JUPITER 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 JUPITER sales from December 2016 and April 2024 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 December 2016 sale was for 477% above the HPI. So the extrapolation line tracks at 477% above the HPI over time, until the April 2024 sale, where it falls to 241% above the HPI. The line then continues to track at 241% above the HPI.

What might JUPITER be worth now?

JUPITER might now be worth an estimated £3,199,090.

This is based on house price inflation of 1.7%, between April 2024 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 1.7% inflationary increase is applied to the most recent sale price for JUPITER of £3,145,000 on 24th April 2024. For the value to have increased from £3,145,000 to £3,199,090 over the one year and two months to February 2025, the following assumptions must hold true:

• The value of JUPITER has moved in line with the HPI for detached houses in the Welwyn Hatfield local authority area.
• The April 2024 sale price of £3,145,000 represented a fair market value for the property.
• The size, condition, and specification of JUPITER has not materially changed since April 2024.
