Accessed 2026-06-21.\n\n**Confidence.** Verified for the 3-year minimum (NAR primary); single-source/industry-consensus for the upper-end \"5+ years\" framing.\n\n**Caveats.** \"Minimum of 3 years\" is the floor; individual MLSs commonly carry more. The 5+ year framing is Realtyna's vendor account, not NAR policy.\n\n**Implication / use.** Floor figure for the historical layer's depth. Use as the conservative baseline; PropTx's 3/5 figures are board-specific.","rationale_body":null,"metadata":null,"links":{"outgoing":[{"slug":"research-brief-mls-data-inside-the-box-ontario-june-2026","title":"Research notes (capture-layer): inside the MLS box — what an Ontario member agent's account exposes, what goes unused, and what they're licensed to do with it (June 2026)","kind":"research-notes","scope":"business","link_type":"depends-on"},{"slug":"vow-password-protected-historical-sold-deeper-layer","title":"VOW (Virtual Office Website) — password-protected, requires established broker-consumer relationship, carries the deeper historical/sold/off-market layer","kind":"reference","scope":"business","link_type":"relates-to"}],"incoming":[{"slug":"research-brief-mls-data-inside-the-box-ontario-june-2026","title":"Research notes (capture-layer): inside the MLS box — what an Ontario member agent's account exposes, what goes unused, and what they're licensed to do with it (June 2026)","kind":"research-notes","scope":"business","link_type":"relates-to"}]},"created_at":"2026-06-21T10:45:32.881Z","updated_at":"2026-06-21T10:45:32.881Z"}
