The below graph shows the average semi-detached house price in the Pembrokeshire local authority area over time, sourced from the HPI. The two 16 BROOKSIDE AVENUE sales from March 2002 and October 2005 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 March 2002 sale was for 44% above the HPI. So the extrapolation line tracks at 44% above the HPI over time, until the October 2005 sale, where it falls to 41% above the HPI. The line then continues to track at 41% above the HPI.

16 BROOKSIDE AVENUE might now be worth an estimated £281,476.
This is based on house price inflation of 53.8%, between October 2005 and August 2025, for semi-detached houses, in the Pembrokeshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 53.8% inflationary increase is applied to the most recent sale price for 16 BROOKSIDE AVENUE of £183,000 on 10th October 2005. For the value to have increased from £183,000 to £281,476 over the twenty years and two months to August 2025, the following assumptions must hold true:
