8 PENTWYN AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Caerphilly local authority area over time, sourced from the HPI. The four 8 PENTWYN AVENUE sales between November 2009 and November 2022 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 October 2021 sale was for 86% above the HPI. So the extrapolation line tracks at 86% above the HPI over time, until the November 2022 sale, where it falls to 75% above the HPI. The line then continues to track at 75% above the HPI.

What might 8 PENTWYN AVENUE be worth now?

This is based on house price inflation of 4.7%, between November 2022 and March 2025, for semi-detached houses, in the Caerphilly local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 4.7% inflationary increase is applied to the most recent sale price for 8 PENTWYN AVENUE of £327,500 on 28th November 2022. For the value to have increased from £327,500 to £342,968 over the three years and eight months to March 2025, the following assumptions must hold true:
