advice

I'm am a first home buyer looking to get into the north brisbane area. being looking for about two weeks for my family home. price range around 400 to 450. there seems a shortage in supply, while a strong demand around these prices. everyone say it's the first home buyer (like me). now if the gov stops the 14 to 21 grant this july does that mean demand will drop and supply increase, therefore, a drop in prices. then there is all the unemployment that is happening?? The advise i need. do anyone think that house prices will drop futher in the north brisbane area. im moving from the sunshine coast and trying to decide to either buy or rent for a futher 6 months.

cheers
