15 LON Y FFIN Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Cardiff local authority area over time, sourced from the HPI. The two 15 LON Y FFIN sales from September 2017 and March 2023 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 September 2017 sale was for 20% below the HPI. So the extrapolation line tracks at 20% below the HPI over time, until the March 2023 sale, where it rises to 11% below the HPI. The line then continues to track at 11% below the HPI.

What might 15 LON Y FFIN be worth now?

This is based on house price inflation of 2.9%, between March 2023 and February 2025, for semi-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 2.9% inflationary increase is applied to the most recent sale price for 15 LON Y FFIN of £277,500 on 10th March 2023. For the value to have increased from £277,500 to £285,558 over the two years and one month to February 2025, the following assumptions must hold true:

• The value of 15 LON Y FFIN has moved in line with the HPI for semi-detached houses in the Cardiff local authority area.
• The March 2023 sale price of £277,500 represented a fair market value for the property.
