I would recommend you look for some good insurance and see how much umbrella insurance coverage you can buy with the $800 you'd use for LLC...It really seems that quite a bit of more beginner investors are very quick to start LLCs, it is not that difficult for a good lawyer to pierce through it. 

To answer that unique question would require research into local law on the subject of piercing the corporate veil.

In this case, it would be difficult for a court to pierce the corporate veil.Overall, not necessary unless you run/prove in court, a legitimate business where you can truly take benefit of the limited-liability aspect.

I will be buying a multi-family property somewhere in Western Washington (NOT Seattle and probably not Snohomish or Pierce Counties either) in Nov/Dec 2023.

He said Nevada was the state to setup a llc because they only have one way to pierce the veil and that is by fraud as opposed to Ohio where their are many different ways to do so.

It's called piercing the veil.

Key words: Airbnb, STR, Olympia, Washington, Thurston, VRBO, Tumwater, Pierce, Lewis, Bed and Breakfast

Kitsap County (where I am), Snohomish County, and Pierce County are worth looking at, though pay attention to the tax rates.

Yes, there is the limited liablity aspect, but even that can be somewhat dubious especially since newbies use it incorrectly and pierce their corporate veil. 

i don't think so, you only make the effort of creating an LLC if you're trying to protect your personal assets if you get sued, even still, a judge could pierce through the LLC and go after your asset if it's poor negligence or other reasons.
