20 CASTLE ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Folkestone and Hythe local authority area over time, sourced from the HPI. The two 20 CASTLE ROAD sales from March 2011 and February 2014 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 2011 sale was for 100% above the HPI. So the extrapolation line tracks at 100% above the HPI over time, until the February 2014 sale, where it rises to 160% above the HPI. The line then continues to track at 160% above the HPI.

What might 20 CASTLE ROAD be worth now?

20 CASTLE ROAD might now be worth an estimated £904,682.

This is based on house price inflation of 83.3%, between February 2014 and May 2026, for semi-detached houses, in the Folkestone and Hythe local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 83.3% inflationary increase is applied to the most recent sale price for 20 CASTLE ROAD of £493,500 on 18th February 2014. For the value to have increased from £493,500 to £904,682 over the eleven years and nine months to May 2026, the following assumptions must hold true:

  • The value of 20 CASTLE ROAD has moved in line with the HPI for semi-detached houses in the Folkestone and Hythe local authority area.
  • The February 2014 sale price of £493,500 represented a fair market value for the property.
  • The size, condition, and specification of 20 CASTLE ROAD has not materially changed since February 2014.
