22 BLACKWELLHAMS 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 22 BLACKWELLHAMS sales from November 2004 and January 2010 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 November 2004 sale was for 22% below the HPI. So the extrapolation line tracks at 22% below the HPI over time, until the January 2010 sale, which was also at 22% below the HPI.

What might 22 BLACKWELLHAMS be worth now?

22 BLACKWELLHAMS might now be worth an estimated £404,313.

This is based on house price inflation of 63%, between January 2010 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 63% inflationary increase is applied to the most recent sale price for 22 BLACKWELLHAMS of £248,000 on 29th January 2010. For the value to have increased from £248,000 to £404,313 over the thirteen years and one month to December 2024, the following assumptions must hold true:

• The value of 22 BLACKWELLHAMS has moved in line with the HPI for detached houses in the Wiltshire local authority area.
• The January 2010 sale price of £248,000 represented a fair market value for the property.
• The size, condition, and specification of 22 BLACKWELLHAMS has not materially changed since January 2010.
