20 GUESSENS ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The two 20 GUESSENS ROAD sales from August 1996 and March 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 August 1996 sale was for 17% above the HPI. So the extrapolation line tracks at 17% above the HPI over time, until the March 2024 sale, where it rises to 41% above the HPI. The line then continues to track at 41% above the HPI.

This is based on house price inflation of 0.7%, between March 2024 and February 2025, for 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 0.7% inflationary increase is applied to the most recent sale price for 20 GUESSENS ROAD of £1,312,500 on 21st March 2024. For the value to have increased from £1,312,500 to £1,321,216 over the one year and one month to February 2025, the following assumptions must hold true:
