30 HILLSIDE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Horsham local authority area over time, sourced from the HPI. The three 30 HILLSIDE sales between October 1998 and March 2007 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 2005 sale was for 41% below the HPI. So the extrapolation line tracks at 41% below the HPI over time, until the March 2007 sale, where it rises to 31% below the HPI. The line then continues to track at 31% below the HPI.

What might 30 HILLSIDE be worth now?

30 HILLSIDE might now be worth an estimated £528,979.

This is based on house price inflation of 75.2%, between March 2007 and May 2026, for detached houses, in the Horsham local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 75.2% inflationary increase is applied to the most recent sale price for 30 HILLSIDE of £302,000 on 14th March 2007. For the value to have increased from £302,000 to £528,979 over the eighteen years and ten months to May 2026, the following assumptions must hold true:

• The value of 30 HILLSIDE has moved in line with the HPI for detached houses in the Horsham local authority area.
• The March 2007 sale price of £302,000 represented a fair market value for the property.
• The size, condition, and specification of 30 HILLSIDE has not materially changed since March 2007.
