20 NORTHAMPTON GROVE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Basildon local authority area over time, sourced from the HPI. The two 20 NORTHAMPTON GROVE sales from August 1995 and April 1999 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 August 1995 sale was for 31% above the HPI. So the extrapolation line tracks at 31% above the HPI over time, until the April 1999 sale, where it falls to 24% above the HPI. The line then continues to track at 24% above the HPI.

What might 20 NORTHAMPTON GROVE be worth now?

20 NORTHAMPTON GROVE might now be worth an estimated £390,122.

This is based on house price inflation of 491.1%, between April 1999 and June 2025, for terraced 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 491.1% inflationary increase is applied to the most recent sale price for 20 NORTHAMPTON GROVE of £66,000 on 9th April 1999. For the value to have increased from £66,000 to £390,122 over the 25 years and ten months to June 2025, the following assumptions must hold true:
