18 GREGORY 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 two 18 GREGORY AVENUE sales from March 2008 and June 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 March 2008 sale was for 66% above the HPI. So the extrapolation line tracks at 66% above the HPI over time, until the June 2016 sale, where it rises to 84% above the HPI. The line then continues to track at 84% above the HPI.

What might 18 GREGORY AVENUE be worth now?

This is based on house price inflation of 49.4%, between June 2016 and February 2025, 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).

The 49.4% inflationary increase is applied to the most recent sale price for 18 GREGORY AVENUE of £259,000 on 14th June 2016. For the value to have increased from £259,000 to £386,991 over the nine years and four months to February 2025, the following assumptions must hold true:
