12 DUMAS CLOSE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Cherwell local authority area over time, sourced from the HPI. The two 12 DUMAS CLOSE sales from March 2011 and September 2017 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 March 2011 sale was for 15% below the HPI. So the extrapolation line tracks at 15% below the HPI over time, until the September 2017 sale, where it rises to 8% above the HPI. The line then continues to track at 8% above the HPI.

What might 12 DUMAS CLOSE be worth now?

12 DUMAS CLOSE might now be worth an estimated £387,461.

This is based on house price inflation of 25%, between September 2017 and May 2026, for semi-detached houses, in the Cherwell local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 25% inflationary increase is applied to the most recent sale price for 12 DUMAS CLOSE of £310,000 on 15th September 2017. For the value to have increased from £310,000 to £387,461 over the nine years and four months to May 2026, the following assumptions must hold true:

  • The value of 12 DUMAS CLOSE has moved in line with the HPI for semi-detached houses in the Cherwell local authority area.
  • The September 2017 sale price of £310,000 represented a fair market value for the property.
  • The size, condition, and specification of 12 DUMAS CLOSE has not materially changed since September 2017.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
