CompStak Review 2025

CompStak is the first crowdsourced CRE database that collects verified comps from executed lease and sale transactions. Its crowdsourcing process is unique to the industry and differs from any other source of comps. Over 40K brokers, independent appraisers, and researchers submit their comps to CompStak through its Exchange platform in exchange for credits. Those credits can then be exchanged for access to specific comps needed to complete their current transactions. 

CompStak gives users the most comprehensive view of an asset and the surrounding market and submarket by utilizing lease comps, sale comps, loan information, and market analytics. CompStak’s unique platform provides hard-to-find data points such as actuals for starting rents, free rent, TI amounts, rent increases, term, expiration dates, net effective rent, cap rates, net operating income, true buyer/seller, and more. CompStak covers over 3.4M properties in 105 markets encompassing the entire country.

Pros Explained

The most accurate, verified lease and sales comp data: CompStak captures actual transaction data directly from executed leases and sales, including verified starting rents, rent escalations, concessions, and net effective rent. Unlike other platforms that rely on estimates or listings, CompStak provides highly accurate, on-the-ground data from brokers, appraisers, and researchers, enabling better decisions based on actual lease and sales transactions rather than approximations​​.

Data from an extensive network of over 40K brokers, appraisers, and researchers: CompStak’s crowdsourced model is distinct in the industry. Its contributors earn credits to access data by submitting their comps, creating a dynamic exchange of up-to-date CRE data. This extensive network ensures broad, diverse data coverage across markets and submarkets, giving users access to comprehensive and frequently updated lease and sales comps​​.

Unique data validation process to ensure accuracy: CompStak has a rigorous data validation process. It starts by sourcing data from its trusted network of brokers, appraisers, and researchers and sending that data through AI algorithms to flag suspicious data and improve quality. Next, the data is personally reviewed and cross-verified by their team of commercial real estate analysts.  Finally, CompStak’s community feedback system allows CompStak members to update comps with additional information to continually improve the data in the CompStak system. CompStak’s verification ensures that all data submitted meet high standards, creating a trusted data source that clients can use for underwriting, valuation, and competitive analysis​.

Advanced market analytics tools: CompStak’s analytics tools, including Map Analytics, its Data Visualization tool, Chartbuilder, its Data Aggregation tool, and Market Dashboard, allow users to track market trends, visualize rent growth, and analyze lease terms across various submarkets and asset types over time. These tools support in-depth research with options to filter by property type, lease size, location, and more, making them powerful resources for identifying trends and creating custom market reports​.

Easy-to-use interface: CompStak’s user-friendly platform features over 60 search filters, allowing users to refine results based on specific criteria such as lease type, transaction type, transaction size, and building class. Users can customize lists, export data, and even set notifications for new data relevant to saved searches, making the platform efficient for routine analysis and reporting​.

Cons Explained

Limited multifamily data: While CompStak excels with office, retail, and industrial data, complete multifamily income insights require a RealPage subscription.

No property owner contact info: Users looking for a tool that gives property owner contact information for prospecting purposes may find this lacking compared to other platforms.

CompStak offers robust features that allow users access to accurate CRE data and insights. 

Lease Comp Data

CompStak’s lease comp data offers insights into lease transactions with detailed, verified data points such as starting rent, rent escalations, tenant improvements, and net effective rent. CompStak collects this data from a network of 40K brokers, appraisers, and researchers who share recent lease deals in exchange for access to other data on the platform. This crowdsourced model allows users to access real-time, reliable lease data that reflects actual transaction details, not just listings. Users can filter by factors such as tenant, landlord, building class, and submarket, providing flexibility for market research, asset management, and underwriting. All data is exportable as well.

Sale Comp Data

CompStak’s sale comp data includes transaction details for property sales, providing verified information from public records and its Exchange network. Sale data complements lease data, allowing users to see a property’s leasing and ownership history, track building ownership, and obtain information on sale prices, buyers, and terms. This dual approach provides a unique context not typically available from public sources, such as financing terms and market-specific insights, which can assist in competitive analysis and valuation.

