Housing experts call rent "affordable" when it takes no more than 30% of a household's income. By that yardstick, renters in many U.S. metros are stretched well past the line — in the most burdened cities, the typical renter spends nearly 40% of their income just on rent. This guide ranks the most and least rent-burdened metro areas and explains a surprising pattern at the top of the list: college towns.
What is rent burden?
Rent burden is the share of a household's income that goes to gross rent. The widely-used affordability threshold is 30%: spend more than that and you're considered "rent burdened," with too little left for food, transportation, savings, and emergencies. Spend more than 50% and you're "severely" burdened. The chart ranks metros by their median rent-to-income ratio — a measure of how squeezed the typical local renter is.
The most rent-burdened cities
The most burdened metros push toward 40% of income spent on rent. Strikingly, the top of the list is dominated not by famously expensive coastal giants but by college towns — places anchored by a big university. The reason is simple math: these cities are full of students, who have little or no income but still pay rent, which drags the median rent-to-income ratio sky-high. It's less a sign of an unaffordable city than of a population with unusually low reported incomes.
The least rent-burdened cities
At the other end are metros where rent takes a more manageable share of income — closer to the low-to-mid 20% range. These tend to be mid-sized cities in the Midwest and South with solid wages and a healthy supply of housing relative to demand. Where building is easier and incomes aren't dominated by students or low-wage service work, rent eats a smaller slice of the typical paycheck, leaving renters more breathing room.
Why the ranking can mislead
Rent burden is a useful affordability gauge, but it has a quirk worth knowing: because it divides rent by income, any place with lots of low-income residents — students, retirees, service workers — will look highly burdened even if rents are modest. That's why a college town can rank above a genuinely pricey metro. The most meaningful comparisons are between similar kinds of cities, and the headline figure is best read alongside actual rent prices and local wages rather than on its own.
Frequently asked questions
What does rent burden mean?
It's the share of household income spent on rent. Above 30% is considered 'rent burdened,' and above 50% 'severely burdened,' leaving too little for other essentials.
Which cities are the most rent-burdened?
College towns dominate the top of the list, where the typical renter spends close to 40% of income on rent — largely because students with little income still pay rent, dragging the ratio up.
Why do college towns have high rent burden?
Because rent burden divides rent by income, and college towns are full of students with little or no income who still pay rent — pushing the median rent-to-income ratio very high.
Which cities are the least rent-burdened?
Mid-sized Midwest and South metros with solid wages and ample housing supply, where rent takes a more manageable share of income — closer to the low-to-mid 20% range.
What is an affordable rent-to-income ratio?
The standard threshold is 30% — spending more than that on rent is considered unaffordable, leaving too little for food, transport, savings, and emergencies.
