14 STREAM PARK Price Paid vs. HPI Average

The below graph shows the average detached house price in the Mid Sussex local authority area over time, sourced from the HPI. The two 14 STREAM PARK sales from April 1996 and December 2017 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 April 1996 sale was for 26% below the HPI. So the extrapolation line tracks at 26% below the HPI over time, until the December 2017 sale, where it rises to 2% below the HPI. The line then continues to track at 2% below the HPI.

What might 14 STREAM PARK be worth now?

14 STREAM PARK might now be worth an estimated £735,534.

This is based on house price inflation of 21.1%, between December 2017 and February 2025, for detached houses, in the Mid Sussex local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 21.1% inflationary increase is applied to the most recent sale price for 14 STREAM PARK of £607,500 on 15th December 2017. For the value to have increased from £607,500 to £735,534 over the eight years and ten months to February 2025, the following assumptions must hold true:

• The value of 14 STREAM PARK has moved in line with the HPI for detached houses in the Mid Sussex local authority area.
• The December 2017 sale price of £607,500 represented a fair market value for the property.
• The size, condition, and specification of 14 STREAM PARK has not materially changed since December 2017.
