18 FIRWAY Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The two 18 FIRWAY sales from May 1995 and March 2015 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 1995 sale was for 76% above the HPI. So the extrapolation line tracks at 76% above the HPI over time, until the March 2015 sale, where it falls to 62% above the HPI. The line then continues to track at 62% above the HPI.

What might 18 FIRWAY be worth now?

18 FIRWAY might now be worth an estimated £851,352.

This is based on house price inflation of 49.4%, between March 2015 and February 2025, for semi-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 49.4% inflationary increase is applied to the most recent sale price for 18 FIRWAY of £570,000 on 20th March 2015. For the value to have increased from £570,000 to £851,352 over the ten years and one month to February 2025, the following assumptions must hold true:

• The value of 18 FIRWAY has moved in line with the HPI for semi-detached houses in the Welwyn Hatfield local authority area.
• The March 2015 sale price of £570,000 represented a fair market value for the property.
• The size, condition, and specification of 18 FIRWAY has not materially changed since March 2015.
