What is a Mortgage Rate Lock?

A mortgage rate lock secures your interest rate for a set period, providing stability in your mortgage experience. Since mortgage rates change often, locking in your rate can protect you from potential increases.

Locking in your mortgage rate at the right time can save you a significant amount of money. For example, the national average APR for a 30-year fixed-rate mortgage increased from 6.45% in March 2024 to 7.10% in April 2024. If you secured a $240,000 loan in March, your monthly payment would be $1,509, with a total interest of $303,269 over the loan's lifetime.

However, if you didn't lock in your rate and closed your loan in April, your monthly payment would rise to $1,613, and your total interest paid would increase to $340,633. Currently, the average APR for a 30-year fixed-rate mortgage in May 2024 is 6.72%, which might be a good time to lock in your mortgage rate.

WHY MORTGAGE RATE FLUCTUATE

Understanding why mortgage rates fluctuate can help you better time your mortgage decisions. Economic factors such as inflation, unemployment and economic growth directly impact mortgage rates. In a strong economy, mortgage rates tend to rise due to higher borrowing costs associated with economic growth.

Federal Reserve policy also plays a crucial role. When the Fed raises or lowers the federal funds rate, mortgage rates often follow suit. Additionally, bond market movements influence mortgage rates, as rates tend to move in tandem with U.S. Treasury bond yields.

Finally, supply and demand in the housing market and individual credit scores can affect rates, with higher demand and lower credit risks typically resulting in lower mortgage rates.

Should You Lock in Your Mortgage Rate?

A mortgage rate lock is an option — you don’t need to get one if you don’t think it’ll benefit your situation. It’s best to consider the following points to determine whether securing a mortgage rate lock is in your best interest.

Pros and Cons of a Mortgage Rate Lock

blueCheck icon
Pros
  • Protection Against Rate Increases. A mortgage rate lock provides security against unexpected hikes in interest rates, which could save you a significant amount in the long run.
  • Budgeting Certainty. Knowing your interest rate upfront can help you establish a solid budget, providing a clear idea of your future mortgage payments.
  • Rate Fluctuation Insulation. With a rate lock, you are shielded from the day-to-day volatility of mortgage rates, creating a stable environment for your home buying process.
  • Peace of Mind. Eliminating the worry about rising interest rates can offer mental and emotional relief, making the home buying experience less stressful.
  • Secure Planning. Having a guaranteed rate can simplify the financial planning aspects of home buying, allowing for better focus on other important aspects of the process.

Cons
  • Missed Rate Drops. Once your rate is locked, you won't benefit from any potential rate reductions that may occur.
  • Rate Lock Expiration. If your closing process gets delayed beyond the lock period, you could risk losing your secured rate, possibly incurring additional fees to extend the lock.
  • Non-Transferable Locks. If you decide to switch lenders, your rate lock typically can't be transferred, meaning you'll have to negotiate a new rate.
  • Loan Term Modifications. If you need to change your loan's terms, it might result in losing the locked rate.
  • Rate Lock Fees. Some lenders may charge a fee for the rate lock service, especially for extended rate locks.

Take the time to reflect on your financial circumstances, the current market trends and your long-term goals before deciding whether a rate lock is right for you.

How Long Can You Lock in a Mortgage Rate?

While 30-day and 60-day locks are common, some lenders offer longer options, which might be beneficial, especially for construction loans. You should choose a lock-in period that comfortably covers your loan closing timeline, and if needed, ask your lender about extending the lock — just be aware that there may be a fee for this extension. Paying for a longer lock can sometimes be worthwhile to avoid rising interest rates.

If your rate lock expires before closing and you don't extend it, you'll need to pay the current mortgage rate at closing, which could be higher or lower than your locked rate.

When Is the Best Time to Lock in a Mortgage Rate

A mortgage rate lock can provide stability by securing your interest rate, but it's not always the best option. For instance, if rates are predicted to fall, locking in might cost you potential savings.

Understanding when to lock in your mortgage rate is important, as the timing can significantly impact your overall borrowing costs. Let’s explore some scenarios when securing a mortgage rate lock can bring the most benefit.

How to Lock in a Mortgage Rate

When you’ve weighed your options and determined when you'd like to secure a mortgage rate lock, follow these steps to move forward with the process:

  1. 1
    Assess Your Financial Situation

    Make sure you have a solid grasp of your current financial situation before starting the process. That includes knowing your credit score, budget and down payment size.

  2. 2
    Consider Various Lenders

    Don't settle with your first lender — take time to explore multiple lending institutions. Different lenders can offer different rates and lock-in terms. Some may offer a lower rate but charge higher fees for it.

  3. 3
    Negotiate Terms

    Once you've chosen a lender, discuss the terms of the mortgage rate lock, including the interest rate, mortgage points and the length of the lock period. Remember, a longer lock period can be more expensive.

  4. 4
    Gather Required Documents

    When you’ve worked out the details, provide your lender with the necessary documents to process the rate lock. These usually include proof of income, your credit report and details of the property you intend to purchase.

  5. 5
    Review Your Lock Agreement

    Your lender will provide a lock agreement, which shows the interest rate, points and how long the rate is locked for. Ensure you understand all the terms before signing.

  6. 6
    Monitor Progress

    Keep track of your loan's progress to ensure it stays within the lock period. Delays can happen, and you might need to extend the lock period, which may translate to additional fees.

  7. 7
    Close Before Expiry

    Be sure to close the deal before your lock period expires, otherwise you might be subjected to current market rates, which could be higher.

Can Your Mortgage Rate Still Change?

Even with a mortgage rate lock, your rate might still change in very specific situations. These exceptions are rare but essential to know. Understanding them can help you better prepare for any unexpected changes. Let’s explore these:

    Change in Loan Type or Down Payment

    If you initially applied for a conventional loan but later decide to switch to an FHA loan or increase your down payment amount, the terms and risk profile will change, prompting a reassessment and potential adjustment of your locked mortgage rate.

    Unexpected Appraisal Value

    Suppose the home you wish to buy is appraised significantly lower than anticipated. In that case, the loan-to-value ratio increases, making the loan riskier for the lender and possibly leading to a higher mortgage rate despite the lock.

    badCredit icon

    Credit Score Changes

    If you applied for a new credit card or missed a payment on an existing loan after securing a mortgage rate lock, your credit score might drop. This decline signals a higher risk to the lender, which could result in an adjusted rate.

    coins2 icon

    Undocumented Income

    Imagine your lender initially considered your bonus income to qualify for the loan, but later, they cannot verify it. Without this documentation, your risk profile increases, potentially causing your lender to adjust your previously locked mortgage rate.
