KNOWLE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Brentwood local authority area over time, sourced from the HPI. The two KNOWLE sales from April 2007 and July 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 April 2007 sale was for 68% above the HPI. So the extrapolation line tracks at 68% above the HPI over time, until the July 2009 sale, where it rises to 314% above the HPI. The line then continues to track at 314% above the HPI.

What might KNOWLE be worth now?

KNOWLE might now be worth an estimated £3,897,345.

This is based on house price inflation of 94.9%, between July 2009 and December 2024, for detached houses, in the Brentwood local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 94.9% inflationary increase is applied to the most recent sale price for KNOWLE of £2,000,000 on 10th July 2009. For the value to have increased from £2,000,000 to £3,897,345 over the fourteen years and seven months to December 2024, the following assumptions must hold true:

• The value of KNOWLE has moved in line with the HPI for detached houses in the Brentwood local authority area.
• The July 2009 sale price of £2,000,000 represented a fair market value for the property.
• The size, condition, and specification of KNOWLE has not materially changed since July 2009.
