13 GLENDALE 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 four 13 GLENDALE sales between September 1999 and October 2014 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 April 2004 sale was for 2% below the HPI. So the extrapolation line tracks at 2% below the HPI over time, until the October 2014 sale, where it falls to 6% below the HPI. The line then continues to track at 6% below the HPI.

What might 13 GLENDALE be worth now?

13 GLENDALE might now be worth an estimated £486,476.

This is based on house price inflation of 50.1%, between October 2014 and December 2024, 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 50.1% inflationary increase is applied to the most recent sale price for 13 GLENDALE of £324,000 on 31st October 2014. For the value to have increased from £324,000 to £486,476 over the nine years and ten months to December 2024, the following assumptions must hold true:

• The value of 13 GLENDALE has moved in line with the HPI for semi-detached houses in the Sevenoaks local authority area.
• The October 2014 sale price of £324,000 represented a fair market value for the property.
• The size, condition, and specification of 13 GLENDALE has not materially changed since October 2014.
