11 MOSTYN ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Cardiff local authority area over time, sourced from the HPI. The two 11 MOSTYN ROAD sales from February 2008 and June 2010 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 2008 sale was for 44% below the HPI. So the extrapolation line tracks at 44% below the HPI over time, until the June 2010 sale, where it falls to 47% below the HPI. The line then continues to track at 47% below the HPI.

What might 11 MOSTYN ROAD be worth now?

11 MOSTYN ROAD might now be worth an estimated £173,154.

This is based on house price inflation of 90.3%, between June 2010 and May 2026, for semi-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 90.3% inflationary increase is applied to the most recent sale price for 11 MOSTYN ROAD of £91,000 on 4th June 2010. For the value to have increased from £91,000 to £173,154 over the sixteen years and one month to May 2026, the following assumptions must hold true:

  • The value of 11 MOSTYN ROAD has moved in line with the HPI for semi-detached houses in the Cardiff local authority area.
  • The June 2010 sale price of £91,000 represented a fair market value for the property.
  • The size, condition, and specification of 11 MOSTYN ROAD has not materially changed since June 2010.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
