21 TAN YR ALLT AVENUE 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 two 21 TAN YR ALLT AVENUE sales from August 2001 and June 2005 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 August 2001 sale was for 48% below the HPI. So the extrapolation line tracks at 48% below the HPI over time, until the June 2005 sale, where it rises to 25% below the HPI. The line then continues to track at 25% below the HPI.

What might 21 TAN YR ALLT AVENUE be worth now?

This is based on house price inflation of 63.3%, between June 2005 and December 2024, 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 63.3% inflationary increase is applied to the most recent sale price for 21 TAN YR ALLT AVENUE of £138,000 on 24th June 2005. For the value to have increased from £138,000 to £225,378 over the eighteen years and six months to December 2024, the following assumptions must hold true:
