Today's modelled estimate of £176,000 is 19.6% below the 2022 sale of £219,000, an unusual pattern given regional price growth and worth checking against the EPC condition.

At 36 m² it sits well below the postcode median (92 m² across 13 EPCs), making it one of the more compact homes locally. Most recent transfer: November 2022 at £219,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend. One historical planning record sits against the property in 2005.
