ROSEMARY COTTAGE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the St Albans local authority area over time, sourced from the HPI. The three ROSEMARY COTTAGE sales between September 1996 and January 2013 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 July 1999 sale was for 25% above the HPI. So the extrapolation line tracks at 25% above the HPI over time, until the January 2013 sale, where it rises to 26% above the HPI. The line then continues to track at 26% above the HPI.

What might ROSEMARY COTTAGE be worth now?

ROSEMARY COTTAGE might now be worth an estimated £947,336.

This is based on house price inflation of 75.4%, between January 2013 and February 2025, for semi-detached houses, in the St Albans local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 75.4% inflationary increase is applied to the most recent sale price for ROSEMARY COTTAGE of £540,000 on 14th January 2013. For the value to have increased from £540,000 to £947,336 over the eleven years and eleven months to February 2025, the following assumptions must hold true:

• The value of ROSEMARY COTTAGE has moved in line with the HPI for semi-detached houses in the St Albans local authority area.
• The January 2013 sale price of £540,000 represented a fair market value for the property.
• The size, condition, and specification of ROSEMARY COTTAGE has not materially changed since January 2013.
