25 OLD PORT ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Vale of Glamorgan local authority area over time, sourced from the HPI. The three 25 OLD PORT ROAD sales between August 1996 and December 2020 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 January 1999 sale was for 81% above the HPI. So the extrapolation line tracks at 81% above the HPI over time, until the December 2020 sale, where it falls to 45% above the HPI. The line then continues to track at 45% above the HPI.

What might 25 OLD PORT ROAD be worth now?

This is based on house price inflation of 20.3%, between December 2020 and February 2025, for detached houses, in the Vale of Glamorgan local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 20.3% inflationary increase is applied to the most recent sale price for 25 OLD PORT ROAD of £620,000 on 3rd December 2020. For the value to have increased from £620,000 to £745,623 over the five years and ten months to February 2025, the following assumptions must hold true:
