Frequently Asked Questions
How do I calculate rental yield on a buy-to-let property?▼
Gross rental yield is calculated by dividing the annual rent by the property purchase price, then multiplying by 100. For example, a property costing £200,000 with £1,000/month rent has a gross yield of 6%. Net yield deducts expenses like maintenance, insurance, and management fees.
How much stamp duty do I pay on a buy-to-let property in 2026?▼
Buy-to-let properties in England and Northern Ireland attract an additional 5% stamp duty surcharge on top of standard rates. Use our SDLT calculator to get an accurate breakdown based on your purchase price.
What is a good rental yield for buy-to-let?▼
A gross rental yield of 5-8% is generally considered good for buy-to-let investments in the UK. However, this varies by location - northern cities often offer higher yields while London typically has lower yields but better capital growth potential.
