21 CASTLE AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Thanet local authority area over time, sourced from the HPI. The two 21 CASTLE AVENUE sales from September 2009 and November 2012 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 September 2009 sale roughly matched the HPI. So the extrapolation line tracks roughly in line with the HPI over time, until the November 2012 sale, where it rises to 16% above the HPI. The line then continues to track at 16% above the HPI.

What might 21 CASTLE AVENUE be worth now?

This is based on house price inflation of 98.2%, between November 2012 and February 2025, for detached houses, in the Thanet local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 98.2% inflationary increase is applied to the most recent sale price for 21 CASTLE AVENUE of £285,000 on 30th November 2012. For the value to have increased from £285,000 to £564,991 over the thirteen years and nine months to February 2025, the following assumptions must hold true:
