Technically you couldn't spend most your time in NY and still claim residency in FL. Laws require you to spend at least half the year in FL and have done other things besides buy a property to show that you really do live in that state.
Florida won't be your friend if New York comes knocking.

To give this some specificity, I have multiple former colleagues who live in Connecticut and commute to New York who have had their cell phone location data subpoenaed. If you’re going to decamp from New York for tax purposes, actually decamp.
