US Mortgage Rates Fluctuate as Housing Demand Slows Down

Average US 30-year fixed mortgage rates showed mixed movements through August 25, 2026, reaching 6.63% on Zillow's marketplace while weekly survey data from the Mortgage Bankers Association showed contract rates holding around 6.77%.

Fluctuating borrowing costs and persistent affordability constraints have dampened consumer interest in the housing sector. Mortgage application volume fell by 0.4% week-over-week, according to data from the Mortgage Bankers Association.

Refinance applications posted a 2% weekly increase despite remaining 18% lower than the same period last year. Meanwhile, home purchase applications dropped 2% over the week and recorded a 3% decline from 2025 levels.

Economic uncertainty and high rates continue to weigh on prospective buyers. Joel Kan, vice president and deputy chief economist at the Mortgage Bankers Association, commented on the trend.

"Mortgage rates and applications changed little last week, with just a slight increase in refinances for conventional and VA loans, while FHA refinances were lower," said Joel Kan, MBA vice president and deputy chief economist. "Borrowers with larger loan sizes remain less likely to refinance with rates at these higher levels. The average loan size on refinances continues to shrink, dipping to $282,200 last week, the lowest level since June 2025."

Higher borrowing costs have also influenced consumer decision-making in the new residential market. Kan explained how these financial pressures affect buyers.

"In addition to the economic uncertainty, affordability difficulties have reemerged as a reason for homebuyers to delay purchase decisions given the impact of higher mortgage rates on monthly mortgage payments," said Joel Kan, MBA vice president and deputy chief economist.

The impact extended to newly constructed residences, where mortgage applications fell 5.7% year-over-year in July 2026 and dipped 1% compared to June, based on the MBA's Builder Application Survey.

The annualized pace of new single-family home sales dropped to 647,000 units in July, down 3% from June's rate of 667,000 units. Conventional loans comprised 50% of July's new home loan applications, followed by FHA loans at 34.6%, VA loans at 13.6%, and USDA loans at 1.8%.

Market demand remains soft as elevated inventory levels interact with higher interest rates. Kan detailed the factors influencing the new home market slowdown.

"Purchase activity for newly built homes slowed in July, with both applications to purchase and the estimated number of new home sales falling behind last year’s pace," said Joel Kan, MBA vice president and deputy chief economist.

Long-term housing forecasts suggest interest rates will maintain current levels through the end of the year. The Mortgage Bankers Association expects 30-year fixed rates to average between 6.60% and 6.70% throughout 2026 and 2027, while Fannie Mae projects rates between 6.70% and 6.80% over the same period.
