Do you need to trademark if you brand your house with a "name"?

[Mike Shemp]

Hi All,

My wife and I are planning on purchasing a vacation home to rent out in the Outer banks next year or late this year.  I noticed many of the homes there have "names", and usually some kind of plague, or sign outside displaying it to add some charm to the house.  

Do you need to trademark research before "naming" your house, or can you pretty much call your house anything you like naming a pet?

Any thoughts or opinions would be greatly appreciated!

Mike
