Quick answer

A property-secured business loan lends from $20,000 to $5,000,000 against residential or commercial property. A first mortgage ranks first and usually refinances existing lending; a second mortgage sits behind an existing lender. Funders focus on equity, the property and how you will repay. It can work with thin trading history, but the property is at risk.

Key points

  • Amounts range from $20,000 to $5,000,000, secured over residential or commercial property.
  • First mortgage: first claim on the property. Second mortgage: a claim behind an existing lender.
  • Equity and the repayment plan drive the answer more than trading history does.
  • Costs include establishment and legal items as well as ongoing cost; compare in dollars.

When a bank says no, or says yes too slowly, the next idea is often property. It is a well-established route: a loan secured by a mortgage over real estate, for business purposes, in amounts from $20,000 up to $5,000,000. It’s also one of the most misunderstood, partly because the first-versus-second-mortgage question trips people up.

What exactly is a property-secured business loan?

It’s a loan to a business, secured by a registered mortgage over property that you, or someone connected to the business, own. The property can be residential, such as your home or an investment, or commercial. If repayments aren’t made, the lender can ultimately enforce its security.

The loan is for business purposes only: stock, equipment, a contract, tax, growth, a settlement or a bridge between two events.

What is the difference between a first and a second mortgage?

It comes down to ranking, meaning who is paid first from the property if it has to be sold.

First mortgage Second mortgage
Ranking First claim on the property Behind an existing lender
Existing lending Usually paid out and replaced Stays in place
Typical use Larger amounts, clean refinance Top-up without touching a good existing loan
Funder’s risk Lower than a second Higher, because someone else is paid first
What you will notice One lender, one loan Two lenders, two loans

A funder’s willingness at second position depends on how much equity remains after the first lender, which is why equity is the first question asked.

What do funders look at?

  • Equity, meaning value less everything already owed against the property.
  • The property: type, location, condition and how readily it could be sold.
  • Your plan to repay: from trading, a sale, a refinance or a settlement due.
  • The business, including what it does and what the money is for.
  • Ownership: who is on the title and who needs to sign. A trust or company adds a layer of authority checks.

Because the property carries much of the risk, trading history, credit blemishes and ATO debt are considered case by case rather than ruling you out.

What do you need to hand over?

  1. Title details and current mortgage statements.
  2. Photo ID for owners and directors.
  3. Evidence of property ownership structure.
  4. A short explanation of the purpose and repayment plan.
  5. Basic business details: ABN or ACN, bank statements and recent BAS.

You don’t need a valuation to ask. Tell us about the property and the plan and a specialist will say whether the numbers look workable before anything is lodged.

What are the costs and risks?

The property is on the line. This is the heart of it. A funder with a registered mortgage can enforce it, so repayment confidence matters more than speed.

Costs go beyond the ongoing cost. Expect establishment, legal and valuation-style items, and possibly state-based charges depending on the documents and your state. State revenue offices, such as the State Revenue Office Victoria, publish what applies in their jurisdiction. Read state by state for where the differences show up.

The paperwork is heavier than for unsecured funding. More signatures, more checks, more steps.

Contract terms are worth reading. ASIC explains that small business loans on standard form contracts can fall under unfair contract term protections. That doesn’t replace reading the document carefully.

How long do these loans usually run?

The term depends on the structure and the purpose. Some property-secured business loans are short and built around a known exit, such as a sale, a settlement or a refinance. Others run longer and are repaid from trading. A short term keeps the total cost down but needs the exit to be dependable. A longer term lowers repayments but extends the period your property is at risk.

Ask what happens at the end. Is the loan repaid in full, can it be extended, and what does an extension cost? A plan that relies on an extension being granted is weaker than one that stands on its own.

What does the process feel like from the borrower’s side?

Typically: you enquire, a specialist talks to you and checks the numbers, the funder reviews the property and the business, you receive terms in writing, and legal documents follow. Property adds a few steps that unsecured funding does not have, such as confirming title, arranging signatures and registering the security. None of them are mysterious, but they are real, so build time for them into your plan rather than assuming a few days.

Be wary of anyone who promises certainty before they have seen the property, and equally of any process that pushes you to sign before you have read the terms.

When is a property-secured loan the wrong choice?

  • The purpose is a small, short-term gap that unsecured or invoice-backed funding could handle without risking property.
  • The repayment plan is vague. Security doesn’t repay the loan.
  • The property is already heavily mortgaged, leaving too little equity to be worth the cost.
  • You only need funds for a few days before a known settlement. A caveat loan may be the more natural fit.

Is property your best route?

If you hold equity and a clear repayment plan, it can be the route that works when others won’t. The enquiry takes about a minute and involves no credit check; your details are not sent to a long list of lenders; and a real person reads the answers and calls you. The more accurately you describe the property, what’s owed against it and the purpose, the better the match. See if you qualify.

Frequently asked questions

What is the difference between a first and a second mortgage?

A first mortgage gives the lender first claim on the property if things go wrong, and often replaces existing lending. A second mortgage ranks behind the first lender, so the first lender is paid before the second. Because of that ranking, the position affects risk and terms.

Do I need to refinance my existing mortgage?

Not always. If your current loan is working well, a second mortgage can add funding without disturbing it. In other cases refinancing into one first mortgage is simpler.

Can I borrow if my trading history is short?

Often, yes, because the property carries much of the risk. The funder still needs a believable plan to repay.

Do I need a valuation before enquiring?

No. You can enquire using your own estimate of value and the amounts owing. If you proceed, the funder will confirm the value its own way.

Is there a catch?

The property is at risk if repayments aren't met. Costs also tend to include set-up and legal items on top of ongoing cost, so compare offers in total dollars.
