Congrats on working hard in this adventure. The groundwork will help you learn and see what you like/don't like in the future.
The answer lies in "how big" and "how fast". Just the other day I was speaking to a client and they went "big" on the asset protection layers and it was a bit expensive and a bit to early for them. All they had was a 10-unit and a 4-unit. As a result, the funds that were rolling for today it was better to have a simple LLC, umbrella insurance policy, and proper business/landlord insurance added on. The cost, risk, and keeping up is a good balance for a while. The next steps could be to consider just adding LLC for a few properties at a time.
Another concept is will you max out on SFH? Will you go into syndications? Will you jump to commercial? Will you stay self-managing or not? Those also impact possible ideas of where to go next as well.
Now, if you are shooting for the moon for multiple trusts and family offices around the empire, well, that a whole new conversation of doing steps as you grow.
I hope this helps with painting some pictures for you.
