I totally agree with this. Do you really want to be signing contracts without pest and building inspections? You may need to wait until demand (probably not price) has cooled or alter your expectations a little.
Or you need to get out and walk around and see if you feel comfortable. Ask re agents where the housing commission is. At the end of the day, if you feel comfortable, it should be fine. Everywhere in Sydney will soon be gentrified!
There are all sorts of reports from all sorts of people - some who live in fantasy land and think they're top of the line classy because they're living in suburb A and not suburb B. Poppycock. Delusion. Unrealistic.
What do you think? If you're the one moving into that area, you're one of the people who will lead to it's gentrification.
650k will get you a good unit in a good suburb. Or a nice little house a bit further out. Have you looked around Granville, Merrylands area?
