19 HERNS LANE 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 three 19 HERNS LANE sales between August 2002 and May 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 2009 sale was for 45% below the HPI. So the extrapolation line tracks at 45% below the HPI over time, until the May 2021 sale, where it falls to 48% below the HPI. The line then continues to track at 48% below the HPI.

What might 19 HERNS LANE be worth now?

19 HERNS LANE might now be worth an estimated £492,307.

This is based on house price inflation of 7.7%, between May 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 7.7% inflationary increase is applied to the most recent sale price for 19 HERNS LANE of £457,000 on 7th May 2021. For the value to have increased from £457,000 to £492,307 over the four years and three months to February 2025, the following assumptions must hold true:

  • The value of 19 HERNS LANE has moved in line with the HPI for detached houses in the Welwyn Hatfield local authority area.
  • The May 2021 sale price of £457,000 represented a fair market value for the property.
  • The size, condition, and specification of 19 HERNS LANE has not materially changed since May 2021.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
