Replace windows replacement for Resential Rental Property after tenant move in

Hi, 

I would like to ask if i replaced the windows that cost $12,000 total and got loan in 2024.

Paid $4000 in 2024

and rest $8000 should be paid in 2025 ( loan will be termed and payoff completely in 2025 )

 

1) Do I need to use depreciation as assets for $4000 in 2024 and do same in way for $8000 in 2025?

 

2) I replace Dishwasher and freezer for rental that cost $2000 in total. Can i use "De Minimis Safe Harbor depreciation" and add into "miscellaneous Expense" for deduction on Schedule E as Expenses? Because its under $2500. Again Its for Residential Rental Property  and used for Rental.

 

I think "Section 179" and "Accelerated depreciation" or "Bonus" is not valid as its residential. It will repeated paper works in Schedule E ( however date will be different) How it should get done correctly for Replacement of windows?

 

Thanks
