The average landlord portfolio is claimed to be generating £88,454 a year in gross rent income, according to analysis by property management firm Rushbrook. This represents an increase of £16,476 from £71,978 a year earlier.
The figures are based on an average of 7.3 properties, with an estimated combined value of £1.7m. Both the number of properties and their estimated value remained unchanged over the year.
Estimated annual rent income per property rose by 22.9%, from £9,860 to £12,117 in the first quarter of 2026. Concurrently, estimated buy-to-let mortgage debt for the average portfolio increased by 14.6%, from £642,000 to £736,000.
Roma Sharma, Rushbrook's managing director, highlighted that while gross rental income has increased, landlords still face various expenses. These include mortgage costs, maintenance, taxation, and compliance, with mortgage borrowing also having risen.
The firm also estimated the cost of professional management for an average portfolio. Using a midpoint of 11.5% for fully managed services, the annual cost is estimated at £12,207, an increase of £2,274 from the previous year.
