I am currently pursuing my broker's license and training to become a property manager to simplify owners' lives. 

(app wouldn’t let me scroll)...To try to simplify the cash flow, you could create a separate “mgt LLC” that has an agreement with “property LLC” that just holds Title.

In some cases you can actually make a  profit  from real estate rentals and yet take a loss on your tax return due to the "Depreciation" This is the basics simplified.

Everything I read seems to emphasize making sure to accurately and completely estimate your costs up front to make sure you're dealing with a good investment, but so many people's estimates seem to simplify the costs to only recurring monthly and highly predicatable costs like taxes and utilities....etc. 

But for deals that are "basic" (I could just be over simplifying this) should I just keep hoping to find a HML that will give me a chance and keep networking and hope I find a PML or is there something else I can focus my efforts own?

Keep records for everything, it will simplify your life in the long run. ie, keep mileage logs, keep all receipts for all real estate related purchases, etc.Regarding "active participation" I think the above poster was confused on that when he referred to 50% of your time.

I read that very early on and it really simplifies a lot of the concepts and approaches, and shows how “easy” it is to slowly become a real estate millionaire by buying sfh’s one at a time!

You may consider using it in the future as it is attorney reviewed and may simplify the process for you.

It could simplify some filing requirements to have the LLC there and depending on state laws, there could be other advantages too, but that's about it as far as I know.3) If you really want to maximize depreciation, consider a reno job or a BRRRR.

that’s a VERY overly-simplified process of what takes place while buying/selling multi-family properties.
