no-one expected the crash in 2007/8
Not sure about Bristol but in London the 2008 “crash” consisted of prices dropping by up to 15% at most, then two years later completely recovered and heading up ever since (source).
Not much of a crash, and as long as you weren’t planning to move for two years you were laughing even if you bought at the height of the peak before the crash.
My opinion is that if you are looking to buy in a desirable area then it is always better to buy sooner rather than later.
