Mortgage demand has weakened significantly in the second quarter of 2026, primarily due to high borrowing costs and ongoing affordability pressures. This trend is important for landlords and investors in buy-to-let mortgages, as it indicates a cooling market that could impact rental yields and property values.
What is the current state of mortgage applications?
According to the latest Mortgage Market Index from Stonebridge, mortgage applications have dropped by 18.5% year-on-year between April and June 2026. Remortgage applications saw a significant decline of 20.8%, while purchase applications fell by 15.5%. First-time buyer applications also decreased by 15.7%, indicating a broader trend of reduced demand across various segments of the market.
How are borrowing costs impacting the market?
The average mortgage rate reached 4.97% in Q2 2026, an increase from 4.31% in Q1 2026 and 4.74% in Q1 2025. This rise in borrowing costs is a significant factor contributing to the decline in mortgage applications. With higher rates, potential buyers may be deterred from entering the market, while existing homeowners may reconsider remortgaging options.
What does this mean for buy-to-let landlords?
For landlords, the decline in mortgage demand could lead to a slowdown in property purchases, potentially stabilising or even reducing property prices. As affordability pressures mount, landlords may find it challenging to pass on increased costs to tenants, which could impact rental yields. The average loan amount across all mortgages fell by 1.8% to £209,932, but first-time buyers borrowed an average of £216,984, up 1.5% from a year earlier. This suggests that while first-time buyers are still active, overall market activity is subdued.
What should landlords and investors watch next?
Landlords and investors should monitor ongoing trends in mortgage rates and applications closely. The Bank of England’s data indicates that mortgage approvals in May were 10.8% lower than a year earlier, which could signal a continued decline in market activity. Additionally, the share of borrowers opting for two-year fixed-rate deals has increased to 70%, while five-year fixes have decreased. This shift may indicate a strategy among borrowers to manage short-term costs amidst uncertainty.
