WASHINGTON, DC — Mortgage borrowing costs are climbing again, and the latest jump is a sharp one. Freddie Mac said the average 30-year fixed mortgage rate rose to 7.28% this week, up from 7.03% a week earlier. That is the biggest weekly increase in nearly four years and the sixth straight week of gains.
The average is now at its highest level since November 2023. For households trying to buy a home, that means higher monthly payments than many were facing just a few months ago. At the same time, some rate-sensitive buyers are stepping back, which can reduce competition in parts of the market.
Bond market worries are pushing mortgage rates higher
The recent rise is tied to turmoil in the bond market. The 10-year Treasury yield has moved higher in recent months as investors worry that the Iran war and increased government spending could keep inflation elevated.
Those same concerns can also make investors expect the Federal Reserve to keep interest rates higher for longer. When Treasury yields rise, mortgage rates often follow. That is why home loans can become more expensive even when a buyer’s personal finances have not changed.
For buyers, the result is straightforward: a loan taken out now is likely to cost more each month than one locked in earlier this year. For sellers, weaker demand from rate-sensitive shoppers may make it harder to find a buyer quickly in some markets.
A shorter loan term can lower the rate but raise the payment
Many buyers default to a 30-year fixed mortgage because it spreads payments out and keeps them predictable. But a 15-year mortgage usually comes with a lower interest rate. The trade-off is a much larger monthly bill.
That can make the shorter loan useful for borrowers who can handle the higher payment and want to pay the home off faster. It can be less practical for families that need more room in the budget for other expenses. The lower rate does not automatically mean the lower-cost choice overall if the monthly obligation stretches finances too far.
In other words, the best rate is not always the best fit. The monthly payment has to work alongside insurance, property taxes and everyday household costs.
Adjustable mortgages are drawing more attention despite added risk
Another route to a lower starting rate is an adjustable-rate mortgage, or ARM. As of last week’s Mortgage Bankers Association data, ARM loans accounted for 10.3% of applications, the highest share since October 2025. Those loans were running about 80 basis points below fixed-rate loans.
ARMs can make sense for some buyers because they begin with a fixed period, often five, seven or 10 years, before the rate resets with the market. Jeremy Luke, a divisional director at Chase Home Lending, said that setup may work for borrowers who expect to move or refinance within four or five years.
But ARMs are also riskier than fixed loans. If rates are higher when the fixed period ends, monthly payments can jump sharply. That same feature helped fuel housing risk before the 2008 financial crisis, which is why borrowers need to understand the reset risk before choosing one.
Assumable loans and buydowns can reduce costs if buyers have cash
Some buyers may also be able to take over an existing mortgage through an assumable loan. That option is not available for every home, but many government-backed loans can be assumed, including FHA, VA and USDA loans.
Assumptions can take longer to close, and they often require more cash up front. Because the buyer only takes over the seller’s remaining balance, the difference between that balance and the purchase price usually has to be covered another way. That can make the option appealing on paper but challenging in practice.
Another path is to pay for a buydown. A permanent buydown lowers the rate for the life of the loan, while a temporary buydown trims the rate only for the first few years.
Sellers, builders and banks may help cover part of the rate
Buyers do not always have to absorb the full cost themselves. Sometimes a home seller or a builder will pay for a rate buydown. That has become more common in new construction, where builders are using incentives to bring buyers through the door.
The National Association of Home Builders said 66% of builders reported using sales incentives in September, up from 63% in August and the highest share since December. Those incentives can include mortgage rate buydowns and closing-cost credits.
Some banks and credit unions also offer relationship pricing or special promotions. Chase, for example, sometimes runs “rate sales” for home buyers and refinancing customers, and it may offer a discounted rate to customers who move eligible deposits and investments into the bank.
Shopping with at least three lenders can reveal the real cost
Mortgage experts say rate shopping still matters even when market rates are climbing. Jeff DerGurahian, head economist at loanDepot, said a borrower’s final rate depends on more than the broader market. Credit score, debt-to-income ratio and down payment all affect the quote a lender gives.
That is why applying with at least three lenders is often recommended. Borrowers should compare not just the rate but also closing costs and other fees so they can see the full price of the loan. The lowest rate is not always the cheapest mortgage once all charges are counted.
Borrowers who want to compare offers without hurting their credit can usually do so in a short window. Bankrate says multiple mortgage inquiries can be grouped if the search is kept within 14 to 45 days, reducing the chance of damage to a credit score.
