What business entity does Trump hold real estate in?

[Jason Noah Choi]

We've had the age-old debate on whether it is better to hold your real estate in an LLC or just under your name. With the debate coming up, I had a shower thought of how he holds his real estate. Trump, itself, is definitely a corporation, but I'm curious how it all works out.

Now, if Jane owns multiple properties and continues to expand; at a certain point, it's possible that Jane will start a corporation to continue to build out her portfolio. Granted, Jane will also be taxed on the corporate level along with the tax on her W2. 

I've heard of individuals using a C-Corp to create a flipping business, but I haven't heard too much on the buy-and-hold front. Without getting into too much of the legality, is there anyone that holds multiple properties in a C-Corp? What benefits have you discovered compared to when you held them privately?
