Can you keep the house on one income after a separation?

Sometimes, if one income plus child support covers the whole loan at the lender’s test rate. Some lenders count child support received under a formal agreement, and a transfer between former partners under a settlement is generally exempt from NSW duty.

What was the situation?

A family on the porch of their home
  • The home is worth about $1.45 million with $520,000 owing.
  • The property settlement gives the staying parent the house in exchange for the $310,000 payment.
  • Child support of roughly $1,400 a month is registered and reliably paid.
  • The refinanced loan would be about $830,000, on one income.

What was the problem?

A family together in their backyard
  • Servicing $830,000 on $105,000 is demanding under any lender's buffered assessment.
  • The question that decides the file is what else counts as income: many lenders will assess registered, demonstrably-received child support, some fully, some partially, some only while the children are young.
  • Lender selection is not a detail here; it is the whole outcome, as our separation guide sets out.

What made it difficult?

Three pressure points. Serviceability: even with child support counted, the numbers are tight, and practical levers, term length, expense discipline, a small contribution from the settlement's other assets, all matter.

Sequencing: lenders want the settlement documented before approving the buyout refinance, but the numbers must be tested before the agreement is signed, or the parent may agree to a buyout no lender will fund.

And the emotional weight: this decision needs numbers precisely because everything else about it is not numerical.

What does a broker assess?

Full single-income serviceability at buffered rates, with and without the child support counted, across the lenders that accept it. The equity position, deep equity is what makes the file possible at all.

The duty exemption, confirmed through the solicitor, which saves genuine five-figure money on the transfer. And the real alternative, costed: what selling, splitting and rebuying elsewhere looks like, so the decision to keep the house is a choice rather than a reflex.

What are the lending considerations?

Files like this succeed on deep equity, formalised child support at a lender that counts it, and a settlement negotiated around fundable numbers. They fail when the buyout figure was agreed emotionally first and tested financially second.

A broker's most valuable contribution often happens before mediation, not after, and where the straight answer is "the house cannot be kept", hearing it early protects everyone, children included.

What can borrowers take from this?

Test the lending before you agree to the buyout, not after. Formalise child support if it needs to count. Use the duty exemption, it is real money, routinely missed.

And let the alternative be priced properly: keeping the house is sometimes the right answer and sometimes a financial anchor; only the numbers know which.

Common questions about separation buyout

How do I buy my ex-partner out of the home?

The loan is refinanced into your name for the existing debt plus the settlement amount, assessed on your income alone. Whether it services on one income is the first question, before any paperwork. Loans after separation has the sequence.

Is stamp duty payable on a buyout?

Often not: transfers between separating partners under a formal agreement or court order are commonly exempt from transfer duty in NSW. The legal documents drive the treatment, which is one reason to formalise the settlement properly.

What if my income alone is not quite enough?

Options include lenders with sharper assessment of your income type, restructuring other debts first, or in some cases a family guarantee. Timing the application after the settlement terms are documented also strengthens the file.
