WARREN HOUSE 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 WARREN HOUSE sales from January 1997 and November 2000 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 1997 sale was for 55% above the HPI. So the extrapolation line tracks at 55% above the HPI over time, until the November 2000 sale, where it rises to 103% above the HPI. The line then continues to track at 103% above the HPI.

What might WARREN HOUSE be worth now?

WARREN HOUSE might now be worth an estimated £1,337,136.

This is based on house price inflation of 276.7%, between November 2000 and February 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 276.7% inflationary increase is applied to the most recent sale price for WARREN HOUSE of £355,000 on 9th November 2000. For the value to have increased from £355,000 to £1,337,136 over the 25 years and nine months to February 2025, the following assumptions must hold true:

• The value of WARREN HOUSE has moved in line with the HPI for detached houses in the Basildon local authority area.
• The November 2000 sale price of £355,000 represented a fair market value for the property.
• The size, condition, and specification of WARREN HOUSE has not materially changed since November 2000.
