5 HEOL IESTYN 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 two 5 HEOL IESTYN sales from November 2016 and August 2018 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 2016 sale was for 31% below the HPI. So the extrapolation line tracks at 31% below the HPI over time, until the August 2018 sale, where it rises to 3% below the HPI. The line then continues to track at 3% below the HPI.

What might 5 HEOL IESTYN be worth now?

This is based on house price inflation of 32.3%, between August 2018 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 32.3% inflationary increase is applied to the most recent sale price for 5 HEOL IESTYN of £385,000 on 15th August 2018. For the value to have increased from £385,000 to £509,465 over the seven years and six months to February 2025, the following assumptions must hold true:
