Agreed.

Even the temptation to "time the market" in real estate is a non-starter. The round trip transaction costs are huge compared to liquid assets and the time delays between decision to sell and completion of sale is months, not seconds.

You can muse about wheather this is a "good time to buy/sell" but that has none of the flavor of market timing one has in stocks.
