By this time, I became so hungry for learning real estate investing.

The amount of digital ink that is spilled on this site about LLC's and how to set up complex structures  by folks who can hardly be called investors is a bit maddening to me as it keeps folks from actually investing dues paralysis by analysis due to things that really do not mater a great deal.

My question is how can I access my ADU and Boat without having to contact the tenant. 

My primary goals are to use BRRR to buy-and-hold these 2-3 unit, and multifamily properties.I hope this context helps!

Or do you also do this to HML at the very beginning?

Thanks for your help!

Hey Sean, a lot of investors are experiencing this same problem.

This will be dependent on the bank.

This is a great place to ask questions about projects, scenarios, or get advice on areas that you aren't as familiar with.
