My understanding is that the smart way to sell real estate in California is to simply not sell it, and rather to sell control of the company that owns the real estate.
There are non-tax benefits, such as bypassing probate, but as the value of a property increases the 1% property tax becomes increasingly worrying. I suspect this is part of the reason why it's more common with commercial real estate.
The goal is to avoid tax reassessment when a property is sold, which is a big deal since the average price of a house in CA in 1940 was $36,700 and is now $211,500 (and much, much higher in places like Los Angeles and San Francisco). Even at the average house price, it's the difference between a $367/yr bill versus a $2,115/yr bill. Presumably commercial real estate has seen an equivalent rise over time.
