Investors spend millions on proprietary indicators to predict which neighborhoods will appreciate next. But one of the strongest leading signals is free, public, and updated daily: Florida Sunbiz business filings.
We analyzed 6.9 million Florida business entities registered with the Division of Corporations, matched their principal addresses to zip codes, and compared formation spikes with median sale price changes over the following two years. The pattern is clear, consistent, and — for most zip codes — a 12–24 month leading indicator of price movement.
Zip codes that saw the largest spikes in new business formations in 2020–2021 experienced 27–54% median price appreciation over the following two years. The signal is strongest in urban core zip codes with high absolute formation counts.
Every Florida LLC, corporation, limited partnership, and trust registered with Sunbiz has a filing date (formation) and a principal address. We extracted the zip code from each principal address, grouped by year, and cross-referenced with our sales database (arm's-length residential sales between $50K and $5M).
| ZIP | Area | Formation Year | New Entities | Price Same Year | Price +2 Years | 2-Year Change |
|---|---|---|---|---|---|---|
| 33166 | Doral / Medley | 2021 | 5,794 | $475,000 | $620,000 | +30.5% |
| 33131 | Brickell | 2021 | 5,571 | $465,000 | $697,550 | +50.0% |
| 33134 | Coral Gables | 2021 | 3,630 | $619,000 | $861,000 | +39.1% |
| 33130 | Downtown / Edgewater | 2021 | 3,052 | $410,000 | $545,000 | +32.9% |
| 33137 | Wynwood / Design District | 2021 | 2,717 | $520,000 | $798,950 | +53.6% |
| 33311 | Fort Lauderdale (west) | 2021 | 2,914 | $283,500 | $370,000 | +30.5% |
| 33009 | Hallandale Beach | 2021 | 3,006 | $375,250 | $455,000 | +21.3% |
| 33023 | Hollywood / Pembroke Park | 2021 | 2,672 | $330,000 | $420,000 | +27.3% |
| 33020 | Hollywood (east) | 2021 | 2,633 | $365,000 | $470,000 | +28.8% |
| 33126 | Airport / Flagami | 2021 | 2,367 | $210,000 | $315,000 | +50.0% |
The 2021 column is particularly striking because of the Northeast-to-Florida migration wave that peaked that year. Companies relocated, new entities formed at their Florida addresses, and residential demand followed 6–18 months later. The zip codes with the highest formation counts in 2021 were essentially predicting where price pressure would land in 2022–2023.
Business formation is a demand signal — not a price signal. When someone registers a new entity in a zip code, it means one of several things:
All three scenarios represent net new demand for housing, office, and commercial space in that zip code. The entity filing precedes the property transaction because people form entities when they arrive or when they intend to buy — not after.
Two patterns break the formation → appreciation link:
Three practical applications:
Across all Miami-Dade, Broward, and Palm Beach zip codes with at least 20 entity formations per year and 20 arm's-length residential sales per year:
| Formation Year | Median 2-Year Price Change (across qualifying zips) | What Was Happening |
|---|---|---|
| 2019 | +15–20% | Pre-COVID baseline, steady migration |
| 2020 | +30–40% | COVID flight begins, remote work unlocks FL |
| 2021 | +25–50% | Peak migration wave, Brickell/Doral/Wynwood surge |
| 2022 | +10–18% | Rate hikes begin, formation pace slows |
| 2023 | Mixed (−10% to +20%) | Market bifurcation: luxury holds, mid-market softens |
The 2023 data is the most nuanced: some zips (33139 South Beach, 33012 Hialeah) still showed strong formation→appreciation. Others (33132 Downtown, 33178 West Dade) showed formations flattening and prices softening. The signal is no longer uniformly bullish — it's becoming a selection tool, not a blanket buy signal.

Entity data: Florida Division of Corporations (Sunbiz), 6.9 million entities with filing dates and principal addresses. We filtered to entities with formation_state = 'FL' and valid Florida zip codes. Sales data: county deed records for Miami-Dade, Broward, and Palm Beach, filtered to arm's-length residential sales between $50K and $5M. Median prices computed per zip per year with a minimum threshold of 20 sales to avoid small-sample distortions.
Broker One Research is the data-journalism arm of Broker One. Every post under this byline is backed by an original SQL analysis across our proprietary datasets: 2M Florida parcels from county appraisers, 4.6M active and historical MLS listings, 6.9M Florida business entities from Sunbiz, FEMA flood zones, building permits, code violations, and Census ACS demographics. We publish our methodology — row counts, filters, date ranges — so readers can evaluate the rigor of every finding. We use median-based metrics rather than means to keep MLS data-entry outliers out of headline numbers.
