If you're buying a home to live in, the answer is probably: not a lot. It's very hard to time the market and if you hold out for a market drop, or a drop that you deem big enough, you might find that you leave it too long and miss your chance. If you hold off selling, expecting things to pick up soon, you might find they don't and you're stuck facing a worse proposition.
When you buy and sell in the same market, how it's moving doesn't mean a lot — so you can probably carry on no matter what prices are doing. If you're a first-home buyer, you are most likely making a long-term decision that will see you ride out several property upswings and downturns.
Whether you can pay your mortgage comfortably will be a more important decision than whether prices might drop 5 per cent in the next few months.
Understand why you're making the property decisions you're considering and how they fit into your long-term plan. Then stay the course — with every downturn, there's always a recovery coming on the other side.
