Get started10 Overstone Road is a four-bedroom semi-detached house in Sywell, Northampton, Northampton (NN6 0AW). It has a recorded floor area of 141 m² (around 1518 sq ft), construction records dating it to 1930-1949 and council tax band C. The latest certificate (January 2022) shows a D (score 67), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 80). Records show the property has been extended at some point in its history. The home occupies a cul-de-sac position.
It hasn't traded since May 1997, a hold of 29 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £465,000 sits 520% above the 1997 sale of £75,000. On a £-per-square-foot basis, the last sale (£49/sq ft) was about 72.9% below the postcode norm. 2 planning records sit against the property, 2 approved, 0 refused. Past consents include an extension and a conservatory, meaningful when judging how the property has evolved.
