12 MERLIN CLOSE 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 five 12 MERLIN CLOSE sales between May 1996 and May 2025 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 May 2022 sale was for 4% below the HPI. So the extrapolation line tracks at 4% below the HPI over time, until the May 2025 sale, where it rises to 3% below the HPI. The line then continues to track at 3% below the HPI.

What might 12 MERLIN CLOSE be worth now?

12 MERLIN CLOSE might now be worth an estimated £310,049.

This is based on house price inflation of 0%, between May 2025 and June 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 0% inflationary increase is applied to the most recent sale price for 12 MERLIN CLOSE of £310,000 on 30th May 2025. For the value to have increased from £310,000 to £310,049 over the eleven months to June 2025, the following assumptions must hold true:

• The value of 12 MERLIN CLOSE has moved in line with the HPI for semi-detached houses in the Cardiff local authority area.
