18 PENLAN ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Vale of Glamorgan local authority area over time, sourced from the HPI. The four 18 PENLAN ROAD sales between November 2016 and April 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 November 2019 sale was for 33% above the HPI. So the extrapolation line tracks at 33% above the HPI over time, until the April 2025 sale, where it falls to 7% above the HPI. The line then continues to track at 7% above the HPI.

What might 18 PENLAN ROAD be worth now?

18 PENLAN ROAD might now be worth an estimated £330,335.

This is based on house price inflation of 3.2%, between April 2025 and May 2026, for semi-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 3.2% inflationary increase is applied to the most recent sale price for 18 PENLAN ROAD of £320,000 on 25th April 2025. For the value to have increased from £320,000 to £330,335 over the eleven months to May 2026, the following assumptions must hold true:

• The value of 18 PENLAN ROAD has moved in line with the HPI for semi-detached houses in the Vale of Glamorgan local authority area.
• The April 2025 sale price of £320,000 represented a fair market value for the property.
