Rents rise at slowest pace for four years – is buy-to-let still worth it?

Slowing rental growth and higher property taxes are creating a headache for landlords. Does buy-to-let still offer a good yield?

Rents are rising at the slowest pace in four years as tenant demand cools and affordability pressures start to bite. It is another blow for landlords, who have seen their profits eroded by tax hikes and more stringent regulations in recent years.

Average UK rents increased by 2.8% in the 12 months to April, according to the latest rental market report from property listing site Zoopla. It brings the average monthly payment to £1,287.

The rate of rental growth is less than half the 6.4% recorded last year. It also lags behind inflation, which came in at 3.5% in April.

“The slowdown is a result of weaker demand and ongoing affordability pressures, rather than an increase in rental supply,” said Richard Donnell, executive director of research at Zoopla.

Demand for rented homes is 16% lower than last year, but remains 60% above pre-pandemic levels.

Zoopla said lower levels of migration for work and study have contributed to the slowdown, having previously spiked in 2022/2023. Stability in mortgage rates and improved access to finance for first-time buyers have also played a role.

Rents may also be hitting an affordability ceiling, having soared after the pandemic when demand massively outstripped supply.

Higher property taxes

Investment properties used to offer attractive yields, but returns have been squeezed in recent years by higher taxes and more stringent regulation.

For example, landlords used to be able to deduct their mortgage interest payments from rental income when calculating their taxable income. This meant they enjoyed tax relief on this portion of the income, paid at their marginal rate.

Changes phased in between 2017 and 2020 replaced this system with a 20% tax credit – less generous for higher and additional-rate taxpayers.

Changes to stamp duty have also resulted in higher costs. Those purchasing a second home now face a 5% stamp duty surcharge following last year’s Autumn Budget, up from 3% previously.

The Renters’ Rights Bill, which is currently progressing through the House of Lords, will also introduce more stringent regulations, including banning no-fault evictions and restricting rent increases to once a year.

The aim is to protect tenants from unscrupulous landlords, but some argue that the new legislation will make it more difficult to get rid of tenants for legitimate reasons too.

Some landlords are selling up and quitting the sector as a result, resulting in a reduction in rental supply.

Is buy-to-let still worth it?

Although annual rental growth slowed to 2.8% in April, Zoopla expects it to pick up to 3-4% over 2025. Some areas are seeing faster growth than others. Belfast saw the biggest annual change in rents in April, up 11.5%. Rents in Leeds fell by 1.5%.

These yields look relatively attractive, despite recent pressures on landlords, but it is important to weigh up whether you will be able to match these average levels once all costs are taken into consideration.

This could include mortgage costs, maintenance costs, letting agent fees, landlord insurance and more. If you have void periods between tenants where no rent is coming in, you will be operating at a loss too.

If you are managing the property yourself, you will also need to decide whether the hassle is worth it. For context, some multi-year fixed-rate savings accounts are currently yielding around 4.5% with a lot less effort and risk.

Cash doesn’t offer the prospect of capital appreciation in the same way as a property, of course, which could go up in value if house prices rise.
