15 PARTHIA CLOSE 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 two 15 PARTHIA CLOSE sales from July 1997 and May 2006 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 1997 sale was for 32% above the HPI. So the extrapolation line tracks at 32% above the HPI over time, until the May 2006 sale, where it falls to 10% above the HPI. The line then continues to track at 10% above the HPI.

What might 15 PARTHIA CLOSE be worth now?

15 PARTHIA CLOSE might now be worth an estimated £503,685.

This is based on house price inflation of 101.9%, between May 2006 and July 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 101.9% inflationary increase is applied to the most recent sale price for 15 PARTHIA CLOSE of £249,500 on 5th May 2006. For the value to have increased from £249,500 to £503,685 over the eighteen years and ten months to July 2025, the following assumptions must hold true:

• The value of 15 PARTHIA CLOSE has moved in line with the HPI for semi-detached houses in the North Hertfordshire local authority area.
• The May 2006 sale price of £249,500 represented a fair market value for the property.
