The Pros and Cons of Mortgage Rate Locks for Homebuyers!

The stock market was making news one day recently because it was surging upwards due to some rumors that the Fed was going to cut interest rates soon. But almost as quickly as that news broke, the Federal Reserve Chair Jerome Powell issued a statement saying that they were not planning on doing so, at least quite yet. And that made the stock market go back down again…

But it is not only Wall Street that keeps an eye on interest rates and makes decisions based upon where they are potentially headed; it is also something many homebuyers do.

Any hint of interest rates falling will always get the attention of people considering buying a house, but especially now with rates being higher than they were a year or two ago, and many buyers hoping they will take a decent dip downward.

But while fixed-rate mortgages are certainly indirectly impacted by what the Fed decides to do, it is the 10-year Treasury yield that more directly impacts what rates are being made available to homebuyers, which causes them to rise or fall ahead of what the Fed actually does, but based upon what people expect them to do.

To put it simply, mortgage rates could (and often do) decrease even before the Fed actually decides to cut the rates.

Then again, they could go up, depending upon who the market feels things are going to pan out in the near future. There is literally no predicting. Which is why a mortgage rate lock can be a good decision, if you are in the market to buy a house.

What Is a Rate Lock?

A mortgage rate lock is an agreement between a borrower and a lender to lock in a specific interest rate on a mortgage loan for a certain amount of time. This locks in the interest rate and prevents them from fluctuating during the lock period, which is typically between 30 and 60 days, although longer lock periods are sometimes available.

The purpose of a rate lock is to protect the borrower from potential increases in interest rates while the loan application is being processed, as mortgage rates can fluctuate daily based on market conditions. Once the rate lock is in place, even if interest rates rise, the borrower is still entitled to the lower rate agreed upon during the lock period.

When Can You Lock In?

There are some exceptions, but rate locks are typically used when a borrower has found a suitable property and wants to secure financing at a specific interest rate before completing the purchase.

However, while most rate locks are only good for 30-60 days once a buyer has a house under contract, according to Bankrate, there are some lenders and programs that will allow you to lock a rate anywhere from 30-120 days, and even before the buyer has actually found a home to purchase.

So, the short answer to when you can lock in is: It depends upon the lender and the programs they offer.

Depending upon your situation and needs, you may have to shop around for a lender who can accommodate the length of time you want to lock a rate. But it is never going to be a situation where you can lock in a sweetheart deal for the next year or two if rates go down. There is a limit to the amount of time they will give you, which typically amounts to a couple of months.

The Pros and Cons of Rate Locks

As with many things in life, there are some pluses and minuses to rate locks. Before deciding if it is the right decision for you and your situation, here are some of the pros and the cons you should consider:


  • It protects against rates going up between now and when you purchase your house.

  • A lower interest rate will not only save you monthly in the short-term, but also a lot more money over the life of the loan.

  • It can make the hectic and often stressful process of buying a home less stressful by eliminating one of the major sources of stress when rates are volatile and potentially going up.

  • It can protect you from losing the house you want to buy if you’re cutting it close in terms of how much you can afford for a monthly payment, and a rise in interest rates would knock you out of being able to afford the house you want.


  • While some lenders will give you a rate lock before finding a house to buy, many will require you to have a specific property lined up.

  • There could be some stress and pressure created due to the amount of time you have to close on the property before the rate lock expires, which could lead to making rash or rushed decisions during the process. For example, you may not be able to be as cool, calm, and collected when negotiating home inspection issues if you’re worried about losing a rate lock.

  • It could lock you out of getting an even lower rate. If interest rates decrease during the lock period, the borrower is typically not able to take advantage of the lower rates unless the lender offers a “float down” option, which allows you to adjust to the lower rate within certain parameters. So make sure this is an option your lender will extend to you if that happens.

  • It will cost you some money. Most of the time you’re going to have to pay a fee to lock the rate. It should make sense given the amount of savings a lower rate will create for you, but make sure to do the math before agreeing to the fees the lender requires, and be fairly certain you are going to be able to close on the property before the rate lock you paid for expires, otherwise it’s wasted money.

  • You are not just locking into the rate, but also the lender. So make sure you are choosing one you trust and feel is giving you the best terms and rate before you lock in a rate with them.

The Takeaway:

Lately it seems as if mortgage interest rates could as easily go up as they could go down at any given moment. So if you are in the process of buying a home, you may want to “lock in” your mortgage rate just in case rates go up before you get to the closing table.

A rate lock can shield you from rates going up, and if you have a “float down” option, it will allow you to get the lower rate if they go down instead of rising. Just make sure to consider the pros and cons of locking your rate before committing to one, because it will come with some limitations and time constraints, and cost some money to secure the lower rate.
