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.; MRI Software the portfolio grew by acquisition, so products overlap, interfaces are inconsistent between lines, and moving from one MRI product to another is a migration rather than a configuration change.
  • They diverge on capability: CoStar covers Property and ownership records, MRI Software covers Commercial lease 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.

MRI Software

  • The portfolio grew by acquisition, so products overlap, interfaces are inconsistent between lines, and moving from one MRI product to another is a migration rather than a configuration change.
  • Which product is strong depends on the country: the Australian and New Zealand agency products came from Rockend and Palace, the United Kingdom commercial strength came from Qube, and a reference from one region tells you very little about another.
  • Pricing is quoted, modular and multi-year, so the number that gets a deal approved usually omits connectors, additional modules and the implementation, and the real total arrives later.
  • Implementations take months and need external consultants, which means the cost of ownership includes a services relationship you cannot avoid.
  • Support experience varies by acquired product line, so the service level a reference customer describes may come from a different team than the one that will handle your product.

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.

MRI Software: How is MRI different from Yardi?

Yardi sells one integrated stack and prefers you stay inside it. MRI sells an open platform of modules and connectors, so you keep more third-party systems but you also carry the integration work.

CoStar: Is CoStar pricing published anywhere?

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

MRI Software: Is the product the same in every country?

No. Much of the international line came from acquisitions, so the Australian, New Zealand and United Kingdom products differ from the United States ones in interface, capability and support.

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.

MRI Software: Does MRI publish pricing?

No. Everything is quoted per module with multi-year terms, and implementation is charged separately.

MRI Software: How long does implementation take?

Months rather than weeks for anything at enterprise scale, and it normally requires either MRI professional services or a certified partner.
