31 ALLANSON ROAD 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 four 31 ALLANSON ROAD sales between November 1995 and September 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 January 2007 sale was for 89% above the HPI. So the extrapolation line tracks at 89% above the HPI over time, until the September 2016 sale, where it falls to 64% above the HPI. The line then continues to track at 64% above the HPI.

What might 31 ALLANSON ROAD be worth now?

31 ALLANSON ROAD might now be worth an estimated £500,361.

This is based on house price inflation of 52.5%, between September 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 52.5% inflationary increase is applied to the most recent sale price for 31 ALLANSON ROAD of £328,000 on 27th September 2016. For the value to have increased from £328,000 to £500,361 over the nine years and seven months to February 2025, the following assumptions must hold true:

• The value of 31 ALLANSON ROAD has moved in line with the HPI for detached houses in the Conwy local authority area.
• The September 2016 sale price of £328,000 represented a fair market value for the property.
