20 MENDLESHAM 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 four 20 MENDLESHAM sales between January 1997 and May 2018 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 October 2014 sale was for 16% below the HPI. So the extrapolation line tracks at 16% below the HPI over time, until the May 2018 sale, where it falls to 23% below the HPI. The line then continues to track at 23% below the HPI.

What might 20 MENDLESHAM be worth now?

The 13.3% inflationary increase is applied to the most recent sale price for 20 MENDLESHAM of £635,000 on 30th May 2018. For the value to have increased from £635,000 to £719,328 over the seven years and three months to February 2025, the following assumptions must hold true:
