37 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 two 37 ROUNDWOOD PARK sales from November 2005 and April 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 November 2005 sale was for 84% above the HPI. So the extrapolation line tracks at 84% above the HPI over time, until the April 2007 sale, where it rises to 94% above the HPI. The line then continues to track at 94% above the HPI.

What might 37 ROUNDWOOD PARK be worth now?

37 ROUNDWOOD PARK might now be worth an estimated £2,396,882.

This is based on house price inflation of 99.7%, between April 2007 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 99.7% inflationary increase is applied to the most recent sale price for 37 ROUNDWOOD PARK of £1,200,000 on 3rd April 2007. For the value to have increased from £1,200,000 to £2,396,882 over the eighteen years and two months to February 2025, the following assumptions must hold true:

• The value of 37 ROUNDWOOD PARK has moved in line with the HPI for detached houses in the St Albans local authority area.
• The April 2007 sale price of £1,200,000 represented a fair market value for the property.
