Debt consolidation

Consolidating credit cards into your mortgage

Moving card balances onto a mortgage lowers the repayment and changes the nature of the debt. Both of those things are true, and the second one deserves as much attention as the first.

A settled family home at dusk, the asset that stands behind a consolidated loan once card balances move onto the mortgage.

A card balance is not a loan balance

A credit card is revolving credit. There is no schedule, no end date, and no obligation to reduce the principal. The contract asks only for a minimum each month, and that minimum is usually calculated as a small percentage of the closing balance or a fixed floor, whichever is greater.

Because the minimum is a percentage of the balance, it falls as the balance falls. The payment shrinks at almost exactly the rate the debt does, which is why a balance left on minimums can run for a very long time. Your own statement carries a minimum repayment warning that tells you how long, using your actual balance. It is the single most useful number in this whole subject, and it is already printed for you.

A mortgage works the other way. It amortises. The repayment is fixed against a term, each payment contains principal, and the debt has a date on which it ends. Moving a balance from the first structure to the second is the real change here. The rate matters, but the structure matters more.

The same $30,000, under two different rules

The card line is not flat because the rate is high. It is flat because the required payment shrinks as the balance does. A scheduled loan has an end date built into it. A card has none, and never acquires one.

What actually changes at settlement

The same balance behaves differently depending on where it sits. General characteristics only, not a description of any specific product.
On the credit cardInside the mortgage
StructureRevolving. The minimum falls as the balance falls.Amortising. A scheduled repayment with an end date.
TermOpen-ended. You decide, month by month.Set at approval, commonly the remaining mortgage term.
SecurityUnsecured. The card itself puts no property at risk.Secured against your home.
Pricing basisPriced as an unsecured revolving facility.Priced as a secured mortgage facility.
If you spend on it againThe balance simply climbs back.You now carry the loan and a new card balance together.
Total interest over timeDepends entirely on how long you take.A longer term can cost more in total even at a lower rate.

Read the last row twice. It is the honest catch in every consolidation, and it is the reason a good broker talks about term before talking about rate.

Unsecured debt becomes secured debt

This is the trade. Card debt is unsecured, which means the issuer has no claim over your home unless it goes to court and obtains one. Once that balance is inside a mortgage, the house stands behind it directly.

The exchange at the centre of a consolidation, with a lower monthly repayment weighed against the family home standing behind the debt.
An issuer holding an unsecured balance has to go to court to reach the house. A mortgage lender does not, because the security is already in place. That is the whole difference, and it is worth naming out loud.

For most borrowers that is an acceptable exchange, because the alternative is a balance that never reduces and a repayment burden that is already straining the household. But it should be a decision, not a default. If income is unstable, or if the same spending pattern is likely to rebuild the balance, then securing the debt against the home increases what is at stake rather than reducing it.

Term is the part most people get wrong

Spread a card balance across the remaining decades of a mortgage and the monthly repayment on it becomes small. That is the relief people come for. It is also how a modest balance quietly becomes a long-term cost, because interest accrues for as long as the debt exists.

A short debt stretched across the long remaining life of a mortgage, where a small repayment turns into a long-lived cost.
Term usually does more to the total than rate does. A shorter split is the ordinary fix, and it is far easier to arrange at application than to retrofit after settlement.

Total interest on $30,000 of card debt, by term

The monthly figure roughly halves. The total interest more than quadruples. Term is doing all of that, not rate, which is why the split is worth asking for at application rather than admiring the repayment.

Illustrative projection only. The same assumed rate is applied to all three terms so that term is the only variable. Not a quote and not an offer of credit.

There are two straightforward ways to keep the benefit without the tail.

  1. 01Split the loan. Ask for the consolidated portion to sit in its own sub-account with a shorter term. It is visible, it is separately trackable, and it has its own finish line.
  2. 02Keep paying what you were paying. If the total across the cards was a certain amount each month, direct that same amount at the new loan. The repayment relief is available if you need it, and the debt clears far sooner if you do not.

Both approaches are ordinary requests. Not every lender offers unlimited splits, and some charge for additional sub-accounts, so it is worth raising at application rather than after settlement.

Closing the cards is usually a condition

Most lenders will not simply pay a card down. They require it closed, and they want evidence. A statement showing a nil balance is not the same as a closed account, and lenders know the difference.

There is a servicing reason behind the condition. In a credit assessment, a card is generally counted at its limit rather than its balance, with an assumed monthly commitment calculated as a percentage of that limit. An unused card with a large limit still consumes borrowing capacity. Closing it removes the assumed commitment and improves the numbers on the file.

