The big problem is finding a decent rental in Perth. On the other hand, a lot of indicators are pointing to a slowdown in the mining boom so that will have an obvious impact on housing demand, both rental and purchase.I've rented for two years and I'm thinking of buying. However, I work in property so get exposure to all the stats and sentiment from housing market (Housing insiders always tell you its a great time to buy no matter what the market conditions are but privately they are worried). From what I can gather, there's further correction on the horizon. Not talking significant falls, just stagnating or declining prices. I'm only going to proceed in buying if I think its a good deal.Good luck whatever you decide
