5 CALDER AVENUE 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 three 5 CALDER AVENUE sales between July 2002 and October 2019 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 November 2013 sale was for 50% above the HPI. So the extrapolation line tracks at 50% above the HPI over time, until the October 2019 sale, where it falls to 11% above the HPI. The line then continues to track at 11% above the HPI.

What might 5 CALDER AVENUE be worth now?

This is based on house price inflation of 10.1%, between October 2019 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 10.1% inflationary increase is applied to the most recent sale price for 5 CALDER AVENUE of £950,000 on 18th October 2019. For the value to have increased from £950,000 to £1,045,682 over the six years and eight months to February 2025, the following assumptions must hold true:
