HYDOWNE is a very large extended detached house of 169m², built sometime between 1950 and 1966, which could now be worth an estimated £699,672. It was last sold for £705,000 in June 2025, which was around 21% above the average June 2025 detached price in the Maldon local authority area. The most recent EPC inspection was March 2025, where the current energy rating was C, and the potential energy rating was B.
Land registry data shows two sales for HYDOWNE since 1st January 1995. The below table shows the price paid for the two sales, along with the average detached price in the Maldon local authority area for the corresponding sale date. Both of the two HYDOWNE 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 |
|---|---|---|---|
2025 30 JUN | £705,000 | £580,771 | 21% above HPI |
1996 18 OCT | £119,000 | £98,468 | 21% above HPI |
The below graph shows the average detached house price in the Maldon local authority area over time, sourced from the HPI. The two HYDOWNE sales from October 1996 and June 2025 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 October 1996 sale was for 21% above the HPI. So the extrapolation line tracks at 21% above the HPI over time, until the June 2025 sale, which was also at 21% above the HPI.

HYDOWNE might now be worth an estimated £699,672.
This is based on house price deflation of 0.8%, between June 2025 and July 2025, for detached houses, in the Maldon local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 0.8% deflationary decrease is applied to the most recent sale price for HYDOWNE of £705,000 on 30th June 2025. For the value to have decreased from £705,000 to £699,672 over the eleven months to July 2025, the following assumptions must hold true:
