Recorded sales history

Recorded transfers for this building in Miami-Dade County public records, back to Oct 1975. Prices reflect the recorded consideration; transfers the Property Appraiser does not qualify as arms-length are shown unmarked. Nominal-consideration paper transfers (deeds into trusts and LLCs, estate and family transfers, corrective deeds) are part of the record but not sales, and are omitted from this table. Recording lags closing, so the newest sales can take several weeks to appear.
