The fullest interest I can have in my ownership of real estate is called having a?

The phrase "fullest interest I can have in my ownership of real estate" refers to having the most complete and unrestricted form of ownership. In real estate terminology, this is best described as a fee simple interest.

Fee simple ownership grants the owner absolute control over the property, which includes the right to use it, lease it, sell it, or pass it on to heirs. This type of estate is not contingent upon any conditions or limitations, giving the owner the highest level of ownership interest recognized by law.

In contrast, a life estate allows an individual to use the property for the duration of their life, after which the ownership reverts to another party, meaning the interest is not full or unrestricted. A leasehold estate refers to temporary ownership granted to a tenant through a lease, lacking the permanence of a fee simple. Joint tenancy involves shared ownership with rights of survivorship among owners, but it does not confer the absolute ownership associated with a fee simple interest.

Thus, fee simple is the most comprehensive and favored form of property interest, embodying full ownership.
