16 LEWIS STREET 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 16 LEWIS STREET sales from August 2004 and September 2005 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 2004 sale was for 30% below the HPI. So the extrapolation line tracks at 30% below the HPI over time, until the September 2005 sale, where it rises to 12% above the HPI. The line then continues to track at 12% above the HPI.

What might 16 LEWIS STREET be worth now?

This is based on house price inflation of 89.8%, between September 2005 and February 2025, 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 89.8% inflationary increase is applied to the most recent sale price for 16 LEWIS STREET of £116,000 on 26th September 2005. For the value to have increased from £116,000 to £220,187 over the twenty years and seven months to February 2025, the following assumptions must hold true:
