DIDDOSFA 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 three DIDDOSFA sales between July 1996 and July 2007 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 February 2005 sale was for 82% below the HPI. So the extrapolation line tracks at 82% below the HPI over time, until the July 2007 sale, where it rises to 56% below the HPI. The line then continues to track at 56% below the HPI.

What might DIDDOSFA be worth now?

DIDDOSFA might now be worth an estimated £132,842.

This is based on house price inflation of 47.6%, between July 2007 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 47.6% inflationary increase is applied to the most recent sale price for DIDDOSFA of £90,000 on 9th July 2007. For the value to have increased from £90,000 to £132,842 over the eighteen years and five months to February 2025, the following assumptions must hold true:

• The value of DIDDOSFA has moved in line with the HPI for detached houses in the Conwy local authority area.
• The July 2007 sale price of £90,000 represented a fair market value for the property.
• The size, condition, and specification of DIDDOSFA has not materially changed since July 2007.
