If you're happy with your appreciation and want to protect it, Option 3 seems most wise. 

To protect myself I don't want tenants knowing my personal address etc. 

Don't hold your breath.In the future, I recommend you consider using a property manager that can protect you from mistakes like this.

Focus on Tax EfficiencyTax-Loss Harvesting: Use taxable accounts to offset gains with losses, minimizing your tax bill.HSA Contributions: If you have access to a Health Savings Account (HSA), max it out.

Many people get so focused on asset protection and have nothing to protect.  

Lenders will lower the LTV on this type of collateral to protect themselves.

The government's interst is in collecting taxes in a way that protects homeowner interests.

@John McGuire, while this is ultimately a question for both an attorney (are you actually creating any real protection by holding in an LLC) and a thorough review of your actual mortgage agreement regarding transfer of ownership, I will say two things:Typically, services don't care if you transfer ownership with your mortgage.  

YOU FAILED TO PROTECT YOU - YOUR OWN SELF-PROTECTIVE RESPONSIBILITY - PROTECTION OF YOUR INVESTMENT - and Protection of your own earnest monies utilized. 

How do we protect ourselves from a tenant causing us significant damage in excess of the deposit amount?
