12 WYVERN 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 three 12 WYVERN AVENUE sales between July 2000 and December 2017 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 March 2006 sale was for 23% below the HPI. So the extrapolation line tracks at 23% below the HPI over time, until the December 2017 sale, where it rises to roughly the same level as the HPI. The line then continues to track in line with the HPI.

What might 12 WYVERN AVENUE be worth now?

This is based on house price inflation of 22.3%, between December 2017 and July 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 22.3% inflationary increase is applied to the most recent sale price for 12 WYVERN AVENUE of £263,000 on 15th December 2017. For the value to have increased from £263,000 to £321,606 over the eight years and five months to July 2025, the following assumptions must hold true:
