I've been looking at both Pierce and Thurston counties. 

This means that you will probably need to pay registration and filing fees in at least 2 states if you don’t buy CA property as a CA resident.Any lawsuits should be limited to the assets of the LLC and not your personal assets (assuming you run the LLC appropriately and the corporate veil is not pierced, some debate as to SMLLC).

@David Pierce The Navy base is in Everett. 

They can't touch RE King without piercing the veil. 

Is transferring money from this business account into your personal account considering 'piercing the corporate veil?'

(CommercialLikely requires own llc)You’re probably talking about piercing the veil.  

was told that a two member LLC is more favorable for flipping activities for two reasons: 
1) much less likely to be audited vs a single member llc 2) much more difficult to pierce the corporate veil compared to a single member (many cases recently have not honored single member Llc's in terms of protecting and separating personal assets from company assets).

The easiest thing to do would be to have one bank account and run everything through there but apparently that would pierce the corporate veil.

Will depend on several factors like the type of property, type of tenants, your risk tolerance, other assets you own, your estate planning, laws where the property is located, etc.Any lawsuits would be limited to the assets of the LLC and not your personal assets (assuming you run the LLC appropriately and the corporate veil is not pierced).

Just ensure your personal funds are not co-mingled and pick a state where it is difficult to pierce the veil.
