MID-YEAR 2010 – HOUSTON

Terms & DefinitionsAvailability Rate: The ratio of available space to total rentable space, calculated by dividing the total available square feet by the total rentable square feet.

Available Space: The total amount of space that is currently being marketed as available for lease in a given time period. It includes any space that is available, regardless of whether the space is vacant, occupied, available for sublease, or available at a future date.

Build-to-Suit: A term describing a particular property, developed specifically for a certain tenant to occupy, with structural features, systems, or improvement work designed specifically for the needs of that tenant. A build-to-suit can be leased or owned by the ten-ant. In a leased build-to-suit, a tenant will usually have a long term lease on the space.

Buyer: The individual, group, company, or entity that has pur-chased a commercial real estate asset.

Cap Rate: Short for capitalization rate. The Cap Rate is a calcula-tion that reflects the relationship between one year’s net operating income and the current market value of a particular property. The Cap Rate is calculated by dividing the annual net operating income by the sales price (or asking sales price).

CBD: Abbreviation for Central Business District. (See also: Central Business District)

Central Business District: The designations of Central Business District (CBD) and Suburban refer to a particular geographic area within a metropolitan statistical area (MSA) describing the level of real estate development found there. The CBD is characterized by a high density, well organized core within the largest city of a given MSA.

Class A: A classification used to describe buildings that generally qualify as extremely desirable investment-grade properties and command the highest rents or sale prices compared to other buildings in the same market. Such buildings are well located and provide efficient tenant layouts as well as high quality, and in some buildings, one-of-a-kind floor plans. They can be an archi-tectural or historical landmark designed by prominent architects. These buildings contain a modern mechanical system, and have above-average maintenance and management as well as the best quality materials and workmanship in their trim and interior fit-tings. They are generally the most attractive and eagerly sought by investors willing to pay a premium for quality.

Class B: A classification used to describe buildings that generally qualify as a more speculative investment, and as such, command lower rents or sale prices compared to Class A properties. Such buildings offer utilitarian space without special attractions, and have ordinary design, if new or fairly new; good to excellent design if an older non-landmark building. These buildings typical-ly have average to good maintenance, management and tenants. They are less appealing to tenants than Class A properties, and may be deficient in a number of respects including floor plans, condition and facilities. They lack prestige and must depend chiefly on a lower price to attract tenants and investors.

Class C: A classification used to describe buildings that gener-ally qualify as no-frills, older buildings that offer basic space and command lower rents or sale prices compared to other buildings in the same market. Such buildings typically have below-average maintenance and management, and could have mixed or low tenant prestige, inferior elevators, and/or mechanical/electrical systems. These buildings lack prestige and must depend chiefly on a lower price to attract tenants and investors.

Construction Starts: Buildings that began construction during a specific period of time. (See also: Deliveries)

Contiguous Blocks of Space: Space within a building that is, or is able to be joined together into a single contiguous space.

Deliveries: Buildings that complete construction during a specified period of time. In order for space to be considered delivered, a certificate of occupancy must have been issued for the property.

Delivery Date: The date a building completes construction and receives a certificate of occupancy.

Developer: The company, entity or individual that transforms raw land to improved property by use of labor, capital and entrepre-neurial efforts.

Direct Space: Space that is being offered for lease directly from the landlord or owner of a building, as opposed to space being offered in a building by another tenant (or broker of a tenant) trying to sublet a space that has already been leased.

Existing Inventory: The square footage of buildings that have received a certificate of occupancy and are able to be occupied by tenants. It does not include space in buildings that are either planned, under construction or under renovation.

Flex Building: A type of building designed to be versatile, which may be used in combination with office (corporate headquarters), research and development, quasi-retail sales, and including but not limited to industrial, warehouse, and distribution uses. A typi-cal flex building will be one or two stories with at least half of the rentable area being used as office space, have ceiling heights of 16 feet or less, and have some type of drive-in door, even though the door may be glassed in or sealed off.

