I have not depreciated my condo rental property since it was put in service in 2019. I read that Form 3115 is needed to depreciate & adjust cost basis for PRIOR years. (1) Can I add it as an asset now with in-service date of 2019 or current year 2024, and not do the 3115 for 'prior'years? (2) How exactly do I enter the 2024 remodel costs and a special assessment for the buillding renovation? (3) Can I enter those costs for 2024 if I don't first add the condo as an asset?
