1 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 1 LEWIS STREET sales from March 2014 and September 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 March 2014 sale was for 11% below the HPI. So the extrapolation line tracks at 11% below the HPI over time, until the September 2017 sale, where it rises to 2% above the HPI. The line then continues to track at 2% above the HPI.

What might 1 LEWIS STREET be worth now?

This is based on house price inflation of 58.6%, between September 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 58.6% inflationary increase is applied to the most recent sale price for 1 LEWIS STREET of £126,500 on 15th September 2017. For the value to have increased from £126,500 to £200,630 over the six years and nine months to December 2024, the following assumptions must hold true:
