21 MARMADUKE STREET 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 21 MARMADUKE STREET sales from January 2007 and July 2011 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 2007 sale was for 2% above the HPI. So the extrapolation line tracks at 2% above the HPI over time, until the July 2011 sale, where it rises to 8% above the HPI. The line then continues to track at 8% above the HPI.

What might 21 MARMADUKE STREET be worth now?

This is based on house price inflation of 37%, between July 2011 and December 2024, 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 37% inflationary increase is applied to the most recent sale price for 21 MARMADUKE STREET of £185,000 on 15th July 2011. For the value to have increased from £185,000 to £253,468 over the twelve years and seven months to December 2024, the following assumptions must hold true:

• The value of 21 MARMADUKE STREET has moved in line with the HPI for detached houses in the County Durham local authority area.
• The July 2011 sale price of £185,000 represented a fair market value for the property.
