It entirely depends on how your technical system is flagging opportunities.
There are a lot of people who are maintaining that while ever there is a decent spread of real estate yields over the risk free rate, they are good buying. Personally I don't buy that, it's overly simplistic. But it's a common opinion. There's also been some sell off on concerns about where property markets are in the cycle and the threat of Amazon to retailers.
But I would go back to my first point. How does your system flag opportunities?
