11 THE WARREN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Sutton local authority area over time, sourced from the HPI. The two 11 THE WARREN sales from January 2004 and December 2008 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 January 2004 sale was for 2% above the HPI. So the extrapolation line tracks at 2% above the HPI over time, until the December 2008 sale, where it rises to 22% above the HPI. The line then continues to track at 22% above the HPI.

What might 11 THE WARREN be worth now?

The 107.4% inflationary increase is applied to the most recent sale price for 11 THE WARREN of £585,000 on 10th December 2008. For the value to have increased from £585,000 to £1,213,022 over the seventeen years and ten months to February 2025, the following assumptions must hold true:
