A few questions people must answer when responding to my ad via anonymous email. 

One of the huge benefits of having a property management company is to remain anonymous as the owner.

Plus, this is a business based on relationships, not online anonymity.

If it's to remain anonymous, create a trust and put it in there.

I also wanted complete anonymity so if its owned by a trust there is no way to pierce that veil.

I haven’t kept up with the legal requirements of owner address in Philadelphia but generally speaking I advise property owners to use a virtual mailbox to list as a mailing address for more anonymity.

The #1 reason we use LLC's is anonymity with tenants.

Pro:cheaper to create and maintain (state fee) You can have multiple child LLC on shelve ready to be used for no cost.You can in theory have only one bank account for all the LLCs and only separate them on paper with excellent bookkeeping.Con:Not recognized in all state, and interpretation of their separation may vary in foreign jurisdictionRelatively recent and not a lot of case lawSpecific operating agreement needed and not all lawyers are very familiar with itMay have some issues when dealing with title or banks who are not used to them.May lower some of your anonymity as will link all the series together.I do have some series LLC and also some vanilla LLCs.

This allows anonymity for management purposes. 

I'd make some anonymous complaints about your competition who are operating illegally.
