Combining two incomes is the most common way Australian households get into the property market, and with borrowing capacity squeezed by four rate rises this year, it matters more than ever. A joint home loan can lift what you can borrow, but it also ties both borrowers to the full debt, links your credit histories in the application and changes what happens if circumstances change later. Understanding how lenders treat joint applications helps couples, friends and family members go in with clear expectations.
How Lenders Assess a Joint Application
Lenders assess a joint application as one household. Both applicants’ incomes are added together, along with both sets of living expenses, debts and dependants. A car loan, credit card limit or HECS debt held by either applicant counts against the combined borrowing capacity, even if the other person has none.
Credit histories are reviewed for both applicants too. A default or a pattern of missed payments on one person’s credit file can affect the outcome of the whole application, which is why it helps for both people to check their credit reports before applying.
Do Both People Need to Be Employed?
No. Lenders can approve a joint loan where one applicant has little or no income, provided the combined position supports the repayments. The other applicant’s income then carries the serviceability calculation, and the lender still counts both people’s expenses.
What Joint and Several Liability Means
Almost all joint home loans are written on a joint and several basis. Each borrower is legally responsible for the whole loan. If one person stops paying, the lender can seek the full repayment from the other.
This is the single most important point for anyone borrowing with a partner, friend or relative. Splitting the repayments informally between you does not change what the lender can ask of each borrower.
Borrowing Together vs Owning Together
The loan and the ownership of the property are related but separate. Most lenders require everyone on the property title to be a borrower or a guarantor on the loan. How you hold the title, and how each person’s share is recorded, is a legal question, and a solicitor or conveyancer can explain the options.
Where partners contribute different amounts to the deposit or repayments, many choose to document the arrangement in writing with legal advice, particularly when buying with friends or family.
Structuring a Joint Loan
A joint loan can be split into separate portions, for example part fixed and part variable, while still sitting under both names. Offset accounts can be held jointly so both people’s savings reduce the interest charged. Some couples keep personal accounts separate and contribute to a shared offset, which keeps day-to-day finances independent while both benefit from the interest saving.
If either applicant is self-employed, the lender will need their business financials as well as the other applicant’s payslips. Pairing a PAYG employee with a self-employed partner is common and generally workable, although it can narrow the choice of lenders whose policy suits both incomes.
First Home Buyer Schemes and Joint Applications
When couples apply for government support such as the 5% Deposit Scheme, both applicants generally need to meet the eligibility criteria, including being first home buyers or not having owned property in Australia within the required period. If one partner has owned property before, it can affect access to some schemes and state concessions, so checking eligibility early avoids surprises at application.
What Happens If Circumstances Change
If a relationship ends, the loan does not automatically change. Both borrowers remain liable for the full amount until the loan is repaid or the lender agrees to release one of them. To remove a borrower, the person keeping the property usually needs to refinance or apply to the lender to take over the loan, and they must show they can service it on their own income.
Property settlements between separating partners involve family law, so legal advice is needed on how the property and debt are divided. On the lending side, a broker can assess early whether one partner is likely to qualify on their own, which can shape the options available.
Life changes such as illness or the death of a borrower are also worth planning for. Insurance that covers loan repayments can protect the remaining borrower, and a financial adviser can help assess what level of cover suits the household.
Key Takeaways
- Lenders assess joint applications as one household, combining both applicants’ incomes, expenses and debts.
- Both applicants’ credit histories are reviewed, so one person’s credit issues can affect the joint application.
- Joint and several liability means each borrower is responsible for the whole loan, however the repayments are shared.
- Most lenders require everyone on the title to be a borrower or guarantor, while title ownership itself is a legal question.
- Both applicants generally need to meet eligibility rules for first home buyer schemes such as the 5% Deposit Scheme.
- Removing a borrower after a separation usually requires the remaining borrower to qualify on their own income.
