Property as a whole is a consistently well performing asset, particularly in the long term.
It’s possible a stock market crash could cause a recession and a dip in property prices. But then usually that’s followed by a drop in the building of new homes, which usually ends up causing prices to stabilise, if not to start rising again when the market starts to get squeezed by the lack of new supply.
So if you wait you might be able to get a bargain. Might. But individual properties are heterogeneous - presumably this is one you actually want, and what you get a bargain on might not be to the same degree.
Ultimately I think the main things to consider are, (a) can you afford this as is?, (b) is your employment secure in the event of any downturns?, and © if the market does crash, would you be happy to live there in the medium term until it improves?
