What is a Mortgage Rate Lock?

A mortgage rate lock is a crucial tool in the home buying process.

A mortgage rate lock is an agreement between a lender and a borrower that guarantees a specific interest rate for a set period, often ranging from 15, 30, 45, or 60 days. However, longer options could be available depending on the lender. The rate lock ensures that the interest rate won't change during the agreed-upon timeframe.

Locking in a mortgage rate can allow homebuyers to lock in their rate on a home loan so they don’t risk rates rising between the time they apply and when they close.

Keep reading to learn what a mortgage rate lock is, why mortgage rates change, when homebuyers should consider locking in a rate, and best practices to guide your clients through this crucial aspect of mortgages and financing.

Why Mortgage Rates Change 

Understanding why mortgage rates change is fundamental to guiding clients effectively. Mortgage rates are influenced by a few factors, including: 

Economic Fluctuations: 

Rates can shift based on economic indicators such as inflation, employment numbers, and GDP growth. A strong economy can lead to higher interest rates as a measure to control inflation. 

Changes to the Federal Funds Rate: 

The Federal Reserve's decisions on interest rates have a significant impact on mortgage rates. When the Fed raises its benchmark interest rate, it can lead to higher mortgage rates. 

Supply and Demand: 

Mortgage rates are determined by market conditions, which are influenced by the fundamental laws of supply and demand. When there is a high demand for mortgages, rates tend to go up. On the other hand, when there is a surplus of available funds for lending, rates typically go down. 

When Should Homebuyers Lock in a Rate? 

Homebuyers may want to consider locking in a mortgage rate when they are concerned about potential fluctuations in interest rates before their closing date or general rising interest rates impacting their purchase. Here are some scenarios to illustrate the impact of rate locks: 

Rate Lock Before a Rise: 

If a homebuyer locks in a rate of 4% when rates are stable. If rates rise to 5% before closing, the locked rate of 4% still applies, resulting in lower monthly payments and the potential for significant long-term savings. 

Rate Lock Before a Fall: 

If a buyer locks in a rate at 4% and rates fall to 3.5% before closing, they’re still bound to the higher locked rate. While they miss out on lower monthly payments, they have the peace of mind of a fixed rate in a rising rate environment. 

Trying to forecast rates may be risky and often futile. Instead, homebuyers should consider choosing a time to lock in their rate based on their budget, the forecasted monthly payments, and risk tolerance. 

Keep in mind, interest rates can change even though they’re locked. 

Reasons Your Interest Rate Could Change Even Though It’s Locked

Mortgage interest rate locks provide a sense of stability for borrowers, but several factors can lead to rate changes even when a lock is in place. Some common reasons include: 

Incomplete Documentation: 

Delays caused by incomplete or missing documentation can jeopardize a rate lock. Lenders require specific paperwork, and any delays in providing it can impact the lock's validity. 

Loan Details Alterations: 

Changes in the loan's structure, such as adjustments to the loan amount or type, can necessitate a rate revision. This is especially likely if it affects the loan's risk profile. 

Property Appraisal Variances: 

A significantly different appraisal value than anticipated can trigger rate adjustments. Lenders assess loan-to-value ratios based on appraised values, which may impact the interest rate. 

Credit Score Changes: 

If the borrower's credit score experiences a material shift during the lock period, it can lead to a reevaluation of the locked rate, as creditworthiness is a critical factor in rate determination. 

Best Practices to Guide Homebuyers Through a Rate Lock 

Let's explore some best practices for real estate professionals to assist homebuyers in navigating the rate lock process effectively: 

Educate Homebuyers About Rate Locks 

One primary responsibility for real estate professionals is to educate homebuyers about rate locks. Explain the concept and advantages of rate locks, and highlight the potential risks associated with not locking in a rate. 

Make sure to express that there may be costs associated with rate locks, as some lenders charge fees for rate locks. Encourage clients to clarify these costs upfront with their lender. 

Be Aware of Interest Rate Trends 

Stay informed about interest rate trends by monitoring economic news and the Federal Reserve's actions. Provide insights into where rates might be heading, allowing your clients to make well-informed decisions about when to lock in a rate. 

Refer to reliable sources like National Association of REALTORS® (NAR) Economists' Outlook for up-to-date analysis from experts. This can help you and your clients stay informed about changing interest rates. 

Collaborate with Lenders 

Building strong relationships with lenders can be invaluable for your clients. Lenders can offer insights into the current rate environment, provide competitive rate options, and help guide your clients through the rate lock process. 

Offer Guidance on the Timing of Rate Locks 

While predicting rate movements is impossible, real estate professionals can offer valuable guidance on the pros and cons of mortgage rate locks. 

Help your clients understand the importance of rate stability and how it may align with their financial goals and risk tolerance. By offering sound advice, you can empower your clients to make informed decisions regarding their mortgage rate lock.
