I would use a PA entity for the PA business.

I plan on using a property management company in order to keep the property in order until I move (eventually I want to bring property managers under my own business entity to focus only on my properties). 

If you want to vest under an entity though you may be out of luck going that route.

Or could another broker at my company list and get paid commission so long as the company doesn't retain any profits and just acts as a pass-through entity to pay the other broker? 

I always call the booking entity first (Airbnb, VRBO etc) and ask them how they would like to handle it.

What I am unsure about is if the whole 60-40 rule around payroll deduction vs owner distributions within an S-Corp can still apply in this situation if the filing entity will only be the S-Corp but the payments are made out of LLC #1, the disregarded entity owned wholly by the S-Corp.

This snippet is from their article here.If an investor-owner is a legal entity (LLC, S-Corp) does that preclude the investor from having a junior accessory dwelling unit (JADU)?

That triggered us having to pay transfer taxes, as the state treats an LLC as a disregarded entity, even if it contains the same members.Most of our clients invest using an LLC as their preferred corporate structure.

For those of you who are familiar with how to open an entity in your state, how to stay self motivated, how to make effective phone calls, and just operate in a professional manner, the first half of the training may seem slow/repetitive.

For tax purposes its a passthrough entity, but it makes it a lot cleaner to do tax strategies around maximizing expenses to lower taxable income.
