"Physically, property falls into two broad categories:real estate and personal property.Real property is the rights, interests and benefits connected to the real estate. Real estate is the physical parcel of land, improvements to the land (such as clearing and grading), attachments made to the land (such as paving and buildings) and appurtenances (such as easements that cross the parcel or give access to the parcel)."
