20 HEATHWAY Price Paid vs. HPI Average

The below graph shows the average detached house price in the Greenwich local authority area over time, sourced from the HPI. The two 20 HEATHWAY sales from March 2003 and January 2022 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 March 2003 sale was for 63% above the HPI. So the extrapolation line tracks at 63% above the HPI over time, until the January 2022 sale, where it rises to 100% above the HPI. The line then continues to track at 100% above the HPI.

What might 20 HEATHWAY be worth now?

20 HEATHWAY might now be worth an estimated £2,015,833.

This is based on house price inflation of 3.4%, between January 2022 and December 2024, for detached houses, in the Greenwich local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 3.4% inflationary increase is applied to the most recent sale price for 20 HEATHWAY of £1,950,000 on 31st January 2022. For the value to have increased from £1,950,000 to £2,015,833 over the one year and one month to December 2024, the following assumptions must hold true:

• The value of 20 HEATHWAY has moved in line with the HPI for detached houses in the Greenwich local authority area.
• The January 2022 sale price of £1,950,000 represented a fair market value for the property.
• The size, condition, and specification of 20 HEATHWAY has not materially changed since January 2022.
