9 BLACKTHORN MEWS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Wiltshire local authority area over time, sourced from the HPI. The three 9 BLACKTHORN MEWS sales between June 2002 and November 2018 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 July 2011 sale was for 28% below the HPI. So the extrapolation line tracks at 28% below the HPI over time, until the November 2018 sale, where it rises to 4% below the HPI. The line then continues to track at 4% below the HPI.

What might 9 BLACKTHORN MEWS be worth now?

This is based on house price inflation of 18.5%, between November 2018 and December 2024, for 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 18.5% inflationary increase is applied to the most recent sale price for 9 BLACKTHORN MEWS of £422,500 on 19th November 2018. For the value to have increased from £422,500 to £500,529 over the five years and eleven months to December 2024, the following assumptions must hold true:
