18 THE HOLDINGS 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 18 THE HOLDINGS sales from November 1997 and March 2021 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 1997 sale was for 74% below the HPI. So the extrapolation line tracks at 74% below the HPI over time, until the March 2021 sale, where it rises to 7% below the HPI. The line then continues to track at 7% below the HPI.

What might 18 THE HOLDINGS be worth now?

18 THE HOLDINGS might now be worth an estimated £837,182.

This is based on house price inflation of 6%, between March 2021 and December 2024, 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 6% inflationary increase is applied to the most recent sale price for 18 THE HOLDINGS of £790,000 on 11th March 2021. For the value to have increased from £790,000 to £837,182 over the two years and three months to December 2024, the following assumptions must hold true:

• The value of 18 THE HOLDINGS has moved in line with the HPI for detached houses in the Welwyn Hatfield local authority area.
• The March 2021 sale price of £790,000 represented a fair market value for the property.
