25 OLD CONVENT Price Paid vs. HPI Average

The below graph shows the average detached house price in the Mid Sussex local authority area over time, sourced from the HPI. The two 25 OLD CONVENT sales from December 1997 and March 2007 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 December 1997 sale was for 141% above the HPI. So the extrapolation line tracks at 141% above the HPI over time, until the March 2007 sale, where it falls to 65% below the HPI. The line then continues to track at 65% below the HPI.

What might 25 OLD CONVENT be worth now?

The 87.6% inflationary increase is applied to the most recent sale price for 25 OLD CONVENT of £137,635 on 19th March 2007. For the value to have increased from £137,635 to £258,236 over the eighteen years and one month to February 2025, the following assumptions must hold true:
