About CoStar Suite

CoStar Suite is the leading commercial real estate data and analytics platform, providing market data, comparable transactions, property analytics, and portfolio management tools to brokers, owners, and investors. CoStar's portfolio and lease management features allow users to track lease data alongside market benchmarks, enabling real-time comparison of in-place rents against current market conditions.

How Lextract Helps

Lextract provides the lease-level data that populates CoStar's portfolio management and lease tracking features. Rather than manually entering lease terms into CoStar, teams can extract data from lease PDFs and import the structured output. This is particularly useful for portfolio managers tracking lease expirations and comparing in-place rents against CoStar's market rent data to identify below-market and above-market leases.
