175 PARKWAY Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The three 175 PARKWAY sales between August 1995 and May 2004 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 September 1997 sale was for 20% above the HPI. So the extrapolation line tracks at 20% above the HPI over time, until the May 2004 sale, where it rises to 29% above the HPI. The line then continues to track at 29% above the HPI.

What might 175 PARKWAY be worth now?

This is based on house price inflation of 110.7%, between May 2004 and July 2025, for terraced 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 110.7% inflationary increase is applied to the most recent sale price for 175 PARKWAY of £239,950 on 6th May 2004. For the value to have increased from £239,950 to £505,463 over the twenty years and ten months to July 2025, the following assumptions must hold true:
