DIGSWELL WATER MILL Price Paid vs. HPI Average

The below graph shows the average detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The two DIGSWELL WATER MILL sales from October 1996 and September 2010 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 1996 sale was for 197% above the HPI. So the extrapolation line tracks at 197% above the HPI over time, until the September 2010 sale, where it rises to 334% above the HPI. The line then continues to track at 334% above the HPI.

What might DIGSWELL WATER MILL be worth now?

DIGSWELL WATER MILL might now be worth an estimated £4,071,978.

This is based on house price inflation of 66.2%, between September 2010 and February 2025, for detached houses, in the Welwyn Hatfield local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 66.2% inflationary increase is applied to the most recent sale price for DIGSWELL WATER MILL of £2,450,000 on 1st September 2010. For the value to have increased from £2,450,000 to £4,071,978 over the fifteen years and seven months to February 2025, the following assumptions must hold true:

• The value of DIGSWELL WATER MILL has moved in line with the HPI for detached houses in the Welwyn Hatfield local authority area.
• The September 2010 sale price of £2,450,000 represented a fair market value for the property.
