20 WALTON HEATH Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Milton Keynes local authority area over time, sourced from the HPI. The two 20 WALTON HEATH sales from May 2003 and February 2010 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 May 2003 sale was for 31% above the HPI. So the extrapolation line tracks at 31% above the HPI over time, until the February 2010 sale, where it falls to 17% above the HPI. The line then continues to track at 17% above the HPI.

What might 20 WALTON HEATH be worth now?

The 106.4% inflationary increase is applied to the most recent sale price for 20 WALTON HEATH of £186,000 on 11th February 2010. For the value to have increased from £186,000 to £383,861 over the thirteen years and two months to December 2024, the following assumptions must hold true:
