18 PEN Y GAER Price Paid vs. HPI Average

The below graph shows the average detached house price in the Conwy local authority area over time, sourced from the HPI. The three 18 PEN Y GAER sales between May 1999 and July 2016 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 April 2000 sale was for 3% below the HPI. So the extrapolation line tracks at 3% below the HPI over time, until the July 2016 sale, where it rises to 37% above the HPI. The line then continues to track at 37% above the HPI.

What might 18 PEN Y GAER be worth now?

This is based on house price inflation of 48.7%, between July 2016 and February 2025, for detached houses, in the Conwy local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 48.7% inflationary increase is applied to the most recent sale price for 18 PEN Y GAER of £280,500 on 22nd July 2016. For the value to have increased from £280,500 to £417,154 over the nine years and five months to February 2025, the following assumptions must hold true:

• The value of 18 PEN Y GAER has moved in line with the HPI for detached houses in the Conwy local authority area.
• The July 2016 sale price of £280,500 represented a fair market value for the property.
