Yes. Florida does not permit self help eviction so any time you wish to remove someone must be done through the court and ultimately if they don't go the sheriff will remove them
Unless you have been paying rent to the primary landlord, you rights as a tenant may have been terminated by eviction or abandonment. While you may not have rights to the apartment, you can bring an action for replevin to recover your furniture. You should consult an experienced lawyer in Miami-Dade County for help in recovering your property

Dear "Do I need police or court help?":
Originally, you had the right to be in the property through a written or oral lease that you had with the owner of record at that time.
You no longer have that lease, as it has expired and the bank now owns the property.
The subrenter is now the tenant of the bank. You have no right to go in to get your things.
I recommend that you call the sheriff on their non-emergency line and see if they can assist.
If they won't, you'll have to file an action with the clerk of courts.
It would be best to see a local attorney to get a lawsuit started.
