Any loopholes past NACA recipients are aware of? 

I plan to do cost seg study and get bonus depreciation (and will actively participate as per IRS rules) but need to confirm if this would still work if buy STR under LLC and I can still be eligible for that STR loophole?

Insurance companies will try their best not to fulfill claims by looking for loopholes. 

Tricks, loop holes?   

Real estate professional status, as well as the short term rental loophole are a few big ones.

Recently a perspective tenant found a loophole in my lease after it was signed.

Great post @AJ Wong, but dammit if that "pro" article says it is a loophole.

This is where the short-term rental tax loophole can help. 

All I want to do is to not leave any obvious loopholes. 

This closing of a tax loophole used by many small investors and couples will definitely encourage people not to buy rental or vacation property they might eventually want to retire in.
