Fee simpleIn English law, a fee simple or fee simple absolute is an estate in land, a form of freehold ownership. A "fee" is a vested, inheritable, present possessory interest in land. A "fee simple" is real property held without limit of time (i.e., permanently) under common law, whereas the highest possible form of ownership is a "fee simple absolute," which is without limitations on the land's use (such as qualifiers or conditions that disallow certain uses of the land or subject the vested interest to termination).
Ground rentAs a legal term, ground rent specifically refers to regular payments made by a holder of a leasehold property to the freeholder or a superior leaseholder, as required under a lease. In this sense, a ground rent is created when a freehold piece of land is sold on a long lease or leases. The ground rent provides an income for the landowner. In economics, ground rent is a form of economic rent meaning all value accruing to titleholders as a result of the exclusive ownership of title privilege to location.
Land tenureIn common law systems, land tenure, from the French verb "tenir" means "to hold", is the legal regime in which land owned by an individual is possessed by someone else who is said to "hold" the land, based on an agreement between both individuals. It determines who can use land, for how long and under what conditions. Tenure may be based both on official laws and policies, and on informal local customs (insofar higher law does allow that).
PropertyProperty is a system of rights that gives people legal control of valuable things, and also refers to the valuable things themselves. Depending on the nature of the property, an owner of property may have the right to consume, alter, share, redefine, rent, mortgage, pawn, sell, exchange, transfer, give away, or destroy it, or to exclude others from doing these things, as well as to perhaps abandon it; whereas regardless of the nature of the property, the owner thereof has the right to properly use it under the granted property rights.
Real estateReal estate is property consisting of land and the buildings on it, along with its natural resources such as growing crops (eg. timber), minerals or water, and wild animals; immovable property of this nature; an interest vested in this (also) an item of real property, (more generally) buildings or housing in general. In terms of law, real is in relation to land property and is different from personal property while estate means the "interest" a person has in that land property.
