There are conditions that must be met.Also, I believe the taxes are higher in Richland County than Lexington County, but I don't like there, so I don't have personal experience with that.

So I wonder if I can sell my home in Idaho, purchase the new one under my personal name, then how many months or years must pass before I can setup an LLC as the owner of my primary residence, or if you think that will be a good idea? 

A new person moves in and she says the upstairs neighbors are creating a ton of noise.

Even when I did reach them the first time,  the other person on the other line sounds like a moron who doesn't know how to help. 

The question is, what is the intention  of the owner, not what would a reasonable person think is the intention of the owner.

I used $80k to pay off personal debts and $50k to remodel it by myself with my two hands.

I personally would revisit your strategy of buying a negative cash flow property in SoCal, right now.
