Real estate is basically an auction market much like the stock market. There are bids and asks in real estate just like the stock market. Unfortunately, you cannot access the real estate sales information in real time. You cant see the bids and asks.
What is rule one of an auction market? Rule one is that nothing is traded at random. Prices can be charted and patterns do form. Those candlestick charts have been in use for hundreds of years starting with the trading of rice.
There is some data we can plot on a chart for housing, however, and from what we can see on the chart the trend is down.
The trend is your friend. . .If the trend is down, then it may continue downward. WHere the bottom is at. . .no one knows.
