22 THURNALL AVENUE 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 22 THURNALL AVENUE sales from February 2003 and February 2013 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 February 2003 sale was for 5% above the HPI. So the extrapolation line tracks at 5% above the HPI over time, until the February 2013 sale, where it falls to 18% below the HPI. The line then continues to track at 18% below the HPI.

What might 22 THURNALL AVENUE be worth now?

This is based on house price inflation of 78%, between February 2013 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 78% inflationary increase is applied to the most recent sale price for 22 THURNALL AVENUE of £210,500 on 8th February 2013. For the value to have increased from £210,500 to £374,592 over the eleven years and seven months to July 2025, the following assumptions must hold true:

• The value of 22 THURNALL AVENUE has moved in line with the HPI for semi-detached houses in the North Hertfordshire local authority area.
• The February 2013 sale price of £210,500 represented a fair market value for the property.
