I'm not telling you how to spend your money
Just that House and land for near $1m in this area can never be changed by the fact your still in Blacktown council and near by areas.
Blacktown council means nothing these days, it's one of the fastest growing areas in Australia and it's becoming a big area for young professionals. With the "Australian Silicon Valley" going to be developed out at Badgery's Creek very shortly and Blacktown's plan to become the next regional city, "the fact you're still in Blacktown Council" is no big drama. I'm moving out of The Hills council to be in Blacktown council, shock horror.
As for Stonecutter's Ridge, it's not any golf course, it's a Greg Norman golf course. Hard to say how much that will really impact on price but time will tell.
