2 MOUNT KEEN Price Paid vs. HPI Average

The below graph shows the average detached house price in the North Hertfordshire local authority area over time, sourced from the HPI. The two 2 MOUNT KEEN sales from February 2003 and October 2012 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% below the HPI. So the extrapolation line tracks at 5% below the HPI over time, until the October 2012 sale, where it falls to 22% below the HPI. The line then continues to track at 22% below the HPI.

What might 2 MOUNT KEEN be worth now?

2 MOUNT KEEN might now be worth an estimated £598,930.

This is based on house price inflation of 72.4%, between October 2012 and July 2025, for 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 72.4% inflationary increase is applied to the most recent sale price for 2 MOUNT KEEN of £347,500 on 31st October 2012. For the value to have increased from £347,500 to £598,930 over the thirteen years and three months to July 2025, the following assumptions must hold true:

• The value of 2 MOUNT KEEN has moved in line with the HPI for detached houses in the North Hertfordshire local authority area.
• The October 2012 sale price of £347,500 represented a fair market value for the property.
