11 ROYAL OAK CLOSE 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 three 11 ROYAL OAK CLOSE sales between May 2010 and May 2017 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 February 2013 sale was for 54% above the HPI. So the extrapolation line tracks at 54% above the HPI over time, until the May 2017 sale, where it rises to 64% above the HPI. The line then continues to track at 64% above the HPI.

What might 11 ROYAL OAK CLOSE be worth now?

11 ROYAL OAK CLOSE might now be worth an estimated £323,428.

This is based on house price inflation of 61.7%, between May 2017 and December 2024, 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 61.7% inflationary increase is applied to the most recent sale price for 11 ROYAL OAK CLOSE of £200,000 on 5th May 2017. For the value to have increased from £200,000 to £323,428 over the six years and five months to December 2024, the following assumptions must hold true:
