Primary Conversion, Depreciation Questions

[Ayo Odusanya]

Good morning, 

I'm just about to convert a property from a primary to a rental and i had a few questions regarding deprecation.

I purchased the home in 2019 for 295K, and it is now worth $450K. I plan to do a quit claim deed to transfer the property from me to my LLC and then convert it to a rental property starting next year. Current remaining mortgage is $240K at 2.5%

Few questions regarding this:

1. What is the number i use to estimate by base line depreciation: 295, 450, or 240K

2. How does bonus depreciation work? do i add this to base line depreciation, or does that replace baseline?

Thanks for the help!
