17 GRENHAM BAY AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Thanet local authority area over time, sourced from the HPI. The two 17 GRENHAM BAY AVENUE sales from November 1999 and March 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 November 1999 sale was for 38% above the HPI. So the extrapolation line tracks at 38% above the HPI over time, until the March 2012 sale, where it rises to 46% above the HPI. The line then continues to track at 46% above the HPI.

What might 17 GRENHAM BAY AVENUE be worth now?

This is based on house price inflation of 113%, between March 2012 and February 2025, for semi-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 113% inflationary increase is applied to the most recent sale price for 17 GRENHAM BAY AVENUE of £227,500 on 23rd March 2012. For the value to have increased from £227,500 to £484,636 over the thirteen years and one month to February 2025, the following assumptions must hold true:
