Land registry data shows two sales for BIRKBY since 1st January 1995. The below table shows the price paid for the two sales, along with the average detached price in the Test Valley local authority area for the corresponding sale date.

The average price is sourced from the Office for National Statistics' House Price Index (HPI).

The below graph shows the average detached house price in the Test Valley local authority area over time, sourced from the HPI. The two BIRKBY sales from December 1998 and November 2007 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 1998 sale was for 6% below the HPI. So the extrapolation line tracks at 6% below the HPI over time, until the November 2007 sale, where it rises to 12% above the HPI. The line then continues to track at 12% above the HPI.
BIRKBY might now be worth an estimated £683,608.
This is based on house price inflation of 59%, between November 2007 and December 2024, for 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 59% inflationary increase is applied to the most recent sale price for BIRKBY of £430,000 on 27th November 2007. For the value to have increased from £430,000 to £683,608 over the sixteen years and eleven months to December 2024, the following assumptions must hold true:
