is the structural advantage of the broker model.
Putting It All Together: Your Rate Lock Action Plan for Henrico
A mortgage rate lock is not paperwork. It is a financial decision with real dollar consequences — consequences that, as the worked example above shows, can total tens of thousands of dollars over the life of a loan. For buyers in Short Pump, Glen Allen, Wyndham, or anywhere across Henrico County, understanding when to lock, how long to lock for, and which lender structure gives you the most flexibility is not optional knowledge. It is the foundation of a well-executed purchase.
The right approach starts before you are even ready to lock. Understanding your rate range, your loan options, and your likely closing timeline before you make an offer positions you to act decisively when the moment comes. That process begins with a pre-qualification — and it does not have to cost you a credit inquiry to get there.
Duane Buziak at Coast2Coast Mortgage offers a NoTouch Credit Pull pre-qualification for Henrico buyers who want to understand their options without any impact to their credit score. It is the first step toward knowing your rate range, your lock strategy, and what you can realistically budget for a home in this market.
