Multi-family rental (unit 1: 1bed 1bath. Unit 2: 2bed 1 bath). In 2023, one unit was remodeled and rented. The other unit also fire damaged will not be ready until 2024.

If both homes on 1 parcel and 1 address, how to go about filing taxes when only 1 home ready especially the depreciation and cost basis, property taxes, etc?
