25 THORNEYDENE GARDENS Price Paid vs. HPI Average

The below graph shows the average detached house price in the South Kesteven local authority area over time, sourced from the HPI. The two 25 THORNEYDENE GARDENS sales from November 2009 and June 2017 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 2009 sale was for 17% below the HPI. So the extrapolation line tracks at 17% below the HPI over time, until the June 2017 sale, where it rises to 10% below the HPI. The line then continues to track at 10% below the HPI.

What might 25 THORNEYDENE GARDENS be worth now?

This is based on house price inflation of 32.5%, between June 2017 and December 2024, for detached houses, in the South Kesteven local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 32.5% inflationary increase is applied to the most recent sale price for 25 THORNEYDENE GARDENS of £249,950 on 23rd June 2017. For the value to have increased from £249,950 to £331,082 over the six years and six months to December 2024, the following assumptions must hold true:
