How we pick these lots
Our model values each property using comparable Land Registry sold prices, local market trends, and property attributes. We then compare that estimate to the auction guide price. "Best Buy" tier requires a guide ≤ £300,000 and an estimated value ≥ 1.5× the guide. Read more in our buying at auction guide.
