Is an LLC needed?

[David Noskiewicz]

So, I have been researching, and researching, and researching...and loving every minute. however, I see so many Investors talking about their LLC. And so many others not. I have an LLC. well, I did, bath and kitchen remodeling, and am about to call the S.O.S. and have it closed. (I am not intrigued by crawling on my hands and knees laying tile, or dry walling any longer) and my question is, Why do some investors have an LLC. and others simply keep their jobs, and just purchase property after property and never went through the "trouble" of setting up a business. Did I miss something extreme? Do I hold off on canceling, and then perhaps, change the business name along with a few other things (ie. updating Articles of Org. ) and starting an actual investing business? I know it's broad and thank you in advance!
