You would then go to the bank and open a new business account for each DBA to ensure the funds are separate and you have to leave paper trails to make sure you never pierce the corporate veil.

I won't spend unlimited amounts of money for perfect protection (incidentally, corporate veils can be pierced--and, given what I know about how judges think, the more draconian the injury, the more penniless the plaintiff, and the more wealthy the defendant, the more likely some judge will come up with a creative solution to pierce the veil.

Please do yourself a favor and save a lot of time a agony and go to jakeandgino.com they are two great guys that have a put together an amazing site all about buying multifamily properties...they have blogs, podcasts, a book they wrote called Wheelbarrow Profits, buy it!

Especially as a long term keep. 10-20 years from now this mortgage/cashflow agony will sound like a joke.

The other way would be to pierce the veil by proving the comingling of funds and/or the owner did keep business and personal separate.   

From a tax perspective, there is no effect of taking an owner draw from the rental earnings sitting in your LLC's bank account.However--and I'm saying this personally, not professionally as I am not an attorney and therefore not licensed to speak to legal matters--from a legal perspective, in all your dealings with the LLC, you must take care that you are not doing something that would give a creditor or legal opponent the opportunity to pierce the corporate veil and go after your personal assets.

I have a great property manager in King and Pierce county and so I talked her into "trying" out Thurston county.

Single member LLC is just an alter ego for yourself and easily pierced.. if you have a true partners ship IE other members then its a much better protection device but then all partners get sued. also a major component in my mind is what kind of real estate are you going to do?
