How much debt is too much to buy a house?

Short answer: balances don't disqualify you, payments do

You can owe $60,000 and be approved. You can owe $12,000 and be declined. The number that decides it is your debt-to-income ratio — the share of your gross monthly income (income before taxes) that goes to required monthly debt payments, including the new mortgage.

A $40,000 student loan on an income-driven plan with a $90 payment barely moves the needle. A $28,000 truck loan with a $780 payment can cost you roughly $120,000 of buying power. Same neighborhood of debt, wildly different outcomes, because lenders divide by your income and only care about what leaves your account each month.

So "too much debt" has a working definition: your debt load is too high when adding a realistic mortgage payment pushes your total monthly payments past what the program allows — usually somewhere around 50% of gross income on an automated approval, and closer to 36% if you want the payment to feel comfortable rather than merely permitted.

Which debts count, and which are ignored entirely

This surprises almost every buyer. Underwriters count required, credit-reported obligations — not your cost of living.

Counted: - Car loans and leases (a lease counts even if it ends in three months) - Credit-card minimum payments, not the full balance - Student loans (see the dedicated guide — the payment used isn't always the one you make) - Personal loans, buy-now-pay-later plans that report to credit, and 401(k) loans - Court-ordered alimony and child support you pay - Co-signed loans — if your name is on it, the payment is yours unless someone else can prove twelve months of on-time payments from their own account - Other mortgages, including a home you're keeping or renting out

Not counted: - Groceries, gas, utilities, phone, internet, streaming - Health, auto, and life insurance premiums - Childcare and tuition - Taxes withheld from your paycheck - Retirement contributions

That last list is why an approval can feel too generous. The lender's math has never seen your daycare bill. Yours has to.

The actual limits by loan program in 2026

These are the working ceilings, not promises. Every one of them flexes with the strength of the rest of your file.

Conventional (Fannie Mae / Freddie Mac): the automated underwriting systems — Desktop Underwriter and Loan Product Advisor — routinely approve to about 50% debt-to-income when credit, reserves, and down payment are solid. Manual underwriting is tighter, generally 36% (up to 45% with strong compensating factors).

FHA (Federal Housing Administration loan — a government-backed loan built for buyers with lower credit scores or smaller down payments): the published manual-underwriting guideline is 31% housing / 43% total, but FHA's automated TOTAL Scorecard approves well past that — files in the low-to-mid 50s are common with good credit and reserves. FHA is the most forgiving mainstream program on debt load.

VA (Department of Veterans Affairs loan — a loan for eligible veterans, active-duty service members, and some surviving spouses, usually with no down payment): there is no hard debt-to-income cap. VA uses residual income — the dollars actually left over each month after the mortgage, other debts, taxes, and a regional cost-of-living estimate. Files above 41% get approved every day when residual income is met. This makes VA the strongest option for eligible buyers carrying debt.

USDA (U.S. Department of Agriculture loan — a no-down-payment loan for homes in eligible rural and small-town areas, with income limits): the guideline is 29% housing / 41% total, with a waiver path when credit and reserves are strong.

The practical read: if your ratio is high, FHA and VA give you the most room, and VA gives the most of all.

How to calculate your own number in five minutes

Step 1. Add your gross monthly income — everything before taxes. Salary divided by twelve; hourly is average hours times rate. Self-employed, commission, and bonus income get averaged over two years of tax returns.

Step 2. Pull your credit report and add up the monthly payments listed. Not balances. Use the minimum shown for credit cards.

Step 3. Add a realistic housing payment — principal, interest, property taxes, homeowners insurance, mortgage insurance if you're under 20% down, and HOA (homeowners association — a neighborhood or condo group that charges a monthly or yearly fee and sets community rules; lenders count that fee in your payment) dues if any.

Step 4. Divide total monthly payments by gross monthly income.

Worked example. Gross income $7,500. Car $480, student loan $210, card minimums $95. Proposed housing payment $2,050.

• Debt without housing: $785 → 10.5%
• With housing: $2,835 → 37.8%

That's a comfortable, easily approvable file with room to spare.

