COSY NEST Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Test Valley local authority area over time, sourced from the HPI. The two COSY NEST sales from June 1998 and May 1999 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 1998 sale was for 3% above the HPI. So the extrapolation line tracks at 3% above the HPI over time, until the May 1999 sale, where it rises to 14% above the HPI. The line then continues to track at 14% above the HPI.

What might COSY NEST be worth now?

COSY NEST might now be worth an estimated £419,899.

This is based on house price inflation of 322%, between May 1999 and December 2024, for semi-detached houses, in the Test Valley local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 322% inflationary increase is applied to the most recent sale price for COSY NEST of £99,500 on 10th May 1999. For the value to have increased from £99,500 to £419,899 over the 24 years and five months to December 2024, the following assumptions must hold true:

• The value of COSY NEST has moved in line with the HPI for semi-detached houses in the Test Valley local authority area.
• The May 1999 sale price of £99,500 represented a fair market value for the property.
• The size, condition, and specification of COSY NEST has not materially changed since May 1999.
