409 THE SPA Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Wiltshire local authority area over time, sourced from the HPI. The five 409 THE SPA sales between May 2002 and December 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 November 2013 sale was for 154% above the HPI. So the extrapolation line tracks at 154% above the HPI over time, until the December 2015 sale, where it rises to 165% above the HPI. The line then continues to track at 165% above the HPI.

What might 409 THE SPA be worth now?

409 THE SPA might now be worth an estimated £872,298.

This is based on house price inflation of 40.7%, between December 2015 and February 2025, for semi-detached houses, in the Wiltshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 40.7% inflationary increase is applied to the most recent sale price for 409 THE SPA of £620,000 on 18th December 2015. For the value to have increased from £620,000 to £872,298 over the ten years and ten months to February 2025, the following assumptions must hold true:

• The value of 409 THE SPA has moved in line with the HPI for semi-detached houses in the Wiltshire local authority area.
• The December 2015 sale price of £620,000 represented a fair market value for the property.
• The size, condition, and specification of 409 THE SPA has not materially changed since December 2015.
