Why is stamp duty at additional dwelling rates?

Most property flips are second properties, subject to the 3% SDLT surcharge. If this is your only property, remove the additional 3% from the estimate. Always consult a solicitor for accurate SDLT figures.

What should I budget for renovation costs?

Light cosmetic refurbishment typically costs £15–30k. A full structural renovation can reach £50–100k or more. Always add a 15–20% contingency for unexpected works.

What agent fee should I use?

Estate agent fees for selling typically range from 1–3% of the sale price (plus VAT). Online-only agents charge a flat fee but require more input from you. The default 1.5% is a reasonable UK average.
