12 WEST PARK AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Basildon local authority area over time, sourced from the HPI. The two 12 WEST PARK AVENUE sales from June 1996 and August 2024 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 June 1996 sale was for 31% above the HPI. So the extrapolation line tracks at 31% above the HPI over time, until the August 2024 sale, where it falls to 3% below the HPI. The line then continues to track at 3% below the HPI.

What might 12 WEST PARK AVENUE be worth now?

This is based on house price inflation of 3.2%, between August 2024 and June 2025, for 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 3.2% inflationary increase is applied to the most recent sale price for 12 WEST PARK AVENUE of £630,000 on 7th August 2024. For the value to have increased from £630,000 to £650,348 over the one year and two months to June 2025, the following assumptions must hold true:
