@Joshua Hughes -- Thank you for confirming you do have funds to cover your backside. I really misinterpreted the first post. I worked with (many) folks in a retail gig that had nothing in reserve, like $0. Scary.
I'm sure you listen to the podcasts and read the usual book collections. My ideas are digested from a bunch of theirs and my own business philosophy. Some say it's vital to keep any tenant deposits in a dedicated account (savings/CD ladder/FDIC-insured accessible thing) so commercial landlord accounting books reflect that this is a definitively separate non-fungible account from other spending accounts. If you have a financial advisor/accountant, maybe ask them if this practice is common (or required) for your area. It's on my checklist for my first BRRRR adventure.
And you mention your 'normal' checking account. In all of my businesses, I've found it very helpful to have completely separate banking accounts from my personal accounts. Easier bookkeeping, easier doing taxes, easier if there's an audit. I imagine that is what you meant. In a perfect world, we maximize efficiency and profit from every corner: rent checks go into business checking account for that house or that LLC (not one's personal acct). From there, whatever money is not needed for the next 2 or 3 months' worth of immediate bills funnels into better yielding free insured accounts. As you said, every dollar has a job. Your goal here is to fund the next investment, so that's your eye-on-the-prize. Optimizing that growing dowry/downpayment can be shifting all excess funds to a high-yield money market account, or a CD. Just not something that is harder to get at (I-bond) or can lose value unexpectedly such as stocks/bonds/crypto/gold. Every budget is different.

And you don't have to take any out as owner draws for your personal budget? Presumably there is a W-2 job for ones own income to personal bank accounts. Paying for the roof over head, feeding and clothing family, buying healthcare insurance (I like HSA plans for the investment opportunity), put gas in the non-work car, etc. all comes from somewhere. As would contributions to a Roth or SEP-IRA as a tool for your wealth building. Presumably a fraction from a W-2 gig goes into a 401k/403/TSA plan. But that is all on the personal ledger, not the real estate empire ledgers.
