29 KNIGHTSWELL ROAD 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 29 KNIGHTSWELL ROAD sales from February 2003 and December 2020 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 February 2003 sale was for 5% below the HPI. So the extrapolation line tracks at 5% below the HPI over time, until the December 2020 sale, where it falls to 9% below the HPI. The line then continues to track at 9% below the HPI.

What might 29 KNIGHTSWELL ROAD be worth now?

29 KNIGHTSWELL ROAD might now be worth an estimated £470,555.

This is based on house price inflation of 22.2%, between December 2020 and June 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 22.2% inflationary increase is applied to the most recent sale price for 29 KNIGHTSWELL ROAD of £385,000 on 3rd December 2020. For the value to have increased from £385,000 to £470,555 over the five years and six months to June 2025, the following assumptions must hold true:

  • The value of 29 KNIGHTSWELL ROAD has moved in line with the HPI for detached houses in the Cardiff local authority area.
  • The December 2020 sale price of £385,000 represented a fair market value for the property.
  • The size, condition, and specification of 29 KNIGHTSWELL ROAD has not materially changed since December 2020.
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.
