10 DDERWEN DEG Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The two 10 DDERWEN DEG sales from June 2016 and July 2019 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 June 2016 sale was for 119% above the HPI. So the extrapolation line tracks at 119% above the HPI over time, until the July 2019 sale, where it falls to 115% above the HPI. The line then continues to track at 115% above the HPI.

What might 10 DDERWEN DEG be worth now?

10 DDERWEN DEG might now be worth an estimated £1,122,313.

This is based on house price inflation of 32%, between July 2019 and December 2024, for detached houses, in the Cardiff local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 32% inflationary increase is applied to the most recent sale price for 10 DDERWEN DEG of £850,000 on 3rd July 2019. For the value to have increased from £850,000 to £1,122,313 over the four years and seven months to December 2024, the following assumptions must hold true:

• The value of 10 DDERWEN DEG has moved in line with the HPI for detached houses in the Cardiff local authority area.
• The July 2019 sale price of £850,000 represented a fair market value for the property.
• The size, condition, and specification of 10 DDERWEN DEG has not materially changed since July 2019.
