77 HARDINGS Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The two 77 HARDINGS sales from June 2002 and October 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 2002 sale was for 37% above the HPI. So the extrapolation line tracks at 37% above the HPI over time, until the October 2024 sale, where it falls to 16% above the HPI. The line then continues to track at 16% above the HPI.

What might 77 HARDINGS be worth now?

This is based on house price deflation of 0.2%, between October 2024 and July 2025, for semi-detached houses, in the Welwyn Hatfield local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 0.2% deflationary decrease is applied to the most recent sale price for 77 HARDINGS of £590,000 on 28th October 2024. For the value to have decreased from £590,000 to £588,927 over the one year and three months to July 2025, the following assumptions must hold true:
