18 TAN YR ALLT AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Conwy local authority area over time, sourced from the HPI. The three 18 TAN YR ALLT AVENUE sales between August 2000 and July 2006 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 May 2005 sale was for 17% above the HPI. So the extrapolation line tracks at 17% above the HPI over time, until the July 2006 sale, where it falls to 12% above the HPI. The line then continues to track at 12% above the HPI.

What might 18 TAN YR ALLT AVENUE be worth now?

This is based on house price inflation of 53.9%, between July 2006 and December 2024, for semi-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).
