Considerable confusion has arisen on account of the double use of the term real property; the term being used to represent both the tangible property itself and interests in such property. Not all interests in real property, however, are considered as real property; estates less than a freehold being considered personal property. A freehold is a life estate or an estate of inheritance. The reason why estates less than freehold are considered real property is to be found in the Feudal system. Under this system a life estate was the only estate which was considered worthy of acceptance by a freeman and all lesser estates were considered of such small importance that instead of being classed with freeholds, they were classed with the less important - personal property.
