Rate Lock Definition

A mortgage rate lock is a lender's commitment to honor a specific interest rate and related loan terms for a set period, typically ranging from 30 to 60 days. This agreement protects borrowers from rate increases during the mortgage application and approval process.

How Rate Locks Work

📋

Lock Agreement

You and your lender agree to a specific interest rate, points, and fees. This agreement is documented in writing and includes the lock expiration date.

Lock Period

The rate is guaranteed for a specified timeframe, typically 30, 45, or 60 days. Longer lock periods may have additional costs.

🛡️

Rate Protection

If market rates rise during your lock period, your rate remains unchanged. You're protected from upward market movements.

Closing Requirements

Your loan must close before the lock expires to secure the locked rate. Extensions may be available but often come with fees.

What Gets Locked?

A rate lock typically includes several key mortgage components:

Locked Elements

  • Interest Rate: The percentage rate on your loan

Common Rate Lock Questions

When should I lock my rate?

Most borrowers lock their rate when they have a signed purchase agreement and are confident their loan will close within the lock period. In Arizona's competitive market, early rate locks can provide peace of mind.

Does locking a rate cost money?

Standard 30-45 day rate locks typically have no upfront fee. Longer lock periods (60+ days) or special float-down provisions may have additional costs, usually 0.125% to 0.25% of the loan amount per extension period.

Can I unlock my rate if rates drop?

Standard rate locks do not allow unlocking. However, some lenders offer float-down provisions that let you capture lower rates if they drop significantly before closing. Ask about this option when locking.

What happens if my lock expires?

If your lock expires before closing, you'll typically need to extend the lock (often at a cost) or accept the current market rate. It's crucial to close on time or request extensions early.

Rate Locks in Arizona's Market

Arizona's real estate market presents unique considerations for rate lock timing. The state's strong population growth and housing demand in metro areas like Phoenix, Scottsdale, and Tucson means competitive buying situations where early rate locks provide certainty.

With Arizona's typical closing timeline of 30-45 days, standard lock periods align well with most purchase transactions. New construction buyers in growing areas like Chandler and Gilbert may need longer lock periods or multiple extensions.
