23 CRAGSIDE Price Paid vs. HPI Average

The below graph shows the average detached house price in the County Durham local authority area over time, sourced from the HPI. The two 23 CRAGSIDE sales from September 1995 and May 1999 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 1995 sale was for 68% above the HPI. So the extrapolation line tracks at 68% above the HPI over time, until the May 1999 sale, where it falls to 36% above the HPI. The line then continues to track at 36% above the HPI.

What might 23 CRAGSIDE be worth now?

23 CRAGSIDE might now be worth an estimated £328,670.

This is based on house price inflation of 225.4%, between May 1999 and July 2025, for 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 225.4% inflationary increase is applied to the most recent sale price for 23 CRAGSIDE of £101,000 on 21st May 1999. For the value to have increased from £101,000 to £328,670 over the 25 years and ten months to July 2025, the following assumptions must hold true:

• The value of 23 CRAGSIDE has moved in line with the HPI for detached houses in the County Durham local authority area.
• The May 1999 sale price of £101,000 represented a fair market value for the property.
• The size, condition, and specification of 23 CRAGSIDE has not materially changed since May 1999.
