20 HILLSIDE 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 20 HILLSIDE sales from July 1998 and March 2002 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 July 1998 sale was for 7% above the HPI. So the extrapolation line tracks at 7% above the HPI over time, until the March 2002 sale, where it rises to 60% above the HPI. The line then continues to track at 60% above the HPI.

What might 20 HILLSIDE be worth now?

20 HILLSIDE might now be worth an estimated £850,778.

This is based on house price inflation of 203.8%, between March 2002 and February 2025, 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 203.8% inflationary increase is applied to the most recent sale price for 20 HILLSIDE of £280,000 on 25th March 2002. For the value to have increased from £280,000 to £850,778 over the 23 years and one month to February 2025, the following assumptions must hold true:

• The value of 20 HILLSIDE has moved in line with the HPI for semi-detached houses in the Sevenoaks local authority area.
• The March 2002 sale price of £280,000 represented a fair market value for the property.
• The size, condition, and specification of 20 HILLSIDE has not materially changed since March 2002.