Full Service Rental Rate: Rental rates that include all operating expenses such as utilities, electricity, janitorial services, taxes and insurance.

Gross Absorption: The total change in occupied space over a given period of time, counting space that is occupied but not space that is vacated by tenants. Gross absorption differs from leasing Activity, which is the sum of all space leased over a certain period of time. Unless otherwise noted Gross Absorption includes direct and sublease space.

Growth in Inventory: The change in size of the existing square footage in a given area over a given period of time, generally due to the construction of new buildings.

Industrial Building: A type of building adapted for such uses as the assemblage, processing, and/or manufacturing of products from raw materials or fabricated parts. Additional uses include warehousing, distribution, and maintenance facilities. The pri-mary purpose of the space is for storing, producing, assembling, or distributing product.

Landlord Rep: (Landlord Representative) In a typical lease trans-action between an owner/landlord and tenant, the broker that represents the interests of the owner/landlord is referred to as the Landlord Rep.

Leased Space: All the space that has a financial lease obligation. It includes all leased space, regardless of whether the space is currently occupied by a tenant. Leased space also includes space being offered for sublease.

Leasing Activity: The volume of square footage that is commit-ted to and signed under a lease obligation for a specific building or market in a given period of time. It includes direct leases, subleases and renewals of existing leases. It also includes any pre-leasing activity in planned, under construction, or under renovation buildings.

Market: Geographic boundaries that serve to delineate core areas that are competitive with each other and constitute a generally accepted primary competitive set of areas. Markets are building-type specific, and are non-overlapping contiguous geographic designations having a cumulative sum that matches the boundar-ies of the entire Region (See also: Region). Markets can be further subdivided into Submarkets. (See also: Submarkets)

Net Absorption: The net change in occupied space over a given period of time. Unless otherwise noted Net Absorption includes direct and sublease space.

Net Rental Rate: A rental rate that excludes certain expenses that a tenant could incur in occupying office space. Such expenses are expected to be paid directly by the tenant and may include janitorial costs, electricity, utilities, taxes, insurance and other related costs.

New Space: Sometimes called first generation space, refers to space that has never been occupied and/or leased by a tenant.

Occupied Space: Space that is physically occupied by a tenant. It does not include leased space that is not currently occupied by a tenant.

Office Building: A type of commercial building used exclusively or primarily for office use (business), as opposed to manufactur-ing, warehousing, or other uses. Office buildings may sometimes have other associated uses within part of the building, i.e., retail sales, financial, or restaurant, usually on the ground floor.

Owner: The company, entity, or individual that holds title on a given building or property.

Planned/Proposed: The status of a building that has been announced for future development but not yet started construction.

Preleased Space: The amount of space in a building that has been leased prior to its construction completion date, or certificate of occupancy date.

Price/SF: Calculated by dividing the price of a building (either sales price or asking sales price) by the Rentable Building Area (RBA).

Property Manager: The company and/or person responsible for the day-to-day operations of a building, such as cleaning, trash removal, etc. The property manager also makes sure that the vari-ous systems within the building, such as the elevators, HVAC, and electrical systems, are functioning properly.

Quoted Rental Rate: The asking rate per square foot for a par-ticular building or unit of space by a broker or property owner. Quoted rental rates may differ from the actual rates paid by tenants following the negotiation of all terms and conditions in a specific lease.

RBA: Abbreviation for Rentable Building Area. (See also: Rentable Building Area)

Region: Core areas containing a large population nucleus, that together with adjacent communities have a high degree of eco-nomic and social integration. Regions are further divided into market areas, called Markets. (See also: Markets)

Relet Space: Sometimes called second generation or direct space, refers to existing space that has previously been occupied by another tenant.

