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.
