How would I complete a real estate deed transfer in TN when property is a gift?
And what taxes I have to pay in procentage rate?

Here is a definition: "A gift deed is a deed in which the consideration is not monetary, but is made in return for love and affection. It is a document which transfers property to another as a gift. Such a deed is often used to present someone with a gift. Transfer of a gift deed can be reported as a gift for federal tax purposes." Gift Deed Law & Legal Definition

Here is a form: Form No. 15 - Deed From Husband To Wife. Deed Of Gift

And, you may want to have an attorney prepare or review your project.
