10 CHARNOCK Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Sevenoaks local authority area over time, sourced from the HPI. The two 10 CHARNOCK sales from September 2004 and November 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 September 2004 sale was for 11% below the HPI. So the extrapolation line tracks at 11% below the HPI over time, until the November 2018 sale, where it falls to 12% below the HPI. The line then continues to track at 12% below the HPI.

What might 10 CHARNOCK be worth now?

10 CHARNOCK might now be worth an estimated £488,234.

This is based on house price inflation of 32%, between November 2018 and May 2026, for semi-detached houses, in the Sevenoaks local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 32% inflationary increase is applied to the most recent sale price for 10 CHARNOCK of £370,000 on 22nd November 2018. For the value to have increased from £370,000 to £488,234 over the eight years and six months to May 2026, the following assumptions must hold true:

  • The value of 10 CHARNOCK has moved in line with the HPI for semi-detached houses in the Sevenoaks local authority area.
  • The November 2018 sale price of £370,000 represented a fair market value for the property.
  • The size, condition, and specification of 10 CHARNOCK has not materially changed since November 2018.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
