LEASIDE HOUSE 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 LEASIDE HOUSE sales from May 1998 and October 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 May 1998 sale was for 105% above the HPI. So the extrapolation line tracks at 105% above the HPI over time, until the October 2022 sale, where it rises to 106% above the HPI. The line then continues to track at 106% above the HPI.

What might LEASIDE HOUSE be worth now?

LEASIDE HOUSE might now be worth an estimated £1,929,411.

This is based on house price deflation of 3.5%, between October 2022 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 3.5% deflationary decrease is applied to the most recent sale price for LEASIDE HOUSE of £2,000,000 on 13th October 2022. For the value to have decreased from £2,000,000 to £1,929,411 over the three years and eight months to February 2025, the following assumptions must hold true:

  • The value of LEASIDE HOUSE has moved in line with the HPI for detached houses in the Welwyn Hatfield local authority area.
  • The October 2022 sale price of £2,000,000 represented a fair market value for the property.
  • The size, condition, and specification of LEASIDE HOUSE has not materially changed since October 2022.
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.
