The below graph shows the average detached house price in the Caerphilly local authority area over time, sourced from the HPI. The two 1 GROSMONT CLOSE sales from September 2004 and March 2009 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 September 2004 sale was for 23% above the HPI. So the extrapolation line tracks at 23% above the HPI over time, until the March 2009 sale, where it falls to 19% above the HPI. The line then continues to track at 19% above the HPI.
1 GROSMONT CLOSE might now be worth an estimated £367,379.
This is based on house price inflation of 98.6%, between March 2009 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 98.6% inflationary increase is applied to the most recent sale price for 1 GROSMONT CLOSE of £185,000 on 27th March 2009. For the value to have increased from £185,000 to £367,379 over the fourteen years and three months to December 2024, the following assumptions must hold true:
