# Provenance findings — live discovery on top Miami-Dade closed deals (TK-10708)

Ran 2026-08-19. Discovery = WebSearch (search-engine query, not broker scraping). Candidate
broker domains joined from usre.firm (440 FL commercial firms w/ websites). Classification:
**broker_owned** (in firm set) · **first_party** (owner/property-brand or CRE trade press) ·
**marketplace_gated** (Crexi/LoopNet/CoStar — automated access GATED) · **none**.

| deal | price | best asset found | domain | class | confidence |
|---|--:|---|---|---|--:|
| 1111 Brickell Ave, Miami | $274.4M | property brochure on owner site | 1111brickell.com | first_party | 0.85 |
| 1111 Brickell Ave, Miami | — | deal story | cre-sources.com | first_party (trade press) | 0.9 |
| 1111 Brickell Ave, Miami | — | listing page | loopnet.com | **marketplace_gated** | — |
| 1751 Collins Ave, Miami Beach | $270M | redevelopment article | floridayimby.com | first_party (trade press) | 0.6 |
| 1751 Collins Ave, Miami Beach | — | (no broker OM found) | — | none | — |
| 700 Brickell Ave, Miami | ~$443M* | multiple deal stories | therealdeal.com, credaily.com, bisnow.com, miamitodaynews.com | first_party (trade press) | 0.9 |
| 700 Brickell Ave, Miami | — | broker named (CBRE) but no public OM | cbre.com | broker_owned (no asset link) | 0.3 |

\* 700 vs 701 Brickell disambiguation needed; addresses adjacent.

## Verdict (feasibility)
1. **CRE trade-press coverage exists for EVERY significant closed deal** (therealdeal, credaily, bisnow,
   miamitoday, cre-sources) → the most consistent, lowest-risk **Tier-1 link** yield.
2. **Owner/property-brand brochures** exist for trophy standing assets (1111brickell.com) → Tier-1 first-party.
3. **Broker OMs rarely surface for CLOSED deals** — an OM is pulled once the sale closes. Even when a broker
   is named (CBRE sold 700 Brickell), no public OM link. → **OM harvesting belongs to a future ACTIVE-listings
   feed, not the closed-deal feed.**
4. **Marketplace hits (LoopNet) are common** → correctly classified GATED; do not auto-fetch.

## Recommendation
- **Primary = Tier-2 self-generated closed-sale recaps** (owned, zero-risk) — already built + generating.
- **Enrichment = Tier-1 links to CRE trade-press coverage + owner brochures** per deal (link-only, robots-respecting).
- **Defer** broker-OM harvesting until an active-listings feed exists; keep it Tier-3/gated meanwhile.
- **Upgrade path for exact broker match:** populate broker_of_record_history.county_fips/ain so the state-level
  firm-domain join becomes a per-property broker resolution.
