The rights that go with real property can be summed up by the term appurtenances.
When real property is sold, appurtenant rights are ordinarily sold along with it. They can, however, be sold separately, and may be limited by past transactions.
In addition to knowing the boundaries of the land and which items are considered part of the real property (fixtures vs. personal property), homeowners and lenders also need to understand which rights are being transferred along with that parcel of real estate.
One way to understand the rights that accompany real property is to imagine the property as an inverted pyramid, with its tip at the center of the earth and its base extending out into the sky.
An owner has rights to the surface of the land within the property’s boundaries, plus everything under or over the surface within the pyramid.
This includes oil and mineral rights below the surface, and certain water and air rights. Air rights are sometime regulated by each state allowing for air traffic and water rights can differ from state to state.
It is possible, though, for the owner to transfer only some of the rights of ownership to another person.
For example, a property owner may sell the mineral rights to a piece of property, but keep ownership of the farm.
Later, when the land is sold, the mineral rights will most likely stay with the mining company (depending upon the wording of the contract involved) even though the rest of the bundle of rights in the land is transferred to the new owner.
The new owner is limited by the past transaction of the previous owner, and may not sell these mineral rights to another party, nor transfer them in a future sale of the land.
A lender must know if the entire bundle of rights is being transferred (fee simple) or if there are restrictions or past transactions that may limit the current transfer of ownership in any way.
This is important because it may have a great effect on the value of the real property.
Transfer of access rights for a sidewalk to be placed across the front of a subdivision lot generally would not have a significant impact on the value of a piece of land.
Transfer of mineral rights to a mining company, as in the previous example, likely would impact the value.
