I think quite a few people, (including that lady from CB Ellis) are in for a shock.
The only long term study on real estate price growth in real terms that I'm aware of was undertaken in Holland. The study examined property prices in Amsterdam over a 300 year period, the average annual rise in prices in the period, 0.3%.
People discuss the Irish property market as if the Irish economy was a self sufficient entity removed from the vagaries of cyclical economic growth and contraction. In fact Ireland is almost uniquely exposed to a global contraction in trade.
If any one is interested in what lies in store for the Irish property market/economy (the same thing essentially) then look no further than the US. You know the nation that drags us along on its economic coat tails; its one year further down the debt bubble correction trail than us.
Edit
Have a butchers at this, not a Goldilocks perspective I'm afraid.
