The short version

  • Each has a real cost: 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.; Yardi Voyager implementation frequently costs as much as or more than the first year of licence fees, and the contract clock usually starts before the portfolio is live.
  • They diverge on capability: CoStar covers Property and ownership records, Yardi Voyager covers Full property accounting.
  • Prices and features above were last checked on 1 September 2026.

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.

Yardi Voyager

  • Implementation frequently costs as much as or more than the first year of licence fees, and the contract clock usually starts before the portfolio is live.
  • Module-based pricing means the quoted per-unit rate covers far less than most operators assume, and adding resident portals, procurement or utility billing repeatedly reopens the budget.
  • Reporting beyond the standard set often requires Yardi consultants or a specialist partner, so internal teams stay dependent on paid services for routine changes.
  • Parts of the interface remain dense and dated, which lengthens onboarding for site staff and drives some operators to buy a separate front-end product.
  • Exporting a full portfolio history to another platform is slow and costly, so switching decisions are effectively made once a decade rather than at each renewal.

Answered from the vendors’ own pages

CoStar: Can multiple people share one CoStar login to save cost?

No. Terms explicitly prohibit this, and CoStar has an active pattern of suing individuals and firms for unauthorised access under shared credentials.

Yardi Voyager: Does Yardi publish Voyager pricing?

No. Only Breeze, the small portfolio product, has published per-unit rates. Voyager is quoted per unit per module against annual minimums.

CoStar: Is CoStar pricing published anywhere?

No. It is quote-only, licensed per named user, on multi-year contracts.

Yardi Voyager: How long does implementation take?

Months rather than weeks for anything beyond a small single-asset-class portfolio, and professional services are charged separately.

CoStar: Is there a current legal risk in signing with CoStar?

A June 2026 antitrust lawsuit names CoStar and several major brokerages over an alleged price-fixing conspiracy; buyers with long-term contracts should track that litigation.

Yardi Voyager: Is Voyager suitable under 1,000 units?

Usually not. Yardi steers smaller portfolios to Breeze or Breeze Premier, and the Voyager cost structure rarely justifies itself at that size.
