I wouldn't worry, there's never been a serious house price crash in the absence of a recession, and our economy is pretty strong at the moment. A slight 'correction' may be on the cards but i suggest this will be in the region of 5-10% max and will only effect those who overpaid in the last year or so. Other than that I wouldn't worry, and with interest rates predicted to start coming down early next year it's all good. We have a strong economy here and with high demand for property and a real shortage there's no way house prices can drop any real amount in my opinion.
