📰 WBN – Your Debt-To-Income Ratio Decides Where You Can Live

Lenders and landlords both judge you by one ratio. Here are the U.S. and Canadian limits, and the fastest way to improve yours.

Before a lender looks at your credit score or a landlord reads your references, one number has often already decided your answer: your debt-to-income ratio, or DTI. It is your monthly debt payments divided by your gross monthly income. It can cap the home you buy, the rate you get and the apartment you rent, and it is the one housing number you can change without earning a dollar more.

U.S. households now owe $18.77 trillion, including $13.12 trillion in mortgages, according to the New York Fed's latest published report (Q2 2026). That is a lot of applicants about to meet this ratio, often for the first time at the moment they get declined.

By The Numbers

$18.77 trillion: total U.S. household debt, Q2 2026. Mortgages account for $13.12 trillion, credit cards $1.26 trillion, auto loans $1.71 trillion and student loans $1.65 trillion (New York Fed).
43%: the long-standing back-end DTI ceiling for FHA loans. FHA can go higher with compensating factors.
36% to 45%: Fannie Mae's conventional range. Automated underwriting can approve up to 50% when credit and cash reserves are strong.
39% and 44%: Canada's two limits for insured mortgages, called GDS (housing costs only) and TDS (housing plus all other debt), both measured against gross income.
Contract rate + 2%, or 5.25%: the Canadian stress-test rate, whichever is higher. Lenders calculate your ratios at this rate, not the rate you will actually pay.
2.5x to 3x: the gross-income-to-rent multiple most U.S. landlords ask for.
1.52% vs. 1.29%: the share of mortgage balances moving into serious delinquency, Q2 2026 vs. Q2 2025 (New York Fed). It is a small number moving in the wrong direction, and it is one reason underwriters watch ratios closely.

How The Ratio Works

Add up your required monthly debt payments: car loan, student loans, minimum credit card payments, and the new housing payment. Divide by your gross monthly income, before taxes.

Housing gets counted twice. U.S. lenders look at a "front-end" ratio (housing cost alone) and a "back-end" ratio (housing plus every other debt). Canada does the same under different names: GDS is the front-end ratio and TDS is the back-end one. In Canada, housing cost also includes property taxes, heat and half of any condo fees.

Groceries, utilities, phone bills, insurance premiums and most subscriptions are not usually counted. DTI measures what you owe, not what you spend.

A Worked Example

Say a household earns $6,000 a month before taxes. It has a $400 car payment, $300 in student loans and $100 in credit card minimums. That is $800 in existing debt. The household finds a place with a $1,800 monthly housing cost.

U.S. back-end DTI: ($1,800 + $800) ÷ $6,000 = 43.3%. That is right at the FHA ceiling and above the comfort zone for most conventional loans.
The landlord test: At 3x rent, the household needs $5,400 a month. It clears that easily. The ratio, not the multiple, is what could trip it up with a stricter property manager.
Canadian TDS cap: 44% of $6,000 is $2,640. Subtract $800 in debt and the most this household can put toward housing is $1,840. With no debt at all, the 39% GDS cap would allow $2,340. Those $800 in monthly debts cost this household roughly $500 a month in housing power.

Now suppose the household pays off the car. The back-end DTI drops to ($1,800 + $400) ÷ $6,000 = 36.7%, a full six points, without earning a dollar more.

The lesson is in the subtraction. Every dollar of monthly debt payment comes out of your housing budget almost dollar for dollar, which makes debt payments the cheapest part of the ratio to change.

Key Developments

Approvals run looser than the rule of thumb, but the rule of thumb is still the safer target. The old "28/36" guideline (housing at 28% of income, everything at 36%) remains a measure of comfort. Real approvals often go well above it. A 45% ratio doesn't become comfortable because a lender will fund it.

The stress test makes Canada's numbers harder than they look. A Canadian borrower is qualified at a higher rate than the one on the mortgage contract. A household that calculates a 38% TDS at its actual rate may land above 44% at the qualifying rate and be declined. The test applies when you borrow new money. Renewals at the same lender with no increase in the loan are generally exempt.

Landlords are borrowing the lender's playbook. Most U.S. landlords still lead with the 2.5x to 3x gross income rule. Some also check total debt, and collections from a past landlord tend to hurt more than ordinary credit card balances. An applicant who clears the income multiple but carries heavy debt can still be turned down.

Business Impact

For advisors, mortgage professionals, real estate agents and insurance professionals, DTI is the cleanest bridge from a vague conversation to a specific one. "Can I afford a house?" is hard to answer. "What is your DTI today, and which two debts would change it most?" has an answer on the back of an envelope.

It also points to a service gap. Many buyers and renters first calculate their DTI after they have fallen in love with a listing. Offering the calculation first, before the search starts, helps clients make better offers and reduces failed applications. For employers running financial wellness programs, a short DTI explainer is a high-value, low-cost benefit for staff planning a move.

Why It Matters

Debt feels like something you pay down to feel better. Housing is where it becomes a hard limit. A ratio you never calculated can decide which neighborhood you can enter, what rate you are offered and whether you are approved at all.

The practical move is to run the number before you shop, not after:

Calculate your DTI today.
Target the debt with the highest monthly payment relative to its balance. Retiring a high payment helps the ratio more than retiring a high balance.
Avoid new financing, such as a car loan or store card, in the months before an application.
In Canada, run your numbers at the stress-test rate, not your hoped-for rate.

A companion piece in this series looks at the other side of the same decision: how to plan financially for the move itself, from deposits and moving costs to the budget gap between two homes.
