Can Rates Change After Approval? What Borrowers Face

You found your dream home, signed the purchase agreement, and received a loan approval from your lender. The rate on your approval paperwork looks attractive, and you have already budgeted around that monthly payment. Then a week before closing, your loan officer calls with unsettling news: the rate has moved. Is that allowed? Can rates change after approval, or are you protected by the paperwork you signed?

The short answer is yes, your interest rate can change after approval in many cases, but the details depend on the type of rate lock you have, the fine print in your loan estimate, and how quickly you act. Understanding the rules around rate locks, float-down options, and lender policies can mean the difference between closing at your expected payment or facing a surprise increase. This guide breaks down exactly when and why rates can shift after approval, what protections exist, and how you can minimize your risk as a borrower.

Understanding the Difference Between Approval and Rate Lock

Mortgage approval and a rate lock are two separate milestones in the home buying process, and confusing them is a common source of frustration. Loan approval means the lender has reviewed your credit, income, and assets, and has agreed to lend you a certain amount under specific terms. A rate lock, on the other hand, is a guarantee from the lender that your interest rate and points will not change for a set period, typically 30, 45, or 60 days.

When you receive a loan approval, the rate quoted on your Loan Estimate is often an estimate, not a locked rate. The lender may have based it on current market conditions, but until you formally lock the rate in writing, it can fluctuate with the bond market. Many borrowers assume that approval equals a locked rate, which leads to confusion when the final closing disclosure shows a different number.

To protect yourself, always ask your loan officer directly: “Is this rate locked? If so, what is the lock expiration date?” A legitimate lender will provide this information in writing. If the rate is not yet locked, ask about the process and timing for locking, and whether there is a fee involved. For a deeper look at how rate locks operate in practice, our guide on rate change protections for buyers explains the common scenarios in detail.

When Can Rates Change After Approval? Key Scenarios

Even with a rate lock in place, there are situations where your rate can still change. Understanding these exceptions helps you stay prepared and avoid unpleasant surprises at the closing table.

1. Your Financial Profile Changes

Your approval is based on the information you provided during the application process. If your credit score drops, you take on new debt, or you change jobs before closing, the lender may need to re-evaluate your loan file. A lower credit score or higher debt-to-income ratio can push you into a higher risk category, which may result in a higher interest rate. This is why financial advisors recommend avoiding major purchases, new credit cards, or job changes during the mortgage process.

2. The Property Details Change

The home itself also affects your rate. If the appraisal comes in lower than expected, if the property type changes (for example, from a single-family home to a condo), or if the down payment amount shifts, the lender may adjust your pricing. A lower loan-to-value ratio typically improves your rate, while a higher one can increase it. Changes to the purchase price or loan amount can also trigger a repricing.

3. You Choose a Different Loan Program

Switching from a fixed-rate to an adjustable-rate mortgage, or from a conventional loan to an FHA loan, will naturally change your rate. Even selecting a different loan term, such as moving from a 30-year to a 15-year mortgage, alters the pricing. Always confirm that the loan program on your final disclosure matches the one you originally discussed.

4. Market Conditions and Lock Expiration

If your rate lock expires before closing, the lender is no longer obligated to honor the original rate. Market rates may have risen during your lock period, and the new rate could be higher. Rate lock extensions can often be purchased, but they come with a cost, usually in the form of a higher rate or an extension fee. This is why it is essential to choose a lock period that comfortably covers your expected closing date.

Rate Lock Types: What Protects You and What Does Not

Not all rate locks are created equal. The type of lock you choose directly impacts whether your rate can change after approval. Here are the most common options you will encounter.

• Standard Rate Lock: This locks your rate for a specific period, usually 30 to 60 days. If you close within that window, your rate is guaranteed, barring changes to your application or the property.
• Float-Down Option: This allows you to take a lower rate if market rates drop during your lock period. It typically costs extra upfront, but it gives you the benefit of falling rates without losing your locked rate.
• Floating Rate: With this option, your rate is not locked at all. It moves with the market until you decide to lock. This can work in your favor if rates are falling, but it carries significant risk if they rise.

Before choosing a rate lock, ask your lender to explain each option and its associated costs. A reputable lender will walk you through the trade-offs based on your timeline and market conditions. For example, if you are closing in 45 days, a 60-day lock may give you peace of mind, even if the rate is slightly higher than a 30-day lock. The small additional cost is often worth the security.

Remember that a rate lock protects you from market fluctuations, but it does not protect you from changes in your own financial situation. Maintain your credit score, avoid new debt, and keep your down payment funds stable to ensure your lock holds. If you are unsure about the best lock strategy for your situation, consider using a mortgage calculator to model different rate scenarios and see how they affect your monthly payment.

