11 SMITH 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 11 SMITH AVENUE sales between August 1998 and July 2018 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 2009 sale was for 1% above the HPI. So the extrapolation line tracks at 1% above the HPI over time, until the July 2018 sale, where it rises to 6% above the HPI. The line then continues to track at 6% above the HPI.

What might 11 SMITH AVENUE be worth now?

This is based on house price inflation of 39.1%, between July 2018 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 39.1% inflationary increase is applied to the most recent sale price for 11 SMITH AVENUE of £161,000 on 2nd July 2018. For the value to have increased from £161,000 to £223,996 over the seven years and five months to February 2025, the following assumptions must hold true:

• The value of 11 SMITH AVENUE has moved in line with the HPI for semi-detached houses in the Conwy local authority area.
