VC,
Throughout the time someone owns a home the price constantly changes but only two prices matter. The price you pay and the price you sell for. You will always be making decisions at a snapshot in time with limited information. If you decide to buy the house, get on with enjoying your life and stay away from places like this. If you decide to wait, this is a fine place to come for information as long as you understand what it is. A place full of people with negative views on housing.
Either way, if you can afford and buy it you should do your best to enjoy it.
