1 MARDLEY HEIGHTS 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 two 1 MARDLEY HEIGHTS sales from June 2008 and May 2021 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 June 2008 sale was for 9% above the HPI. So the extrapolation line tracks at 9% above the HPI over time, until the May 2021 sale, where it falls to 7% below the HPI. The line then continues to track at 7% below the HPI.

What might 1 MARDLEY HEIGHTS be worth now?

This is based on house price inflation of 7.7%, between May 2021 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 7.7% inflationary increase is applied to the most recent sale price for 1 MARDLEY HEIGHTS of £810,500 on 17th May 2021. For the value to have increased from £810,500 to £873,119 over the four years and three months to February 2025, the following assumptions must hold true:
