JANUS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cherwell local authority area over time, sourced from the HPI. The two JANUS sales from September 2005 and March 2021 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 September 2005 sale roughly matched the HPI. So the extrapolation line tracks roughly in line with the HPI over time, until the March 2021 sale, where it rises to 14% above the HPI. The line then continues to track at 14% above the HPI.

What might JANUS be worth now?

JANUS might now be worth an estimated £650,516.

This is based on house price inflation of 18.6%, between March 2021 and February 2025, for 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 18.6% inflationary increase is applied to the most recent sale price for JANUS of £548,650 on 16th March 2021. For the value to have increased from £548,650 to £650,516 over the four years and one month to February 2025, the following assumptions must hold true:

• The value of JANUS has moved in line with the HPI for detached houses in the Cherwell local authority area.
• The March 2021 sale price of £548,650 represented a fair market value for the property.
• The size, condition, and specification of JANUS has not materially changed since March 2021.
