Building Homes - Separate LLC?

[Misty Wood]

I am going to be building 3-5 spec homes to sell. Do you recommend getting an LLC for each one? If yes, do I need to setup up separate bank accounts for each one and make sure I am using the correct checking account for each individual home each time I buy or pay expenses? Or, can I have one bank account and classify the expenses to each property for tax and liability purposes?
