27 ALLERGATE 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 27 ALLERGATE sales from January 1995 and June 2000 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 January 1995 sale was for 1% below the HPI. So the extrapolation line tracks at 1% below the HPI over time, until the June 2000 sale, where it rises to 53% above the HPI. The line then continues to track at 53% above the HPI.

What might 27 ALLERGATE be worth now?

27 ALLERGATE might now be worth an estimated £364,778.

This is based on house price inflation of 191.8%, between June 2000 and April 2026, 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 191.8% inflationary increase is applied to the most recent sale price for 27 ALLERGATE of £125,000 on 9th June 2000. For the value to have increased from £125,000 to £364,778 over the 26 years and two months to April 2026, the following assumptions must hold true:

• The value of 27 ALLERGATE has moved in line with the HPI for detached houses in the County Durham local authority area.
• The June 2000 sale price of £125,000 represented a fair market value for the property.
