17 CHALGROVE 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 17 CHALGROVE sales from February 2006 and November 2013 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 February 2006 sale was for 28% below the HPI. So the extrapolation line tracks at 28% below the HPI over time, until the November 2013 sale, which was also at 28% below the HPI.

What might 17 CHALGROVE be worth now?

This is based on house price inflation of 61.8%, between November 2013 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 61.8% inflationary increase is applied to the most recent sale price for 17 CHALGROVE of £419,950 on 5th November 2013. For the value to have increased from £419,950 to £679,490 over the twelve years and nine months to February 2025, the following assumptions must hold true:
