3 ROUNDWOOD PARK Price Paid vs. HPI Average

The below graph shows the average detached house price in the St Albans local authority area over time, sourced from the HPI. The three 3 ROUNDWOOD PARK sales between December 1997 and December 2015 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 October 2007 sale was for 118% above the HPI. So the extrapolation line tracks at 118% above the HPI over time, until the December 2015 sale, where it falls to 100% above the HPI. The line then continues to track at 100% above the HPI.

What might 3 ROUNDWOOD PARK be worth now?

3 ROUNDWOOD PARK might now be worth an estimated £2,479,385.

This is based on house price inflation of 30.8%, between December 2015 and February 2025, for detached houses, in the St Albans local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 30.8% inflationary increase is applied to the most recent sale price for 3 ROUNDWOOD PARK of £1,895,000 on 3rd December 2015. For the value to have increased from £1,895,000 to £2,479,385 over the ten years and ten months to February 2025, the following assumptions must hold true:

• The value of 3 ROUNDWOOD PARK has moved in line with the HPI for detached houses in the St Albans local authority area.
• The December 2015 sale price of £1,895,000 represented a fair market value for the property.
• The size, condition, and specification of 3 ROUNDWOOD PARK has not materially changed since December 2015.
