15 CASTLE TERRACE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Northumberland local authority area over time, sourced from the HPI. The two 15 CASTLE TERRACE sales from June 2018 and November 2023 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 June 2018 sale was for 162% above the HPI. So the extrapolation line tracks at 162% above the HPI over time, until the November 2023 sale, where it rises to 260% above the HPI. The line then continues to track at 260% above the HPI.

What might 15 CASTLE TERRACE be worth now?

15 CASTLE TERRACE might now be worth an estimated £1,279,310.

This is based on house price inflation of 6.6%, between November 2023 and December 2024, for detached houses, in the Northumberland local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 6.6% inflationary increase is applied to the most recent sale price for 15 CASTLE TERRACE of £1,200,000 on 30th November 2023. For the value to have increased from £1,200,000 to £1,279,310 over the eleven months to December 2024, the following assumptions must hold true:

• The value of 15 CASTLE TERRACE has moved in line with the HPI for detached houses in the Northumberland local authority area.
• The November 2023 sale price of £1,200,000 represented a fair market value for the property.
