12 COLBRON 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 four 12 COLBRON CLOSE sales between January 1999 and September 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 July 2005 sale was for 65% above the HPI. So the extrapolation line tracks at 65% above the HPI over time, until the September 2024 sale, where it falls to 49% above the HPI. The line then continues to track at 49% above the HPI.

What might 12 COLBRON CLOSE be worth now?

This is based on house price deflation of 0.3%, between September 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 0.3% deflationary decrease is applied to the most recent sale price for 12 COLBRON CLOSE of £690,000 on 17th September 2024. For the value to have decreased from £690,000 to £687,878 over the one year and seven months to February 2025, the following assumptions must hold true:
