When Applying For A Mortgage What Is Considered Debt
The Financial Balance: Understanding What Counts as Debt in Your Mortgage Application
Navigating the path to a new home is one of the most significant financial maneuvers you will ever undertake. For many, the process feels like a rigorous audit, where every bank statement and credit line is placed under a microscope. As you are preparing to buy, you quickly realize that lenders aren’t just looking at how much money you make; they are obsessively interested in how much you owe. This brings us to a fundamental question: when applying for a mortgage what is considered debt? The answer is more nuanced than simply looking at your credit card balance, and understanding these definitions can be the difference between a swift approval and a frustrating denial.
Whether you are among the first-time homebuyers looking for a cozy starter home, a retiree planning to downsize, or asset-rich individuals seeking for real estate investments, the math remains the same. Self-employed home buyers often find this stage particularly complex, as personal and business liabilities can sometimes blur. In the broader category of preparing to buy, mastering your debt ratio mortgage metrics is essential. It allows you to see your financial health through the eyes of an underwriter, giving you the power to adjust your position before the official application hits the desk.
Understanding the Debt-to-Income (DTI) Ratio
In the world of lending, the most important number isn’t your salary—it is your debt-to-income ratio, or DTI. This is a percentage that shows how much of your gross monthly income goes toward paying off debt. Lenders use this to determine your “bandwidth” for taking on a new mortgage. If your DTI is too high, it suggests that adding a house payment might stretch your finances to a breaking point.
You might find yourself asking, is a mortgage considered debt? In the context of your application, the answer is yes. Lenders calculate your “front-end” DTI (the house payment itself) and your “back-end” DTI (the house payment plus all other monthly debts). Knowing what debt to income ratio for mortgage approvals is required is crucial; typically, lenders prefer a back-end DTI of 43% or lower, though some programs allow for higher thresholds depending on your credit score and cash reserves.
Types of Debt Included in the DTI Ratio Calculation
When an underwriter looks at your credit report, they are looking for recurring, legally binding monthly obligations. These are the items that stick to your financial record and must be paid regardless of your lifestyle choices. In the category of preparing to buy, you should audit the following areas of your life.
Rent or Mortgage Payments
If you currently own a property and plan to keep it (perhaps as a rental), that existing mortgage debt must be included in your ratio. If you are a first-time buyer currently renting, your rent is not included in the “back-end” DTI calculation, but the projected mortgage debt for your new home will be the primary driver of the ratio. Lenders want to ensure that the total mortgage debt across your entire portfolio is manageable.
Loan Payments
This category encompasses everything from the SUV in your driveway to the personal loan you took out for home improvements. Auto loans, boat loans, and any “buy now, pay later” installments that appear on your credit report are counted. Even if you only have six months of payments left, most lenders will still include it in the debt ratio for mortgage unless it is significantly close to being paid off.
Student Loans
Student loans are a major factor for many modern buyers. Even if your loans are in deferment or on an income-driven repayment plan, lenders must account for them. They will often use a percentage of the total balance (usually 0.5% or 1%) as a “placeholder” monthly payment if your actual payment is currently zero. This can significantly impact your mortgage debt calculations, so it is wise to discuss this with your loan officer early.
Credit Card Payments
Lenders do not look at your total credit card balance; they look at the minimum monthly payment required. However, if you are an investor or a high-spender who pays their balance in full every month, that minimum payment still counts against your ratio. If you are trying to improve your debt ratio mortgage standing, paying down these balances to reduce the minimum payment can be a very effective strategy.
Child Support and Alimony
These are legally mandated payments that don’t always appear on a credit report, but you are required to disclose them. Because they are fixed, recurring obligations, they are treated exactly like a car loan or credit card. If you are on the receiving end of these payments, they can often be counted as income, but if you are paying them, they are firmly in the “debt” column.
Debts Typically Excluded from the DTI Ratio
One common point of confusion as people are preparing to buy is the difference between a “debt” and an “expense.” Lenders generally ignore your lifestyle expenses, even if they are high. They are looking for the money you are *contractually* obligated to pay.
- Utilities and Phone Bills: Your electric bill, water bill, and 5G data plan are not considered debt. While they are monthly costs, they are seen as living expenses that can be adjusted.
- Personal Expenses: Your grocery budget, gym memberships, Netflix subscriptions, and dry cleaning bills are excluded from the debt ratio mortgage calculation.
- Insurance Premiums: While you must have homeowners insurance to get a mortgage, your health insurance, life insurance, and existing auto insurance premiums are typically excluded from the DTI.
- Health Expenses: Routine medical costs are not debt. However, if you have a medical bill that has gone to collections, it will appear on your credit report and may need to be addressed.
