12 HEOL PEN Y FAI 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 three 12 HEOL PEN Y FAI sales between July 1999 and August 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 June 2000 sale was for 19% above the HPI. So the extrapolation line tracks at 19% above the HPI over time, until the August 2014 sale, where it falls to 17% below the HPI. The line then continues to track at 17% below the HPI.

What might 12 HEOL PEN Y FAI be worth now?

This is based on house price inflation of 60.3%, between August 2014 and December 2024, 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 60.3% inflationary increase is applied to the most recent sale price for 12 HEOL PEN Y FAI of £270,000 on 15th August 2014. For the value to have increased from £270,000 to £432,867 over the nine years and eight months to December 2024, the following assumptions must hold true:
