15 WEST STREET 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 two 15 WEST STREET sales from April 2005 and October 2023 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 2005 sale was for 18% below the HPI. So the extrapolation line tracks at 18% below the HPI over time, until the October 2023 sale, where it rises to 15% above the HPI. The line then continues to track at 15% above the HPI.

What might 15 WEST STREET be worth now?

15 WEST STREET might now be worth an estimated £378,722.

This is based on house price inflation of 3.1%, between October 2023 and December 2024, 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 3.1% inflationary increase is applied to the most recent sale price for 15 WEST STREET of £367,500 on 30th October 2023. For the value to have increased from £367,500 to £378,722 over the ten months to December 2024, the following assumptions must hold true:
