17 WESTBOURNE PLACE 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 three 17 WESTBOURNE PLACE sales between November 2002 and September 2017 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 June 2006 sale was for 139% above the HPI. So the extrapolation line tracks at 139% above the HPI over time, until the September 2017 sale, where it rises to 184% above the HPI. The line then continues to track at 184% above the HPI.

What might 17 WESTBOURNE PLACE be worth now?

17 WESTBOURNE PLACE might now be worth an estimated £480,071.

This is based on house price inflation of 50.5%, between September 2017 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 50.5% inflationary increase is applied to the most recent sale price for 17 WESTBOURNE PLACE of £319,000 on 22nd September 2017. For the value to have increased from £319,000 to £480,071 over the nine years and five months to April 2026, the following assumptions must hold true:

  • The value of 17 WESTBOURNE PLACE has moved in line with the HPI for terraced houses in the Swansea local authority area.
  • The September 2017 sale price of £319,000 represented a fair market value for the property.
  • The size, condition, and specification of 17 WESTBOURNE PLACE has not materially changed since September 2017.
