I already know what you're thinking, “I WISH I had a large inheritance coming my way, but what are the odds? Slim to none.” I know it can feel this way, but earning an inheritance is actually not all that uncommon. Sure, it might not be millions of dollars, but if your parents own a house outright and have some savings, then you might just have $20,000+ heading your way someday (after you split it up with your siblings of course), and that's nothing to sneeze at!
