Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
CoStar
- Per-seat licensing with no published rate makes budgeting for headcount growth unpredictable, since adding users typically requires a new negotiation rather than a self-service upgrade.
- CoStar actively pursues legal action against password sharing and unauthorised access, which is a genuine compliance and litigation risk for a firm that is loose about login discipline, intentionally or not.
- A June 2026 antitrust lawsuit names CoStar alongside major brokerages over an alleged price-fixing scheme, a live legal matter that could affect the company standing or practices during a long-term contract.
- Multi-year contract structures reduce a buyer flexibility to switch providers even if a cheaper or better data source emerges during the term.
- The breadth of the platform (property, hospitality via STR, lease admin) means a firm often pays for modules it does not use just to access the specific data set it needs.
RealPage
- Its revenue management product is the subject of US antitrust litigation alleging it enabled rent price coordination between landlords, which is a material consideration and not a resolved matter
- Quote-only enterprise pricing with modules billed separately, so total cost is hard to establish up front
- Implementation is a long project, and migrating portfolio accounting is genuinely disruptive
- Aimed at large portfolios; small landlords find it far heavier than the problem
