27 MARDY CRESCENT 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 two 27 MARDY CRESCENT sales from November 2023 and November 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 2023 sale was for 40% above the HPI. So the extrapolation line tracks at 40% above the HPI over time, until the November 2025 sale, where it rises to 57% above the HPI. The line then continues to track at 57% above the HPI.

What might 27 MARDY CRESCENT be worth now?

This is based on house price inflation of 5.1%, between November 2025 and April 2026, 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 5.1% inflationary increase is applied to the most recent sale price for 27 MARDY CRESCENT of £305,000 on 14th November 2025. For the value to have increased from £305,000 to £320,406 over the one year and seven months to April 2026, the following assumptions must hold true:
