The problem with having a long string of successes in life is that you start to think you have the magic touch and anything you do will work out. So the bets get bigger and bigger and risk management is thrown out of the window. Eventually, your luck runs out.

Yet prices right now are not bargain basement. Not expensive, but hardly screaming bargains either. Try to rent a decent city centre apartment in Dublin for <1k euros.
