Second mortgages can unlock the value in your existing property without disrupting your first mortgage — but how much can you actually borrow?


At Assurity Capital, we specialise in fast, flexible second mortgage solutions for borrowers across Australia. Whether you’re looking to fund a business, settle urgent debts, or cover a property deposit, this guide will help you understand how much you can borrow with a second mortgage — and how the process works.

What Is a Second Mortgage?

A second mortgage is a loan that’s secured by a property already subject to a first mortgage. Because it ranks second in priority, the risk to the lender is higher — which is why major banks rarely offer them.


That’s where private lenders like Assurity Capital come in. We work with borrowers who need urgent capital and may not qualify through traditional banks.


How Much Can I Borrow?

Your second mortgage limit is primarily based on your available equity and the combined Loan-to-Value Ratio (LVR) — that is, the total of your first and second mortgages as a percentage of your property’s value.


Example Scenario:

  • Property value: $1,000,000

  • Existing mortgage: $600,000

  • Max LVR (first + second): 75%

  • Max loan: $1,000,000 × 75% = $750,000

  • Available second mortgage: $750,000 − $600,000 = $150,000

Flexible, fast, asset-based lending

At Assurity Capital, we can arrange second mortgages up to 75% LVR, depending on property type, location, and strength of the deal.


Do I Need Income Documents?

Not necessarily.

We focus on the strength of your asset, not your payslips or tax returns. We often help self-employed borrowers, investors, and business owners who:


  • Don’t have up-to-date financials

  • Have impaired credit

  • Need urgent settlements

  • Require non-traditional structuring


What Properties Are Eligible?

We arrange second mortgages against:

  • Residential homes (owner-occupied or investment)

  • Commercial properties

  • Vacant land (case-by-case)

  • Development sites


We lend in most states and territories, including metro and select regional areas. Prime suburbs like Bondi, North Bondi, Vaucluse, Mosman, Brighton, Toorak and others are especially attractive to private lenders due to stable values.


What Can the Loan Be Used For?

Second mortgages are typically used for:

  • Business cash flow

  • ATO tax debts

  • Legal payouts or divorce settlements

  • Bridging finance

  • Paying out caveat loans

  • Refinancing existing private loans

  • Property investment or deposits


Is First Mortgagee Consent Required?

Sometimes — but not always.

Registered second mortgages usually require consent from the first mortgagee, but we can also arrange unregistered second mortgages that do not require formal consent, offering faster settlement when time is critical.


Fast Funding. No Valuation Required in Some Cases.

We can often issue indicative terms the same day and settle within 48–72 hours, especially when:


  • There’s clear equity

  • The borrower is cooperative

  • Legal and title access is fast

Valuations are not always required, depending on location and loan size.
