SYDNEY, Nov 5 (Reuters) – Property investment markets are seeing a sharp correction as house prices tumble, leaving guarantors of home loans exposed to losses of up to $50,000 per loan. The slump, driven by tighter credit and a slowdown in buyer sentiment, has triggered a wave of settlement disputes across New South Wales and Victoria.

Property Investment Risk Landscape

The downturn directly affects borrowers who used family members or investors as guarantors. According to the Australian Prudential Regulation Authority (APRA), guarantor‑backed loans now represent 18% of new home loan commitments, up from 12% in 2023. Industry veterans warn that the risk profile has shifted from “low‑probability” to “material” within twelve months.

• Q3 2026: Nationwide price decline of 6.2% confirmed by CoreLogic, settlement disputes rise 22%.

Impact on Loan Guarantees

Legal analysts note that guarantors are now “on the hook” for the shortfall between contract price and settlement value. Cases filed in the NSW Supreme Court show average settlement shortfalls of AU$45,000, with some exceeding AU$80,000. Banks have begun tightening eligibility, requiring higher equity buffers from guarantors.

Future Outlook and Official Statements

The Treasury’s housing task force warned that continued price pressure could swell guarantor liabilities to over AU$2 billion by mid‑2027. Mortgage lenders such as Westpac and ANZ announced plans to roll out “guarantor protection products” by early 2027. Consumer advocacy group CHOICE urges prospective guarantors to seek legal counsel and explore mortgage‑guarantee insurance.
