21A WINDMILL ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the South Oxfordshire local authority area over time, sourced from the HPI. The two 21A WINDMILL ROAD sales from January 2007 and September 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 January 2007 sale was for 28% below the HPI. So the extrapolation line tracks at 28% below the HPI over time, until the September 2010 sale, which was also at 28% below the HPI.

What might 21A WINDMILL ROAD be worth now?

This is based on house price inflation of 69.6%, between September 2010 and December 2024, for detached houses, in the South Oxfordshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 69.6% inflationary increase is applied to the most recent sale price for 21A WINDMILL ROAD of £335,000 on 9th September 2010. For the value to have increased from £335,000 to £568,011 over the thirteen years and nine months to December 2024, the following assumptions must hold true:

• The value of 21A WINDMILL ROAD has moved in line with the HPI for detached houses in the South Oxfordshire local authority area.
• The September 2010 sale price of £335,000 represented a fair market value for the property.
