As in some loophole that allows investment in real property through a tax exempt entity?   

I will qualify for REP status based on STR loophole.  

I have another property that was an Airbnb for 7 years (now is a LTR) and for 2 out of the 7 years, it met all the criteria for the STR ‘loophole’ to apply and I was able to offset losses against W-2 income. 

I would also ensure you can even qualify for the cost seg by making sure you either qualify for REPS(real estate professional status) or STR loophole (short term rental loophole)

The other way is using the short term rental loophole but you have to be the person spending the most time in managing the asset which may not be worth it for you. 

I bought a SFH in Canton Ohio last year with the goal of making it a MTR due to the location (STR is NOT an option due to regulations but it is close to various hospitals) and the 4-car garage (makes for a lot of options).Long story short is I quickly acquired 2 other properties right after and spent all my focus setting these 2 properties up for doing the STR loophole for tax purposes (which was a complete success!). 

Is anyone investing into STRs and taking advantage of the tax loophole?!!?

Schedule E).So, the STR rental still goes on Schedule E (not C), but the checkbox they're referring to is not on Schedule E because the difference in how STRs with material participation (the "STR loophole") is not on Schedule E, it's a difference in how it's handled on FORM 8582, which is where the passive activity loss rules are applied.

In the short term rental loop hole there is no loss limitation and that has the potential to be your best option for offsetting W-2 income.
