How Debt Can Affect Your Mortgage Approval

How Your Debt Can Affect Your Mortgage Approval

When applying for a mortgage, lenders look at more than just your income and credit score. Your existing debt and monthly debt payments can also have a significant impact on how much you may qualify to borrow.

Whether you are a first-time homebuyer, refinancing your current mortgage or renewing with a new lender, understanding how your debt affects your mortgage application is important.

 

Things You Should Know

When a lender reviews your mortgage application, one of the things they want to determine is whether you can comfortably manage a mortgage payment along with your existing financial obligations.

Your income is an important part of this assessment, but lenders also consider your recurring debt payments.

For example, you may have:

  • Credit card balances
  • Car loans or leases
  • Lines of credit
  • Student loans
  • Personal loans
  • Other mortgages
  • Alimony or support payments
  • Other ongoing financial obligations

The more of your monthly income that is already committed to debt payments, the less room there may be for a new mortgage payment.


Your Debt-to-Income Ratios Matter

Mortgage lenders commonly use debt-service ratios to assess whether a borrower can take on additional debt.

Two important calculations are Gross Debt Service (GDS) and Total Debt Service (TDS).

Gross Debt Service (GDS)

GDS looks at your housing-related expenses compared with your gross household income.

Depending on the mortgage application, housing costs can include:

  • Mortgage principal and interest
  • Property taxes
  • Heating costs
  • A portion of applicable condominium fees

GDS helps lenders assess how much of your income would be required to maintain your home.

Total Debt Service (TDS)

TDS goes one step further by including your housing costs plus other debt obligations.

This can include payments for:

  • Credit cards
  • Lines of credit
  • Car financing
  • Personal loans
  • Student loans
  • Other outstanding debts

This is why two borrowers with the same income may qualify for different mortgage amounts if their existing debt levels are different.

 

Credit Card Debt Can Affect Your Mortgage Application

Carrying a balance on your credit card can affect your mortgage application in more than one way.

Your credit utilization can also affect your credit profile. For example, consistently using a high percentage of your available credit may have an impact on your credit score.

If you're planning to apply for a mortgage, it's worth reviewing your credit card balances and payment obligations before submitting an application.

 

Car Loans and Leases Can Reduce Your Borrowing Capacity

A car payment may seem unrelated to buying a home, but it can have an impact on your mortgage qualification.

Suppose you have a significant monthly car payment. That payment is already taking a portion of your monthly income, which can reduce the amount of income available for a potential mortgage payment.

This doesn't necessarily mean you cannot qualify for a mortgage. It simply means your existing obligations are part of the overall picture lenders review.


Lines of Credit and Personal Loans

Lines of credit and personal loans can also affect your mortgage application.

Even if you aren't currently making large payments toward the balance, lenders may use specific calculations to determine the debt obligation associated with these accounts.

Before applying for a mortgage, make sure you understand the balances, limits and payment requirements associated with your credit facilities.

 

Does Having Debt Mean You Can't Get a Mortgage?

Not necessarily. Having debt is common, and many homeowners have mortgages while also carrying other forms of credit. At Brevity Capital, we work with a wide range of lenders to offer more flexibility and solutions for these situations.

The important factors include the amount of debt, required payments, your income, credit history and the overall strength of your application.

Someone with a higher income and manageable debt payments may have a very different borrowing capacity from someone with the same debt but a lower income.

Mortgage qualification is not simply about whether you have debt - it is about how your overall financial picture looks.

 

What If Your Debt Is Affecting Your Mortgage Approval?

If your existing debt is limiting your borrowing capacity, there may be different options to consider depending on your circumstances.

Pay Down Existing Debt

Reducing certain debts before applying for a mortgage may lower your monthly obligations and potentially improve your debt-service ratios.

However, it's important to consider your overall financial situation. Using most of your available savings to pay down debt could leave you with less money for your down payment, closing costs or emergency expenses.

Consider Debt Consolidation

For some homeowners, consolidating higher-interest debts through a mortgage refinance may be an option.

Depending on your circumstances and available home equity, refinancing may allow you to combine certain debts into a single financing arrangement.

Because refinancing can involve interest costs, penalties and other fees, it is important to review the overall numbers before proceeding.

Review Your Mortgage Options

Different lenders may have different lending policies and qualification guidelines.

If your application doesn't fit the requirements of one lender, another lender may have a different approach depending on your financial circumstances.

This is one reason working with a mortgage professional can be helpful when your financial situation is more complicated.

What About Bad Credit and High Debt?

A borrower may have a strong credit history but carry significant debt. Another borrower may have manageable debt but a history of missed payments or other credit challenges.

We’ll look at your complete application, including income, credit history, debt obligations, down payment and property details.

If you have credit challenges or significant debt, it is always worth a shot to review your situation with us rather than assuming you will automatically be declined.

 

How Can You Prepare Before Applying for a Mortgage?

Before applying, consider taking the following steps:

Review your debts: Know your outstanding balances, monthly payments and credit limits.

Check your credit: Review your credit report for accuracy and understand your current credit position.

Avoid taking on unnecessary new debt: Applying for new credit or financing before a mortgage application can affect your overall financial picture.

Organize your documents: Have your income, employment, debt and other financial documents ready.

Understand your budget: Don't focus only on the maximum mortgage amount you may qualify for. Consider what monthly payment fits comfortably within your overall budget.

Get professional advice: If you have multiple debts, self-employed income, credit challenges or other financial considerations, discuss your situation with the Brevity Capital team before applying.

 

The Bottom Line

Debt does not automatically prevent you from getting a mortgage. However, your existing debt payments can affect your debt-service ratios, borrowing capacity and overall mortgage qualification.

Understanding your financial position before applying can help you identify potential challenges and explore your options early.
