• The average loan size for a purchase application hit a record $467,300.
• Refinance applications dropped 5% week-over-week.

Rates Surge, Dampening Market Activity

Mortgage rates climbed higher last week, reaching their highest point in a month and prompting a noticeable retreat from the market by both existing homeowners and prospective buyers. The ongoing conflict in the Middle East is cited as a significant factor pushing borrowing costs upward. This surge in rates has created a challenging environment, particularly for those looking to enter the housing market for the first time. Total mortgage application volume saw a decline of 4.4% compared to the previous week, according to data from the Mortgage Bankers Association. This downturn signals a cooling demand as affordability becomes a more significant hurdle for many. Mortgage rates continued their upward trajectory into the current week, with further shifts expected following the release of the government's monthly employment report on Friday.

Purchase Applications Stagnate, Loan Sizes Swell

Applications to purchase a home fell 4% during the week, and the year-over-year increase stands at a modest 5%. This sluggish demand follows a volatile spring housing market, which began slowly due to sharp rate increases in March. While a recent dip in rates and increased supply had offered some hope, buyers are once again grappling with affordability. Compounding the issue of reduced demand is a record-breaking increase in the average loan size for purchase applications. This figure reached $467,300, the highest since the survey began in 1990. This trend suggests that lower-income borrowers and those seeking less expensive homes are being priced out of the market. Joel Kan, vice president and deputy chief economist at the MBA, noted that this increase in average loan size could indicate that first-time buyers and those looking for lower-priced homes are hesitant to proceed amidst economic uncertainty and elevated rates.

Refinancing Activity Plummets to Multi-Month Low

The market for refinancing existing home loans experienced a sharper decline, with applications falling 5% for the week. While demand remains 29% higher than a year ago, this annual comparison has been steadily shrinking. The refinance share of total mortgage activity also decreased, falling to 42% of all applications. This marks the lowest proportion seen since August 2025, underscoring the reduced incentive for homeowners to refinance at current rates. Separately, the average refinance rate for a 30-year fixed-rate home loan was reported at 6.63% as of May 5, according to data from Zillow. This figure is part of a broader trend where rates have remained stubbornly elevated, often hovering near the 7% mark for extended periods.

Historical Context: The 'Lock-In' Effect

The current elevated rate environment stands in stark contrast to the pandemic era, when mortgage rates dipped into the 2% and 3% ranges. This period saw a significant number of homeowners secure low-cost financing. Data from Redfin indicated that as of the third quarter of 2024, a substantial 82.8% of homeowners with mortgages held an interest rate below 6%. This has led to a phenomenon described as a 'lock-in' effect, where many Americans feel disinclined or unable to move or refinance due to the significant increase in borrowing costs. There was a brief period of relief leading up to the Federal Reserve's meetings in September and October of 2024, when rates trended downward. The central bank implemented three quarter-percentage-point cuts to the federal funds rate between September and December of that year. However, rates began to tick upward again in March 2026, following geopolitical events and a subsequent spike in gas prices.

Economic Factors and Future Outlook

The Federal Reserve's decision to cut the federal funds rate in late 2024 did not translate into lower mortgage interest rates as some observers had anticipated. Instead, rates remained elevated, creating a persistent affordability challenge for the housing market. The recent increase in mortgage rates, with the average contract rate for 30-year fixed-rate mortgages rising to 6.45% from 6.37%, is attributed in part to external geopolitical tensions. The average rate for conforming loans, capped at $832,750, also saw an increase in points, reflecting higher origination fees. Looking ahead, the market's direction may be significantly influenced by upcoming economic data, particularly the monthly employment report. This release is expected to provide further clues about the Federal Reserve's potential future actions and their impact on mortgage rates.

The bottom line

• Mortgage rates have risen, with the average 30-year fixed rate reaching 6.45%, impacting buyer affordability.
• Overall mortgage application volume has decreased, indicating a slowdown in housing market activity.
• The average loan size for home purchases has reached a record high, suggesting lower-income buyers are withdrawing from the market.
• Refinancing activity has declined significantly, reaching its lowest share of mortgage applications since August 2025.
• A large majority of existing homeowners hold mortgage rates below 6%, contributing to a reluctance to move or refinance.
• Geopolitical events and economic uncertainty are cited as key drivers of current rate increases.
