9 BRYN RHOSYN 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 9 BRYN RHOSYN sales from June 1999 and March 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 June 1999 sale was for 15% above the HPI. So the extrapolation line tracks at 15% above the HPI over time, until the March 2016 sale, where it rises to 21% above the HPI. The line then continues to track at 21% above the HPI.

What might 9 BRYN RHOSYN be worth now?

9 BRYN RHOSYN might now be worth an estimated £633,007.

This is based on house price inflation of 44.2%, between March 2016 and February 2025, 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 44.2% inflationary increase is applied to the most recent sale price for 9 BRYN RHOSYN of £439,000 on 30th March 2016. For the value to have increased from £439,000 to £633,007 over the nine years and one month to February 2025, the following assumptions must hold true:

• The value of 9 BRYN RHOSYN has moved in line with the HPI for detached houses in the Cardiff local authority area.
• The March 2016 sale price of £439,000 represented a fair market value for the property.
