Absorption Rate – the rate at which available commercial properties are leased or sold in a given market over a specific period. It is used to measure the supply and demand of real estate within a particular area.
Appraisal – the process of determining the market value of a property, usually conducted by a certified appraiser. It involves an in-depth analysis of the property, comparable sales, market conditions, and highest and best use.
Build-to-Suit – a real estate development project where a property is constructed specifically for a tenant’s needs, often with the tenant providing input on the design and layout. The property is typically leased upon completion.
Brownfield – a property where the presence, or potential presence, of hazardous substances, pollutants, or contaminants may complicate the property’s expansion, redevelopment, or reuse. Brownfields often require environmental cleanup before they can be developed.
Capitalization Rate (Cap Rate) – a rate used to convert the income generated by a property into its market value. It is calculated by dividing the property’s net operating income by its current market value. A lower cap rate indicates a higher property value relative to income.
Catch-Up Rent – rent paid by a tenant to a landlord to compensate for rent that was deferred or underpaid, typically as a result of a lease renegotiation or concession agreement.
Comparable Sales (Comps) – data from similar properties that have recently sold, used to estimate the value of a subject property. Adjustments are made for differences between the comparable and subject properties.
Condemnation – the legal process through which the government exercises its right of eminent domain, taking private property for public use. Condemnation can also refer to the act of declaring a property unfit for use, often due to unsafe conditions.
Cost Approach – a valuation method that estimates the value of a property by calculating the cost to replace or reproduce the property, minus depreciation, plus the value of the land. This method is often used for unique or special-purpose properties.
Depreciation – a reduction in the value of a property over time due to factors such as wear and tear, age, or obsolescence. Depreciation can be physical (related to the condition), functional (related to outdated design), or external (related to neighborhood decline or market conditions).
Discounted Cash Flow (DCF) – a valuation method that estimates the value of an investment based on its future cash flows, which are discounted to their present value. It is widely used in real estate to appraise income-producing properties.
Easement – a legal right granted to another party to use a portion of the property for a specific purpose, such as utility lines, access roads, or pipelines, without transferring ownership of the property.
Eminent Domain – the legal power of the government to take private property for public use, with compensation provided to the property owner. It is typically used for public infrastructure projects like roads and schools.
Environmental Site Assessment (ESA) – an evaluation process that identifies potential environmental contamination liabilities of a property. A Phase I ESA is a preliminary investigation, while a Phase II ESA includes sampling and testing for contaminants.
Escalation Clause – a provision in a lease that allows for periodic increases in rent, typically tied to an index like the Consumer Price Index (CPI) or increases in property operating expenses.
External Obsolescence – a loss in property value caused by external factors, such as changes in the neighborhood, market conditions, or zoning laws, rather than the property itself. This form of depreciation is typically outside the control of the property owner.
Fee Simple Interest – the most complete form of property ownership, where the owner has absolute ownership rights, subject only to governmental powers such as taxation, eminent domain, police power, and escheat. This interest includes the right to use, sell, lease, and bequeath the property.
Functional Obsolescence – a form of depreciation resulting from design or layout flaws, outdated technology, or changes in market preferences that reduce a property’s value or utility.
Going Concern Value – the total value of an operating business, including its real estate, personal property, and intangible assets like goodwill. For appraisals, the real estate component is often separated from the business value.
Green Building – a property designed, built, or operated to reduce environmental impact and improve energy efficiency. Green buildings may use sustainable materials, incorporate energy-efficient systems, and aim to meet certifications like LEED (Leadership in Energy and Environmental Design).
Gross Lease – a type of lease where the tenant pays a flat rental amount, and the landlord covers all operating expenses, such as property taxes, insurance, and maintenance.
Hard Costs – the direct, tangible expenses associated with the construction or improvement of a property, including materials, labor, and equipment. Hard costs are contrasted with soft costs, such as fees for architects or consultants.
Highest and Best Use (HBU) – the reasonably probable and legal use of vacant land or an improved property that results in the highest value. It must be legally permissible, physically possible, financially feasible, and maximally productive.
Income Approach – a method of appraising property value based on the income the property is expected to generate. This approach is commonly used for income-producing properties like office buildings, apartments, and shopping centers.
Investment Value – the value of a property to a particular investor, based on that investor’s specific requirements, tax situation, or financing. It can differ from the market value, which reflects general market conditions.
Leasehold Interest – the interest held by a tenant (lessee) under a lease agreement. It grants the tenant the right to use and occupy the property for a specific period in exchange for rent, but not full ownership.
Leased Fee Interest – the ownership interest held by a landlord (lessor) under a lease. It entitles the owner to receive rental payments for the use of the property and recover possession of the property upon lease termination.
Loan-to-Value Ratio (LTV) – a financial metric used by lenders to assess risk, calculated by dividing the amount of a loan by the appraised value of the property. A lower LTV ratio means less risk to the lender.
Market Value – the most probable price that a property should bring in a competitive and open market, under all conditions requisite for a fair sale, assuming both buyer and seller are acting prudently and knowledgeably, and the price is not affected by undue stimulus.
Net Operating Income (NOI) – the income generated from a property after deducting operating expenses but before deducting taxes, interest, and depreciation. NOI is used to evaluate the income-generating potential of real estate.
Plottage – the increase in value resulting from the combination of two or more adjacent parcels of land into one larger parcel. This is also known as the principle of assemblage.
Pro Forma – a financial projection that estimates the future income, expenses, and profitability of a property based on certain assumptions. It is commonly used by investors and appraisers to assess the financial feasibility of real estate investments.
Rentable Square Footage (RSF) – the total square footage of a property or space that can be rented to tenants, including usable areas like offices as well as common areas such as lobbies and hallways.
Right of First Refusal (ROFR) – a contractual right that gives a tenant or buyer the first opportunity to purchase or lease a property before the owner can offer it to third parties. If the holder of the ROFR declines, the owner is free to offer it to others.
Sales Comparison Approach – a method used in appraising property value by comparing it to similar properties (comparables) that have recently sold in the area. Adjustments are made for differences between the subject property and the comparables.
Soft Costs – expenses that are indirectly related to construction projects, such as architectural fees, engineering services, permits, legal fees, and insurance. These are in contrast to hard costs, which cover materials and labor.
Special Purpose Property – a property that has limited use or cannot easily be adapted to other uses without significant modification. Examples include schools, churches, and hospitals, which often require specific appraisals due to their unique characteristics.
Stabilized Property – a property that has reached a stable level of occupancy, typically achieving market rates and a normal turnover rate for tenants. Stabilized properties are attractive to investors as they provide predictable income streams.
Surplus Land – land that is part of a larger property but not currently needed for its highest and best use. Surplus land can often be sold or developed separately without affecting the main use of the property.
Tenant Improvements (TI) – alterations or improvements made to a rental space by or for the tenant, often tailored to the tenant’s specific needs. These costs can be covered by the landlord, tenant, or both, depending on the lease agreement.
Triple Net Lease (NNN) – a lease agreement in which the tenant pays not only rent but also property taxes, insurance, and maintenance costs. The landlord typically has little financial responsibility for the property’s operating expenses.
Usable Square Footage (USF) – the portion of a commercial space that can be exclusively used by the tenant, not including common areas like restrooms, lobbies, or hallways.
Vacancy Rate – the percentage of all available units in a rental property that are vacant or unoccupied at a given time. High vacancy rates can indicate weak demand, while low rates suggest strong demand.
Zoning – the division of land into areas (zones) by the local government to regulate the use, density, and design of buildings and land use. Zoning helps maintain organized urban development and land use planning.
