Buying your first home together? How do two incomes become one loan?

The lender adds both incomes and both sets of commitments, so two incomes lift borrowing power but each partner’s debts reduce it. Each of you is checked for first home buyer eligibility, and if one has owned property before, some schemes may not apply.

Paperwork and finances were never my strong suit. He has made this process as simple and dummy proof for me as humanly possible. This is not the first time I use a mortgage broker, however it was the easiest and most pleasant.

Two incomes, one assessment

  • A lender assessing a joint application does not run two separate sums and add them up.It combines your incomes, combines your commitments and living expenses, and works out the surplus available to service a loan.
  • That matters because a debt in one person's name reduces the household's capacity just as much as if it were in both.A car loan, a credit card limit or a HELP debt belonging to one of you comes off the joint figure. What a HECS debt costs your borrowing power.

Buying together is usually stronger

  • For most couples the maths works in their favour.Two incomes against one set of living expenses generally produces more capacity than either person has alone, often substantially more, and the deposit comes together faster.
  • The exception is where one person carries significant debt or a credit issue.Occasionally a single application on the stronger income is the better outcome, though it comes with its own consequences for ownership and eventual capacity. It is worth modelling both rather than assuming.

How do you own it?

There are two ways to hold a property jointly in New South Wales, and the difference is not cosmetic.

  • Joint tenants means you own the whole property together, in equal shares, and if one of you dies the other automatically takes full ownership. It is the usual choice for couples and it sits outside a will.
  • Tenants in common means you each own a defined share, which can be unequal, and each share can be left to whomever you choose. It suits people contributing different amounts, or who want their share to pass to someone other than the other owner.
  • Your conveyancer or solicitor sets this up at purchase. It is easy to decide at the time and awkward to change later, so it is worth an actual conversation rather than a default.

What does joint borrowing mean?

Joint borrowing means you are both liable for the whole debt, not half of it each.

If one of you cannot pay, the lender can pursue the other for the full amount, regardless of what you agreed between yourselves or what share of the title you hold.

Not married, or not yet

Lenders do not require you to be married, and de facto couples are assessed the same way. What lenders care about is whether you are financially interdependent, because that determines whether they assess you as one household or two.

If you keep entirely separate finances and are buying together as something closer to co-investors, that is a different structure again and worth saying so at the outset. The first home buyer checklist covers the sequence either way.

How Links helps

Work out what you can borrow together and, where it matters, what each of you could borrow alone, so the choice is made on numbers.

  • Flag the eligibility questions early, particularly where one of you has owned before, because that is the one that most often changes a budget late.
  • And match you to a lender whose treatment of both your incomes and both your commitments produces the best outcome. Start with your borrowing position.

Common questions about buying together

My partner has owned a home before. Can we still get the first home buyer benefits?

It depends on the specific scheme, and this is the detail most worth checking early. The NSW stamp duty concession generally requires all purchasers to meet the criteria, so one person's prior ownership can affect both.

Do we have to be married?

No. Lenders assess de facto couples the same way as married couples, and you can buy together without being either. Some scheme rules do use relationship definitions, so it is worth confirming those separately.

Does my partner's debt affect what we can borrow?

Yes, in full. A joint application combines both incomes and both sets of commitments, so a car loan, a credit card limit or a HELP debt in one name reduces the household's capacity exactly as if it were in both names.

Can we buy with only one of us on the loan?

Sometimes, and occasionally it is the better outcome, for example where one person has a credit issue or heavy existing debt. It is worth modelling both structures rather than assuming the joint one is automatically better.

Joint tenants or tenants in common?

Joint tenants means you own the whole property together and the survivor automatically takes full ownership, which is the common choice for couples. Unequal deposits are the usual reason to choose tenants in common.

Buying together adds a few questions of its own, and our first home buyer FAQ covers the broader ones most first home buyers face.
