I will go against the previous posters thoughts and will argue that you should get an LLC per property. Spending $100 a year to get liability and asset protection is a cheap insurance.
Will an LLC protect you against act where you are personally responsible? Of course not.
But will an LLC protect your personal assets against a major lawsuit arising from a tenant claim? Yes
Are there cases of piercing the veil of the company? They are extremely rare and results from gross mismanagement of the member/owner that can be easily avoided.
Now, if you have a personal liability attack against you (your kid is involved in a vehicle homicide for instance), an LLC in a charging order state will protect your real estate from being taken away from you.
Last if you use anonymity protection with an LLC, you will avoid a lot of possible nightmare stories of harassment, threats, vandalism, libel to your home, work and social media by a disgruntled tenant.
It may also protect you from frivolous lawsuits as an asset search by ambulance chaser lawyers will return nothing.
To answer your questions:
Yes if your LLC is disregarded for tax purpose, there will be no change to your tax return. Your LLC will collect the rent and then turn it back to you.
I would suggest that you watch Clint Coons YouTube channel that goes in depth in asset protection for real estate investor and the proper use of LLC.
