With respect to assets (real or personal property), cost recovery does not begin until the assets are placed in service.
Can you be more specific on just what your property management business is/does?
Do you own the property and rent it out? If so, is this long term rental that a renter would call "home"? Or a short term vacation rental like you would get on VRBO or AirB&B?
Maybe you manage property that others own?
I ask this,because based on my interpretation of what you posted, I'm not clear if this is a SCH C business or SCH E business. This matters for taxes and can also affect (in some instances) how you treat assets such as furniture for the property being rented out.

It actually makes no difference since assets (such as furniture) would not be deducted (directly or via a cost recovery method) until the assets were placed in service.
