Closing credit cards before applying for a mortgage: should you?

Closing credit cards before applying for a mortgage can help in some cases, but it is not a fixed rule, and the right move depends on your circumstances and lender criteria. What usually matters more to a lender is the credit limit on each card rather than the balance, because many lenders treat the full limit as money you could draw on. So the question is less about closing every card and more about whether your total limits, your repayment history, and your overall debts present a clear, low-risk picture when you apply. This guide walks through how cards affect a home loan, when reducing or closing a card may help, and the steps to do it safely.

If you want a straight answer for your own situation, the team at Finance Lab can look at your cards alongside your income and deposit and tell you what is likely to move the needle. You can also explore our home loans options to see where your cards fit in the wider picture.

How credit cards affect a home loan application

When you apply for a home loan, the lender reviews your financial position to decide how much they may lend. According to the Australian Securities and Investments Commission (ASIC) Moneysmart service, credit providers look at your credit history to decide whether to give you credit or lend you money, and a higher credit score means the lender will consider you less risky.

Your credit cards show up in two places that a lender cares about. The first is your borrowing capacity. Many lenders assess a credit card as an ongoing commitment based on its credit limit, not the current balance, because you could spend up to that limit at any time. That means a card with a high limit you rarely use can still reduce how much a lender is willing to advance. The exact way a lender converts a limit into a monthly commitment depends on their own criteria, so two lenders can reach different numbers from the same cards.

The second is your credit report. Moneysmart explains that your credit report lists, for each credit product you have held in the last two years, the type of product such as a credit card, the provider, the credit limit, and the account opening and closing dates. It also records your repayment history. The factors that affect your credit score include the amount borrowed, the number of credit applications you have made, and whether you make payments on time.

Paying off credit cards before a mortgage versus closing them

Paying off credit cards before a mortgage and closing them are two different things, and they help in different ways.

Paying a card down to a zero balance removes the debt and the interest, and it shows a clean repayment record. It does not, on its own, reduce the credit limit a lender counts against your borrowing capacity. The card is still open, so the limit is still there.

Closing a card removes the limit entirely, which can lift your assessed borrowing capacity if that limit was weighing it down. Moneysmart suggests that when you are managing multiple debts, it helps to prioritise reducing the number of cards you keep, and to cancel each card as you pay it off.

There is a middle path. You do not always have to close a card to reduce its effect. You can ask your provider to lower the credit limit instead, which keeps the card open but shrinks the commitment a lender counts. Moneysmart notes you can request a credit limit reduction online, by phone or in branch, and that it typically takes between one and two business days to process.

So which is right for you? It depends on whether the limit is genuinely holding back your borrowing, whether you rely on the card for cash flow or emergencies, and how close you are to applying. The team at Finance Lab can model both options against a target loan amount so you are not guessing.

How many credit cards is too many

There is no single number that makes someone unsuitable for a home loan, so “how many credit cards is too many” really means how much total limit and risk your cards add up to. A person with two cards and modest limits they pay off in full each month can look stronger to a lender than someone with one card carrying a high limit and a patchy repayment history.

What a lender adds up is the combined limit across every card, your repayment record, and whether recent applications suggest you have been chasing credit. Moneysmart points out that the number of credit applications you have made is one of the factors that affects your credit score, so opening several cards in a short period before you apply can work against you.

The practical test is simple. If a card earns its keep through rewards or genuine convenience and you clear it monthly, it may be worth keeping. If a card sits unused with a limit that quietly trims your borrowing power, reducing the limit or closing it before you apply may help. You can see how your numbers stack up with a quick estimate. How lenders work out your borrowing power

A clean credit picture before you apply

Lenders reward a tidy, predictable history. Moneysmart notes that paying by the due date helps you avoid extra interest or late fees and helps keep your credit score healthy. A missed payment, which Moneysmart defines as one not made within 14 days of the due date, is recorded on your report along with how it was resolved.

It is worth checking your own report before a lender does. You have a right to get a free copy of your credit report every 3 months, and it is sensible to get a copy at least once a year. Reviewing it early gives you time to fix errors and clear small debts. Keep in mind that more serious marks last a long time. A provider can list a default if the amount owed is $150 or more and certain conditions are met, and a default stays on your credit report for five years, or seven years in the case of a clearout.

The documents a lender asks for tie directly to the picture your cards paint, so it helps to have them ready before you start. The documents you need for a home loan application

Closing a credit card the right way

If you decide to close a card, doing it cleanly avoids missed payments and surprises. Moneysmart sets out the key steps. Before you cancel, redirect or stop any direct debits or regular payments coming out of the card, redeem any rewards points, and pay the balance down to zero, because the balance must be at $0 before the card can be cancelled.

To cancel, contact your provider, usually online or by phone. Only the primary cardholder can close the account. Afterwards, get written confirmation of the closure, check the final statement for any charges that landed after you asked to cancel, and destroy the card. Closing a card shortly before you apply is fine, but give yourself a little time so the closure is settled and reflected before a lender reviews your file. Common first home buyer mistakes to avoid

Talk it through before you decide

Closing cards is one lever among several, and it works best as part of a plan rather than a guess. Whether to close, reduce, or keep a card depends on your income, your deposit, the loan you are aiming for, and the criteria of the lender you approach.
