1 SION ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Bath and North East Somerset local authority area over time, sourced from the HPI. The two 1 SION ROAD sales from April 1996 and February 2015 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the April 1996 sale was for 443% above the HPI. So the extrapolation line tracks at 443% above the HPI over time, until the February 2015 sale, where it rises to 446% above the HPI. The line then continues to track at 446% above the HPI.

What might 1 SION ROAD be worth now?

1 SION ROAD might now be worth an estimated £2,416,324.

This is based on house price inflation of 60.3%, between February 2015 and May 2026, for semi-detached houses, in the Bath and North East Somerset local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 60.3% inflationary increase is applied to the most recent sale price for 1 SION ROAD of £1,507,500 on 26th February 2015. For the value to have increased from £1,507,500 to £2,416,324 over the ten years and nine months to May 2026, the following assumptions must hold true:

  • The value of 1 SION ROAD has moved in line with the HPI for semi-detached houses in the Bath and North East Somerset local authority area.
  • The February 2015 sale price of £1,507,500 represented a fair market value for the property.
  • The size, condition, and specification of 1 SION ROAD has not materially changed since February 2015.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