Property Data

CompStak’s property profiles include data on property attributes, recent transactions, tenant information, and more. CompStak offers a cohesive view of each property by integrating data from multiple sources, including active leases, average rents by property type, publicly recorded mortgages, and loan information, including CMBS loan data directly from a partnership with Trepp. The property profile helps users understand the full context of a property’s financial and physical status, which is especially useful for acquisitions, portfolio management, and property comparisons. To see detailed income data for multifamily, users will also need a separate subscription to RealPage Market Analytics, which they can purchase through CompStak.

CMBS Loan Data

CompStak One includes a limited snapshot of CMBS loan data in partnership with Trepp to give users a holistic view of CRE data. Within one consolidated experience, CompStak users can see important loan data like lender name, maturity dates, loan to value, and more. With loan information, users can evaluate property financials to uncover distressed opportunities and derive actionable insights from comps to analyze market health.

Chartbuilder

Chartbuilder is CompStak’s tool for creating custom, trend-based analyses at the market or submarket level. Users can aggregate and visualize data on metrics like rent growth, lease terms, and occupancy rates. With the flexibility to compare specific submarkets or broader regions, Chartbuilder enables in-depth analysis, such as tracking trends over time. It’s tailored for research teams who need to identify market trends or benchmark performance, making it ideal for generating insights that support investment strategy and forecasting.

Market Dashboard

The Market Dashboard provides an interactive overview of market-level metrics, including visualizations of trends, rent distributions, and tenant migration patterns across different property types. Users can drill down to submarkets, filter by date ranges, and adjust criteria like tenant industry and lease size. Additional features like heat maps and charts allow users to explore how different factors impact market conditions. The dashboard also includes market commentaries with references for some of the major markets in the country. The Market Dashboard is a helpful tool for asset managers and researchers who need customizable, visual insights into market dynamics for strategic planning and risk assessment.

Map Analytics

Map Analytics is CompStak’s tool for visualizing CRE data trends in a map. Its core functionality includes a Market Rent Heat Map to see where rents are high or low by asset class within a market, a Tenant Industry Map to visualize the concentration of tenant industries, a Space Type Map to see where various types of spaces tend to concentrate (like retail industrial space vs office, vs retail), and finally a dynamic Lease Expiration map that shows you lease expirations over time. This feature is particularly fun because it plays like a video and can actually let you see in which months or years an area of a market has a lot of leases rolling. 

CompStak Map Analytics

CompStak’s interface is easy to use, allowing for a smooth user experience with multiple ways to filter and analyze data. Users can search by property address, nearby comps, or related properties. The platform also allows users to customize alerts on saved searches, providing real-time data updates. CompStak’s features and options enable users to access property and market data with a short learning curve.

CompStak offers multiple support options. General support is available through a website chatbot, email, and a shared helpdesk. At the same time, paid subscribers receive a customer success manager as the main point of contact to answer any questions. The customer success team is highly responsive, helping users optimize their experience through training and research assistance for advanced data needs. 

CompStak uses value-based pricing, which requires potential clients to discuss specific needs in a sales call before receiving a quote. While general pricing isn’t available online, CompStak provides flexibility, tailoring prices based on company size and data requirements. Most subscribers are on the CompStak One plan, which includes leasing, sales, CMBS data, and analytics. Access to the Exchange Platform for brokers and appraisers providing verified lease and sale data is free.

CoStar

CoStar is a widely recognized and utilized CRE data company. It provides a comprehensive database of commercial properties and market intelligence to a broad spectrum of users, including investors, brokers, landlords, and tenants. The platform offers various services and tools that enable users to access detailed information about available properties, market trends, property analytics, comparables, lease and sale listings, and research reports.

While CoStar overlaps with CompStak on some leasing and sales data, it lacks comp data, which is CompStak’s bread and butter. 

Real Capital Analytics (RCA)

RCA offers a comprehensive platform with data on property transactions, sales, financings, re-financings, foreclosures, development sites, and mortgage debt information.
