If a cost segregation study is done in early 2025 can it still be applied to our 2024 taxes to utilize the larger bonus depreciation?

I would suggest calling a title company rep and running this by him. 

There are property management companies that handle everything—from guest check-ins to maintenance—so you don’t have to worry about being hands-on.

no rent coming in but expenses were low - just utilities and insurance. 

And in most cases, reading a receipt and knowing which property/my management company it is tied to (done automatically by separate accounts linking to my software), even if I don't do a very good job documenting, I have enough to go back and justify almost any expense.  

So I'm asking, What is the best way to utilize the results they both gave me and narrow it down?

They will sometimes cover some of the damage with lots of back and forth.Look into companies like Waivo and Safely.

There are companies who buy properties and flip them for large profits each month.

I personally stay away from turnkey companies.

You could easily buy a turnkey home through a company like mine, Real Wealth Network, and its the same thing minus the 15% fee.
