Why shouldn’t I just sell all my investment properties and throw it into stocks?

Seems like the major consensus is that stocks is a much better investment than RE because of the historical annual return and also less headaches to deal with compared to what you have to do with houses (maintenance, hoa if applies, prop management, sudden things that can happen at any time (flood, squatters, tax increase, etc).

If that’s the case then why even bother buying investment properties then? Currently I own 4 homes. 3 are used as vacation rentals with low interest rates at 2.85%, 3.3% and 3.5%. I have one primary home at 6.68% that we live in.

Is there a good reason why I shouldn’t just outright sell all three investment properties and just buy and hold etfs? Am I missing something here?
