The latest data from HMRC reveals that landlord rental income in the UK has plateaued at £59 billion, following a significant rise since 2020. This stagnation could have implications for the mortgage market, particularly for landlords and investors navigating their financial strategies.

What Factors Contributed to the Income Plateau?

Since 2020, total rental income from UK properties increased by 26%, or £12.3 billion, driven by a rise in average property income and an increase in the number of landlords reporting income. However, the latest figures indicate that this growth has now levelled off. The average property income for unincorporated landlords reached £20,500 in 2024-25, marking a 24% increase since 2020-21, but the overall income has not risen further.

How Are Different Regions Affected?

Geographically, 17% of unincorporated landlords are based in London, contributing to 28% of all declared rental income. The combined regions of London and the South East account for a third of total rental income, while the North East represents the smallest share at just 2%. This regional disparity may influence investment decisions and mortgage applications as landlords assess the viability of their properties.

What This Means for the Mortgage Market

The plateau in rental income may prompt landlords to reassess their financial strategies, especially those relying on rental yields for mortgage repayments. With 45% of unincorporated landlords earning £10,000 or less, many may find it challenging to cover rising costs, particularly as expenses related to repairs, maintenance, and finance costs continue to climb. Landlords declared £12.82 billion in residential finance costs in 2024-25, representing 37% of all expenses claimed against property income.

Frequently Asked Questions

What should landlords do in response to the income plateau?

Landlords may need to evaluate their property portfolios and consider diversifying their investments or adjusting rental prices to maintain profitability.

How does this impact mortgage applications?

The plateau in rental income could lead lenders to scrutinise mortgage applications more closely, particularly for those with lower rental yields or higher expenses.
