for the home sold, it would be the taxes actually paid in 2025 through escrow (not including escrow deposits) or directly to the real estate tax authority + the prorations on the closing statement for the unpaid taxes for the period you owned it. on the home bought, you got credit for the taxes owed for the period you did not own it. Those credits first offset any payments made (not including escrow deposits) so until the year all those credits are used, there is no deduction
