12 OFFA is a very small extended semi-detached house of 71m², built sometime between 1967 and 1975, which could now be worth an estimated £194,893. It was last sold for £125,000 in July 2015, which was about the average July 2015 semi-detached price in the Wrexham local authority area. The most recent EPC inspection was July 2015, where the current energy rating was D, and the potential energy rating was B.
Land registry data shows two sales for 12 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. One of the two 12 OFFA sales was roughly equal to the average price, whilst the other was 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 |
|---|---|---|---|
2015 23 JUL | £125,000 | £125,280 | Close to HPI |
2006 12 APR | £115,000 | £121,161 | 5% 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 12 OFFA sales from April 2006 and July 2015 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 2006 sale was for 5% below the HPI. So the extrapolation line tracks at 5% below the HPI over time, until the July 2015 sale, where it rises to roughly the same level as the HPI. The line then continues to track in line with the HPI.

12 OFFA might now be worth an estimated £194,893.
This is based on house price inflation of 55.9%, between July 2015 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 55.9% inflationary increase is applied to the most recent sale price for 12 OFFA of £125,000 on 23rd July 2015. For the value to have increased from £125,000 to £194,893 over the eleven years and three months to April 2026, the following assumptions must hold true:
