I own properties in Colorado and Central Iowa, I haven't lost money in Iowa, but at lot more mistakes can be made when we are going for 4-8% appreciation in Colorado than trying to defend 50-100 per door in central Iowa. 

The reason is that filing 1099s can be an important factor if you have to defend treating your rental business as a true "trade or business," in the IRS definition.

#1 person to ask is your CPA...as they are going to have to help defend you on whatever actions you take.My guess is you cannot do what you want to do, and actually all this probably would hurt you if you could do it in the long run.I would think there are rules about self dealing that would prohibit this.The second concern I can think of is capital gains taxes....so the LLC would have to recapture the depreciation when you sell it and pay capital gains taxes on the profit....vs if it is your personal home, chances are you will have no capital gains.Nice way of creative thinking, but I think if it were this easy to make big profits, everyone would be doing it.   

Having a LLC doesn’t eliminate the need for the insurnace — you need their lawyers anyway to defend against the lawsuit otherwise you’ll go broke protecting the assets in the LLC...So, while the LLC is there to provide a legal limited liability separation, it comes at a cost (in many ways significant) and it may not be worth it.

As this happens, the US will be forced to raise interest rates to defend the currency, which might sink the real estate market and economy way more than during the last crisis.4.

Not defending the 90/10 split either, because I've never seen it before.

I understand that the quality of the report could be higher or they have more experience defending successfully against IRS audits, etc. but am I missing anything else regarding total depreciation calculated?

Look all, everyone has an opinion and you can always defend and justify your opinions but that doesn't make it the right thing to do.

You are defending a strategy for the SAKE of defending THAT strategy.
