Is there a difference between property or real estate taxes?

No, if it's used in the general context. For example asking someone if they paid their property taxes or their real estate taxes is essentially saying the same thing. Technically, however, there are two types of "property" real and personal. Real property is the rights to land and improvements to the land. Personal property is all property other than real property; it's not permanently attached and is, therefore, movable. Examples of personal property include business equipment and furnishings.
