Percentage Increase in Cost to Live Comfortably: 23.45 percent
Houston is the fourth-largest city in America and one of the places where it’s hard to buy a home, according to a previous study. The $69,405 annual income needed to live comfortably places the city in the middle of the pack, but that amount is up 23.45 percent compared to last year. So, Houston residents might be finding that their dollar isn’t stretching as far in 2018.
