It's a bit of a vicious circle. Those that are buying both prove and disprove his point. He said most first home buyers want 4 bed two bath.... The fact that the average first home buyer is spending $310 - $350 on their house, kind of disproves this statement.
But those that are buying...
And what Joe is saying is the FHB is buying, on average, a house for $310,000. So either Barnett is wrong when he says most FHB are hanging out for the 4x2, or the numbers are wrong.
I think I'll go ahead and believe the numbers.
