21 TYDFIL PLACE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Cardiff local authority area over time, sourced from the HPI. The three 21 TYDFIL PLACE sales between December 1997 and August 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 2006 sale was for 109% above the HPI. So the extrapolation line tracks at 109% above the HPI over time, until the August 2025 sale, where it rises to 128% above the HPI. The line then continues to track at 128% above the HPI.

What might 21 TYDFIL PLACE be worth now?

This is based on house price inflation of 2.9%, between August 2025 and May 2026, for terraced 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 21 TYDFIL PLACE of £580,000 on 29th August 2025. For the value to have increased from £580,000 to £596,715 over the one year and three months to May 2026, the following assumptions must hold true:
