Quote from @Melanie Baldridge: Newton's law of tax: What goes down must come up.Everyone enjoys the sweet benefits of bonus depreciation, but what happens when you sell?

I imagine a lot split would also significantly increase cost of utilities as now I would have 3 hookups in that scenario.I am also concerned what would happen to that sweet 3.25% 30 year fixed mortgage I have, which I don't want to create any risk over in the slightest.Any advice on how to frame my counter arguments would be incredibly appreciated.

If you have trouble managing 1 tenant that renews once a year changing tenants every 30 days will add a lot of complexity to it for you

Whoever taught you that I would go to them and do what they did as this setup for an ownership structure in my opinion is far to complex and your CPA is going to be scratching there head at end of year with all the tax stuff they will have to do and how you have to keep bank accounts for each entity and move money form one to the other to the other....

They have no profit motive so they will take their sweet, sweet time in installing any locks you need.

Quote from @Eric Prescott: Yes, I understand that appreciation often means less cash flow and good cash flow typically means weaker appreciation, but there is a sweet spot where there is decent appreciation and sufficient cash flow to cover expenses so that the property pays for itself, and that is what I'm honing in on. 

You can definitely integrate Zelle/Venmo into your systems but there's easier ways. 100% agree with this explanation BUT I think there is a sweet spot not mentioned. 

Separate LLC per Property: Maximizes liability protection but adds complexity and costs with individual tax filings.3.

Personally I am looking to grow in RE and buy a 2nd home in LA/SD and eventually buy a multifamily complex.

On large complexes you can look up their website and see if they have a leasing map that identifies address/unit.
