143 SISH LANE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Stevenage local authority area over time, sourced from the HPI. The four 143 SISH LANE sales between December 1998 and March 2017 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 March 2014 sale was for 57% above the HPI. So the extrapolation line tracks at 57% above the HPI over time, until the March 2017 sale, where it falls to 44% above the HPI. The line then continues to track at 44% above the HPI.

What might 143 SISH LANE be worth now?

This is based on house price inflation of 26.1%, between March 2017 and July 2025, for semi-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 26.1% inflationary increase is applied to the most recent sale price for 143 SISH LANE of £450,000 on 31st March 2017. For the value to have increased from £450,000 to £567,228 over the seven years and eight months to July 2025, the following assumptions must hold true:

• The value of 143 SISH LANE has moved in line with the HPI for semi-detached houses in the Stevenage local authority area.
• The March 2017 sale price of £450,000 represented a fair market value for the property.
