1B FIRWAY 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 1B FIRWAY sales from August 2002 and March 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 August 2002 sale was for 49% above the HPI. So the extrapolation line tracks at 49% above the HPI over time, until the March 2021 sale, where it falls to 3% above the HPI. The line then continues to track at 3% above the HPI.

What might 1B FIRWAY be worth now?

1B FIRWAY might now be worth an estimated £927,258.

This is based on house price inflation of 6%, between March 2021 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 6% inflationary increase is applied to the most recent sale price for 1B FIRWAY of £875,000 on 12th March 2021. For the value to have increased from £875,000 to £927,258 over the two years and three months to December 2024, the following assumptions must hold true:

• The value of 1B FIRWAY has moved in line with the HPI for detached houses in the Welwyn Hatfield local authority area.
• The March 2021 sale price of £875,000 represented a fair market value for the property.
• The size, condition, and specification of 1B FIRWAY has not materially changed since March 2021.
