ILKERTON 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 ILKERTON sales from June 2000 and November 2019 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 June 2000 sale was for 169% above the HPI. So the extrapolation line tracks at 169% above the HPI over time, until the November 2019 sale, where it falls to 70% above the HPI. The line then continues to track at 70% above the HPI.

What might ILKERTON be worth now?

ILKERTON might now be worth an estimated £1,598,550.

This is based on house price inflation of 9.9%, between November 2019 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 9.9% inflationary increase is applied to the most recent sale price for ILKERTON of £1,455,000 on 1st November 2019. For the value to have increased from £1,455,000 to £1,598,550 over the six years and nine months to February 2025, the following assumptions must hold true:

• The value of ILKERTON has moved in line with the HPI for detached houses in the Welwyn Hatfield local authority area.
• The November 2019 sale price of £1,455,000 represented a fair market value for the property.
• The size, condition, and specification of ILKERTON has not materially changed since November 2019.
