#40: Glen Rock, New Jersey
Avg Yearly Salary: $76,320
Avg Monthly Cost of Living: $9,230
Top-rated schools, an easy train ride to New York City, and quiet residential streets make Glen Rock highly attractive to families. With many buyers competing for a limited number of homes, prices stay high. New Jersey property taxes, commuting costs, childcare, and home upkeep make the town even more expensive.

A salary of $76,320 provides about $6,360 per month before taxes. That sounds strong, but Glen Rock’s estimated expenses are $2,870 higher. Mortgage payments and property taxes could quickly consume much of one income, leaving households dependent on a second paycheck to cover food, transportation, savings, and other needs.
