9 FOSTER CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Stevenage local authority area over time, sourced from the HPI. The two 9 FOSTER CLOSE sales from July 1997 and March 2010 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 July 1997 sale was for 37% above the HPI. So the extrapolation line tracks at 37% above the HPI over time, until the March 2010 sale, where it falls to 28% above the HPI. The line then continues to track at 28% above the HPI.

What might 9 FOSTER CLOSE be worth now?

This is based on house price inflation of 96.8%, between March 2010 and July 2025, for detached houses, in the Stevenage local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 96.8% inflationary increase is applied to the most recent sale price for 9 FOSTER CLOSE of £422,500 on 25th March 2010. For the value to have increased from £422,500 to £831,505 over the fourteen years and eight months to July 2025, the following assumptions must hold true:
