The market can hear which Spanish you are speaking
A translated caption is not Spanish-language content, and an audience in Doral, Hialeah and Coral Gables works that out in about four seconds.
Spanish-language material works here when somebody who genuinely speaks it is on camera saying something they know. It fails when an English script is read phonetically by a broker who does not, and that failure is worse than staying in English, because it reads as a firm performing local knowledge it does not have.
Origin matters too. Miami's Spanish is not one accent or one vocabulary, and a Venezuelan owner, a Colombian family office and an Argentine developer all hear the difference. Cast the broker who fits the audience for that asset class rather than assuming one recording covers the county.
Haitian Creole is the gap almost nobody is filling. There is real ownership and real tenancy in Little Haiti and north of it, and very little commercial material addressed to any of it. If somebody on the team speaks it well, that is an opening rather than a box to tick.
Whatever gets recorded, carry the same substance into each language instead of adding a short courtesy version in the second one. A thin translation tells a viewer exactly which audience the firm takes seriously.
