27 OBSERVATORY CLOSE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the South Oxfordshire local authority area over time, sourced from the HPI. The two 27 OBSERVATORY CLOSE sales from December 1999 and May 2005 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 December 1999 sale was for 21% above the HPI. So the extrapolation line tracks at 21% above the HPI over time, until the May 2005 sale, where it rises to 37% above the HPI. The line then continues to track at 37% above the HPI.

What might 27 OBSERVATORY CLOSE be worth now?

This is based on house price inflation of 107.7%, between May 2005 and April 2026, for terraced houses, in the South Oxfordshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 107.7% inflationary increase is applied to the most recent sale price for 27 OBSERVATORY CLOSE of £242,500 on 11th May 2005. For the value to have increased from £242,500 to £503,709 over the 21 years and one month to April 2026, the following assumptions must hold true:
