31 SAYER WAY Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the North Hertfordshire local authority area over time, sourced from the HPI. The three 31 SAYER WAY sales between August 2011 and June 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 June 2014 sale was for 12% above the HPI. So the extrapolation line tracks at 12% above the HPI over time, until the June 2022 sale, which was also at 12% above the HPI.

What might 31 SAYER WAY be worth now?

This is based on house price inflation of 3.7%, between June 2022 and February 2025, for semi-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 3.7% inflationary increase is applied to the most recent sale price for 31 SAYER WAY of £500,000 on 10th June 2022. For the value to have increased from £500,000 to £518,296 over the three years and four months to February 2025, the following assumptions must hold true:

• The value of 31 SAYER WAY has moved in line with the HPI for semi-detached houses in the North Hertfordshire local authority area.
• The June 2022 sale price of £500,000 represented a fair market value for the property.
