25 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 25 SAYER WAY sales between October 2013 and August 2024 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 October 2017 sale was for 4% below the HPI. So the extrapolation line tracks at 4% below the HPI over time, until the August 2024 sale, where it rises to 20% above the HPI. The line then continues to track at 20% above the HPI.

What might 25 SAYER WAY be worth now?

25 SAYER WAY might now be worth an estimated £556,156.

This is based on house price inflation of 3%, between August 2024 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% inflationary increase is applied to the most recent sale price for 25 SAYER WAY of £540,000 on 29th August 2024. For the value to have increased from £540,000 to £556,156 over the one year and six months to February 2025, the following assumptions must hold true:

• The value of 25 SAYER WAY has moved in line with the HPI for semi-detached houses in the North Hertfordshire local authority area.
• The August 2024 sale price of £540,000 represented a fair market value for the property.
