I would only add you really need to think about your commute everyday if you are working anywhere past Rowley Rd freeway exit. We moved in 2013 rented in Cockburn as close to family, kids in good school there when we bought a house in Baldivis March 2014. I worked in Willetton OH works all over in construction industry but a lot in the city. Spoke to someone else living there ' Oh yes its great only 20 mins on the freeway' LIES!!! It takes at least 40 mins from Baldivis Saftey Bay Rd Exit to Russell Rd on any weekday when you leave at 7.15 a.m without factoring in any accidents or roadworks.
I liked Baldivis as a suburb we had a lovely 4x2 with pool, if everything you do is in that area....work, school, after school activities, social lives ( both yours and kids, that I didnt factor in).
Have now sold the house at a 40k loss ( price and fees) and currently renting in Hammond Park , trying to recoup some of the money we lost.
If you want any more info feel free to PM me. Love living in Perth just not so far down the freeway!! :)
