THE BOAT HOUSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Rhondda Cynon Taf local authority area over time, sourced from the HPI. The four THE BOAT HOUSE sales between December 1996 and September 2009 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 July 2005 sale was for 87% above the HPI. So the extrapolation line tracks at 87% above the HPI over time, until the September 2009 sale, where it rises to 93% above the HPI. The line then continues to track at 93% above the HPI.

What might THE BOAT HOUSE be worth now?

THE BOAT HOUSE might now be worth an estimated £514,481.

This is based on house price inflation of 87.1%, between September 2009 and February 2025, for 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 87.1% inflationary increase is applied to the most recent sale price for THE BOAT HOUSE of £275,000 on 10th September 2009. For the value to have increased from £275,000 to £514,481 over the sixteen years and seven months to February 2025, the following assumptions must hold true:

• The value of THE BOAT HOUSE has moved in line with the HPI for detached houses in the Rhondda Cynon Taf local authority area.
• The September 2009 sale price of £275,000 represented a fair market value for the property.
• The size, condition, and specification of THE BOAT HOUSE has not materially changed since September 2009.
