When Should You Lock Your Mortgage Rate? – Mortgage Rate Lock Explained

Posted on June 2, 2023

If you're in the process of buying a home or refinancing your mortgage, you've probably heard about the importance of locking your mortgage rate. 

But when exactly should you do it? It's a common question that borrowers often struggle with. 

In this blog post, we'll dive into the topic and provide you with some insights to help you make an informed decision. 

At Clemens Mortgage Group, we specialize in mortgage brokerage services in Gilbert, Arizona, and we're here to guide you through the process. So let's get started!

Understanding Mortgage Rate Locks

Before we discuss the optimal timing for locking your mortgage rate, let's first understand what a rate lock is. When you lock your mortgage rate, it means that the lender guarantees you a specific interest rate for a certain period of time, typically until your loan closes. This protects you from potential rate increases during that period, giving you peace of mind and stability in knowing what your monthly mortgage payment will be.

Factors to Consider

Now that you know what a rate lock is, let's explore some factors to consider when deciding the right time to lock your mortgage rate.

1. Market Conditions

One crucial factor to consider is the current state of the housing market and interest rates. Mortgage rates can fluctuate daily based on various economic factors, so it's essential to keep an eye on the trends. If rates are low and you're satisfied with the current rate being offered, it might be a good time to lock. However, if rates are volatile or trending downward, you might want to consider waiting and monitoring the market before making a decision.

2. Loan Processing Time

Another factor to take into account is the estimated time it will take to process your loan. Different lenders and loan types may have varying processing times. It's important to work closely with your mortgage broker to get an accurate estimate. If the processing time is expected to be longer than usual, you may want to consider locking your rate for a more extended period to ensure that it remains protected until your loan closes.

3. Your Risk Tolerance

Your personal risk tolerance also plays a role in deciding when to lock your mortgage rate. If you're someone who prefers stability and wants to eliminate the uncertainty of rate fluctuations, locking your rate early in the process might be the right choice for you. 

On the other hand, if you're comfortable with a certain level of risk and believe that rates might improve in the near future, you might choose to float your rate and wait for a potentially better deal. Keep in mind that floating your rate exposes you to the possibility of rates increasing, which could result in a higher monthly payment.

Benefits of Early Rate Locks

Now that we've discussed the factors to consider, let's explore the benefits of locking your mortgage rate early.

1. Rate Protection

Locking your rate early provides you with rate protection. If rates increase after you've locked, your rate will remain the same, ensuring that your monthly mortgage payment stays within your budget. This protection is especially valuable if you're on a tight budget or if your loan processing time is expected to be longer.

2. Peace of Mind

By locking your rate early, you gain peace of mind knowing that your rate won't change. This allows you to focus on other aspects of the homebuying or refinancing process without worrying about potential rate increases. You can plan your finances more effectively and confidently move forward with your homeownership goals.

3. Avoiding Rate Volatility

The mortgage market can be unpredictable, with rates sometimes experiencing significant fluctuations within a short period. By locking your rate early, you can avoid being at the mercy of rate volatility. This is particularly important if you're concerned about affordability or if you've found a rate that aligns with your budget and financial goals. Locking your rate early ensures that you won't be caught off guard by sudden rate increases, allowing you to proceed with confidence.

The Downside of Early Locks

While there are benefits to locking your mortgage rate early, it's essential to understand the potential downsides as well. Here are a few things to consider:

1. Missed Opportunities

If you lock your rate early and interest rates subsequently drop, you may miss out on potential savings. This can be frustrating, especially if rates significantly decline shortly after you've locked. It's important to weigh the potential cost savings of waiting against the risk of rates increasing.

2. Rate Lock Expiration

When you lock your rate, there's typically an expiration date associated with the lock. If your loan doesn't close within that timeframe, you may need to request an extension, which can come with additional costs. It's crucial to work closely with your mortgage broker and stay informed about the progress of your loan to ensure that you don't encounter any complications or unexpected delays.

3. Rate Adjustments

In some cases, lenders may offer options for rate adjustments even after you've locked. These adjustments may allow you to take advantage of lower rates if they become available before your loan closes. However, keep in mind that these options may come with additional fees or conditions. It's important to carefully review and understand the terms before considering a rate adjustment.
