9A NEW ROAD 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 four 9A NEW ROAD sales between January 1999 and September 2005 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 July 2001 sale was for 83% above the HPI. So the extrapolation line tracks at 83% above the HPI over time, until the September 2005 sale, where it falls to 68% above the HPI. The line then continues to track at 68% above the HPI.

What might 9A NEW ROAD be worth now?

9A NEW ROAD might now be worth an estimated £1,579,717.

This is based on house price inflation of 102.5%, between September 2005 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 102.5% inflationary increase is applied to the most recent sale price for 9A NEW ROAD of £780,000 on 9th September 2005. For the value to have increased from £780,000 to £1,579,717 over the twenty years and seven months to February 2025, the following assumptions must hold true:

• The value of 9A NEW ROAD has moved in line with the HPI for detached houses in the Welwyn Hatfield local authority area.
• The September 2005 sale price of £780,000 represented a fair market value for the property.
• The size, condition, and specification of 9A NEW ROAD has not materially changed since September 2005.
