If you find that commercial real estate, e.g. land, is available in big chunks which are too expensive for you to buy, you could look at forming a small investor group (with your friends) and buy it together (and split the profits later). In some cases e.g. when a retail boom is expected in a region, you might find it profitable to buy a property that you can convert into a warehouse for the purpose of renting to small businesses. So commercial real estate presents a whole plethora of investing opportunities, you just need to grab it.
