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.; Sell.Do no pricing is published, and the quote stacks a per-user fee with usage-billed AI, WhatsApp, SMS and telephony volumes, so the monthly bill is variable and hard to budget in advance.
  • They diverge on capability: CoStar covers Property and ownership records, Sell.Do covers Lead aggregation.
  • 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.

Sell.Do

  • No pricing is published, and the quote stacks a per-user fee with usage-billed AI, WhatsApp, SMS and telephony volumes, so the monthly bill is variable and hard to budget in advance.
  • The five-user minimum means small brokerages pay for seats they do not use.
  • Aurum PropTech now holds a majority stake of roughly 84 per cent, so product direction serves a listed parent with a wide proptech portfolio, and buyers should get roadmap and data-portability commitments in writing.
  • The product is written around Indian property practice, portals and payment structures, so it has little application outside India and no meaningful presence in other markets.
  • Deep configuration of inventory, price lists and approval workflow is required before go-live, so implementation is measured in weeks and depends on vendor availability rather than self-service setup.
