21 CASTLE ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Isle of Wight local authority area over time, sourced from the HPI. The three 21 CASTLE ROAD sales between June 1996 and March 2013 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 August 1998 sale was for 37% above the HPI. So the extrapolation line tracks at 37% above the HPI over time, until the March 2013 sale, where it rises to 45% above the HPI. The line then continues to track at 45% above the HPI.

What might 21 CASTLE ROAD be worth now?

21 CASTLE ROAD might now be worth an estimated £592,260.

This is based on house price inflation of 69.2%, between March 2013 and February 2025, for detached houses, in the Isle of Wight local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 69.2% inflationary increase is applied to the most recent sale price for 21 CASTLE ROAD of £350,000 on 14th March 2013. For the value to have increased from £350,000 to £592,260 over the twelve years and one month to February 2025, the following assumptions must hold true:
