Quick answer

A second mortgage lender assesses business loans mainly on the property's equity, the purpose and the exit, so past credit problems such as defaults, late payments or a previous ATO issue are considered case by case rather than being automatic knock-outs. They can affect pricing and structure. What helps most is a comfortable combined LVR, a first mortgage kept up to date and a candid explanation of what happened.

Key points

  • Equity and exit carry more weight than credit score for a second mortgage.
  • Arrears on the first mortgage are the most serious credit issue for a second lender.
  • Explain the story behind the credit history, briefly and honestly.
  • No credit check is run when you first enquire.

Why does credit history matter less on a second mortgage?

A bank lending unsecured or on thin security has little to fall back on except your track record, so it leans heavily on credit scores. A second mortgage lender has the property. Its assessment starts with three questions:

  1. Is there enough equity above both loans?
  2. Is the money going to a genuine business purpose?
  3. How does the loan get repaid?

Credit history sits after those. It still matters, because it’s evidence of how you handle obligations, but it rarely decides a file on its own. That’s why past defaults, late payments and old ATO problems are considered case by case.

Which credit issues matter most, and least?

IssueHow a second lender usually sees it
Arrears on the first mortgageMost serious. The first lender could enforce, which puts the second lender at risk.
Recent unpaid defaultsNeeds explanation and usually a plan to clear them.
Paid defaults, older than a year or twoContext matters; often manageable.
Tax debt reported to credit bureausUnderstood; the ATO reports business tax debts of $100,000+ overdue by 90 days where owners aren’t engaging. Clearing it is often the purpose of the loan.
Many recent credit enquiriesWorth explaining; common when an owner has been shopping around.
Late utility or phone paymentsMinor in the context of a property-secured loan.

The single biggest thing you can do before applying is keep the first mortgage up to date. Even if other things have slipped, a clean first-loan history reassures a second lender.

How do you present a file with bad credit?

Keep the explanation short, factual and forward-looking:

  • What happened. “A major customer went into administration owing us $140,000 in 2024.”
  • What you did. “We paid suppliers first; two small accounts defaulted and have since been paid.”
  • What’s changed. “We now credit-check customers and cap exposure to any one account.”
  • What this loan does. “Clears the remaining tax debt so we can refinance with our bank next year.”

That paragraph does more for a file than any amount of paperwork. Our documents checklist covers the rest.

When you’re ready, share the basics with a specialist. There’s no credit check at the enquiry stage, so asking costs your file nothing.

How does bad credit change the structure?

Credit history tends to affect how a loan is structured more than whether it’s possible:

  • A lower combined LVR. A thicker buffer offsets higher credit risk. Test lower amounts in the equity and LVR calculator.
  • Pricing. Every loan is priced on its own facts; credit history is one of them.
  • Term and exit. Lenders may prefer a shorter term with a clear exit.
  • Use of funds. Paying out the debts that caused the problem, directly at settlement, can strengthen the file.

Which lenders consider bad credit second mortgages?

Mainly private and specialist lenders who assess on security and exit rather than scorecards. That’s a different world from the major banks, with different speed, pricing and flexibility. Our page on private second mortgage lenders explains how they differ and what to check.

Illustrative example: a file with scars

An electrical contractor has two paid defaults from 2024 and an ATO debt of $95,000 on a payment plan that slipped twice. The home is worth about $1,050,000 with $430,000 owing and repayments have never been missed. A $130,000 second mortgage clears the ATO debt and a supplier account, taking combined LVR to about 53%. The explanation is candid, the purpose is clear and the exit is a bank refinance once a year of clean conduct shows. The figures are illustrative.

Should you check your own credit file first?

It’s a good idea. You’re entitled to a free copy of your consumer credit report from the major credit reporting bodies, and reading it before you apply means nothing on it surprises you or the lender. Look for defaults you thought were settled, accounts you don’t recognise and enquiries you didn’t make. Errors can be corrected by contacting the credit reporting body or the provider that listed them.

If your business is a company, it has its own commercial credit file, separate from yours as a director. Both may be checked once you proceed, so it helps to know what each shows. Knowing your own history also makes the short explanation described above much easier to write, because you can match each entry to what actually happened.

What doesn’t work?

Some situations are very hard to finance, whatever the equity: undischarged bankruptcy, a property already subject to enforcement by the first lender, or a purpose that isn’t genuinely business. Undisclosed issues are the other deal-breaker. A problem the lender finds on its own raises more concern than the same problem explained upfront. If your business is in serious financial trouble, business.gov.au’s guidance and your accountant are good first stops.

A rough patch doesn’t define the file

We regularly work with owners whose credit history has a few marks on it, and we look at the property and the plan first. Enquiring takes about a minute, with no credit check when you first enquire.

Your details aren’t passed to a queue of lenders; one specialist reviews them and calls you back to talk frankly about what’s possible. Please be upfront on the form about any defaults, arrears or tax debt. Accurate answers mean we can go straight to lenders who’ll say yes, instead of learning the hard way which ones won’t.

Frequently asked questions

Can I get a second mortgage with a default on my credit file?

Often, yes. A default is considered case by case. A lender will want to know what it was, whether it's been paid and what's changed since. Equity and exit matter more.

Will enquiring hurt my credit score?

Not with us. There's no credit check when you first enquire. A credit check happens only once you decide to proceed with an application.

Does bad credit mean a lower maximum LVR?

It can. Lenders may want a thicker equity buffer to offset credit risk. The calculator on this site lets you test lower borrowing amounts.

What if I'm behind on my home loan?

Tell us straight away. First-mortgage arrears are the most important issue for a second lender, but a second mortgage that clears the arrears and resolves the underlying problem can sometimes be structured.

Can a bankrupt borrow on a second mortgage?

Undischarged bankruptcy generally rules out borrowing against property. After discharge, a file is assessed case by case.
