Bonus depreciation - cost segregation study?

[Gary Tucci]

Anyone have any experience or insight into doing a cost segregation study? Seems like a lot of money to get one but our STR in Indiana was placed in service spring of 2025 and pretty sure it qualifies as non passive. The tax savings of bonus depreciation seem to significant to NOT consider a cost segregation study!! I appreciate any and all feedback.

I spent $2k on a cost seg for a STR this year. It netted $54k in depreciation. I used CSSI and the process was pretty painless.
There are also some DIY options out there. That option was ~$600, but it was my first cost seg so I opted to pay a little more to make sure it got done correctly.
