Today's modelled estimate of £325,000 is 54.5% below the 2022 sale of £715,000, an unusual pattern given regional price growth and worth checking against the EPC condition.

At 86 m² it's 28.4% larger than the typical home in the postcode (67 m² median across 23 EPCs). On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Sold August 2022 for £715,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
