Analyse property-level profitability across your portfolio. Assumes £250k property value for yield calculations.
Portfolio summary
Simplified analysis. Actual profitability depends on property valuations, void periods, maintenance costs, and your personal tax position.
Reading your portfolio numbers
This tool models the profitability of each property: net profit (rent less mortgage interest and other expenses) and gross and net yield. Yields here use a £250,000 value per property as a baseline; your real yield uses each property's actual value or purchase price.
Net profit before tax is only half the picture. Because of Section 24, most individual landlords are taxed on rent before deducting mortgage interest, so your after-tax return can be materially lower than the net profit shown here, especially for higher-rate taxpayers with large mortgages. Use the Section 24 calculator alongside this to see the tax impact.
A portfolio view also surfaces the weaker properties (low or negative net yield) that are worth reviewing, whether for refinancing, restructuring, or sale.
