The question is, whether to initiate a S-Corp or LLC for my passive income.  

The only exception would be if your rental property is in a C-corporation which it most likely is not as that is not a typical structure for real estate investors. 

Would a personal guaranty on a loan pierce the corporate protection of the llc?

I was wondering if I should get incorporated or not for it (LLC or an S corporation were the options I was thinking of).

On the flip side of the coin, there areas currently C or B that a huge new home development is being built right next door, corporate campus or gaining "trendiness" giving tailwind to the area potentially propelling it from C or B to A.

I've been reading, going to meetings and networking, while manage the rentals myself and have a daytime corporate job as well. 

All of them are in Cleveland Corporate limits.

Make a quick logo and some business cards.
