11 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 two 11 BLACKTHORN MEWS sales from April 1998 and November 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 April 1998 sale was for 27% below the HPI. So the extrapolation line tracks at 27% below the HPI over time, until the November 2015 sale, where it falls to 29% below the HPI. The line then continues to track at 29% below the HPI.

What might 11 BLACKTHORN MEWS be worth now?

This is based on house price inflation of 36.7%, between November 2015 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 36.7% inflationary increase is applied to the most recent sale price for 11 BLACKTHORN MEWS of £271,000 on 13th November 2015. For the value to have increased from £271,000 to £370,567 over the eight years and eleven months to December 2024, the following assumptions must hold true:
