When you apply for a mortgage, one of the first things your lender does is lock your interest rate. That rate lock is a promise that you will get that specific rate for a set amount of time, usually 30 to 60 days. It protects you if market rates go up during your home buying process. But what happens if you decide to switch lenders before closing? Many homeowners assume the rate lock follows them, but it does not. Each lender works independently, and your rate lock only applies to the lender you are working with at the time. If you switch to another lender, you will have to start a brand new rate lock with that company. This can be a big surprise if you are not ready for it.
The first thing to understand is that rate locks are not transferable. If you have a great rate with Lender A and then decide to move to Lender B because they offer a lower fee or faster service, Lender B is not obligated to honor the rate you had with Lender A. They will give you a new rate based on current market conditions on the day you lock with them. If mortgage rates have gone up since you locked with your first lender, you could end up with a higher rate than you expected. On the other hand, if rates have dropped, you might actually get a better deal. The key is to never assume your old rate will carry over.
Another thing to watch out for is the cost of the rate lock itself. Some lenders charge a fee to lock your rate, especially if you want a lock longer than the standard period. If you already paid that fee to your first lender, you will not get it back when you switch. That money is gone. The new lender may also charge its own rate lock fee, meaning you pay twice. That is why it is smart to ask upfront if there is any cost to lock and whether it is refundable if you decide to go elsewhere.
The timing of your switch matters a lot. If you are close to your closing date and switch lenders, the original rate lock will expire before the new lender can process your loan. Most rate locks have a strict expiration date. If you do not close by that date, the lock expires and you are left with a floating rate. That floating rate could be much higher than what you locked. A new lender will need time to review your application, order an appraisal, verify your income, and do all the paperwork. This can take weeks. If your old lock is about to run out, switching could force you into a higher rate or require you to pay for an extension on the old lock just to buy time. Many lenders offer extensions, but they come with a fee, often a fraction of a point or a flat dollar amount.
If you are thinking about switching lenders, you should first check what the old lender will do if you stay. Sometimes they will match a lower rate or reduce fees to keep your business. It never hurts to have a conversation. But if you do decide to leave, ask the new lender if they can match or beat the rate you had. Be upfront about the rate you were offered. Some lenders will work hard to win your business, especially if you are close to closing and the deal is straightforward.
There is also the matter of the appraisal. Your first lender likely ordered an appraisal when you locked your rate. That appraisal is tied to that lender. If you switch, the new lender may not accept the old appraisal. They might require a new one, which costs another several hundred dollars. Some lenders will take a transfer of the appraisal if the first lender cooperates, but that is not guaranteed. You could end up paying for two appraisals, and the second one might come back lower or higher, which could affect your loan terms.
Finally, be aware of the impact on your closing date. Switching lenders almost always delays closing. The new lender has to restart the underwriting process. If you have a strict closing date in your contract with the seller, you could risk missing it. That could lead to penalties or even losing the house. You will need to ask the seller for an extension, which they might not grant if they have other offers.
In short, a rate lock is not a coupon you can take to any lender. It belongs to the specific company you started with. If you switch, you get a fresh lock based on today’s market. That could be good or bad, but it is a risk. Before you jump to a new lender, look at the costs of the switch, the time it will take, and the current rate environment. Sometimes staying put is the safer choice even if the other lender looks cheaper on the surface.
