12 THE OAKS 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 three 12 THE OAKS sales between January 2000 and June 2009 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 January 2004 sale was for 35% below the HPI. So the extrapolation line tracks at 35% below the HPI over time, until the June 2009 sale, where it rises to 21% below the HPI. The line then continues to track at 21% below the HPI.

What might 12 THE OAKS be worth now?

12 THE OAKS might now be worth an estimated £588,188.

This is based on house price inflation of 102.8%, between June 2009 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 102.8% inflationary increase is applied to the most recent sale price for 12 THE OAKS of £290,000 on 12th June 2009. For the value to have increased from £290,000 to £588,188 over the sixteen years and four months to February 2025, the following assumptions must hold true:

• The value of 12 THE OAKS has moved in line with the HPI for detached houses in the Mid Sussex local authority area.
• The June 2009 sale price of £290,000 represented a fair market value for the property.
