We are not moving away from this area until the end of this year, so we could move into the property after we are married (late May) and stay there until November and sell it after this. This would mean I would have lived there, but only for 6 - 7 months, would this help?
Mere occupation of a property does not necessarily amount to residence. It appears that you would live there temporarily, and always with the intention of moving out after a short period. On that basis private residence relief will not be available.