What the Loan Estimate and Closing Disclosure Reveal

The Loan Estimate (LE) and Closing Disclosure (CD) are two critical documents that show whether your rate has changed. The LE is provided within three business days of your application, and it outlines your estimated rate, monthly payment, and closing costs. The CD is provided at least three business days before closing, and it contains the final terms of your loan.

When comparing these documents, pay close attention to the interest rate, the annual percentage rate (APR), and the total loan costs. If the rate on the CD is higher than the rate on the LE, ask your lender for a written explanation. Under the Truth in Lending Act, certain changes can trigger a new three-day review period, which could delay your closing. If you believe the rate change is unjustified, you have the right to question it and request a revised CD.

In some cases, rate changes are due to legitimate factors, such as an appraisal issue or a change in your credit score. In other cases, they may be the result of a lender error or an expired rate lock. Understanding the rules around these documents gives you leverage to negotiate or walk away if necessary. For a step-by-step review of the approval process and how to spot these changes early, our home buyer guide to rate changes offers practical examples.

How to Protect Yourself From Unexpected Rate Increases

While you cannot control market forces, you can take steps to minimize the risk of a rate change after approval. Here is a practical checklist to follow from application to closing.

1. Lock your rate as soon as you are confident in your closing date. Waiting to lock can save you money if rates fall, but it exposes you to increases. If you are risk-averse, lock early.
2. Read every document carefully. Do not skim the Loan Estimate or Closing Disclosure. Verify that the rate, loan amount, and terms match what you agreed to.
3. Keep your financial profile stable. Avoid new credit inquiries, large deposits, or job changes until after closing. Any of these can trigger a repricing.
4. Ask about a float-down option. If you are worried about rates dropping after you lock, this add-on lets you benefit from lower rates without losing your lock.
5. Stay in close contact with your lender. A proactive loan officer will alert you to any potential issues before they become problems. If you have questions, ask them immediately.

Following this checklist can save you from the stress of a last-minute rate hike. But even with the best preparation, you may still face a situation where your rate changes. In that case, you have options. You can negotiate with your lender, request a different loan product, or walk away from the deal if the new terms are unacceptable.

What to Do If Your Rate Changes After Approval

If you receive a new disclosure with a higher rate, do not panic. Start by asking your lender to explain the reason for the change in writing. Legitimate reasons include an expired lock, a change in your credit profile, or a property-related issue. If the explanation is vague, request a detailed breakdown of the pricing adjustments.

Next, evaluate whether the new rate is still competitive. Compare it to current market rates using a reliable rate comparison tool. If the new rate is significantly higher than what other lenders are offering, you may have grounds to push back. You can also ask if the lender offers a rate lock extension at a reduced cost, or if you can switch to a different loan program that offers a lower rate.

In some cases, you may choose to walk away from the loan altogether. This is a serious decision, as it could mean losing your earnest money deposit or delaying your home purchase. Weigh the costs of a higher monthly payment against the costs of starting over with a new lender. If you are close to closing, a small rate increase may be less expensive than extending your contract or paying additional fees.

Finally, remember that you have the right to shop around. Even if you have been approved by one lender, you are not obligated to close with them. A competing lender may offer a better rate, and you can use that as leverage to negotiate with your current lender. The key is to act quickly, as rate quotes are time-sensitive.

When Rate Changes Work in Your Favor

It is not all bad news. Rates can also change downward after approval, especially if you have not yet locked. If market rates drop, you can request a lower rate before locking. Even with a locked rate, a float-down option allows you to take advantage of favorable shifts.

To benefit from falling rates, monitor mortgage rate trends throughout your approval process. Financial news websites and rate tracking tools provide daily updates. If you see rates drop significantly, contact your lender immediately to discuss your options. Timing is critical, as rates can move quickly.

Another scenario where a rate change works in your favor is when your financial profile improves. For example, if you pay down a large credit card balance or add a co-borrower with a strong credit score, you may qualify for a better rate. Be sure to inform your lender of any positive changes, as they may not automatically re-evaluate your file.

Final Thoughts on Rate Changes After Approval

Navigating the mortgage process requires vigilance, especially when it comes to your interest rate. The question “can rates change after approval?” does not have a simple yes or no answer. It depends on your rate lock, your financial stability, the property details, and the lender’s policies. By understanding the mechanics of rate locks, reading your disclosures carefully, and maintaining open communication with your lender, you can reduce the likelihood of an unwelcome surprise.

Remember that knowledge is your best defense. If a rate change does occur, you have the power to question it, negotiate, or seek a better deal elsewhere. The mortgage market is complex, but with the right preparation, you can secure a rate that fits your budget and move forward with confidence. And if you are ever in doubt, consult a trusted mortgage professional or use a reliable rate comparison platform to guide your decisions. Learn more
