It was last sold for £189,000 in February 1999, which was around 156% above the average February 1999 detached price in the Wrexham local authority area.

Land registry data shows two sales for SWALLOW BARN since 1st January 1995. The below table shows the price paid for the two sales, along with the average detached price in the Wrexham local authority area for the corresponding sale date. One of the two SWALLOW BARN sales was for above 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 |
|---|---|---|---|
1999 19 FEB | £189,000 | £73,824 | 156% above HPI |
1997 24 MAR | £60,000 | £68,913 | 13% below HPI |
The below graph shows the average detached house price in the Wrexham local authority area over time, sourced from the HPI. The two SWALLOW BARN sales from March 1997 and February 1999 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 March 1997 sale was for 13% below the HPI. So the extrapolation line tracks at 13% below the HPI over time, until the February 1999 sale, where it rises to 156% above the HPI. The line then continues to track at 156% above the HPI.

SWALLOW BARN might now be worth an estimated £799,707.
This is based on house price inflation of 323.1%, between February 1999 and April 2026, for 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 323.1% inflationary increase is applied to the most recent sale price for SWALLOW BARN of £189,000 on 19th February 1999. For the value to have increased from £189,000 to £799,707 over the 26 years and ten months to April 2026, the following assumptions must hold true:
