Refinancing with negative equity is harder than refinancing without it, but it is not impossible and the position is rarely as bad as it feels. Negative equity means you owe more than the lender’s current assessed value of the property.
Sydney’s correction has brought the term back into conversation for the first time in years.
The Reserve Bank’s October 2026 review puts the share of borrowers who owe more than their property is worth at under one per cent, which is worth holding on to before you assume you are in it.
Refinancing with negative equity turns on a comparison between two numbers: your loan balance, and what a lender’s valuer says the property is worth today. If the first exceeds the second, you have negative equity.
It is not a default, it is not a breach, and your current lender will not call in the loan because of it. Provided you keep making repayments, nothing happens at all.
It only becomes a practical problem at the moments that require a valuation: a refinance, an equity release, or a sale. That is the whole of the issue.
Most people who worry about it are not in it. An agent appraisal from 2023 and a lender valuation from 2026 produce different numbers, and the gap frightens people unnecessarily.
Refinancing with negative equity stalls because a new lender has no history with you. It cannot see your repayment record and has no relationship to protect, so it assesses the property on its own valuation and lends a percentage of that figure.
If your balance exceeds what the new lender will advance, there is no transaction. The gap would have to be covered in cash at settlement, which defeats the purpose of refinancing.
Your existing lender is in a different position entirely. It already holds the security, it can see that you have paid on time, and a repricing request often needs no new valuation.
Refinancing with negative equity leaves four routes, in the order worth trying them.
| Route | What it involves | When it fits |
|---|---|---|
| Ask your current lender to reprice | A phone call. No valuation, no application, no cost | The place to start. It is the only route that works regardless of your valuation |
| Pay down to a workable ratio | Extra repayments or a lump sum to bring the balance under what a new lender will advance | You have savings and the gap is modest |
| Wait and revalue | Repayments reduce the balance each month while the market does what it does | The gap is small and you are not in a hurry |
| Internal product switch | Move to a different product with the same lender rather than leaving | Your lender has a sharper product you are not on |
The first route is free, needs no valuation and is the one borrowers most often skip. See whether refinancing is worth it.
Even without true negative equity, a softened valuation can push you above eighty per cent of value. At that point a new lender requires lenders mortgage insurance again, and you would be paying a second premium on a loan you have already insured once.
Premiums are generally not transferable between lenders and are rarely refundable beyond a short window after settlement. That cost frequently wipes out the rate saving entirely.
This is why refinancing with negative equity, or anywhere near it, should start with an estimate of the likely valuation rather than with a rate comparison. See how the insurance works.
Refinancing with negative equity is the question people ask, but it is rarely the only one that matters. Two other moves run into the same valuation.
Releasing equity for a renovation, a deposit on a second property or a debt consolidation needs headroom between the balance and the value. With no headroom there is nothing to release, regardless of your income.
Selling is the harder one. If the sale price does not clear the loan, the shortfall remains your debt after settlement, and agent and legal costs come off the proceeds first.
That is why refinancing with negative equity and selling are usually considered together rather than separately. Staying put while the balance reduces is often the least expensive of the three, though that turns on your own figures.
If a sale is unavoidable, speak to your lender early. Hardship arrangements exist, they are confidential, and asking about one does not trigger any action against you. See why applications are declined.
Two forces work in your favour at the same time, and together they shrink refinancing with negative equity as a constraint. Every principal and interest repayment reduces the balance, and the market does what markets do.
Extra repayments accelerate the first substantially, because they come off the principal directly. Even a modest amount each month moves the ratio faster than most borrowers expect.
When the numbers suggest you are close to a better tier, order a fresh valuation. The saving is twofold: better pricing, and the removal of the constraint on any future borrowing.

Possibly, depending on how far the balance sits relative to the new lender’s valuation. If you remain under eighty per cent of the assessed value, a refinance is usually available, subject to the lender’s assessment.
Between eighty and ninety five per cent it is possible but brings lenders mortgage insurance back into the picture. Above the valuation entirely, a switch to a new lender is generally not available.
Nothing, provided you keep making repayments. It is not a default and your lender will not call in the loan because the valuation moved.
It constrains you only when you need a valuation, which means refinancing, releasing equity or selling. Many borrowers pass through periods of negative equity without ever being affected by it.
Ask for the valuation basis and check the comparable sales used, because errors do occur and can sometimes be challenged with evidence.
Beyond that, try a different lender, since valuers and methods differ and a second opinion can land higher. If the valuation is simply accurate, your current lender becomes the better route because it needs no new valuation to reprice you.
Usually yes. Premiums are generally not transferable between lenders and are rarely refundable beyond a short period after settlement. Paying a second premium commonly eliminates the rate saving that motivated the switch, which is why the likely valuation should be estimated before any rate comparison is made.
Often, yes, and that is a legitimate outcome rather than a failure. Your existing lender already holds the security and can reprice without a new valuation, which removes the valuation obstacle.
A repricing request costs nothing, takes a phone call, and frequently closes much of the gap to the market rate you were chasing.
It depends on the size of the gap, your repayment type and what the market does. Principal and interest repayments chip away at the balance every month, and extra repayments accelerate it considerably because they reduce principal directly.
Many borrowers find the position resolves faster than they expected once they stop watching the market and start reducing the balance.
The Reserve Bank publishes its assessment of household balance sheets and negative equity in the Reserve Bank’s Financial Stability Review. Your own position should be confirmed with your lender.
