Land registry data shows two sales for 3 THE WARREN since 1st January 1995. The below table shows the price paid for the two sales, along with the average detached price in the Hertsmere local authority area for the corresponding sale date. Both of the two 3 THE WARREN sales were for above the average price. The average price is sourced from the Office for National Statistics' House Price Index (HPI).
| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|
2014 27 MAR | £3,240,000 | £762,125 | 325% above HPI |
2004 29 APR | £2,300,000 | £524,162 | 339% above HPI |
The below graph shows the average detached house price in the Hertsmere local authority area over time, sourced from the HPI. The two 3 THE WARREN sales from April 2004 and March 2014 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 April 2004 sale was for 339% above the HPI. So the extrapolation line tracks at 339% above the HPI over time, until the March 2014 sale, where it falls to 325% above the HPI. The line then continues to track at 325% above the HPI.

3 THE WARREN might now be worth an estimated £5,157,812.
This is based on house price inflation of 59.2%, between March 2014 and May 2026, for detached houses, in the Hertsmere local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 59.2% inflationary increase is applied to the most recent sale price for 3 THE WARREN of £3,240,000 on 27th March 2014. For the value to have increased from £3,240,000 to £5,157,812 over the eleven years and ten months to May 2026, the following assumptions must hold true:
