Baisden Landlord-Tenant Lawyer, West Virginia

A commercial real estate lease in which the tenant regularly pays not only for the space (as he does with a gross lease) but for a portion of the landlord's operating costs as well. When all three of the usual costs--taxes, maintenance and insurance--are passed on, the arrangement is known as a 'triple net lease.' Because these costs are variable and almost never decrease, a net lease favors the landlord. Accordingly, it may be possible for a tenant to bargain for a net lease with caps or ceilings, which limits the amount of rent the tenant must pay. For example, a net lease with caps may specify that an increase in taxes beyond a certain point (or any new taxes) will be paid by the landlord. The same kind of protection can be designed to cover increased insurance premiums and maintenance expenses.

A restriction on the use of real estate that governs its use, such as a requirement that the property will be used only for residential purposes. Covenants are found in deeds or in documents that bind everyone who owns land in a particular development. See covenants, conditions and restrictions.

An exception to a zoning ordinance, usually granted by a local government. For example, if you own an oddly shaped lot that could not accommodate a home in accordance with your city's setback requirement, you could apply at the appropriate office for a variance allowing you to build closer to a boundary line.

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.

A provision in a deed or will that attempts to restrict ownership of the property -- for example, selling your house to your daughter with the provision that it never be sold to anyone outside the family. These provisions are generally unenforceable.
