Should You Lock or Float Your Mortgage Rate?

Written by

in

Locking a rate can protect you if rates rise before closing. Floating can help if rates fall, but it also leaves you exposed to increases.

Reasons to lock

You are close to closing, the payment already fits your budget, or a higher rate would make the loan uncomfortable.

Reasons someone might float

You have time before closing, can handle some movement, and your lender explains the risks clearly.

Questions to ask your lender

Ask about lock length, extension fees, float-down options, points, deadlines, and what happens if your closing date changes.

Mortgage Rate Surfer can show the trend, but your lender should explain your actual lock options, deadlines, and costs.
