Billionaire real-estate magnate Donald Trump likes Facebook.

Trump, known for his real estate investments around the world, has delved into stock picking recently.

"I would invest in it. I'm not a huge Facebook person but everybody I know is big with Facebook and I would invest in it," Trump tells CNBC.

"I think people are interested in investing in Facebook. I think it's going to be very successful. We'll see what happens and we'll see how far it goes. I have a lot of friends that want to buy in Facebook."

Facebook founder Mark Zuckerberg has begun a road show to pitch to investors the benefits of investing in his iconic social network, with a price target in the $28 to $35 range.

Pivotal Research Group analyst Brian Wieser has put a $30 price target on Facebook shares.

"Our conversations with investors to date suggest that concerns around revenue growth and the absence of mobile monetization will linger for some time," says Wieser, according to Reuters.

The company is still worth the hype.

"We would not be surprised if the stock trades up above the IPO price on retail interest in the company over the near term."

Facebook boasts some 900 million users, redefining how people worldwide use the Internet, thus posing a challenge from traditional online heavyweights Google and Yahoo!.

One iconic investor says he won't rush to put money into Facebook because companies of its nature are too hard to value.

"I'm an agnostic on a company like Facebook. Anytime you get a truly extraordinary business — and it's obvious it's an extraordinary business — they're the hardest ones to value," says Warren Buffett, according to CNBC.

"The question is whether five or ten years from now that they will be as extraordinary as they are now or they may keep doing more and more wonderful things — it's just harder to figure out than say Coca-Cola."
