Suze says any score below 700 is considered low, so it's more important than ever to give your credit a boost. Landlords—and even employers—are starting to look at that number very closely. "[A low FICO score implies] you're not paying your bills on time, and if you're not paying your bills on time, why should a landlord think you're going to be able to pay his her rent?" Suze says. "Employers are starting to check FICO scores. Because if you're not good with your own money maybe you won't be good with the company's money either."
