Today's modelled estimate of £129,000 is 11% below the 2014 sale of £145,000, below the original sale price, which typically signals condition or completion-status changes worth verifying. On a £-per-square-foot basis, the last sale (£396/sq ft) was about 246.1% above the typical sold price in the postcode. At 34 m² it sits well below the postcode median (74 m² across 42 EPCs), making it one of the more compact homes locally. Last sold in December 2014, so it's been off the market for around 11 years.
