18 WATERLOO GARDENS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The two 18 WATERLOO GARDENS sales from July 2004 and December 2016 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 2004 sale was for 9% below the HPI. So the extrapolation line tracks at 9% below the HPI over time, until the December 2016 sale, where it rises to 23% above the HPI. The line then continues to track at 23% above the HPI.

What might 18 WATERLOO GARDENS be worth now?

18 WATERLOO GARDENS might now be worth an estimated £635,717.

This is based on house price inflation of 43.3%, between December 2016 and March 2025, for 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 43.3% inflationary increase is applied to the most recent sale price for 18 WATERLOO GARDENS of £443,500 on 19th December 2016. For the value to have increased from £443,500 to £635,717 over the nine years and nine months to March 2025, the following assumptions must hold true:

  • The value of 18 WATERLOO GARDENS has moved in line with the HPI for detached houses in the Cardiff local authority area.
  • The December 2016 sale price of £443,500 represented a fair market value for the property.
  • The size, condition, and specification of 18 WATERLOO GARDENS has not materially changed since December 2016.
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.
