@Rashid Khalil I will start by saying I'm all for owning investment real estate in LLC's for business planning and to keep your personal name off the docket. Conflicts are inevitable, and if you own enough real estate you will be involved in disputes no matter how well run your operation is. It's the nature of the buisness but the types of disputes you are statistically most likely to encounter don't require the measures you propose.
The objectives as stated in your posts have evolved. There was no mentioning of probtate and tax efficiency. The theme of the thread was anonymity and asset protection (through the lens of liability protection as the owner of a 15 SFH portfolio). You are not alone in your pursuit of these objectives. Unfortunately the mechanics of litigation specific to the common real estate conflicts (premises liability, landlord/tenant/ contractual/payment disputes) are rarely understood. I believe if they were, far less money would be spent on unecessarily complex asset protection systems.
Like most investors who post about this topic on these message boards, you are focused on the measures you beleive will "protect" you when one of these conflicts arise. I urge all real estate investors to prioritize and be proactive in setting up systems that reduce the likelihood of these conflicts from arising in the first place. It's been a consistent theme of posts I've written over the past few years.
To respond to your request for a critique more generally, I go back to what I wrote earlier. In the event one of the common types of conflict arises, what stops an attorney or pro-se plaintiff (when allowed) from filing a claim against the deed holder (whether it is an entity or owned by you individually?) The answer is absolutely nothing. Even if you hire a PM, a defendant still has standing to file a claim against you, the owner. Not to mention, most PM contracts have language in their management contracts requiring the property owner to indeminify them, normally with exceptions for fraud, gross negligence etc.). If the PM is a management company you form (especially as an owner of 15 SFH's) there's no clearer example of an Alter Ego, a common legal theory. In most instances both the deed holder and management company will be named as defendant. In summary, the deed holder almost always gets named as a defendant and once named, only under very rare circmstances are you going to transfer liability to a management company.
Anonymity was already addressed by others.... If you have a loan on the property, someone can easily pull up the mortgage. From a practicailty stand point, if someone really wants to find you, they will. Operate your 15 SFH portfolio well and nobody will care who you are. As an owner of 15 single family homes there's truthfully no need for managment LLC, wyoming LLC's etc. etc. I will not comment on tax and estate planning. That should be reserved for tax and estate professionals, but from an anonymity and asset protction perspective what you are trying to accomplish is overkill.
My advice is to operate a well organized business with good contract management, pay your bills timely and avoid negligence (and certainly gross negligence). If you can consistently accomplish this, ordinary property and general liability insruance is all that's needed as an owner of a 15 SFH portfolio. If you are going to operate your business negligently and certainly gross neglgience, chances are you're going to get caught up in turmoil no matter how much you spend on asset protection.
