20 HEATHFIELD Price Paid vs. HPI Average

The below graph shows the average detached house price in the North Hertfordshire local authority area over time, sourced from the HPI. The four 20 HEATHFIELD sales between June 1997 and January 2017 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 2002 sale was for 74% above the HPI. So the extrapolation line tracks at 74% above the HPI over time, until the January 2017 sale, where it falls to 49% above the HPI. The line then continues to track at 49% above the HPI.

What might 20 HEATHFIELD be worth now?

20 HEATHFIELD might now be worth an estimated £1,159,901.

This is based on house price inflation of 19%, between January 2017 and February 2025, for detached houses, in the North Hertfordshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 19% inflationary increase is applied to the most recent sale price for 20 HEATHFIELD of £975,000 on 11th January 2017. For the value to have increased from £975,000 to £1,159,901 over the seven years and eleven months to February 2025, the following assumptions must hold true:

• The value of 20 HEATHFIELD has moved in line with the HPI for detached houses in the North Hertfordshire local authority area.
• The January 2017 sale price of £975,000 represented a fair market value for the property.
• The size, condition, and specification of 20 HEATHFIELD has not materially changed since January 2017.
