Land registry data shows two sales for 4 WINDSOR ROAD since 1st January 1995. The below table shows the price paid for the two sales, along with the average semi-detached price in the Harrow local authority area for the corresponding sale date. Both of the two 4 WINDSOR ROAD sales were for below 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 |
|---|---|---|---|
1998 23 JAN | £112,000 | £128,627 | 13% below HPI |

The below graph shows the average semi-detached house price in the Harrow local authority area over time, sourced from the HPI. The two 4 WINDSOR ROAD sales from May 1996 and January 1998 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 May 1996 sale was for 14% below the HPI. So the extrapolation line tracks at 14% below the HPI over time, until the January 1998 sale, where it rises to 13% below the HPI. The line then continues to track at 13% below the HPI.

4 WINDSOR ROAD might now be worth an estimated £577,472.
This is based on house price inflation of 415.6%, between January 1998 and April 2026, for semi-detached houses, in the Harrow local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 415.6% inflationary increase is applied to the most recent sale price for 4 WINDSOR ROAD of £112,000 on 23rd January 1998. For the value to have increased from £112,000 to £577,472 over the 27 years and nine months to April 2026, the following assumptions must hold true:
