Wow, I am impressed. You’ve just proven that real estate cycles can be predicted. Good stuff!
Let’s remember that median prices lag by 2 years, so in reality your model is only lagging by 1 year on the way up. This would be one more indicator that we can use to confirm the top or trough.
I recall prior posts where we discussed whether real estate cycles can be predicted, and some people insisted that real estate troughs cannot be predicted, since there would be false bounces/rallies.
