About 9 King George Avenue
9 King George Avenue is a four-bedroom semi-detached house in Walton On Thames (KT12 3LP). It has a recorded floor area of 137 m² (around 1475 sq ft), construction records dating it to 1900-1929 and council tax band E. The latest certificate (November 2015) shows a D (score 68), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 84), a 2-band jump. The latest certificate is from November 2015, so improvements made since then won't be reflected.
At 137 m² the property is well over the postcode median (95 m² across 21 EPCs), placing it in the larger end of the local stock. Across 2009–2016, sale prices on this property compounded at 15.3% per year. Today's modelled estimate of £798,000 is 22.8% above the 2016 sale price.
