Rental property (converted from primary residence) on market starting Aug ‘20. I didn’t find tenants until Jan ‘21. What rental expenses can be claimed in 2020?

1] Can property tax, HOA, Interest, cleaning, painting and remodeling claimed as expenses in 2020?

2] Does interest, HOA, property tax in 2020 need to be prorated?
3] Can I claim painting and remodeling expenses after Aug ‘20 in full?
