20 GLAISDALE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the County Durham local authority area over time, sourced from the HPI. The two 20 GLAISDALE sales from September 1998 and September 2007 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 September 1998 sale was for 34% above the HPI. So the extrapolation line tracks at 34% above the HPI over time, until the September 2007 sale, where it falls to 21% above the HPI. The line then continues to track at 21% above the HPI.

What might 20 GLAISDALE be worth now?

20 GLAISDALE might now be worth an estimated £163,924.

This is based on house price inflation of 17.1%, between September 2007 and December 2024, for semi-detached 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 17.1% inflationary increase is applied to the most recent sale price for 20 GLAISDALE of £140,000 on 6th September 2007. For the value to have increased from £140,000 to £163,924 over the sixteen years and nine months to December 2024, the following assumptions must hold true:

• The value of 20 GLAISDALE has moved in line with the HPI for semi-detached houses in the County Durham local authority area.
• The September 2007 sale price of £140,000 represented a fair market value for the property.
• The size, condition, and specification of 20 GLAISDALE has not materially changed since September 2007.