How to Calculate Your DTI Ratio
Calculating your own ratio is a great analytical exercise to perform before you start house hunting. It gives you a clear view of your purchasing power. Use the following simple table as a template for your own mortgage debt assessment.
| Monthly Obligation | Estimated Amount |
|---|---|
| Proposed New House Payment (P&I, Taxes, Insurance) | $2,800 |
| Car Loan Payment | $450 |
| Minimum Credit Card Payments | $150 |
| Student Loan Payment | $300 |
| Total Monthly Debt | $3,700 |
Now, take that total ($3,700) and divide it by your gross monthly income (before taxes). If you make $100,000 a year, your gross monthly income is $8,333.
$3,700 / $8,333 = 44.4% DTI.
In this scenario, you are slightly above the 43% “sweet spot” that many lenders look for. Knowing this allows you to either look for a slightly cheaper home or pay off the credit card to bring the ratio down.
How Can Your Debt Affect Getting a Mortgage?
Your DTI is the primary engine of your pre-approval. If your debt ratio mortgage is too high, the lender may decline the loan even if you have a perfect credit score. It also affects your interest rate. Borrowers with plenty of “margin” in their DTI are seen as lower risk and may be offered more competitive terms.
For real estate investors or asset-rich individuals seeking for real estate investments, managing this ratio across multiple properties is an art form. It is why many professionals choose to pay off small, high-interest debts entirely before applying for a new loan. By clearing the “clutter” from your credit report, you maximize the amount of mortgage debt the bank will allow you to carry for your next acquisition.
Conclusion: Strategy Over Stress
Understanding what is considered debt is a foundational part of preparing to buy. By categorizing your monthly outflows into “contractual debts” and “discretionary expenses,” you can take control of your financial narrative. Remember that while a mortgage is considered debt, it is also a tool for building long-term equity. The goal isn’t necessarily to have zero debt; the goal is to have a manageable debt ratio mortgage that allows you to grow your net worth without sacrificing your quality of life.
Whether you are a self-employed home buyer organizing your business expenses or a retiree looking to simplify your life, stay focused on the DTI. Pay down the small debts that carry high minimum payments, keep your credit card balances low, and always know your numbers. With a clear understanding of your debt ratio, you can step into the homebuying process with confidence, knowing that you have the financial “room” to turn a house into a home. Happy house hunting!
FAQ's
Yes, in some cases. If you are a self-employed home buyer and can prove that a debt (like a car loan) has been paid out of your business accounts for the last 12 months, many lenders will exclude that payment from your personal DTI. This requires providing 12 months of cancelled business checks or bank statements as proof.
For the DTI calculation, the lender only looks at the minimum monthly payment. However, your total balance affects your “credit utilization,” which impacts your credit score. When preparing to buy, it is a smart move to pay down balances to improve your score, which in turn helps you secure a lower interest rate.
High debt increases the lender’s risk. If your DTI is too high (usually over 43% to 50% depending on the loan type), you may be denied a loan entirely. Even if you are approved, a high DTI can result in a higher interest rate or a requirement for a larger down payment. Asset-rich individuals seeking for real estate investments often pay off small debts before applying to keep their DTI as low as possible.
To find your ratio, add up all your monthly debt payments and divide that sum by your gross monthly income (your income before taxes).
Example: If your debts total $2,000 and your gross income is $6,000, your DTI is 33% ($2,000 / $6,000 = 0.33).
This depends on which side of the check you are on. If you are the one paying alimony, it is considered a recurring legal debt and is included in your DTI. If you are the one receiving alimony, it is considered income, provided you can prove it will continue for at least three years.
Not every monthly bill is considered “debt.” Lenders generally exclude:
Utilities and phone bills: Electricity, water, and cell phone plans.
Personal expenses: Groceries, gym memberships, and streaming services.
Insurance premiums: Health, life, and auto insurance (though homeowners insurance is included in the housing ratio).
When you are preparing to buy, your current rent is usually replaced in the calculation by your future mortgage payment (including principal, interest, taxes, and insurance). However, if you are a real estate investor keeping your current home as a rental, that existing mortgage stays in your DTI calculation unless you can prove the rental income covers the cost.
Even if your student loans are deferred, lenders cannot ignore them. If a monthly payment isn’t listed on your credit report, many lenders will calculate a “placeholder” payment—often 0.5% or 1% of the total loan balance—and include that in your DTI. For first-time homebuyers with high student debt, this is a critical factor to verify with your lender early.
Lenders focus on “fixed” and “recurring” obligations that appear on your credit report. These typically include:
Rent or mortgage payments: Your current housing costs (or the projected payment for the new home).
Loan payments: Auto loans, personal loans, or boat loans.
Student loans: Even if they are in deferment or on an income-driven plan.
Credit card payments: The minimum monthly payment required, not your total balance.
Child support payments: Any court-ordered monthly obligations.
The DTI ratio is the primary tool lenders use to measure your ability to manage monthly payments. It is a percentage that shows how much of your gross monthly income goes toward paying recurring debts. In the preparing to buy phase, knowing your DTI helps you determine exactly how much home you can afford without being “house poor” or facing a loan denial.
