The below graph shows the average semi-detached house price in the South Hams local authority area over time, sourced from the HPI. The four 9 MOUNT BOONE sales between September 1999 and September 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 August 2017 sale was for 342% above the HPI. So the extrapolation line tracks at 342% above the HPI over time, until the September 2018 sale, where it falls to 340% above the HPI. The line then continues to track at 340% above the HPI.
9 MOUNT BOONE might now be worth an estimated £1,639,155.
This is based on house price inflation of 31.1%, between September 2018 and December 2024, for semi-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 31.1% inflationary increase is applied to the most recent sale price for 9 MOUNT BOONE of £1,250,000 on 6th September 2018. For the value to have increased from £1,250,000 to £1,639,155 over the five years and nine months to December 2024, the following assumptions must hold true:
