MAYFIELD 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 two MAYFIELD sales from April 1998 and February 2016 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 1998 sale was for 117% above the HPI. So the extrapolation line tracks at 117% above the HPI over time, until the February 2016 sale, where it falls to 62% above the HPI. The line then continues to track at 62% above the HPI.

What might MAYFIELD be worth now?

MAYFIELD might now be worth an estimated £1,259,910.

This is based on house price inflation of 27.3%, between February 2016 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 27.3% inflationary increase is applied to the most recent sale price for MAYFIELD of £990,000 on 10th February 2016. For the value to have increased from £990,000 to £1,259,910 over the nine years to February 2025, the following assumptions must hold true:

• The value of MAYFIELD has moved in line with the HPI for detached houses in the North Hertfordshire local authority area.
• The February 2016 sale price of £990,000 represented a fair market value for the property.
• The size, condition, and specification of MAYFIELD has not materially changed since February 2016.
