8 COED MAWR Price Paid vs. HPI Average

The below graph shows the average detached house price in the Caerphilly local authority area over time, sourced from the HPI. The two 8 COED MAWR sales from March 1998 and March 2014 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 March 1998 sale was for 3% below the HPI. So the extrapolation line tracks at 3% below the HPI over time, until the March 2014 sale, where it falls to 7% below the HPI. The line then continues to track at 7% below the HPI.

What might 8 COED MAWR be worth now?

8 COED MAWR might now be worth an estimated £287,762.

This is based on house price inflation of 81.6%, between March 2014 and December 2024, for 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 81.6% inflationary increase is applied to the most recent sale price for 8 COED MAWR of £158,500 on 20th March 2014. For the value to have increased from £158,500 to £287,762 over the nine years and three months to December 2024, the following assumptions must hold true:
