Have a look at places where this has happened eg: Japan. RE dead / declining.
IR at emergency lows for 10 years...??? don't bet a house on it.
These low IRs are a death trap. Thats what deters me the most, cos I know if they stay this low or lower, then its because RE / economy is dead in the water. OR if they return to norm or higher, then mortgaged people are screwed.
