15 WINDMILL HEIGHTS Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Basildon local authority area over time, sourced from the HPI. The three 15 WINDMILL HEIGHTS sales between May 2001 and August 2013 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 2002 sale was for 21% above the HPI. So the extrapolation line tracks at 21% above the HPI over time, until the August 2013 sale, where it falls to 8% above the HPI. The line then continues to track at 8% above the HPI.

What might 15 WINDMILL HEIGHTS be worth now?

15 WINDMILL HEIGHTS might now be worth an estimated £450,379.

This is based on house price inflation of 90.8%, between August 2013 and February 2025, for semi-detached houses, in the Basildon local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 90.8% inflationary increase is applied to the most recent sale price for 15 WINDMILL HEIGHTS of £236,000 on 9th August 2013. For the value to have increased from £236,000 to £450,379 over the twelve years and six months to February 2025, the following assumptions must hold true:

• The value of 15 WINDMILL HEIGHTS has moved in line with the HPI for semi-detached houses in the Basildon local authority area.
• The August 2013 sale price of £236,000 represented a fair market value for the property.
