Are you buying an investment or a home? A house can be either.
If you're buying a place to live that you expect to appreciate and create net wealth, you're making an investment. From an investment point of view, it may make sense to wait.
If you're buying a home, does it matter what the FMV for it is for the next 10 years? If you never sell the property you never "realize" the loss. It goes up, it goes down, it doesn't really matter. You've locked in a 30 year mortgage at almost no interest, secured a place to live at a relatively fixed cost, and provided a stable atmosphere to begin making memories that turn a house into a home. If you're looking for that there's no time like the present.
Frankly, market timing is darn near impossible. To say prices are peaking or a recession is looming is silly. If they were that easy to predict #1 they wouldn't happen (interventions would prevent them) and #2 there'd be a LOT more rich people as billions would be available for those that could market time.
