3 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 3 MOUNT KEEN sales from January 2003 and May 2007 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 January 2003 sale was for 16% below the HPI. So the extrapolation line tracks at 16% below the HPI over time, until the May 2007 sale, where it falls to 25% below the HPI. The line then continues to track at 25% below the HPI.

What might 3 MOUNT KEEN be worth now?

3 MOUNT KEEN might now be worth an estimated £578,324.

This is based on house price inflation of 87.2%, between May 2007 and February 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 87.2% inflationary increase is applied to the most recent sale price for 3 MOUNT KEEN of £309,000 on 24th May 2007. For the value to have increased from £309,000 to £578,324 over the eighteen years and three months to February 2025, the following assumptions must hold true:

• The value of 3 MOUNT KEEN has moved in line with the HPI for detached houses in the North Hertfordshire local authority area.
• The May 2007 sale price of £309,000 represented a fair market value for the property.
• The size, condition, and specification of 3 MOUNT KEEN has not materially changed since May 2007.
