A rate lock mortgage agreement is a written commitment from your broker’s investor to hold your interest rate and points for a set number of days, so market moves between contract and closing can’t raise your payment. What it does not do is protect your closing date. If the lock expires before you close, the price protection ends with it.
This article covers how locks work, what they cost, how to size the lock period for Stafford, Spotsylvania, and PCS-timed closings, and what your options are when closing slips.

How a Rate Lock Works Between Contract and Closing
Until you lock, your rate floats: it moves with the market, sometimes more than once a day. A lock freezes three things for a stated period: the interest rate, the points you pay (or the credit you receive), and the pricing tied to them. A Loan Estimate quote is only a snapshot of pricing on the day it was issued. It is not a lock unless the document says the rate is locked.
Lock periods are commonly 30, 45, or 60 days, and longer periods generally price a little higher because the investor carries more market risk. Exact pricing changes daily, so any figure you see is only good “as of” that day.
Consider a typical Stafford purchase. The contract is ratified on day 1. The loan is submitted, the appraisal is ordered and usually takes days to schedule and return, and underwriting issues a list of conditions. You clear those, the title company finishes its work, and the Closing Disclosure goes out. Most of those 30 to 45 days are spent waiting on third parties (appraisers, title, HOA or condo documents, employers), not on the loan itself. That is why a lock period should be built from the real path to the closing table.
The most common misconception is that a lock is an approval. It is not. A lock fixes pricing only. Your approval still depends on underwriting, the appraisal, and your finances staying the same, and your closing costs can still change for reasons unrelated to the rate. The CFPB’s page on what a mortgage rate lock is covers the definitions and the fact that terms and fees differ by company.
When to Lock: Floating, Locking Early, and the Soft-Pull Starting Point
A lock needs a property address, because pricing depends on the property type, occupancy, location, and loan amount. That is why most buyers lock after an accepted contract. Some lock at application when they already have the address, but without a property you can’t lock a rate, no matter how good today’s market looks.
Before the contract, the work is about numbers, not locking. Duane Buziak uses NoTouch Credit Pull to run a soft credit pull mortgage pre-approval, so you can see a payment range and your approval path before any hard inquiry hits your report. That gives you a realistic budget while you shop in Spotsylvania or King George, and the lock happens once there is a ratified contract.
Floating is a bet that rates will fall before you close. Nobody predicts rate moves reliably, and the downside is lopsided when your closing date is fixed. If the contract sets a settlement date, or your report date at Quantico is already on orders, a rate that rises costs you every month for the life of the loan, while a rate that falls only helps if you are still unlocked and flexible enough to act on it.
Two mistakes come up repeatedly:
- Locking before the deal is solid. If the contract is still in a due diligence window or the seller is negotiating repairs, a lock can run down while the deal might fall apart.
- Waiting until the final week. A lock placed late with a 15-day period leaves no room for an appraisal delay or a missing document. The lock period has to cover the whole remaining path, with a cushion.
A mortgage pre approval without hard pull lets you do the planning first, so you can lock with confidence the day the contract is signed.
Choosing a Lock Period for a PCS or Fixed Report Date
Start from the date you must close, then work backward through the steps that can add days. On a VA purchase, those include confirming your Certificate of Eligibility, ordering the VA appraisal, and meeting the VA’s Minimum Property Requirements. VA.gov explains how to request a COE and the VA home loan process, and those pages are worth checking for current steps because procedures change. If the appraiser flags a property condition, repairs and a re-inspection can add time that a conventional file would not need.
Movers into Quantico, Fort Belvoir, and Dahlgren often face hard report dates and housing deadlines, such as a temporary lodging window ending or a lease expiring. In that situation a 45-day lock can be safer than a 30-day lock even if it prices slightly higher, because the small cost buys margin against delays you don’t control. Your BAH is also set by duty station and published annually, so check the DoD BAH calculator for the current year’s rate at your assigned location before deciding how much payment you can carry.
Some purchases need more than 45 days from the start:
- New construction where the builder’s completion date is an estimate, not a promise.
- Condos where the project approval or association documents take time to arrive.
- Properties with repair conditions that must be completed before closing.
For these, ask about a 60-day or longer lock, or about float-down options, understanding that availability and cost vary by investor.
This is where a broker helps. A single bank offers one lock matrix. With 500+ wholesale sources, Duane Buziak can compare how 30, 45, and 60-day locks are priced across sources and choose the one that fits your timeline, rather than the one a single shop happens to offer.
Worked Example: What a Lock Extension Costs vs. a Rate Jump
The following is an illustration, not a current quote. Suppose a Stafford County VA buyer has a $450,000 loan and locks at a hypothetical 6.50% on a 30-year fixed. Principal and interest only, the payment is about $2,844 a month.
Now suppose the closing slips, the lock expires, and the market has moved so that the same loan reprices at a hypothetical 6.875%. Principal and interest becomes about $2,956.
- Monthly difference: about $112.
- Over 360 payments: about $40,000 in additional interest if the loan is held to term.
Compare that with an extension. Extension terms vary by broker and investor, and some investors may charge a flat amount, a per-day charge, or a fraction of a point. Suppose, hypothetically, a 15-day extension costs 0.125% of the loan amount. On $450,000 that is $562.50. At a $112 monthly difference, that fee equals about five months of the higher payment, and it is a one-time cost that keeps the 6.50% rate for the life of the loan. Do not assume any extension fee is standard. Ask for the actual terms in writing before you need one.
