12 GRANGEWOOD 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 four 12 GRANGEWOOD sales between October 1996 and September 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 2016 sale was for 15% below the HPI. So the extrapolation line tracks at 15% below the HPI over time, until the September 2021 sale, where it rises to 11% below the HPI. The line then continues to track at 11% below the HPI.

What might 12 GRANGEWOOD be worth now?

This is based on house price inflation of 5.4%, between September 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 5.4% inflationary increase is applied to the most recent sale price for 12 GRANGEWOOD of £790,000 on 6th September 2021. For the value to have increased from £790,000 to £832,651 over the four years and seven months to February 2025, the following assumptions must hold true:

• The value of 12 GRANGEWOOD has moved in line with the HPI for detached houses in the Welwyn Hatfield local authority area.
• The September 2021 sale price of £790,000 represented a fair market value for the property.
