Rental Yield vs Buy-to-Let Yield: What's the Difference?
Rental yield is the annual return on a buy-to-let property expressed as a percentage of its purchase price. There are two versions you need to understand: gross yield and net yield. Getting the distinction right is critical — many landlords overestimate their returns by forgetting costs.
Gross Yield vs Net Yield
Gross yield = (Annual Rent ÷ Property Value) × 100. Simple but incomplete.
Net yield = ((Annual Rent − Annual Costs) ÷ Property Value) × 100. Annual costs include mortgage interest, letting agent fees (typically 8–15% of rent), landlord insurance, maintenance (budget 1% of property value per year), ground rent/service charges for leasehold, and void periods.
Example: A property worth £200,000 renting for £1,000/month. Gross yield = 6%. After agent fees (£1,200), insurance (£300), maintenance (£2,000) and one month void period (£1,000): Net yield = (£12,000 − £4,500) ÷ £200,000 × 100 = 3.75%.

Stamp Duty Surcharge on Buy-to-Let Properties
Since October 2024, buy-to-let and second home purchases attract an additional 5% stamp duty surcharge on top of standard rates. On a £200,000 BTL property this adds £10,000 to your acquisition cost — significantly affecting your overall return on investment, especially in lower-yield markets. Always factor SDLT into your yield calculations.