The takeaway is that a modest extension usually costs far less than a rate move, but only when the delay was truly unavoidable. Extending to cover a late appraisal makes sense. Paying repeatedly because documents were not submitted on time is a sign the original lock period was wrong. The cheapest extension is the one you never need, which is why the planning in the previous section matters.
Rates can also fall. If the market improves while you are locked, you generally keep your locked rate unless you have a float-down option or choose to relock, both covered below. A lock trades the chance of a better rate for protection against a worse one.
What Happens If Your Lock Expires or Closing Slips
When closing slips past the lock date, you generally have three options:
- Pay an extension fee. You keep the locked pricing for additional days. The broker and investor set the terms, and you decide whether to pay.
- Relock at the current market rate. This may be better or worse than your original rate. The market sets it, and some investors apply restrictions after an expired lock.
- Close early. If the delay is on your side of the table, you may be able to speed the file up, but title, the appraisal, and the seller’s schedule often control this.
Common causes of delay include appraisal backlogs, title issues, missing paystubs or updated LES documents for military borrowers, and a new credit inquiry or new debt that changes your approval. That last one is entirely in your hands. Do not open accounts or finance a car or furniture between contract and closing without talking to your broker first.
Some investors offer a float-down, which lets you capture a lower rate if the market improves after you lock, usually for a fee. Availability, trigger conditions, and cost vary, so it is something to ask about at the time of locking rather than after.
Disclosure rules help you track all this. Under the TILA-RESPA Integrated Disclosure rule, your Loan Estimate and Closing Disclosure must show whether the rate is locked and when the lock expires. The CFPB’s TRID guidance describes these requirements. Read the lock date on each document and compare it against your scheduled closing.
Rate Lock Comparison: Broker Independence vs. a Single Shelf
How a lock is handled depends heavily on who is behind it. The table compares structure, not specific companies’ claims. “Typical single-source retail shop” describes the general model of a bank or lender-direct office with one set of products and one lock matrix.
| Feature | Duane Buziak (independent broker) | Typical single-source retail shop |
|---|---|---|
| Pricing sources | 500+ wholesale sources compared per file | One company’s pricing |
| Lock-period options | Compared across sources for 30, 45, 60 days and longer where offered | One lock matrix, set by that company |
| Extension and relock handling | Terms depend on the investor selected, and are explained before you lock | Set by one company’s policy |
| Float-down availability | Offered by some investors, so can be selected on purpose | Available only if that company offers it |
| Soft-pull pre-approval | NoTouch Credit Pull, no hard inquiry to start | Varies, so ask before applying |
| VA purchase options down to 500 FICO | Available through select sources, subject to guidelines and investor overlays | Often limited by one company’s overlays |
| After-hours availability | 24/7 contact for time-sensitive locks | Typically business hours |
If you are also talking to Movement, UHM, Frye Lending, Atlantic Coast, or Lendit, ask each of them the same questions from this table and compare the written answers. Make no assumptions about what any of them offer.
A broker is paid on the loan, and that compensation must be disclosed. The CFPB’s loan originator compensation rule sets the framework. Ask to see how compensation appears on your Loan Estimate, and compare total cost, not just the rate.
Eight Rate Lock Questions Fredericksburg Buyers Ask
How long should my lock be for a PCS move?
Most PCS buyers should consider a 45-day lock, because report dates are fixed and VA appraisal or condition delays can add days. The right length depends on your settlement date plus a cushion, so confirm it against your contract.
Can I lock a rate before I have orders or a contract?
No. A lock requires a specific property, and most investors want a ratified contract. You can get a pre-approval and payment estimate before orders or a contract, but the rate stays floating until there is an address.
What happens if my rate lock expires?
You can pay an extension fee, relock at the current market rate, or close sooner. Which is best depends on how far the market has moved and how many days you need.
Can I get a float-down on my lock?
Sometimes. Some investors offer float-downs, typically for a fee, and many do not. Ask before you lock, because it is not usually added afterward.
Does a VA loan lock work differently?
The lock mechanics are the same, but the VA timeline can be longer. COE verification, the VA appraisal, and property requirement repairs can add days, so build them into the lock period. See the VA funding fee and closing costs page for how fees are handled.
Can I start without a hard credit inquiry?
Yes. Duane Buziak uses NoTouch Credit Pull for a no hard inquiry mortgage pre-approval, so you see numbers first. A hard pull comes later when you move forward to a full application.
How much does a lock extension cost?
It varies by broker and investor, and some charge a flat fee, a per-day charge, or a portion of a point. Extension fees are not standard, so get the terms in writing before locking.
Can I relock if rates drop after I lock?
Possibly, but not always. Many investors do not allow a relock to a lower rate during an active lock, or they restrict it. A float-down option is the planned way to capture a drop.
A Lock Protects the Price, Not the Calendar
Choose the lock period from your real closing date plus a cushion for the appraisal, VA conditions, and title. A lock that is too short turns a delay into a repricing, and one that is far too long can cost more than you need to pay. If your settlement or report date is fixed, ask for the lock options in writing before you commit.
