Locked In by a Low Mortgage Rate? Questions to Ask Before Moving

For years, a low mortgage rate felt like pure good news. Then rates rose, and many owners noticed something different: the rate that made owning affordable can also make moving feel expensive. When a new loan would carry a much higher rate, the question is no longer just "Can we afford a bigger home?" but "What are we giving up to get one?"

Key takeaways

• A household with a mortgage rate well below current rates may face a much larger payment on a new loan, even for a similar-sized home.
• In a hypothetical comparison, a payment of about $1,153 at 2.75 percent becomes about $2,129 for a larger loan at 7 percent, before taxes and insurance.
• Rate is only one part of the cost of moving, since closing costs, moving expenses and property taxes also change.
• Some households respond by changing the home they own instead of moving, and each option carries its own costs and trade-offs.
• Whether a loan can be taken over by a buyer depends on its terms, and a buyer generally has to qualify.

What changes when you move

A mortgage rate stays with the loan, not with the household. Moving to a new home generally means paying off the old loan and taking out a new one at current rates. If the new rate is far above the old one, the monthly payment on the next home can jump, even when the price is only modestly higher.

A worked comparison

Consider a hypothetical household with $250,000 remaining on a mortgage at 2.75 percent, with 25 years left. The monthly principal and interest payment is about $1,153.

Now suppose it sells and buys a $400,000 home with 20 percent down. If the down payment comes from the sale, the new loan is $320,000. At 7 percent over 30 years, the principal and interest payment is about $2,129.

That is roughly $976 more each month, before accounting for property taxes, insurance or any difference in maintenance. Part of the increase comes from the larger loan, but a large share comes from the higher rate.

These numbers are illustrations. Your own balance, rate, equity and local prices will produce different results, and a lender's actual quote will depend on credit, down payment and market conditions.

Costs beyond the rate

The rate is one piece of a larger picture. A move can also involve:

• Closing costs on the purchase, and selling costs on the current home.
• Moving expenses and any temporary housing.
• Changes in property taxes and insurance on the new property.
• A smaller cash cushion after the down payment and moving costs.

Each is worth estimating before comparing, since they affect how long it would take before the move makes financial sense.

Why a household might still move

Cost is only one reason to move. A growing family, a new job, a longer commute, care for a relative, or a simple wish for a different place can each outweigh a higher payment for some households. The aim of running the numbers is not to talk anyone out of those reasons. It is to know the price of acting on them.

Other paths some households consider

Not every housing need requires a new address. Some households add space or renovate the home they have. Others wait, rent for a period, or rethink the location or size of the next home. Each approach has its own costs, risks and timelines, and none is universally better.

Another point sometimes comes up in the other direction. In a loan assumption, a buyer takes over the seller's mortgage and keeps the original terms, according to the Consumer Financial Protection Bureau. The buyer generally has to qualify, much as for a new mortgage, and whether a particular loan allows assumption depends on its terms. It is worth knowing the term exists, though it is not an option for every loan.

Questions to ask before moving

1. What would the full monthly housing cost be on the next home, including taxes and insurance?
2. How much of the increase comes from the price, and how much from the rate?
3. What is driving the move, and how much is it worth to the household?
4. How long do we expect to stay, and what would the extra cost add up to over that time?
5. What cash cushion would remain after closing and moving costs?
6. What would it cost to make the current home work instead?

Answering these doesn't make the decision for anyone. It replaces a general feeling of being stuck with specific numbers, and that makes the next step clearer.

Common questions

Why do some homeowners feel stuck with a low mortgage rate?

Giving up a low rate usually means taking a new loan at today's rates. If those are much higher, the monthly payment on the next home may rise even if the price is similar, which makes moving feel expensive.

Can a buyer take over a seller's mortgage?

In a loan assumption, a buyer takes over the seller's mortgage and keeps the original terms. The Consumer Financial Protection Bureau notes that the buyer generally must qualify, and whether a particular loan allows it depends on its terms.

Are there alternatives to moving?

Some households renovate or add space to the home they own, or wait for a change in circumstances. Each has costs and risks, and what fits depends on the household's needs, budget and local market.
