21 CAISTER CLOSE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the County Durham local authority area over time, sourced from the HPI. The three 21 CAISTER CLOSE sales between June 2007 and October 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 May 2012 sale was for 126% above the HPI. So the extrapolation line tracks at 126% above the HPI over time, until the October 2020 sale, where it rises to 164% above the HPI. The line then continues to track at 164% above the HPI.

What might 21 CAISTER CLOSE be worth now?

21 CAISTER CLOSE might now be worth an estimated £302,504.

This is based on house price inflation of 37.5%, between October 2020 and April 2026, for terraced houses, in the County Durham local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 37.5% inflationary increase is applied to the most recent sale price for 21 CAISTER CLOSE of £220,000 on 30th October 2020. For the value to have increased from £220,000 to £302,504 over the six years and six months to April 2026, the following assumptions must hold true:

  • The value of 21 CAISTER CLOSE has moved in line with the HPI for terraced houses in the County Durham local authority area.
  • The October 2020 sale price of £220,000 represented a fair market value for the property.
  • The size, condition, and specification of 21 CAISTER CLOSE has not materially changed since October 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.
