Recorded transfers — county roll + state sale file

Sale history

The most recent transfer covered 34 parcels. The price shown is the whole transaction, not this parcel alone, so any per-square-foot figure is measured across everything the deed conveyed. The county record carries no multi-parcel flag for it; the parcels were identified by their identical price, date and ZIP.

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.

Data provenance — public records only

Every fact on this page is drawn from the government records above — no listing sites, no scraped platforms, no third-party images. Facts from public records are uncopyrightable; each tenancy row carries its source and match confidence. Records can lag reality — a business-tax receipt or registration at an address is evidence of occupancy, not a lease confirmation.