Rentable Building Area: (RBA) The total square footage of a building that can be occupied by, or assigned to a tenant for the purpose of determining a tenant’s rental obligation. Generally RBA includes a percentage of common areas including all hall-ways, main lobbies, bathrooms, and telephone closets.

Rental Rates: The annual costs of occupancy for a particular space quoted on a per square foot basis.

Sales Price: The total dollar amount paid for a particular property at a particular point in time.

Sales Volume: The sum of sales prices for a given group of build-ings in a given time period.

Seller: The individual, group, company, or entity that sells a par-ticular commercial real estate asset.

SF: Abbreviation for Square Feet.

Single-Tenant: Buildings that are occupied, or intended to be occupied by a single tenant. (See also: Build-to-suit and Tenancy)

Sublease Space: Space that has been leased by a tenant and is being offered for lease back to the market by the tenant with the lease obligation. Sublease space is sometimes referred to as sublet space.

Submarkets: Specific geographic boundaries that serve to delin-eate a core group of buildings that are competitive with each other and constitute a generally accepted primary competitive set, or peer group. Submarkets are building type specific (office, industrial, retail, etc.), with distinct boundaries dependent on different factors relevant to each building type. Submarkets are non-overlapping, contiguous geographic designations having a cumulative sum that matches the boundaries of the Market they are located within (See also: Market).

Suburban: The Suburban and Central Business District (CBD) designations refer to a particular geographic area within a metro-politan statistical area (MSA). Suburban is defined as including all office inventory not located in the CBD. (See also: CBD)

Tenancy: A term used to indicate whether or not a building is occupied by multiple tenants (See also: Multi-tenant) or a single tenant. (See also: Single-tenant)

Tenant Rep: Tenant Rep stands for Tenant Representative. In a typical lease transaction between an owner/landlord and tenant, the broker that represents the interests of the tenant is referred to as a Tenant Rep.

Time On Market: A measure of how long a currently available space has been marketed for lease, regardless of whether it is vacant or occupied.

Under Construction: The status of a building that is in the process of being developed, assembled, built or constructed. A building is considered to be under construction after it has begun construc-tion and until it receives a certificate of occupancy.

Vacancy Rate: A measurement expressed as a percentage of the total amount of physically vacant space divided by the total amount of existing inventory. Under construction space generally is not included in vacancy calculations.

Vacant Space: Space that is not currently occupied by a tenant, regardless of any lease obligation that may be on the space. Vacant space could be space that is either available or not avail-able. For example, sublease space that is currently being paid for by a tenant but not occupied by that tenant, would be considered vacant space. Likewise, space that has been leased but not yet occupied because of finish work being done, would also be con-sidered vacant space.

Weighted Average Rental Rate: Rental rates that are calculated by factoring in, or weighting, the square footage associated with each particular rental rate. This has the effect of causing rental rates on larger spaces to affect the average more than that of smaller spaces. The weighted average rental rate is calculated by taking the ratio of the square footage associated with the rental rate on each individual available space to the square footage associated with rental rates on all available spaces, multiplying the rental rate by that ratio, and then adding together all the resulting numbers. Unless specifically specified otherwise, rental rate averages include both Direct and Sublet available spaces.

Year Built: The year in which a building completed construction and was issued a certificate of occupancy.

YTD: Abbreviation for Year-to-Date. Describes statistics that are cumulative from the beginning of a calendar year through what-ever time period is being studied.

CoStar Markets & Submarkets

In analyzing metropolitan areas in the U.S., CoStar has developed geographic designations to help group properties together, called Regions, Markets and Submarkets. Regions are the equivalent of metropolitan areas, or areas containing a large population nucleus, that together with adjacent communities have a high degree of economic and social integration. Regions are then divided into Markets, which are core areas within a metropolitan area that are known to be competitive with each other in terms of attracting and keeping tenants. Markets are then further subdivided into smaller units called Submarkets, which serve to delineate a core group of buildings that are competitive with each other and constitute a generally accepted competitive set, or peer group.