Payout figure
The exact amount required to close an account on a nominated day, including interest to that date and any fees. It is not the balance printed on your last statement.
Closure authority
The form that cancels the account rather than clearing it. Lenders ask for it because a nil balance and a closed account are two different things.
Limit versus balance
In an assessment the card is generally counted at its limit, with a monthly commitment assumed from that limit. This is why an unused card still costs you borrowing capacity.
Direct payment at settlement
The lender or settlement agent pays the issuer rather than depositing funds with you, which is how the lender proves the loan it approved is the loan that settled.

In practice this is handled at settlement. The lender or the settlement agent pays the issuer the payout figure directly, and you sign a closure authority. Ask early what evidence your lender wants, because a missing closure letter is a common reason a file sits waiting in the last week.

What it looks like on your credit file

Australia runs comprehensive credit reporting. Your file shows the accounts you hold, the limits, and a rolling record of whether each monthly payment was made on time. Missed payments sit on that record for a period, and so do defaults and credit enquiries.

A consolidation touches the file in several places at once. There is a new enquiry, one new account, and several closed ones. In the short term the mix looks busy. Over the following year, a clean repayment history on one account generally reads better than a patchy history across five.

The file in the first month or two

  • A new credit enquiry, dated and visible to anyone who looks.
  • One account opening and several closing within days of each other.
  • An account mix that reads as busy, which is normal for a refinance and still needs explaining.
  • Any recent arrears or hardship information still sitting on the record.

The same file a year on

  • One account carrying an unbroken run of on-time repayments.
  • Closed accounts still listed for a period, but without limits consuming borrowing capacity.
  • The enquiry now older, with repayment history built behind it.
  • A picture that reads as a tidy balance sheet rather than five accounts under pressure.

If you have already entered a hardship arrangement with a card issuer, that is recorded as financial hardship information alongside the repayment history for a set period. It does not prevent a refinance, but it does need to be disclosed, and it shapes which lenders on the panel are worth approaching. Being upfront about it saves a decline.

Making it stick

  1. 01

    Count everything first

    Every card, every store card, every buy-now-pay-later account and every personal loan. Balances, limits and current repayments. Half a list produces half a solution.

  2. 02

    Decide which cards close and which do not

    Most people keep one card with a modest limit for emergencies and genuine online use. Decide the limit deliberately rather than accepting whatever the issuer offers.

  3. 03

    Set the repayment before the relief

    Work out what you can sustain, not the lowest number available. Set the direct debit at that figure from the first month, while the resolve is fresh.

  4. 04

    Give the surplus somewhere to go

    If the consolidated repayment is lower than what you were paying, redirect the difference into an offset account or extra repayments so it does not simply absorb into spending.

  5. 05

    Review it in twelve months

    Check the balance is genuinely reducing and that the cards have stayed closed. A quick annual review catches drift while it is still small.

FAQ

Questions people actually ask

If yours is not here, ask it. We would rather answer the awkward one early than have you find out later.

Will consolidating cards into my mortgage lower my repayments?
In most cases the combined monthly repayment falls, because a mortgage is priced and structured differently to a revolving card and the balance is spread over a longer term. The size of the change depends on your balances, your loan and the lender, and no broker can quote you a figure before the file is assessed.
Do I have to close all of my credit cards?
Usually the lender requires the cards being paid out to be closed, with evidence. Whether you can retain a separate card that is not part of the consolidation depends on the lender’s policy and on whether the retained limit still allows the loan to service.
Is it cheaper overall, or just cheaper each month?
Cheaper each month is close to certain. Cheaper overall depends on the term. Card debt cleared over a long mortgage term can cost more in total interest even at a much lower rate, which is why splitting the consolidated portion into a shorter sub-account is worth asking for.
Can I consolidate cards if I have missed payments recently?
Often yes, though recent arrears narrow the lender options and change how the file is presented. Repayment history sits on your credit file for a period, so it is better to disclose it at the start than to have it appear during assessment.
Does the money come to me or go straight to the card issuer?
Generally straight to the issuer. Lenders prefer to pay consolidated debts directly at settlement using a payout figure obtained close to the date, because it proves the funds went where the approval said they would.
What happens to my buy-now-pay-later accounts?
They are treated as credit commitments in the assessment and can usually be included in the consolidation. Lenders read transaction statements closely for them, so list them upfront rather than leaving them to be found.
