THE WARREN Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Mid Sussex local authority area over time, sourced from the HPI. The five THE WARREN sales between December 2004 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 November 2021 sale was for 11% below the HPI. So the extrapolation line tracks at 11% below the HPI over time, until the April 2024 sale, where it rises to 8% below the HPI. The line then continues to track at 8% below the HPI.

What might THE WARREN be worth now?

THE WARREN might now be worth an estimated £420,986.

This is based on house price inflation of 7.1%, between April 2024 and December 2024, for semi-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 7.1% inflationary increase is applied to the most recent sale price for THE WARREN of £393,000 on 25th April 2024. For the value to have increased from £393,000 to £420,986 over the four months to December 2024, the following assumptions must hold true:

• The value of THE WARREN has moved in line with the HPI for semi-detached houses in the Mid Sussex local authority area.
• The April 2024 sale price of £393,000 represented a fair market value for the property.
• The size, condition, and specification of THE WARREN has not materially changed since April 2024.
