"Recent house price appreciation has been driven by more than simply a strongly growing population. Low interest rates have encouraged domestic investors to allocate assets into housing. Foreign investors have also been buying. A reduced rental return on housing would eventually discourage domestic investors but probably comes with a lag.
The apparent equalisation between an undersupply of housing versus strong demand for dwellings in major metropolitan areas comes as the official cash rate remains at a record low of 2.5%, and as the major banks lower their fixed rate home loans in an attempt to entire more people to borrow more."
This article applies more to the Sydney and Melbourne markets than Brisbane. It is important to look at individual markets, and not take southern trends and blindly apply them to Brisbane.
