Today's modelled estimate of £600,000 is 20.5% below the 2017 sale of £755,000, below the original sale price, which typically signals condition or completion-status changes worth verifying. On a £-per-square-foot basis, the last sale (£1,754/sq ft) was about 35.1% below the postcode norm. At 40 m² it sits well below the postcode median (121 m² across 31 EPCs), making it one of the more compact homes locally. Last sold in May 2017, so it's been off the market for around 9 years.
