17 LLWYN ONN Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Rhondda Cynon Taf local authority area over time, sourced from the HPI. The two 17 LLWYN ONN sales from September 1996 and July 1998 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 September 1996 sale was for 97% above the HPI. So the extrapolation line tracks at 97% above the HPI over time, until the July 1998 sale, where it falls to 92% above the HPI. The line then continues to track at 92% above the HPI.

What might 17 LLWYN ONN be worth now?

17 LLWYN ONN might now be worth an estimated £264,627.

This is based on house price inflation of 413.5%, between July 1998 and June 2025, for terraced 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 413.5% inflationary increase is applied to the most recent sale price for 17 LLWYN ONN of £51,535 on 1st July 1998. For the value to have increased from £51,535 to £264,627 over the 27 years and one month to June 2025, the following assumptions must hold true:
