15 FERN GROVE 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 15 FERN GROVE sales from June 1997 and January 2015 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 1997 sale was for 33% above the HPI. So the extrapolation line tracks at 33% above the HPI over time, until the January 2015 sale, where it falls to 26% above the HPI. The line then continues to track at 26% above the HPI.

What might 15 FERN GROVE be worth now?

15 FERN GROVE might now be worth an estimated £1,178,862.

This is based on house price inflation of 42%, between January 2015 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 42% inflationary increase is applied to the most recent sale price for 15 FERN GROVE of £830,000 on 8th January 2015. For the value to have increased from £830,000 to £1,178,862 over the nine years and eleven months to February 2025, the following assumptions must hold true:

• The value of 15 FERN GROVE has moved in line with the HPI for detached houses in the Welwyn Hatfield local authority area.
• The January 2015 sale price of £830,000 represented a fair market value for the property.
