18 OFFA is a very small semi-detached house of 58m², built sometime between 1967 and 1975, which could now be worth an estimated £176,294. It was last sold for £163,000 in September 2024, which was around 10% below the average September 2024 semi-detached price in the Wrexham local authority area. The most recent EPC inspection was May 2024, where the current energy rating was C, and the potential energy rating was B.
Land registry data shows two sales for 18 OFFA since 1st January 1995. The below table shows the price paid for the two sales, along with the average semi-detached price in the Wrexham local authority area for the corresponding sale date. Both of the two 18 OFFA 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 |
|---|---|---|---|
2024 20 SEP | £163,000 | £180,601 | 10% below HPI |
1999 19 APR | £40,000 | £45,041 | 11% below HPI |
The below graph shows the average semi-detached house price in the Wrexham local authority area over time, sourced from the HPI. The two 18 OFFA sales from April 1999 and September 2024 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 1999 sale was for 11% below the HPI. So the extrapolation line tracks at 11% below the HPI over time, until the September 2024 sale, where it rises to 10% below the HPI. The line then continues to track at 10% below the HPI.

18 OFFA might now be worth an estimated £176,294.
This is based on house price inflation of 8.2%, between September 2024 and April 2026, for semi-detached houses, in the Wrexham local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 8.2% inflationary increase is applied to the most recent sale price for 18 OFFA of £163,000 on 20th September 2024. For the value to have increased from £163,000 to £176,294 over the two years and five months to April 2026, the following assumptions must hold true:
