Mortgage Rate Lock: How to Lock In Your Interest Rate
The most important factor in your mortgage may be the interest rate. Your interest rate will determine your monthly payment and the total lifetime cost of your mortgage. Getting the best rate is crucial to your home buying journey. Understanding when to lock your rate may help save you thousands of dollars over the lifetime of your mortgage.
Daily mortgage rates fluctuate, and as a prospective homebuyer, you may be wondering where that leaves you. What will happen if you wait? When is the right time to lock your rate?
As rates vary, whether you’re a first-time homebuyer, planning on moving into a new home, or looking to refinance an existing mortgage, it’s important to utilize the industry savvy of your loan officer.
What if a lender could guarantee that today’s interest rate will remain available until you close on your new home? We will explain what a mortgage rate lock is, how it protects you, when you should lock your rate, and the options we provide at First Heritage Mortgage.
What is a Mortgage Rate Lock?
A mortgage rate lock is a guarantee from your lender to secure a specific interest rate for a given time period. This ensures you will have that rate when you get to your closing.
Typically, you will only have the option to lock your rate once you have a fully ratified sales contract. This is because your lender can only offer rate locks for a limited amount of time. First Heritage Mortgage’s standard rate lock periods are 35 and 50 days. The loan must close prior to the deadline, or the lock will be forfeited, unless an extension is obtained, which usually carries a fee.
How a Rate Lock Protects You
After you’ve signed your sales contract and obtained a mortgage rate lock, you have protection from any interest rate increases. The only exceptions to this are if changes occur to your application, affecting your eligibility for the loan.
While you have protection from higher rates, you also won’t get a lower rate. Some lenders may provide you with a one-time option to “float down” your rate if market rates decrease, but this illustrates why locking in your rate when the best options are available is imperative.
When Should You Do a Rate Lock?
Once you are approved for a loan with an interest rate and monthly payment you are comfortable with, you should start thinking about locking your rate.
Rates will always go up and down. Focus on the things you can control.
You can:
- Know the mortgage process
- Stay up-to-date on the market trends
- Seek advice from your loan officer
- Complete your prep work
- Ensure accuracy on your application
- Make sure there are no changes to your credit
When Can You Void a Rate Lock?
Rate locks could be voided if your application changes. That could include changes to your income, employment, or credit score. It could also include appraisals that differ from expectations. Revisions to the loan itself, such as the length or type of mortgage, will also trigger a new rate.
That’s why it’s important to control as many of these aspects as you can. Of course, you can’t control everything or prevent unforeseen circumstances, but having a thorough understanding of the mortgage process can help avoid some of these. Your loan officer can also offer their expertise and ensure you’ve got the information you need to make the best decision for your home financing.
How Do I Lock My Mortgage Rate?
With your ratified sales contract in hand and your loan application processed, your loan officer will guide you through the process of finalizing your mortgage rate lock.
Some lenders, like First Heritage Mortgage, also have extended rate lock programs that go beyond the typical 35 and 50-day periods. Our extended rate lock program gives buyers up to 360 days of a guaranteed interest rate.
The longer time frame will allow you to move through your mortgage process or finish your new home construction with ample time and peace of mind.
There’s no need to let the complexities of interest rates or changes in the economy get in the way of finding your new home.
