17 MOUNT BOONE Price Paid vs. HPI Average

The below graph shows the average detached house price in the South Hams local authority area over time, sourced from the HPI. The two 17 MOUNT BOONE sales from February 2002 and October 2012 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 February 2002 sale was for 324% above the HPI. So the extrapolation line tracks at 324% above the HPI over time, until the October 2012 sale, where it rises to 489% above the HPI. The line then continues to track at 489% above the HPI.

What might 17 MOUNT BOONE be worth now?

17 MOUNT BOONE might now be worth an estimated £3,388,707.

This is based on house price inflation of 50.6%, between October 2012 and December 2024, for detached houses, in the South Hams local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 50.6% inflationary increase is applied to the most recent sale price for 17 MOUNT BOONE of £2,250,000 on 31st October 2012. For the value to have increased from £2,250,000 to £3,388,707 over the eleven years and ten months to December 2024, the following assumptions must hold true:

• The value of 17 MOUNT BOONE has moved in line with the HPI for detached houses in the South Hams local authority area.
• The October 2012 sale price of £2,250,000 represented a fair market value for the property.
