21 SPANBOURN AVENUE 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 21 SPANBOURN AVENUE sales from October 2013 and December 2024 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 October 2013 sale was for 8% below the HPI. So the extrapolation line tracks at 8% below the HPI over time, until the December 2024 sale, where it rises to 53% above the HPI. The line then continues to track at 53% above the HPI.

What might 21 SPANBOURN AVENUE be worth now?

This is based on house price inflation of 0.5%, between December 2024 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 0.5% inflationary increase is applied to the most recent sale price for 21 SPANBOURN AVENUE of £499,950 on 6th December 2024. For the value to have increased from £499,950 to £502,488 over the one year and ten months to February 2025, the following assumptions must hold true:
