NY and NJ Estate Tax if Either Spouse And/Or I Own a House in FL

Hi, I am considering to try purchase a house in Miami for my family (spouse and 2 kids and I). I am wondering if there are any implications on estate tax (federal and state) you can share regarding the impact of either me and/or my wife owning the house in Florida? We have been filing married filing jointly income tax returns. I own two rental apartments in nyc in NY, a small commercial office nyc, and our apartment in NJ. Would there be any impacts on my potential estate tax in the future if my spouse owns a share or 100% of the house in Miami? Or if I owned let's say 49% or 51% of the house in FL, and my wife owned the other 51% or 49%, then would my permanent state of residence still be FL, that could favorably affect my estate tax in NY and NJ related to my apartments in NY and NJ?
