SOUTHWICK Price Paid vs. HPI Average

The below graph shows the average detached house price in the Buckinghamshire local authority area over time, sourced from the HPI. The three SOUTHWICK sales between December 2005 and June 2021 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 2013 sale was for 111% above the HPI. So the extrapolation line tracks at 111% above the HPI over time, until the June 2021 sale, where it falls to 104% above the HPI. The line then continues to track at 104% above the HPI.

What might SOUTHWICK be worth now?

SOUTHWICK might now be worth an estimated £1,697,447.

This is based on house price inflation of 9.5%, between June 2021 and December 2024, for detached houses, in the Buckinghamshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 9.5% inflationary increase is applied to the most recent sale price for SOUTHWICK of £1,550,000 on 28th June 2021. For the value to have increased from £1,550,000 to £1,697,447 over the two years and six months to December 2024, the following assumptions must hold true:

• The value of SOUTHWICK has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The June 2021 sale price of £1,550,000 represented a fair market value for the property.
• The size, condition, and specification of SOUTHWICK has not materially changed since June 2021.
