Negative equity occurs when the outstanding mortgage on a property exceeds the property’s current market value. In this situation, if the owner were to sell, the sale proceeds would not cover the full loan balance — leaving the owner with residual debt after settlement.
How negative equity occurs:
Property value decline. The most common cause. If a property is purchased at or near the peak of a market cycle and values subsequently fall materially, the loan balance may exceed the new market value.
High initial LVR. Buyers who purchase with a small deposit (e.g. 95% LVR) have minimal equity buffer. A relatively small decline in property values (5%) can result in negative equity for a 95% LVR borrower.
Interest-only loans. Borrowers on interest-only terms do not reduce their principal balance during the interest-only period. If values fall and the principal hasn’t reduced, the gap between debt and value is wider.
Off-the-plan purchases. If the valuation at settlement is lower than the purchase price, the buyer may effectively be in negative equity from day one.
Impact on investors. Negative equity does not immediately cause financial hardship if the investor can continue to service the loan. The problem arises when the investor needs to sell — either by choice or due to financial distress — and cannot cover the full loan from sale proceeds.
Risk management. Buying with a meaningful deposit (20% or more), selecting well-located investment-grade properties, and avoiding peak-of-market purchases reduces negative equity risk.
