3 OSBORNE GARDENS 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 3 OSBORNE GARDENS sales from May 1998 and July 2002 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 May 1998 sale was for 62% above the HPI. So the extrapolation line tracks at 62% above the HPI over time, until the July 2002 sale, where it falls to 36% above the HPI. The line then continues to track at 36% above the HPI.

What might 3 OSBORNE GARDENS be worth now?

This is based on house price inflation of 132.4%, between July 2002 and December 2024, 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 132.4% inflationary increase is applied to the most recent sale price for 3 OSBORNE GARDENS of £530,000 on 19th July 2002. For the value to have increased from £530,000 to £1,231,614 over the 21 years and seven months to December 2024, the following assumptions must hold true:
