Executive Summary
The Finance Act 2025 introduces a key policy change by extending mortgage interest tax relief to include loans for constructing residential homes. Taxpayers can now claim annual deductions of up to KES 360,000 on interest paid for building, purchasing or improving owner-occupied properties. While the reform aims to promote homeownership and stimulate the housing sector, limitations such as the relatively low deduction cap and rising construction costs pose challenges. This report analyzes the impacts, identifies key findings, and provides recommendations for enhancing the policy’s effectiveness.
Introduction and Background
Kenya continues to experience low homeownership rates, with 72.3% of urban households renting (KNBS 2023/24 Housing Survey). Escalating land prices, mortgage rates averaging 12.5% (2025), and an average construction cost increase of 12.03% have further strained aspiring homeowners. The Finance Act 2025 responds to these challenges by broadening the scope of mortgage interest deductions to include loans for constructing residential properties, aiming to make homeownership more attainable and drive investment in real estate.
