18 MOUNT PLEASANT 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 two 18 MOUNT PLEASANT LANE sales from June 2014 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 June 2014 sale was for 40% below the HPI. So the extrapolation line tracks at 40% below the HPI over time, until the September 2021 sale, where it falls to 49% below the HPI. The line then continues to track at 49% below the HPI.

What might 18 MOUNT PLEASANT LANE be worth now?

18 MOUNT PLEASANT LANE might now be worth an estimated £474,295.

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 18 MOUNT PLEASANT LANE of £450,000 on 30th September 2021. For the value to have increased from £450,000 to £474,295 over the four years and seven months to February 2025, the following assumptions must hold true:

  • The value of 18 MOUNT PLEASANT LANE has moved in line with the HPI for detached houses in the Welwyn Hatfield local authority area.
  • The September 2021 sale price of £450,000 represented a fair market value for the property.
  • The size, condition, and specification of 18 MOUNT PLEASANT LANE has not materially changed since September 2021.
