21 BYTHEBROOK 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 21 BYTHEBROOK sales between December 1995 and December 2009 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 June 2007 sale was for 25% below the HPI. So the extrapolation line tracks at 25% below the HPI over time, until the December 2009 sale, where it rises to 19% below the HPI. The line then continues to track at 19% below the HPI.

What might 21 BYTHEBROOK be worth now?

21 BYTHEBROOK might now be worth an estimated £421,199.

This is based on house price inflation of 68.5%, between December 2009 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 68.5% inflationary increase is applied to the most recent sale price for 21 BYTHEBROOK of £250,000 on 18th December 2009. For the value to have increased from £250,000 to £421,199 over the fifteen years to December 2024, the following assumptions must hold true:

• The value of 21 BYTHEBROOK has moved in line with the HPI for detached houses in the Wiltshire local authority area.
• The December 2009 sale price of £250,000 represented a fair market value for the property.
• The size, condition, and specification of 21 BYTHEBROOK has not materially changed since December 2009.