Now give the same buyer a $780 truck payment instead of the $480 car: total becomes $3,135, or 41.8%. Still approvable, but roughly $60,000 less house at the same payment comfort. The [debt-to-income calculator](/dti-calculator) runs this instantly, and the [affordability calculator](/affordability) turns the ratio into a price.

The fastest ways to lower the ratio

Ranked by how much they move the number per dollar spent.

1. Pay off a small loan with a large payment. A car loan with $4,800 left and a $600 payment is the best $4,800 you will ever spend — it's worth roughly $90,000–$110,000 of purchasing power. Compare that to putting the same $4,800 toward your down payment, which buys about $4,800 of house.

2. Pay a credit card down below the minimum-payment threshold — or off entirely. Card minimums scale with the balance, so paying $3,000 off a card can remove $90 a month. If a card is paid to zero and closed (or documented as paid in full at closing), the payment can be excluded.

3. Have someone else take over a co-signed loan. If the primary borrower can document twelve months of payments made from their own account, the debt can be excluded from your ratio.

4. Refinance or extend a loan term. Lower payment, same balance. It costs more interest over time but it can be the difference between approval and decline.

5. Switch loan programs. Moving from conventional to FHA, or to VA if you're eligible, can create more headroom than any payoff.

6. Document income you already have. Overtime, part-time work, or a second job with a two-year history often counts and simply wasn't submitted.

What does not help: paying a large loan down without eliminating it. Dropping a car loan from $22,000 to $14,000 does not change the monthly payment, and the payment is the only thing being measured.

The debts that get excluded — and how to prove it

Several debts on your credit report can legitimately be left out of the calculation. This is where an experienced loan officer earns their keep.

• Fewer than 10 remaining payments on an installment loan. Conventional guidelines allow the payment to be excluded when 10 or fewer monthly payments remain, provided the payment isn't large enough to strain the file. FHA uses a similar short-term exclusion.
• Debt paid by a business. Self-employed borrowers can exclude a loan the business pays if twelve months of payments come from a business account and the payment isn't already deducted on the tax return.
• Debt paid by another party. Twelve months of cancelled checks or bank statements from the other person's account.
• Court-ordered debt assigned to an ex-spouse in a divorce. When a divorce decree or separation agreement assigns a debt to the other party, that payment can be excluded immediately — you do not need twelve months of payment history first. Note that a mortgage assigned this way may still require additional documentation. See the [divorce and mortgage guide](/guides/divorced-mortgage-guide).
• Deferred student loans are not excludable. A payment must be used even at $0 due (see the student-loan guide).
• 30-day accounts like a charge card paid in full monthly can be excluded if the file shows it's paid in full each cycle, though funds to cover the balance may need to be verified.

Where the ratio stops being the point

Passing the test is not the same as being ready. Two checks worth running before you spend your full approval.

The take-home test. Recalculate using net pay instead of gross. A 45% ratio on gross income can be 60% or more of what actually hits your bank account. Then subtract childcare, groceries, insurance, and transportation. If nothing's left for savings, the approval is a ceiling you shouldn't touch.

The maintenance test. Homes cost roughly 1% of value per year to maintain, and it does not arrive in tidy monthly increments. Budget $250–$400 a month on a mid-priced home even if no lender asks you to.

The shock test. Could you make the payment if one income dropped 20% for six months? If not, buy less house. The ratio measures whether you can pay today. Reserves measure whether you can keep paying.

Common mistakes

• Paying down balances instead of eliminating payments. The most common wasted money in the entire process.
• Opening credit during the process. A financed sofa or a new car between pre-approval and closing can end the deal. Lenders re-pull credit days before funding.
• Closing old credit cards to "look better." Closing accounts shortens your credit history and raises utilization on what's left. It lowers your score and does nothing for your ratio unless the card had a balance.
• Forgetting the co-signed loan. Buyers routinely omit a car they co-signed for a relative. It's on your report and it counts.
• Assuming a deferred loan is invisible. Deferment does not remove a student loan from the calculation.
• Not asking about exclusions. Short-term payoffs, business-paid debt, and divorce-assigned debt are all excludable with the right documentation, and nobody applies them if you don't raise them.
