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 90 COLE GREEN LANE sales from November 2009 and May 2016 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 2009 sale was for 23% below the HPI. So the extrapolation line tracks at 23% below the HPI over time, until the May 2016 sale, where it rises to 39% above the HPI. The line then continues to track at 39% above the HPI.
90 COLE GREEN LANE might now be worth an estimated £704,356.
This is based on house price inflation of 20.4%, between May 2016 and July 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 20.4% inflationary increase is applied to the most recent sale price for 90 COLE GREEN LANE of £585,000 on 10th May 2016. For the value to have increased from £585,000 to £704,356 over the eight years and ten months to July 2025, the following assumptions must hold true:
