15 ALLERGATE 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 two 15 ALLERGATE sales from January 2000 and March 2026 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 2000 sale was for 405% above the HPI. So the extrapolation line tracks at 405% above the HPI over time, until the March 2026 sale, where it falls to 190% above the HPI. The line then continues to track at 190% above the HPI.

What might 15 ALLERGATE be worth now?

15 ALLERGATE might now be worth an estimated £332,431.

This is based on house price inflation of 2.3%, between March 2026 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 2.3% inflationary increase is applied to the most recent sale price for 15 ALLERGATE of £325,000 on 31st March 2026. For the value to have increased from £325,000 to £332,431 over the eleven months to April 2026, the following assumptions must hold true:

• The value of 15 ALLERGATE has moved in line with the HPI for terraced houses in the County Durham local authority area.
• The March 2026 sale price of £325,000 represented a fair market value for the property.
• The size, condition, and specification of 15 ALLERGATE has not materially changed since March 2026.
