I loaned my partnership LLC money to pay the monthly interest on loan incurred to buy house to flip in 2018. House sold March 2019. Expense in 2018 or add 2 basis 2019?

LLC had no income in 2018 just expenses.  I also loaned money for yearly renewal, registered agent, amendment to add partner, utilities.   I know that everything else is added to basis, but are these things expensed in 2018 or also added to basis?
