21 THE PRIORY 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 21 THE PRIORY sales between December 2005 and March 2014 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 2010 sale was for 56% above the HPI. So the extrapolation line tracks at 56% above the HPI over time, until the March 2014 sale, where it falls to 49% above the HPI. The line then continues to track at 49% above the HPI.

What might 21 THE PRIORY be worth now?

21 THE PRIORY might now be worth an estimated £622,284.

This is based on house price inflation of 83%, between March 2014 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 83% inflationary increase is applied to the most recent sale price for 21 THE PRIORY of £340,000 on 18th March 2014. For the value to have increased from £340,000 to £622,284 over the eleven years and one month to February 2025, the following assumptions must hold true:

• The value of 21 THE PRIORY has moved in line with the HPI for semi-detached houses in the Basildon local authority area.
• The March 2014 sale price of £340,000 represented a fair market value for the property.
• The size, condition, and specification of 21 THE PRIORY has not materially changed since March 2014.
