Yes it may still be possible to get a mortgage while you have existing debt. Lenders commonly assess borrowers with student loans, personal loans, car finance, credit cards or buy now pay later facilities. The issue is how those commitments affect affordability and the complete application, not simply whether a debt exists.
Existing debt is not automatically bad credit and does not automatically prevent mortgage approval. Its impact depends on the repayments, available credit limits and the borrower’s complete financial position.
If your main concern is missed payments, defaults or adverse information on your credit file, use the Mortgage With Bad Credit guide.
Platinum Mortgages reviews how each commitment affects borrowing capacity and whether reducing a balance, closing a credit limit, lowering the requested loan or choosing a different lender is more likely to improve the overall outcome.
Different types of debt can affect a mortgage application differently. The sections below explain how lenders commonly assess each type of commitment.
Many borrowers worry that simply having debt means they won’t qualify for a mortgage. In reality, lenders usually look at how those commitments affect affordability rather than whether debt exists at all.
“I Only Owe A Small Amount — Why Did It Matter?”
Even relatively small commitments can reduce borrowing capacity when combined with a mortgage. Credit cards, personal loans, car finance and Buy Now Pay Later facilities may all be included when a lender assesses affordability. Often it is the combined effect of several commitments rather than one large debt that changes the outcome.
“My Credit Card Hardly Has A Balance”
Many borrowers are surprised to learn that some lenders assess the available credit limit rather than just today’s balance. A card with a high unused limit can sometimes reduce borrowing capacity even if little or nothing is currently owing.
The lender considers the required repayments, unused credit limits, recent account conduct and the amount of income left after normal living costs. Its impact can vary depending on the repayment, remaining term, lender and the borrower’s wider financial position.
Ultimately, each lender considers existing debt within the context of the complete application, rather than assessing one commitment in isolation. Banks may also calculate how the borrower’s total debt compares with gross income under New Zealand debt-to-income requirements, alongside their normal affordability and servicing assessment.
Angela Downie, Financial Adviser, Platinum Mortgages explains:
“When someone tells me they already have debt, the first thing I want to understand is what type of debt they have. Are they referring to previous credit issues or defaults that appear on their credit report, or are they talking about existing lending such as credit cards, personal loans, car finance or a student loan?
Many borrowers assume the total amount they owe is the most important factor. In reality, I’m usually more interested in the repayments attached to that debt, because it’s those regular repayments that affect affordability and borrowing capacity. Once I understand the type of debt and the monthly commitments, I can start working out what impact it’s likely to have and whether there are opportunities to improve the application before it is submitted.”
Different types of debt affect a mortgage application in different ways. Some commitments mainly reduce the income available for mortgage repayments, while others may influence borrowing capacity because of how lenders assess ongoing financial commitments. Understanding how each type of debt is treated can help identify whether changes before applying are likely to make a meaningful difference.
Personal loans, car finance and other repayments reduce the income available for a mortgage. Lenders may still include a loan that is almost repaid until it is cleared, or until the lender accepts evidence that this is imminent. Paying it off can improve borrowing capacity, but it may also reduce the available deposit. Comparing both outcomes before making a decision can help borrowers preserve the strongest overall position rather than simply reducing debt unnecessarily.
Lenders may assess the available limit rather than only today’s balance, because the borrower could use the facility later. Reducing an unnecessary limit may improve borrowing capacity, but the effect depends on the lender and the complete application.
For a fuller explanation of how credit-card balances and limits may affect borrowing capacity, read our Credit Card Debt and Mortgage Borrowing Capacity guide.
Student-loan deductions reduce the income available for mortgage repayments. Review the borrower’s complete position because lender treatment varies.
These facilities can affect both affordability and the lender’s view of spending conduct. Multiple active facilities, repeated use or missed payments can create more concern than a small, well-managed commitment. Some lenders distinguish between occasional discretionary purchases and ongoing reliance on Buy Now Pay Later. Regular reliance on Buy Now Pay Later for everyday living costs may create greater concern.
If a facility will be fully repaid and closed before settlement, some lenders may take a different view, although policies vary.
| Debt or facility | Possible effect on mortgage borrowing |
|---|---|
| Credit card or overdraft | The available limit and assumed repayment may reduce borrowing capacity, even when the current balance is low. |
| Personal or car loan | The scheduled repayment reduces the income available for the mortgage until the debt is cleared or treated differently by the lender. |
| Student loan | Income-based deductions reduce the net income available for mortgage repayments. |
| Buy Now Pay Later | Active facilities and repayments may affect affordability and recent account conduct, particularly where several facilities are used. |
| Business debt or guarantees | These may affect personal affordability and the lender’s assessment of ongoing or contingent obligations. |
The next step depends on what the numbers show. Options may include reducing a limit, paying down a selected debt, waiting until a repayment ends, reducing the requested mortgage, strengthening the deposit or considering a lender whose servicing approach better fits the complete application.
Base the decision on careful calculations rather than assumptions. The best solution is not always paying off debt, it is choosing the option that produces the strongest overall lending position.
If the application was declined for broader reasons involving income type, credit history, lender policy or the property, use our Bank Said No page for the immediate next-step process.
Angela Downie says:
“One thing borrowers often worry about unnecessarily is simply having debt. I regularly speak to clients who apologise for having a car loan, a personal loan or a few credit cards because they assume those things automatically rule them out for a mortgage.
In reality, having debt doesn’t necessarily stop you from buying a home if the repayments are still affordable.
Rather than making assumptions, I compare different scenarios with my clients. I’ll show them what their borrowing capacity looks like if they keep their existing debt, then compare it with the outcome if some of that debt is reduced or repaid.
My job is to present the different options and recommend the one that’s best suited to each client’s individual circumstances.”
A specialist lender may use a different servicing policy from a main bank. This may provide another pathway where the application remains affordable but does not fit standard bank policy. Our Non Bank Lending page explains how specialist lending works and when it may be appropriate.
If the main goal is to combine several debts or reduce existing repayment pressure, use our Debt Consolidation page for that separate assessment. Securing unsecured debt against a home can change the risk and extend the repayment period, so compare total cost and alternatives.
Angela adds: “One of the things I look for is whether a client is managing their existing commitments consistently. Lenders gain confidence when repayments are made on time, accounts are kept in order and current debt is being managed responsibly before a mortgage application is submitted.”
Every borrower’s financial position is different and unique. Platinum Mortgages reviews your income, repayments, credit limits, account conduct, deposit or equity and property to identify the changes most likely to strengthen your borrowing position.
Should I pay off my car loan before applying?
It may improve servicing, but it can reduce the deposit. Compare both outcomes before moving the money.
Does an unused credit card affect borrowing?
It can, because some lenders assess the limit rather than only the current balance.
Is student debt treated like bad credit?
No. It is generally an affordability commitment, not adverse credit, although the repayment affects available income.
Can a non bank lender ignore my debt?
No. The lender still assesses affordability and commitments, even if the servicing model or policy differs.
Before applying again, Platinum Mortgages can help you understand how your existing debts may affect borrowing capacity and which next step appears most realistic. A confidential assessment can often identify opportunities to improve borrowing capacity before unnecessary credit enquiries or declined applications affect future options.
