The below graph shows the average detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The two 13 ASTWICK AVENUE sales from May 2004 and August 2009 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 2004 sale was for 37% below the HPI. So the extrapolation line tracks at 37% below the HPI over time, until the August 2009 sale, where it falls to 39% below the HPI. The line then continues to track at 39% below the HPI.
13 ASTWICK AVENUE might now be worth an estimated £570,809.
This is based on house price inflation of 100.3%, between August 2009 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 100.3% inflationary increase is applied to the most recent sale price for 13 ASTWICK AVENUE of £285,000 on 7th August 2009. For the value to have increased from £285,000 to £570,809 over the sixteen years and six months to February 2025, the following assumptions must hold true:
