While it is true that it is a fool’s errand to try to time the property market, you can certainly buy at a dip. In fact, that is what you are supposed to do: Buy low and sell high.
It is very human in a down market to want to buy at the absolute lowest point. The problem, though, is that no one can identify the bottom until after the fact.
How many people have you met who regret not buying in 1998 or 2004 or 2008?
