Deductions & credits

When you say, The first year you will be able to claim a depreciation deduction will be in 2020 when the property is ready and available to rent.

 

Are  you saying, once I put my property in service, I have to wait until I file taxes next year to claim the depreciation deduction and repair expense, OR, are you saying that once I put my property in service (March 2020), THEN I can start depreciation deduction and expenses, right now?
