15 HARCOURT ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Rhondda Cynon Taf local authority area over time, sourced from the HPI. The two 15 HARCOURT ROAD sales from January 2006 and June 2017 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 2006 sale was for 8% below the HPI. So the extrapolation line tracks at 8% below the HPI over time, until the June 2017 sale, where it rises to 19% above the HPI. The line then continues to track at 19% above the HPI.

What might 15 HARCOURT ROAD be worth now?

15 HARCOURT ROAD might now be worth an estimated £218,012.

This is based on house price inflation of 74.4%, between June 2017 and May 2026, for semi-detached houses, in the Rhondda Cynon Taf local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 74.4% inflationary increase is applied to the most recent sale price for 15 HARCOURT ROAD of £125,000 on 30th June 2017. For the value to have increased from £125,000 to £218,012 over the nine years and one month to May 2026, the following assumptions must hold true:

  • The value of 15 HARCOURT ROAD has moved in line with the HPI for semi-detached houses in the Rhondda Cynon Taf local authority area.
  • The June 2017 sale price of £125,000 represented a fair market value for the property.
  • The size, condition, and specification of 15 HARCOURT ROAD has not materially changed since June 2017.
