If I sell a home & then purchase a new home in the same tax year & pay property taxes on both,are they both considered my main home when claiming my prop tax deductions?

I owned 2 homes during same tax year at different times in different states. Would they both be considered my main home for property taxes. Or would one be considered a main home and one a secondary home? I paid property taxes on both. Do I lump the property taxes for both together as main home? Or split between main and secondary?
