26 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 26 LEWIS STREET sales from January 1996 and December 2013 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 January 1996 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the December 2013 sale, where it rises to 38% above the HPI. The line then continues to track at 38% above the HPI.

What might 26 LEWIS STREET be worth now?

26 LEWIS STREET might now be worth an estimated £272,166.

This is based on house price inflation of 90.3%, between December 2013 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 90.3% inflationary increase is applied to the most recent sale price for 26 LEWIS STREET of £143,000 on 13th December 2013. For the value to have increased from £143,000 to £272,166 over the twelve years and ten months to February 2025, the following assumptions must hold true:
