11 CASTLE ACRE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Swansea local authority area over time, sourced from the HPI. The two 11 CASTLE ACRE sales from February 2000 and May 2019 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 2000 sale was for 144% above the HPI. So the extrapolation line tracks at 144% above the HPI over time, until the May 2019 sale, where it rises to 183% above the HPI. The line then continues to track at 183% above the HPI.

What might 11 CASTLE ACRE be worth now?

11 CASTLE ACRE might now be worth an estimated £479,295.

This is based on house price inflation of 47.5%, between May 2019 and April 2026, for terraced houses, in the Swansea local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 47.5% inflationary increase is applied to the most recent sale price for 11 CASTLE ACRE of £325,000 on 24th May 2019. For the value to have increased from £325,000 to £479,295 over the seven years and one month to April 2026, the following assumptions must hold true:

  • The value of 11 CASTLE ACRE has moved in line with the HPI for terraced houses in the Swansea local authority area.
  • The May 2019 sale price of £325,000 represented a fair market value for the property.
  • The size, condition, and specification of 11 CASTLE ACRE has not materially changed since May 2019.
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.
