30 OSBORNE 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 30 OSBORNE ROAD sales from December 2007 and March 2021 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 December 2007 sale was for 78% above the HPI. So the extrapolation line tracks at 78% above the HPI over time, until the March 2021 sale, where it falls to 55% above the HPI. The line then continues to track at 55% above the HPI.

What might 30 OSBORNE ROAD be worth now?

This is based on house price inflation of 9.9%, between March 2021 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 9.9% inflationary increase is applied to the most recent sale price for 30 OSBORNE ROAD of £1,325,000 on 17th March 2021. For the value to have increased from £1,325,000 to £1,456,349 over the four years and one month to February 2025, the following assumptions must hold true:
