Remodel, Invoiced, Depreciated, No Contractor to pay?!?

Last September I had a rental unit remodeled and the contractor invoiced me for a little over $14k.  

 

The contractor never gave me a W-9 and has since disappeared.

 

The property was placed into service on October 1, 2023.  

 

Without payment, nor even knowing when payment will be accepted, do I start the depreciation last October, do I start once payment has been rendered after W-9, or am I just losing out on this depreciation until I someday can pay him?
