How do lenders decide how much equity you can use across several properties?

Plenty of business owners hold equity spread across a few properties: the home, a rental bought in their thirties, the premises the business trades from. Add up the market values, subtract the debts, and the total can look enormous. Then a lender comes back with a figure that’s much smaller, and it isn’t obvious why.

The gap isn’t arbitrary. Lenders follow a fairly consistent method, and once you see the steps you can predict the answer yourself, and often improve it by choosing which properties to offer and in what order.

Why isn’t usable equity just the total of all your equity?

Because a lender can’t treat several titles as one pool. Each property is recorded on its own title, with its own owners, its own debts and its own lenders. Titles Queensland notes that a current title search shows the owners and registered interests “including mortgages, easements, covenants, leases and caveats”. A new lender’s rights depend on what’s already on each of those titles.

On top of that, every property type has its own lending limit, and every existing debt counts. So the honest way to measure equity is title by title, then add up what’s left.

What are the steps a lender follows?

1. Assess each property’s worth. Location, type, condition, comparable sales and saleability. We assess value ourselves, with no sworn valuation.
2. Apply the limit for that property type. We lend up to 80% of value on residential security and up to 70% on commercial, lower on large acreage.
3. Subtract everything already secured on that title. Every mortgage, every caveat-backed loan, every line of credit.
4. Decide the position on that title. First mortgage if it’s debt-free or the existing lender is being repaid; second mortgage or caveat if the existing lender stays.
5. Add the headroom together. Only properties with positive headroom contribute.
6. Test the total against the exit. The loan has to be repayable from the sale, refinance or payment you’re relying on.
7. Set the release terms. How much must be paid to free each title if it’s sold first.

Steps 2 and 3 are where most of the difference between paper equity and usable equity comes from. Our page on how much equity you can use shows the single-property arithmetic in more detail.

How does the property mix change the answer?

Because each type carries its own limit, two owners with the same total equity can get very different results.

Property type	Lending limit	Effect on the total
Residential	Up to 80% of value	Contributes the largest share of its worth
Commercial	Up to 70% of value	Contributes a smaller share
Rural and large acreage	Lower than both	Assessed case by case
Vacant land	Assessed case by case	Depends on zoning, services and saleability

A portfolio weighted towards homes and units will usually unlock more per dollar of value than one weighted towards shops or farmland.

Does debt on one property reduce what another can support?

Not on its own. Each title’s headroom is worked out separately, so a heavily geared rental doesn’t shrink the headroom on a debt-free shop. The highly geared property simply contributes nothing and is usually left out of the security.

The exception is cross-collateralisation. If an existing bank holds several of your properties as security for all its loans, it looks at its whole pool before it will consent to anything or release a title. That can tie up equity that would otherwise be free. Our guide on freeing a cross-collateralised property explains the options.

Illustrative example: three properties, one loan

Illustrative only: a made-up business owner, round figures, and limits used for illustration.

A Brisbane landscaping business owner needs $700k to buy out a departing partner. She owns:

Property	Assessed worth	Owing	Limit applied	Maximum total debt	Headroom
Family home (residential)	$1,300,000	$750,000	80%	$1,040,000	$290,000
Rental unit (residential, debt-free)	$600,000	Nil	80%	$480,000	$480,000
Small retail shop (commercial)	$800,000	$520,000	70%	$560,000	$40,000

On paper she has $1.43m of equity. Applying each title’s limit and debts, the usable headroom is $810k. The shop adds only $40k, and offering it would bring a third title, a bank consent request and more signatures, so it’s left out.

The rental unit alone, as a first mortgage, covers $480k. A second mortgage over the home for the remaining $220k sits well within its $290k of headroom. Together, two titles support the $700k.

Finally, the exit is tested. She plans to sell the rental within a year and refinance the balance with her bank once the buyout settles. A sale of the unit would clear the first $480k comfortably, and the home’s second mortgage is small enough for the bank refinance to absorb. The loan works.

With interest capitalised, there’s nothing to pay for the first 6 months, and open terms mean she can repay the moment the unit sells, with no penalty. You can run your own mix through the secured borrowing calculator.

Why can the exit cap the loan below your equity?

Equity says how much security there is. The exit says how much can actually be repaid. If the plan is to sell one property, the loan should fit within what that sale will realistically clear after costs. If the plan is a bank refinance, the loan should fit within what the bank is likely to lend.

That’s why two owners with identical equity can be offered different amounts: one has a firm contract of sale, the other has a hope. A clear, documented exit is often what unlocks the full headroom. If you’d like an indicative figure for your own properties, the 60-second check is the quickest route.

Which property should take the first mortgage?

Where you have a choice, a few principles usually give the best result:

• The debt-free property goes first, because a first mortgage reaches the most of its worth and needs no one else’s consent.
• Residential before commercial, where the need allows, because of the higher limit.
• The property you plan to sell is often the best anchor, because its sale is the exit, and the release price can be set to match.
• The family home last, where another combination will do.

Each property still carries its own mortgage or caveat. Land Use Victoria describes a mortgage as the document that “sets out the terms and conditions of the loan”; with several titles, the loan documents should also spell out what must be paid to release each one. Our page on using multiple properties as security covers releases and signatures in more detail.

What should you gather before you ask?

For each property you’re considering:

• the address and the owner’s name (personal, company or trust);
• the latest statement for every loan secured on it;
• whether the existing lender holds any of your other properties too;
• leases and rent statements if it’s tenanted;
• your plan for that property during the loan: keep, sell or refinance.

Equity spread across a few titles? See if you qualify

Equity sitting in several properties is a strong position to borrow from, provided the structure is right. Getting the order of titles and positions right can be the difference between a loan that works and one that falls short.
