The world would be a scary place if real estate wasn't around. I honestly don't know what would happen if there wasn't professionals to sell and buy homes, buildings and land. Im sure if real estate didn't exist there would be some other type of system of getting a home because its a necessity. Real estate has been around for so long. The ways of selling a home or land and buying it has been around forever. I feel like it is the basics on how business came around in the world. Kind of like the selling and trading of goods. There would be a decrease in the pollution and global warming affects because of all the new construction homes that are being built just to be sold and high prices. If real estate want round people might just sleep on the streets and in the grass.
