I always worry that correcting them or trying to contradict them will come off as condescending and do more damage than the review itself.How do you all handle reviews like this?

You won't know the ARV correctly or the repair costs so your budgets will be crap.

Your numbers may be correct that its hard to cashflow significantly on a STR with a mortgage in 2024. 

What @Joe Jor said is generally correct.

Correct me if I'm wrong but since the Roth IRA has no tax liability, the depreciation deduction is basically lost.

I do not, but you are correct, there are a bunch out there - mostly China based.  

I've had my contractor pour a leveling liquid over sections of floor and then run LVP or carpet overtop to correct for a few inches (1-3 inches) in drop in a room or two.

You'll have to defend that you did everything correctly.  

And also, since I am the borrower, am I correct in my understanding that I would be subject to a tax on cancellation of debt which would lower my total IRR.I saw many years ago (like in 2017) on BP that note investors were shooting for 10-12% IRR in a zero-interest rate environement. 

Buy quality home or property maintain it correctly treat your tenants by the laws of the jurisdiction and have decent insurance..
