GREENOAKS 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 GREENOAKS sales from May 2008 and January 2015 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 May 2008 sale was for 19% below the HPI. So the extrapolation line tracks at 19% below the HPI over time, until the January 2015 sale, where it falls to 24% below the HPI. The line then continues to track at 24% below the HPI.

What might GREENOAKS be worth now?

GREENOAKS might now be worth an estimated £554,744.

This is based on house price inflation of 38.7%, between January 2015 and June 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 38.7% inflationary increase is applied to the most recent sale price for GREENOAKS of £400,000 on 9th January 2015. For the value to have increased from £400,000 to £554,744 over the nine years and seven months to June 2025, the following assumptions must hold true:

• The value of GREENOAKS has moved in line with the HPI for detached houses in the Mid Sussex local authority area.
• The January 2015 sale price of £400,000 represented a fair market value for the property.
• The size, condition, and specification of GREENOAKS has not materially changed since January 2015.
