Don’t forget the lock fee!

Locking your rate in could potentially save you money in interest repayments if rates were to go up ahead of your settlement date. That being said, paying for a rate lock may not always be worth your while. Rate locks are typically calculated as a small percentage of the overall loan value – if your home loan is on the larger side, a rate lock could cost you more than it’ll save you.

Consider the interest rate environment

Rate locks are designed to protect the borrower against interest rates going up, but if rates go down after you’ve locked yours in, you’ll have paid money for the privilege of losing more money. With this in mind, you may want to do some research into recent rate movements and do your best to figure out which direction rates might be headed in next. That way, you can make a more informed decision about whether a rate lock is appropriate for you or not.
