ROSSLYN 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 ROSSLYN sales from August 2003 and December 2015 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 August 2003 sale was for 23% below the HPI. So the extrapolation line tracks at 23% below the HPI over time, until the December 2015 sale, where it rises to 2% below the HPI. The line then continues to track at 2% below the HPI.

What might ROSSLYN be worth now?

ROSSLYN might now be worth an estimated £305,028.

This is based on house price inflation of 70.4%, between December 2015 and February 2025, 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 70.4% inflationary increase is applied to the most recent sale price for ROSSLYN of £179,000 on 11th December 2015. For the value to have increased from £179,000 to £305,028 over the ten years and ten months to February 2025, the following assumptions must hold true:

• The value of ROSSLYN has moved in line with the HPI for detached houses in the Caerphilly local authority area.
• The December 2015 sale price of £179,000 represented a fair market value for the property.
• The size, condition, and specification of ROSSLYN has not materially changed since December 2015.
