Quick answer

Property equity links to secured business lending: the difference between what a property is worth and what's owed on it can be used as security for a business loan. Lenders look at the loan-to-value ratio across all debts on the property, the type of property and the exit plan. Property-secured business loans run from $20,000 to $5,000,000 using first mortgages, second mortgages or caveats over residential or commercial property.

Key points

  • Equity = property value minus everything owed against it.
  • Lenders cap total borrowing as a share of value — the loan-to-value ratio (LVR).
  • First mortgage, second mortgage or caveat — the position affects terms and speed.
  • Security can help when trading history, credit or ATO position would limit unsecured options.

Some loan files are built mostly on trading figures. Others are built mostly on property. When a business owner — or the business itself — owns real estate with equity in it, that equity can change what’s possible: larger amounts, longer terms, and more flexibility around credit history or ATO debt. This page explains how property equity links to secured business lending and what lenders need to see.

What equity actually means

Business.gov.au describes assets as things you own, including property, and notes that debt finance often requires collateral. Equity in a property is simply:

Property value − all debts secured against it = equity

If a property is worth $1,200,000 and has a $500,000 mortgage, the equity is $700,000. A lender won’t lend against all of it, but some can be used to secure business borrowing. (Figures are illustrative.)

How lenders size secured loans: the LVR

The loan-to-value ratio (LVR) is the total of all loans secured on the property divided by its value. Each lender sets a maximum LVR depending on:

  • Property type — residential, commercial, industrial, vacant land, rural
  • Location — metro, regional or remote
  • Loan position — first mortgage, second mortgage or caveat
  • The borrower’s overall situation — trading, credit, exit plan
Example (illustrative)Figure
Property value$1,200,000
Existing first mortgage$500,000
New business loan$250,000
Total secured debt$750,000
Combined LVR62.5 per cent

If the lender’s maximum combined LVR for that property and position is above the combined figure, there’s room. If not, the amount may need to be reduced or another property added.

First mortgage, second mortgage or caveat?

PositionHow it worksTypically suits
First mortgageThe business loan is the only (or first) registered mortgageUnencumbered property, larger or longer loans
Second mortgageRegistered behind an existing home or commercial loanOwners who want to keep their existing first mortgage
CaveatA notice on the title recording the lender’s interestShort-term needs where speed matters

Across all three positions, secured business lending spans $20k to $5m, whether the property is a house, a unit or a commercial building. The funds must be used for business purposes.

When property security helps most

Secured lending often suits owners when:

  • The amount needed is larger than unsecured cash flow lending would provide (typically up to around $500,000)
  • The business is young or has limited trading history
  • There’s an ATO debt or past credit issue that limits unsecured options — both considered case by case
  • A longer term is needed to keep repayments manageable
  • The need is time-sensitive and the property position is clear

Documents lenders need for the property

  • Rates notice or title search confirming ownership
  • Current mortgage statement showing the balance and lender
  • Property details — address, type, approximate value
  • Owners’ ID, since property owners will usually sign the mortgage and a guarantee
  • Insurance details once approved

The lender will normally arrange a valuation. If the property is held in a trust or company, see company and trust documents.

The exit: how the loan gets repaid

For secured lending — especially shorter-term second mortgages and caveats — lenders focus on the exit: how the loan will be repaid. Common exits include:

  • Ongoing trading income, for longer-term facilities
  • Refinance to a bank once the business’s position improves
  • Sale of a property or asset
  • Receipt of a known payment, such as a contract settlement

A clear, realistic exit is often as important as the equity itself.

What affects how a lender values your property

The lender’s valuer looks at the property as security, which isn’t always the same as what you’d expect to sell it for. Factors that commonly matter:

  • Property type and use — a standard house or strata unit is usually easier to value and lend against than specialised commercial or rural property
  • Location and market depth — properties in areas with plenty of comparable sales tend to support higher LVRs
  • Condition — significant repairs needed can reduce the figure
  • Zoning and occupancy — tenanted commercial property is assessed partly on the lease
  • Recent sales evidence — the valuer relies on comparable transactions, not online estimates

If you expect a particular figure, it helps to share recent comparable sales or an agent’s appraisal with the specialist, though the lender’s valuation is what counts.

An illustrative example

A hypothetical building-supplies business needs $350,000 to buy out a retiring partner. The remaining owner has a home worth around $1,400,000 with a $450,000 first mortgage, and wants to keep that mortgage with its current lender. A second mortgage for the buyout brings total secured debt to $800,000 — a combined LVR of about 57 per cent — with the business’s trading income as the repayment source and the owner’s guarantee in place. The figures are illustrative; actual limits depend on the lender and property.

Talk to your planner and accountant first

Using property — especially the family home — links your personal wealth to the business. Before you proceed, ask your financial planner how a mortgage and guarantee fit your household plan, and ask your accountant how the loan fits the business’s cash flow. Our owners’ page on financial planners and business borrowing covers those conversations.

See what your equity could support

If you or your business own property, it could open options that trading figures alone can’t. Start a 60-second enquiry and tell us roughly what the property is worth and what’s owed. There’s no credit check to ask, your details are matched to one suitable lender instead of being circulated, and a real specialist calls you to talk it through. Be as accurate as you can about the property and existing loans — it’s how we link you to the right lender first go. Check your secured options.

Frequently asked questions

How much equity do I need for a secured business loan?

It depends on the lender's maximum loan-to-value ratio for that property type and loan position. A lender adds the existing mortgage and the new loan together and compares the total with the property's value.

Can I use my home as security for a business loan?

Yes. Residential property, including the family home, can secure a business loan. The funds must be used for business purposes.

What's the difference between a second mortgage and a caveat?

A second mortgage is registered behind your existing first mortgage. A caveat is a notice on the title recording the lender's interest; caveat loans are generally used for shorter-term needs.

Do I need full financials if I offer property security?

Not always. Some secured products rely on the security and lighter income evidence, such as BAS, bank statements or an accountant's letter. Others still want full financials.

Does the property have to be in the business's name?

No. Property owned by directors or related parties is often used, with the owners providing a guarantee and mortgage.
