• Flexible letting can consistently deliver higher returns compared to traditional long-term letting by reducing vacancy periods and maximising earning potential during peak seasons.
• Dynamic pricing, tenant vetting, lower vacancy rates, and complete compliance are crucial to protecting your rental property’s ROI in 2026.

ROI for Rental Property: Maximising Yields in London

Investing in real estate, specifically rental properties, can lead to a substantial profit for the owner. But how can you make sure you’re getting the right return on your investment?

Return on Investment (ROI) for a rental property measures the profit it generates relative to its cost, expressed as a percentage.

Understanding how to calculate and maximise the ROI for rental property is key to effective property management operations. It will tell you whether you need to push further to increase your rental income and reach your investment goals.

How to calculate ROI for rental property

Calculating the ROI of a rental property follows a simple formula.

ROI = (Annual Net Rental Income / Property Cost) x 100

• Annual Net Rental Income is the total rental income minus property operating costs. These expenses are management, compliance, utilities, and vacancy costs.
• Property Cost is the total purchase price and all costs incurred in connection with it, including stamp duty, refurbishment, setup costs, and furnishings.

For example, if a £250,000 property earns £24,000 in annual rent and incurs an expense of £6,000, the net rental income is £18,000. The ROI computation will be as follows:

ROI = (£18,000 / £250,000) x 100

ROI = 7.2%

A 7.2% ROI would generally be considered a healthy return for a London rental property. The ideal ROI depends on factors such as property location, property type, financing costs, and investment strategy. Many investors prioritise stable long-term growth alongside annual rental returns.

Across City Relay’s managed London portfolio, some properties improve their annual rental performance by using flexible letting. This involves switching between short-, mid-, and long-term letting based on seasonal demand rather than relying on a single letting model year-round. We observed that this letting approach reduces void periods while capturing stronger rates during peak demand.

The London Private Rented Sector in 2026

London landlords expressed their concern when the Renters’ Rights Act was passed. On top of that, the higher taxes announced in the Autumn Budget made them question whether the London PRS is still worth it.

Despite higher compliance costs and evolving regulations, London continues to offer strong rental opportunities for landlords who actively manage pricing, occupancy, and operational efficiency.

Did you know:

As of September 2025, the average gross rental yield in the UK is 5.8%, while it’s 5.1% in London. – Zoopla

London’s average gross rental yield appears to be lower than the UK average because property values are significantly higher. However, stronger year-round demand, premium nightly rates in the short-let market, and higher capital appreciation potential make it one of the UK’s most attractive long-term rental markets.

So, while regulatory and tax obligations increase the complexity of property management, profitability remains high. London landlords just have to use smarter letting strategies to stay ahead.

When calculating ROI, landlords should also account for rising ownership costs, such as higher taxes, financing expenses, compliance upgrades, maintenance and utilities, and insurance premiums. Knowing how these costs affect annual net income allows you to calculate a more realistic ROI projection than relying solely on rental income.

Tips to Maximise ROI for Rental Property Management

Maximising ROI is not just about raising rental rates or filling booking calendars. It’s about optimisation.

Here are strategies you can use to maximise ROI for your rental property this 2026.

Dynamic pricing strategies

Fixed rental fees limit your property’s revenue potential. Dynamic pricing works best when rates are reviewed daily or in response to booking activity, major London events, school holidays, and local demand. This helps properties stay competitive during quieter periods while capturing premium rates during the peak summer season.

For instance, a traditional long-let for a two-bedroom apartment we manage in Soho at £5,000 a month can, if maximised, produce a gross annual income of £60,000. 

By switching to our flexible hybrid strategy, we can secure premium nightly rates of £399 during peak tourism season, with the potential to generate £35,000+ in just 90 days. Once the property reaches London’s 90-night short-let planning limit, we seamlessly transition the property to a mid-let strategy. Earning £6,000 per month for the remaining 6 to 9 months could mean an additional £36,000 to £54,000, bringing your total gross annual income between £71,000 and £89,000, assuming strong occupancy throughout the year.

At City Relay, pricing is reviewed daily based on market demand, local events, competitor rates, booking pace, seasonality, and occupancy forecasts, rather than relying on fixed monthly pricing.

Effective tenant and guest vetting

Having quality tenants and guests reduces property damage, maintenance and repair costs, and rent arrears and disputes. All these can affect your property’s net income and ROI.

A thorough screening and vetting process will help. This includes:

• Credit and background checks to ensure financial stability and assess rental history.
• Income verification, especially for tenants, to ensure they can afford rent and won’t skip payments.
• Reference previous landlords to check reliability and behaviour.

None of these will guarantee a perfect tenant or guest, but they will give you some idea about their character.

Lower vacancy rates

Occupied rental properties increase ROI. Use flexible letting that combines short-, mid-, and long-term lets to avoid weeks of vacancy between bookings. This letting strategy positions your property to accommodate shorter leisure stays during peak tourist seasons and then transitions to longer corporate mid-lets during quieter months.

Minimal operating costs

Increasing the ROI of your rental property also means reducing operating costs. Keep track of all maintenance and assessments and create a regular schedule. This will minimise breakdowns and emergencies (out-of-hours services can be costly!) Take note of repairs and replacements, so you know when the next one is due.

Streamlining operations can also help you keep expenses low, which in turn keeps your profit margin high.

Property management technology

Modern property management platforms combine dynamic pricing, automated guest communication, channel management, occupancy forecasting, compliance tracking, maintenance scheduling, and financial reporting within a single dashboard. This reduces manual administration while improving operational efficiency.

At City Relay, we use Opago, a proprietary smart platform, to track occupancy, booking pace, pricing performance, compliance deadlines, maintenance activity, and revenue.

Complete compliance

The changing landscape of the PRS brings real financial risks of non-compliance, including fines and penalties. It could even compromise your property’s ability to rent.

By complying, you are not just abiding by the laws. You are also meeting local housing standards that keep your property safe for the occupants. This protects your ability to continue generating rental revenue.

This shows how compliance protects ROI by reducing the likelihood of enforcement action, emergency expenditure, void periods, and unexpected downtime.
