Rental yield versus cash flow: what UK investors should check
Gross yield can help screen a property, but it is not a complete investment analysis. The Toolkit asks buyers to connect realistic rent, recurring costs, financing and the capital committed before drawing conclusions.
Toolkit source pages: Rental income & cash flow, page 6; worked example, page 15.
Start with achievable rent, not the best advert
Use evidenced achievable rent rather than the highest advertised figure you can find. Record the evidence and identify what is assumed. The difference between an advertised asking rent and an achievable letting matters when you are relying on income to meet ongoing costs.
Allow for the costs of operating the property
Consider void periods where appropriate. Include service charge, applicable ground rent, insurance, maintenance, management and other recurring costs. Gross annual rent does not represent money available to spend. Keep operating performance separate from financing costs so you can understand each layer of the analysis.
Examine financing separately
Interest-rate assumptions, mortgage structure, arrangement costs and refinancing assumptions can affect resilience. Do not assume today’s financing conditions will always be available. The relevant figures depend on the property and your circumstances; the guide does not recommend a mortgage or borrowing level.
Questions to ask
- What evidence supports the rent?
- Which recurring costs have written support?
- Have I allowed for a period without rent?
- Is cash flow still tolerable with lower income or higher costs?
Use the example as a method, not a forecast
The PDF contains a deliberately simplified London-flat example. Its purpose is to show relationships between rent, operating costs, finance and capital—not to predict returns or label a property as a good investment. Apply that same discipline to your own evidence and compare base and downside cases.
