Completing W9 for a Single Member LLC

[Brent Bell]

Newbie question here. I know I need a CPA, but didn't think I needed this individual so early in the process. Words of wisdom from experienced veterans here is greatly appreciated.

I formed a single member LLC for asset protection purposes and got an EIN number. I now have my first single family rental in the LLC and the property management company sent me a W9 with their management agreement today.

Reading the instructions on how to fill out the W9, it is not clear to me whether I should be listing my LLC on line 1 or my personal name, with the LLC listed on line 2 as a disregarded entity.

If I list the LLC on line 1, and select LLC in section 3, what is the best option for a buy and hold rental portfolio - C-corp or S-corp?

Thanks in advance for any guidance.  Will be starting my search for a competent, real estate savvy CPA in the morning!
