18 BRYNGLAS 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 18 BRYNGLAS sales from October 2004 and June 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 October 2004 sale was for 38% below the HPI. So the extrapolation line tracks at 38% below the HPI over time, until the June 2017 sale, where it falls to 48% below the HPI. The line then continues to track at 48% below the HPI.

What might 18 BRYNGLAS be worth now?

18 BRYNGLAS might now be worth an estimated £160,389.

This is based on house price inflation of 60.4%, between June 2017 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 60.4% inflationary increase is applied to the most recent sale price for 18 BRYNGLAS of £100,000 on 16th June 2017. For the value to have increased from £100,000 to £160,389 over the eight years and four months to February 2025, the following assumptions must hold true:

• The value of 18 BRYNGLAS has moved in line with the HPI for detached houses in the Caerphilly local authority area.
• The June 2017 sale price of £100,000 represented a fair market value for the property.
