I am not talking about regional or mining towns, but as far as a major capital city as a whole or even a CBD suburb, what is the biggest median price drop you have ever seen ? Houses not units. The reason I ask is Perth. Where does the Perth decline rank in all of this, historically speaking ? Will it be similar or worse than the Bris floods or the Sydney decline after their previous boom ? Realistically we could see perth drop 10%, would anyone be brave enough to say we might see a 20% drop ?
