It's difficult, though not impossible, for a renter or someone else who sues your LLC to "pierce the veil" and get through to your personal assets.

Some say NV is kinder insofar as protecting us re piercing the corporate veil..

I'm a relatively new member here, but my company has been investing in Pierce/King/Snohomish county pretty successfully for the last few years.

I'll just comment that ANY entity can have the corporate veil pierced and thus offer no effective protection. 

I worry that if we use the operating account from our main LLC for each property we purchase in other LLCs, that that money used would now open the main partnership's account for piercing the corporate veil.

I went to Pierce for a couple courses.

There needs to be separation between the entities and the owners, otherwise you risk a court "piercing the corporate veil" (lifting the corporation or LLC's veil of limited liability) and hold the owners personally liable for the entity's business debts.

The fees associated with filing and maintaining, plus taxes on the back end if you sell out of the llc.If everything isnt done correctly inside the llc, a good lawyer will find a way to pierce the veil anyway.But the concensus was it all depends on your personal level of risk, and what would help you sleep better at night.Hope that helps.

I am moving to Pierce County (Tacoma, Puyallup) in August and I am planning to buy and hold properties out there.
