51 PARKWAY 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 51 PARKWAY sales from August 2008 and August 2022 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 2008 sale was for 8% above the HPI. So the extrapolation line tracks at 8% above the HPI over time, until the August 2022 sale, where it rises to 11% above the HPI. The line then continues to track at 11% above the HPI.

What might 51 PARKWAY be worth now?

51 PARKWAY might now be worth an estimated £1,005,689.

This is based on house price deflation of 8.1%, between August 2022 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 8.1% deflationary decrease is applied to the most recent sale price for 51 PARKWAY of £1,094,000 on 30th August 2022. For the value to have decreased from £1,094,000 to £1,005,689 over the one year and eight months to December 2024, the following assumptions must hold true:
