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.

Follow Up Boss

  • Pro plan is priced for a 10 user minimum at $499 per month, with additional seats at $49 per month each
  • Platform plan requires a 30 user minimum at $1,000 per month
  • Calling is not included on the entry Grow plan and costs an extra $39 per user per month
  • Discounted per user rates require annual billing
