LLC use of EIN vs SSn

[Lola Brin]

'We are transfering property that is under our name to an LLC. We are planning to use a Special Warranty Deed. We want to continue to use our SSN rather than to get and start filing using a EIN, has anyone had experience if using SSN presence a risk for someone being able to go after personal property outside of the rental since the LLC is tied to your SSN. I would hope with the title under the LLC and a lease would limit your liability to the property under the LLC'.
Lastly, do you really need a separate checking account for each LLC. We have 3 properties. Why couldn't we have one account that we call rentals and maintain a spreadsheet for each property?
