Case Study Reveals True Earnings of £3.4m UK Property Portfolio

A recent case study published by Property118 examines the actual earnings generated by a £3.4 million property portfolio in the UK. The analysis highlights the importance of reviewing not just headline values, but also cashflow, equity, and the impact of changing mortgage rates.

The portfolio in question belonged to a married couple with two children, with other family members or employees involved in the rental business. The portfolio consisted of 20 properties across England, Scotland, and Wales, mostly residential with four commercial properties. Nineteen properties were held personally, and one was owned by a limited company. Rental income and expenditure were managed through a dedicated business bank account, and partnership accounts were being prepared.

Key figures from the case study include a current property value of £3,405,000, gross annual rent of £208,740, and mortgage balances totalling £2,334,000. This resulted in apparent property equity of £1,071,000, a portfolio loan-to-value ratio of 68.5%, and a gross rental yield of 6.13%.

Operating costs, including repairs, management, insurance, compliance, and voids, were estimated at 25% of gross rent, or approximately £52,185 per year. With annual mortgage interest at £73,100, the estimated cashflow before tax was around £83,455 per year. This equated to a cashflow return on equity of approximately 7.8% before tax.

The study also stress-tested the portfolio against a potential rise in mortgage interest rates. If the average mortgage rate increased to 6%, annual mortgage interest would rise to about £140,040. Under these conditions, estimated cashflow before tax would drop significantly to £16,515 per year.

The case study demonstrates that headline portfolio values and gross rents can be misleading without a detailed analysis of costs, equity, and the sensitivity of returns to interest rate changes. Property118 notes that such reviews are particularly relevant for landlords considering incorporation, refinancing, retirement, succession planning, or reducing property exposure.
