Home equity vs commercial property: which should secure your business loan?

Picture the same lender looking at two properties of equal market value: a four-bedroom house in a Brisbane suburb, and a small strata warehouse unit in an industrial estate twenty minutes away. On paper both are worth $1.2m. In the credit file they’re treated very differently, and that gap is the heart of this comparison.

What does a lender see in each?

The house is the asset lenders know best. There are thousands of comparable sales, plenty of buyers in any market, and valuers can price it quickly. Reserve Bank research has long noted that bank capital settings encourage lenders to ask for residential property as collateral, and its October 2025 bulletin found new loans secured on residential property are far larger, on average, than those secured by other assets.

The warehouse unit is valued on different logic. Its worth leans on the lease (remaining term, rent level and tenant quality), on zoning and on how easily it would sell if the lender ever needed to. A long lease to a solid, unrelated business supports the value. A vacant unit, or one leased to your own struggling business, supports far less. Our guide to how lenders value commercial property walks through the valuer’s checklist.

Side-by-side comparison

	Home equity	Commercial property
Share of value lenders will advance	Usually higher	Usually lower, and lower again for specialised buildings
Valuation	Often quick, sometimes a desktop or short inspection	Fuller report; lease, tenant and zoning reviewed
Speed to funds	Often fastest, especially by caveat	Can take longer while the valuation is completed
Who signs	Every owner on title, often including a spouse or partner	The owning entity; directors or trustees as guarantors
What’s at stake personally	The family home	A business asset, though guarantees may reach your home anyway
Rental income	None (unless investment)	Can support repayments if leased to a third party
Correlated risk	Separate from the business’s fortunes	High if your own business is the tenant
Ownership traps	Co-owners and existing mortgage terms	Trust or company ownership; SMSF property generally can’t be used

The questions that decide it

Who owns it?

Lenders need every registered owner to sign the mortgage or caveat documents. For a home held jointly with a partner, that makes the loan a household decision, and it should be. For commercial property, check the title: the owner might be a company, a discretionary trust or your SMSF. Company and trust property can usually be offered with the right resolutions and guarantees. SMSF property is different: super rules stop the trustee creating a charge over fund assets, so a fund-owned building generally can’t secure your business loan.

How exposed is it to your business?

Pledging the premises your own business trades from feels neat, but it concentrates the risk. If trade falls away, the business struggles to repay, and the building loses its paying tenant at the same moment. A home, by contrast, holds its value whatever the business does. That’s precisely why lenders like it, and why owners should think hard before using it.

What protections apply?

A loan secured on your home but used wholly or mainly for business is generally not regulated consumer credit, so the consumer-style protections attached to home loans don’t automatically carry across. It’s a reason to read the contract carefully, not a reason to panic. Our business loans against your home page covers the practical steps.

When does home equity win?

• You need the money quickly. Lending against a house, particularly by caveat loan, tends to settle soonest.
• The amount is large relative to what you own. A higher lending ratio squeezes more out of the same equity.
• Commercial property isn’t available or is in an SMSF or leased to a related party.
• It’s a short loan with a dated payout. A bridging need with a known repayment date limits how long the home is on the line.

When does commercial property win?

• You want the family home kept out. For many owners this is the deciding factor, and it’s a legitimate one.
• The property has a strong third-party lease. Rental income and a reliable tenant support both the value and the repayments.
• There’s plenty of equity. If the building is lightly geared, a lower lending ratio still leaves enough room.
• The loan is long-term. Tying a business asset to a multi-year business facility is often a better match than tying up the home for years.
• A co-owner of the home isn’t comfortable. Respecting that avoids a fraught signing and protects the relationship.

Run each property through the LVR calculator before you decide. The number that matters is usable equity at the lender’s ratio, not the market value.

Worked example

Illustrative only. Dan and Priya own their home worth $1.1m with $450k owing, and Dan’s company owns its workshop worth $900k with $200k owing. The company needs $300k to fund a new contract.

• Against the home: at a typical residential lending ratio, there’s comfortably enough usable equity for $300k, the valuation is quick, and funds could arrive within days. But Priya, who isn’t involved in the business, has to sign, and the family home carries the risk.
• Against the workshop: at a lower commercial ratio, the usable equity still covers $300k, though with less to spare. The valuer needs a few more days. Their home is untouched, but if the contract goes wrong the business and its premises are hit together.

Dan and Priya choose the workshop and accept a few extra days. Another couple, with a tight deadline and less commercial equity, might reasonably choose the home.

A short checklist

1. Whose names are on each title, and is everyone prepared to sign?
2. What’s the usable equity at the lender’s ratio for each property type?
3. Is the commercial property leased, and to whom?
4. Is either property held in an SMSF?
5. Does your existing first mortgage allow further security without consent?
6. What’s the repayment plan, and how many months will the property be committed?

Two properties, one conversation

Many of the owners we speak with have more than one possible security and aren’t sure which to put forward. Our own lenders HomeSec Business Finance and EquityTap both lend for business purposes against residential and commercial property, and our team can compare how each asset would be treated. Our form is a minute or so of your time, and asking the question doesn’t trigger a credit check. Nothing you send is circulated among other lenders. One of our team studies your details personally, then rings to talk through the trade-offs with you. Tell us accurately who owns what and what’s owing, so the first structure we suggest is one that will actually work.
