18 JASPER CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The four 18 JASPER CLOSE sales between July 1995 and November 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 October 2010 sale was for 71% below the HPI. So the extrapolation line tracks at 71% below the HPI over time, until the November 2017 sale, where it rises to 36% below the HPI. The line then continues to track at 36% below the HPI.

What might 18 JASPER CLOSE be worth now?

This is based on house price inflation of 37.5%, between November 2017 and February 2025, for detached houses, in the Cardiff local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 37.5% inflationary increase is applied to the most recent sale price for 18 JASPER CLOSE of £245,000 on 8th November 2017. For the value to have increased from £245,000 to £336,921 over the eight years and nine months to February 2025, the following assumptions must hold true:
