2025 Methodology for Determining Winners of CoStar Power Broker Awards

The following criteria represent the methodology used in generating CoStar Power Broker awards for all company and individual categories. Each award is based on transaction data included in CoStar’s commercial real estate database, the largest and most comprehensive database of commercial real estate information. Information in CoStar’s database is verified and continuously updated by CoStar’s Customer Relationship Consultant — comprising the largest commercial real estate research operation of its kind — and available to clients through CoStar SuiteTM, which includes CoStar Property®, CoStar COMPS®, and CoStar Tenant®. Because this information is gathered and confirmed daily, totals and rankings could change as new information is obtained. Brokers are encouraged to provide information on all transactions closed during the calendar year 2025 to ensure they receive full credit for their closed transactions.

The award methodology for all CoStar Power Broker Awards is subject to change at CoStar’s sole discretion.

CoStar Power Broker Leasing Awards for Companies

This award recognizes companies that achieve high levels of leasing transaction volume in 2025 in which a company acted as the agent or broker on any U.S. or Canada office, retail, flex and industrial property lease transaction. The award recognizes companies by the CoStar market in which the company is located, (i.e. Top Leasing Companies in Cincinnati, Top Leasing Companies in Phoenix, etc.) and is calculated using information on signed lease transactions contained in CoStar’s database.

To qualify, lease transactions must meet the following criteria:

 

  • Commercial Property Lease Transactions Only: 
    To be considered transactions must be a signed lease for Office, Office/Medical, Office/Retail, Medical, Retail, Flex, or Warehouse space within a building contained in the CoStar Property database. The transaction may be new or a renewal of a lease, and may be a direct lease or a sublease.
     
  • Signing Date: 
    Lease must have a signing date in calendar year 2025. The move-in date is not taken into consideration.
     
  • Building Status: 
    The status of the building in which the leased space is located is not taken into consideration. Therefore, the lease may be for space located within an existing, under construction, under renovation or a proposed property. Lease transactions are categorized by CoStar’s Building Space Use Type in which the space was leased (Office, Office/Medical, Office/Retail, Medical, Retail, Flex, or Warehouse) regardless of the Building Type of the property.
     

  • Overall Leasing Volume: 
    The overall leasing volume for each company is based on an aggregation of all qualified lease transactions in which the company represented either the tenant or the landlord within the respective CoStar market. The overall leasing volume for each company is calculated as follows: the square footage of each lease transaction is multiplied by the achieved rental rate. If the achieved rental rate is not provided, CoStar’s estimated market rental rate for the building will be substituted, when available.

    This calculation is first done for all lease transactions in which the company represented the tenant. The same calculation is then done for all lease transactions in which the company represented the landlord. The two numbers are added together for an overall leasing transaction number for the company. In transactions where the company represented both the tenant and the landlord, the company will receive 50% of the transaction’s value from the tenant side and 50% from the landlord’s side. In instances where a different company represented the opposing side in the transaction, each company will receive 50% of the transaction’s value. Likewise, if two or more companies worked together on the same side of the deal, each company will receive its proportionate share of the transaction’s value.

     

CoStar Power Broker Sales Awards for Companies

This award recognizes companies that achieve high levels of sales transaction volume in 2025 in which the company acted as the agent or broker in any U.S. or Canada commercial property sales transaction. The award recognizes companies based on the CoStar market in which the company is located (i.e. Top Sales Companies in Cincinnati, Top Sales Companies in Phoenix, etc.) and is calculated using pricing information from closed sales transactions in CoStar’s COMPS database.

  • Closing Date: 
    The property sale must have a closing date in calendar year 2025.
     

  • Overall Sales Volume: 
    The overall sales volume for each company is based on an aggregation of the sales prices for all closed sale transactions in which that company represented either the buyer or the seller. CoStar’s estimated market value of the property is used, when available, in the event a sale price was not provided. The overall sales total is calculated as follows: the total sales dollar volume is calculated for each company in which the company represented a buyer. Then, a sales dollar volume is calculated in which the company represented a seller. The two numbers are added for an overall sales volume number for the company. In transactions where the company represented both the buyer and the seller, the company will receive 50% of the transaction’s value from the buyer’s side and 50% from the seller’s side. In instances where a different company represented the opposing side in the transaction, each company will receive 50% of the transaction’s value. Likewise, if two or more companies worked together on the same side of the deal, each company will receive its proportionate share of the transaction’s value.


     

CoStar Power Broker Leasing Awards for Individuals

This award recognizes individuals who achieve high levels of leasing transaction volume in 2025 in which the individual acted as the agent or broker on any U.S. or Canada office, retail, flex and industrial property lease transaction. Individual CoStar Power Broker leasing awards are presented inthree categories: Office Leasing, Retail Leasing and Industrial/Flex Leasing. The award recognizes individuals by market based on the CoStar market in which the individual is based, and is calculated using information on signed lease transactions contained in CoStar’s database.

To qualify, lease transactions must meet the following criteria:

 

  • Commercial Property Lease Transactions Only: 
    To be considered transactions must be a signed lease for Office, Office/Medical, Office/Retail, Medical, Retail, Flex, or Warehouse space within a building contained in the CoStar Property database. The transaction may be a new or a renewal of a lease, and may be a direct lease or a sublease.
     
  • Signing Date: 
    Lease must have a signing date in calendar year 2025.
     
  • Building Status: 
    The status of the building where the lease occurred is not a factor in the awards. The lease may be for space located within an existing, under construction, under renovation or proposed property. Lease transactions are categorized by CoStar’s Building Space Use Type in which the space was leased (Office, Office/Medical, Office/Retail, Medical, Retail, Flex, or Warehouse) regardless of the Building Type of the property.
     
  • Overall Leasing Volume: 
    Overall leasing volume for each individual is based on an aggregation of the square footages of all the lease transactions in which the individual represented either the tenant or the landlord. The overall volume is calculated as follows: The total square footage of each lease transaction multiplied by the achieved rental rate. If the achieved rental rate is not provided, CoStar’s estimated market rental rate for the building will be substituted, when available.

    This calculation is first done for all lease transactions in which the individual represented the tenant. The same calculation is then done for all lease transactions in which the individual represented the landlord. The two numbers are added together for an overall leasing transaction number for the individual. In transactions where the individual represented both the tenant and the landlord, the individual will receive 50% of the transaction’s value from the tenant’s side and 50% from the landlord’s side. In instances where a different individual represented the opposing side in the transaction, each individual will receive 50% of the transaction’s value. Likewise, individuals who work in brokerage teams will each receive their proportionate share of the transaction’s value as described below.
     

  • Brokerage Teams: 
    To account for individuals who work together as brokerage teams to close a lease transaction, CoStar tracks multiple individual brokers for both the tenant representation and landlord representation for each lease transaction.

    CoStar recognizes that multiple brokers will often appear on a listing for marketing purposes. A broker who is removed from a transaction for the purposes of allocating credit for the Power Broker awards will be permanently removed from the transaction and will not be subsequently added back to the transaction in CoStar’s commercial real estate database.

    In determining an individual’s transaction volume for the 2025 Power Broker award, each individual member of a brokerage team will receive credit equal to the transaction value divided by the number of brokers on the team. For example, a broker working as part of a three-person brokerage team representing the tenant on a transaction will receive credit for one-third of the transaction’s value. In instances where a different broker or brokerage team represented the opposing side, each side will receive 50% of the transaction’s value, divided by the number of brokers on the team, when applicable.
