Negative Equity and Underwater Mortgages: When Your Property Is Worth Less

Negative equity occurs when your mortgage balance exceeds the property’s market value. You bought a $600,000 apartment with a $500,000 mortgage; property values fell 20%, and your apartment is now worth $480,000. Your mortgage ($500,000) exceeds your equity ($0, actually negative $20,000).

This is more common than most borrowers realize, especially in investment property markets where values fluctuate significantly. Market downturns, neighbourhood deterioration, structural issues, or simply overheated markets can trigger negative equity.

The immediate impact is refinancing difficulty. If you want to refinance to a lower rate, most lenders won’t help because you’re over 100% LVR. They’d be lending more than the property is worth. Some lenders will refinance existing mortgages into negative equity situations (because you’re an existing customer), but rates are punitive (often 0.5–1.5% higher than standard).

Selling while underwater is the primary challenge. If your apartment is worth $480,000 and you owe $500,000, selling triggers a $20,000 shortfall. You must inject $20,000 from personal savings to complete the sale, or you negotiate a short sale where the lender accepts a loss.

Short sales are rare and require lender approval. Lenders have no incentive to accept a loss; they’ll typically refuse unless you can demonstrate financial hardship (job loss, illness preventing payment). Even then, they prefer to hold the mortgage and wait for property value recovery rather than accept a loss.

Life gets complicated if you have multiple mortgages. A scenario: primary mortgage $500,000, second mortgage (from a home equity line of credit) $50,000, property worth $480,000. Both lenders are in negative equity. If you sell, you’re $70,000 short. The first lender might accept $480,000 and take the loss, but the second lender gets nothing. Second lenders rarely accept this; the first lender may need to guarantee the second lender’s loss or you need to negotiate a complex settlement.

Holding and waiting is the strategy most borrowers adopt. If you can service the debt and your property is expected to appreciate (e.g., new infrastructure planned, area gentrifying), holding the property until values recover is viable. This requires patience; recovery can take 5–10+ years.

Renting the property to cover the mortgage is a mitigation strategy for investment properties. If your apartment is negatively geared (rent less than mortgage repayment) and in negative equity, you’re in a tough spot. You’re paying the gap out-of-pocket and building no equity. However, if the property has recently become negatively geared due to market conditions rather than cashflow, renting it to stabilize position while waiting for value recovery makes sense.

Capital gains are still possible while underwater. If you bought at $600,000, it fell to $480,000 (negative equity), but then rose to $520,000, you’ve recovered somewhat but are still technically underwater. However, if it then rises to $650,000, your negative equity is gone and you have $150,000 equity again. Tax-wise, your capital gain is calculated from the original purchase price ($600,000), so a $650,000 sale would be a $50,000 gain (for capital gains tax purposes).

Negative equity affects your net worth and borrowing capacity. Lenders assessing your serviceability and ability to borrow for other purposes will see negative equity as a red flag, suggesting overleveraging or poor decision-making.

Walking away (defaulting intentionally) is an option some borrowers consider but it’s extremely costly. Your credit is destroyed for 5–7 years, you may face legal action from the lender, and if you later receive income or assets, the lender can pursue those. Walking away should only be considered if you face genuine financial hardship (unemployment, illness) and have no other options.
