Permits and tenant turnover — what runs ahead of a listing

Permits come from Miami-Dade County, with job cost and square footage added from the City of Miami's file where the building sits in the city. Arrivals and departures are business-tax receipts opened and closed at this address. None of this is an availability listing. A permit means work was authorised, not that space is for rent, and a closed receipt can mean a business moved, renamed or simply stopped renewing. It is the record that runs ahead of a listing, which is the only part of "what is coming available" that is public at all.
Recorded transfers — county roll + state sale file
Sale history
| Recorded | Price | Qualification | Source | Instrument |
|---|---|---|---|---|
| Mar 2021 | $4,000,000 | not rated | County roll | — |
Prices are the consideration the documentary stamps indicate, as recorded by Miami-Dade County. A qualification code is the property appraiser's judgement of whether a transfer was arm's length; the state publishes it only for the current roll period, so older transfers appear unrated rather than assumed clean. Whether a building is on the market today, and at what price, is not a public record and is not shown here — asking prices, listings and lease terms live in private commercial databases.
