Rate Lock

What Is a Rate Lock?

A rate lock is a lender’s commitment to hold a specific mortgage interest rate for a set period of time during the loan approval process.

It protects borrowers from rising interest rates before closing.

Rate locks are commonly used in home purchases and refinances.

Why a Rate Lock Matters

Mortgage rates can fluctuate daily.

A rate lock:

  • Secures your quoted rate
  • Protects against market increases
  • Provides cost certainty

Rate locks typically last 30 to 60 days, though terms vary.

Mortgage rate practices are influenced by guidelines from entities such as Fannie Mae and Freddie Mac.
