HILLDOWN HOUSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Southampton local authority area over time, sourced from the HPI. The two HILLDOWN HOUSE sales from March 2017 and May 2020 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 March 2017 sale was for 9% above the HPI. So the extrapolation line tracks at 9% above the HPI over time, until the May 2020 sale, where it rises to 53% above the HPI. The line then continues to track at 53% above the HPI.

What might HILLDOWN HOUSE be worth now?

This is based on house price inflation of 16.3%, between May 2020 and February 2025, for detached houses, in the Southampton local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 16.3% inflationary increase is applied to the most recent sale price for HILLDOWN HOUSE of £550,000 on 18th May 2020. For the value to have increased from £550,000 to £639,597 over the five years and three months to February 2025, the following assumptions must hold true:

• The value of HILLDOWN HOUSE has moved in line with the HPI for detached houses in the Southampton local authority area.
