A right to use another person's real estate for a specific purpose. The most common type of easement is the right to travel over another person's land, known as a right of way. In addition, property owners commonly grant easements for the placement of utility poles, utility trenches, water lines or sewer lines. The owner of property that is subject to an easement is said to be 'burdened' with the easement, because he or she is not allowed to interfere with its use. For example, if the deed to John's property permits Sue to travel across John's main road to reach her own home, John cannot do anything to block the road. On the other hand, Sue cannot do anything that exceeds the scope of her easement, such as widening the roadway.

To take effect, or to benefit someone. In property law, the term means 'to vest.' For example, Jim buys a beach house that includes the right to travel across the neighbor's property to get to the water. That right of way is said, cryptically, 'to inure to the benefit of Jim.'

A nonrefundable fee charged by a landlord when a tenant moves in. The fee covers the cost of cleaning the rented premises after you move out, even if you leave the place spotless. Cleaning fees are illegal in some states and specifically allowed in others, but most state laws are silent on the issue. Landlords in every state are allowed to use the security deposit to clean a unit that is truly dirty.

For income and capital gains tax purposes, the value that is used to determine profit or loss when property is sold. Often the basis is what you paid for the property, 'adjusted' to reflect improvements made or damage incurred while you own the property. See stepped-up basis, carryover basis.

A way for married couples to hold title to property, available in Arizona, California, Nevada, Texas and Wisconsin. It allows one spouse's half-interest in community property to pass to the surviving spouse without probate.

The basis of a contract. Consideration is a benefit or right for which the parties to a contract must bargain; the contract is founded on an exchange of one form of consideration for another. Consideration may be a promise to perform a certain act -- for example, a promise to fix a leaky roof -- or a promise not to do something, such as build a second story on a house that will block the neighbor's view. Whatever its particulars, consideration must be something of value to the people who are making the contract.

A form filed with the county recorder's office to put on record your right to a homestead exemption. In most states, the homestead exemption is automatic--that is, you are not required to record a homestead declaration in order to claim the homestead exemption. A few states do require such a recording, however.

A commercial real estate lease in which the tenant pays a fixed amount of rent per month or year, regardless of the landlord's operating costs, such as maintenance, taxes and insurance. A gross lease closely resembles the typical residential lease. The tenant may agree to a 'gross lease with stops,' meaning that the tenant will pitch in if the landlord's operating costs rise above a certain level. In real estate lingo, the point when the tenant starts to contribute is called the 'stop level,' because that's where the landlord's share of the costs stops.

A deed that transfers whatever ownership interest the transferor has in a particular property. The deed does not guarantee anything about what is being transferred, however. For example, a divorcing husband may quitclaim his interest in certain real estate to his ex-wife, officially giving up any legal interest in the property. Compare grant deed.
