Refinancing With High LVR When Your Property Value Has Fallen

When your property value drops and your loan-to-value ratio (LVR) rises, refinancing to a better deal can suddenly feel out of reach. In Australia, once your LVR climbs above roughly 80%, most lenders either charge lenders mortgage insurance (LMI) or simply say no to a refinance. But even if your LVR is high – or you are in negative equity – you still have options to improve your position over the next 6–24 months.

This guide breaks down what a value drop really means, when refinancing is still possible, and how to make smart decisions this week rather than reacting in panic.

When property values fall, your loan-to-value ratio automatically rises.

1. What falling values mean for your LVR and refinance options

Before you decide what to do, you need to understand the mechanics.

1.1 Key definitions in plain English

• Loan-to-value ratio (LVR): Your loan divided by your property value, expressed as a percentage.
• Equity: Property value minus your loan balance.
• Usable equity: The amount you can safely access without pushing your LVR beyond a target level, usually around 80% rather than using all equity (see /insights/equity-strategies-property-investors).
• Negative equity: When your loan is higher than your property’s market value.

When property prices fall, your LVR automatically rises even if you keep making repayments. A high LVR plus higher interest rates (the RBA cash rate is around 4.35% in mid‑2026) means:

1. Refinancing to a new lender is harder.
2. You may be stuck with your current bank’s pricing.
3. LMI and risk limits start to bite.

1.2 A simple example

• Original purchase price: $800,000
• Original loan: $720,000 (90% LVR, with LMI already paid)
• Current loan balance (after a few years): $690,000
• New bank valuation after a downturn: $750,000

New LVR = $690,000 ÷ $750,000 = 92%.

That 92% LVR is above common refinance comfort zones. Many lenders prefer ≤80% LVR for low‑cost refinances and may cap new lending around 90–95% with strict conditions. You are not automatically stuck, but your strategy has to be smarter.

2. Why high LVR makes refinancing hard (and when it is still possible)

2.1 How banks see high LVRs

Lenders view a high LVR as higher risk because there is less buffer if you cannot pay and they need to sell the property. When values fall, their risk rises even before you miss a repayment.

Common thresholds:

• ≤80% LVR: No LMI on standard loans; best pricing and strongest lender choice.
• 80–90% LVR: LMI usually applies; lender appetite varies.
• 90–95% LVR: Specialist territory; tighter credit policy, often owner‑occupied only.
• >95% LVR or negative equity: Usually no refinance available unless you are restructuring hardship or bringing in extra security.

For some property types (for example, small units under about 50 m² in suburbs like Rose Bay), lenders may cap LVRs around 70–80% even in normal markets, reducing your flexibility further (see /insights/rose-bay-property-types-lending-rules).

2.2 The APRA 3% serviceability buffer

Since 2021, APRA has generally required banks to assess most home loans using a 3% buffer above the actual interest rate. If your actual rate is 6%, the bank assesses your capacity to repay at 9%.

When you try to refinance at a high LVR:

• You must pass this tougher test at the new lender’s rate plus 3%.
• Your borrowing power might actually be lower than when you first got the loan.

This is why many borrowers are currently told they are ‘mortgage prisoners’ – stuck on a high rate because they cannot pass the serviceability test elsewhere.

2.3 LMI, LMI top‑ups and why that matters

If you originally borrowed above 80% LVR, you likely paid LMI. When you refinance now at another high LVR, the new lender will usually:

• Charge another full LMI premium, or
• Charge an LMI top‑up if you stay with the same lender and increase the loan.

This cost can easily run into tens of thousands of dollars on a big loan. That does not mean it is always wrong; it just means you need a very clear benefit and time horizon to justify it.

For investors and higher‑income households, a common strategy is to cap home LVRs below maximum bank limits – often 70–80% – to protect against volatility and interest rate shocks (see /insights/rose-bay-equity-investments-family-safety-buffers). When values have already fallen, you are living through the reason that rule exists.
