Land registry data shows two sales for 12 COWLEAZE since 1st January 1995. The below table shows the price paid for the two sales, along with the average semi-detached price in the Monmouthshire local authority area for the corresponding sale date. Both of the two 12 COWLEAZE sales were for above the average price. The average price is sourced from the Office for National Statistics' House Price Index (HPI).

---|---|---|---|

The below graph shows the average semi-detached house price in the Monmouthshire local authority area over time, sourced from the HPI. The two 12 COWLEAZE sales from March 1995 and March 2004 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 March 1995 sale was for 31% above the HPI. So the extrapolation line tracks at 31% above the HPI over time, until the March 2004 sale, where it falls to 15% above the HPI. The line then continues to track at 15% above the HPI.
12 COWLEAZE might now be worth an estimated £340,081.
This is based on house price inflation of 126.8%, between March 2004 and March 2025, for semi-detached houses, in the Monmouthshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 126.8% inflationary increase is applied to the most recent sale price for 12 COWLEAZE of £149,950 on 19th March 2004. For the value to have increased from £149,950 to £340,081 over the 21 years to March 2025, the following assumptions must hold true:
