What is the average return on a buy-to-let property?

As of August 2023, the average yearly return on a buy-to-let property is £1,817, down from £6,046 in August 2022. This refers to the amount remaining once mortgage interest payments have been deducted from rental income.

This decrease is due to rising mortgage rates in recent months. When buy-to-let mortgage rates increase, anyone looking to take out a new loan will have much higher monthly interest payments. This puts pressure on rental prices, which are already rising. We compared how buy-to-let returns have changed over time in line with changing house prices, mortgage rates and rent prices.

In August 2023, landlords would have paid approximately £1,110 in buy-to-let mortgage interest. An average monthly rental price of £1,261 leaves them with returns of £151, adding up to £1,817 over the year.

This is a substantial decrease in returns from August 2022, when just £639 in interest was paid, and there was an average rental price of £1,143, giving returns of £504. This adds up to £6,046 over the year.

These estimates show the owner of the average buy-to-let property could earn £4,229 less a year if a 2-year loan was fixed in August 2023 compared to August 2022. This is why there are fears about landlords selling their buy-to-let properties and leaving the rental market as they don’t want to sign up to a new mortgage rate.

Period Interest rate Average monthly returns
August 2018 2.24% £622.34
August 2019 2.13% £659.33
August 2020 1.88% £704.18
August 2021 1.79% £761.64
August 2022 3.52% £503.81
August 2023 6.10% £151.39

How many buy-to-let properties are there in the UK?

In 2022, around 4.61 million people were living in buy-to-let properties. The total number of buy-to-let properties is likely higher, as some rental properties would have been unoccupied.

However, reports suggest more landlords are selling their rental properties, with estimates that 400,000 properties have been sold between 2016 and May 2023 and 126,500 properties have been sold since the beginning of 2022. The same estimates suggest that 1 in 10 rental properties could be lost from the market by the end of 2023.

Rises in the base rate this year have meant that mortgage rates are soaring in the buy-to-let market as well as the residential market, and this makes it less appealing for landlords to invest in property.

What is the average buy-to-let deposit?

A typical deposit for a buy-to-let property is usually 25% of the property price, but this can vary between 20% and 40%. The minimum deposit will usually be higher than a standard residential mortgage deposit.

Buy-to-let mortgages in arrears

There were 8,980 buy-to-let mortgages in arrears of 2.5% or more in the second quarter of 2023, 28% more than in the previous quarter. Within the total, there were 4,810 buy-to-let mortgages in the lightest arrears band, representing between 2.5% and 5% of the outstanding balance.

The highest amount of arrears owed in the past three years was in April-June 2023, as buy-to-let mortgages in arrears made up 0.44% of all outstanding buy-to-let mortgages.

How many buy-to-let properties are repossessed?

In the second quarter of 2023, 440 buy-to-let mortgaged properties were taken into possession, a 7% increase on the previous quarter. In 2022, a total of 1,450 buy-to-let properties were repossessed.

The first quarter of 2020 had the highest number of possessions over the past three years, as 640 properties were possessed. However, this decreased by 80% by the second quarter of 2020, as only 130 buy-to-let properties were possessed.

    To calculate buy to let returns, Finder took the average monthly house prices according to the ONS house price index and interest rates on a 2-year fixed rate 75% LTV buy-to-let mortgage according to the Bank of England. The mortgage interest rates were then calculated using the Money Helper mortgage calculator. The average UK rent prices were taken from Homelet, and the average interest paid on a mortgage was then subtracted from the average rent to get the returns.
