Guarantor loans: the shortcut to Sunshine Coast property ownership—and the hidden costs first-home buyers need to know

Priced out of suburbs like Noosa Heads, where $2 million-plus is the norm, many first-home buyers on the Sunshine Coast are turning to guarantor loans as a workaround to deposit shortfalls. But before your parents or grandparents sign on the dotted line, it's worth understanding exactly what you're asking them to risk.

A guarantor loan allows you to borrow with a smaller deposit—often 5–10 per cent instead of 20 per cent—by having a family member pledge their own property or assets as security. For a young buyer eyeing an entry-level apartment in Maroochydore's emerging CBD precinct or a townhouse in Kawana Waters, the maths can feel irresistible. Instead of saving another $80,000 to $120,000 for a standard deposit on a $550,000 property, you can move now.

The upside is clear: faster entry to the market, and the peace of mind that comes with owning rather than renting. You'll also typically pay lenders' mortgage insurance (LMI) on the loan, which can add $15,000–$25,000 to your borrowing, but that's calculated into repayments rather than upfront.

The catch? Your guarantor's financial life becomes intertwined with yours. If you miss a payment, the bank comes after them first. If property values fall—not uncommon in regional Queensland during downturns—your guarantor could owe the bank more than the property is worth. They also can't easily access their equity or refinance their own home without lender approval. For parents in their 60s near retirement, this is a significant exposure.

Legally, guarantors need independent legal advice before signing, and most banks insist on it. The Sunshine Coast Law Society and local conveyancers can explain the fine print, but it's an added cost—typically $500–$1,500.

Who qualifies? Lenders want guarantors to be homeowners with substantial equity, usually 20 per cent or more. A parent who owns a property in Coolum Beach or Bribie Island, free and clear, is ideal. Some banks will accept guarantors with existing mortgages, but their serviceability assessment becomes stricter.

First-home buyer grants—currently up to $20,000 in Queensland for new properties—can reduce the gap, but many Sunshine Coast homes are established stock, which don't qualify.

The honest advice? Use a guarantor loan only if you have a genuine plan to remove them from the loan within five to ten years, either through deposit buildup or equity growth. It's a ladder, not a permanent arrangement. And guarantee nothing unless you're prepared to own the consequences.
