Cost Segregation - LTR to STR Property

[Nickolas Wolfe]

Good day,

Property background - home was a LTR for 2021 and 2022. In December of 2022, we started to convert it to a STR. In January of 2023, it became an STR.

Big question - in my case, is a cost segregation study worth it if I am not a real estate professional? If a cost segregation study was performed, would we need to start taking bonus in 2021 when the property was a LTR, making the loss passive? 

I would like to offset other Schedule C income for 2023 with the STR bonus depreciation from the cost seg., but it is not looking too promising.
