I have spent hours researching Florida Statute 83, specifically 83.201 about him not repairing things in our apartment, but that section seems to refer to "untenantable" units. Ours is not. I understand I can give him a 7-day letter to cure or we will either move, which we can't afford to do just yet, or we will withhold rent (we will actually put it into the Court registry and request a hearing). I'm just not sure if we are to serve him certified mail, in person or regular mail and I'm also not sure if we need to let him know we are withholding rent and/or depositing it into the Court Registry. Our rent is due the 1st, so I need to make sure he has the letter 7 days prior, which would be the 25th. How do I "serve him"? And other than what needs to be repaired, how specific should it be?
