Real‑World Case Studies: Asset Protection vs Borrowing Power

If you’re a business owner or investor, choosing how to own your home is usually a trade‑off: more asset protection usually means less borrowing power and more tax complexity. For most Australians, buying the home personally gives stronger borrowing capacity and better tax outcomes, while using a company or trust can add protection but at a real cost in dollars and options.

This guide walks through practical case studies so you can see how the trade‑offs play out – in loan size, repayments, tax and risk – before you sign a contract or restructure your affairs.

Different ownership structures change both asset protection and borrowing power.

1. The core trade‑off: protection vs capacity in plain English

Before we dive into examples, it helps to frame the decision clearly.

1. Borrowing power is what a lender will safely advance you today, after applying APRA’s ~3% serviceability buffer and their own rules on income, debts and dependants (HEM benchmarks, etc.). For business owners, policies around company/trust income and guarantees matter a lot.
2. Asset protection is how hard it is for a creditor, liquidator or trustee in bankruptcy to get to your home if something goes wrong in your business or personal life.
3. Ownership structure (personal, trust, company, SMSF) changes both: it affects what lenders will do, and how far business or litigation risk can reach.

As explained in /insights/buying-home-personal-vs-company-vs-trust-australia, for 80–90% of households the “optimal” point is:

• Home owned personally, often in the lower‑risk spouse’s name; and
• Business risk ring‑fenced inside entities, with good insurance and conservative gearing.

The case studies below show why.

2. Case study 1 – Solo consultant choosing between personal vs family trust

Profile

• Maria, 42, IT consultant in Sydney, trading via a discretionary family trust.
• Trust profit (after expenses) averages $260,000 p.a.
• No staff, low overheads, professional indemnity and public liability cover in place.
• Target home price $1.6m, deposit $400,000 (25%).

She’s weighing personal ownership vs having the trust own the home.

2.1 Option A – Own the home personally

Lending treatment

• Lender uses Maria’s distributions from the trust as her income.
• They average the last two years’ taxable distributions and apply a shading factor.
• Serviceability assessed at actual rate + 3% in line with APRA expectations.

Indicative numbers (rounded):

• Distributions to Maria (2‑yr average): $240,000.
• Other debts: $20,000 credit card limit – lender assumes ~3% p.m. on the limit.
• Living expenses: benchmarked using HEM plus her disclosure.

After applying buffers, a mainstream lender might support a loan of around $1.2m–$1.3m in her personal name.

On a $1.2m loan at 6.0% P&I over 30 years:

• Monthly repayment ≈ $7,196.
• Serviceability tested around 9.0%, i.e. ≈ $9,655/month in their model.

Asset protection

• Maria is the at‑risk person. If she is sued personally for negligence and the cover fails or is inadequate, a judgment creditor can potentially access the home.
• If she has a spouse not involved in the business, putting the home in that spouse’s name (with their own income) could help, but that’s not her situation.

Tax and cost

• Full main residence CGT exemption if she lives there as her home.
• No land tax on the principal place of residence (PPR) in NSW up to high thresholds.
• Straightforward record‑keeping and refinance options.

2.2 Option B – Family trust owns the home

Now assume Maria’s accountant suggests the family trust buys the home, arguing that if Maria is sued, the home is further away from her personal creditors.

Lending treatment

The trust is the borrower and owner. Key points:

• Most mainstream lenders treat trust‑owned homes as higher risk.
• Some will not lend at all if the security is a PPR in a trust.
• Those that do may:
  • Cap the LVR at 70–80% instead of 95%.
  • Require full personal guarantees from Maria (and possibly adult beneficiaries).
  • Use tighter assessment rates or reduced income recognition.

In practice, Maria may only be able to borrow $900k–$1m in the trust, even though her underlying income hasn’t changed.

On a $1m loan at 6.25% P&I over 30 years (entity pricing is often slightly higher):

• Monthly repayment ≈ $6,156.
• Serviceability tested around 9.25%, ≈ $8,144/month in their model.

Borrowing power impact

• Capacity drops by roughly 20–25% purely due to structure and policy.
• She either:
  • Lowers her price point (e.g. from $1.6m to $1.4m); or
  • Tips in more cash and keeps a smaller buffer.

Asset protection reality

• Lender wants personal guarantees from Maria. As set out in /insights/lending-reality-buying-home-through-entity, this undoes a big chunk of the protection she thought she was buying.
• If the trust defaults, the bank can:
  1. Enforce over the house; and
  2. Pursue Maria personally for any shortfall (because of the guarantee).

This narrows the gap between personal and trust ownership more than many people expect.

Tax and cost

• The main residence CGT exemption usually does not apply to a trust‑owned home.
• Land tax may apply from dollar one, depending on the State and trust type.
• Higher accounting and legal costs each year to manage the trust.

2.3 Summary for Maria

For Maria, personal ownership almost always wins unless her risk is extreme and she has significant wealth outside the home.

3. Case study 2 – Tradie couple with high business risk

Profile

• Ben (builder) and Emma (nurse) in Brisbane.
• Ben operates via a trading company, turnover $2.4m, profit to family $260k.
• Emma on PAYG salary $120k.
• Two kids, existing investment property with $450k loan.
• Target home $1.4m, deposit $300k.

Their lawyer suggests: “Buy the home in Emma’s name only” for protection.

3.1 Option A – Joint ownership, joint borrowers

Income recognised for lending

• Emma’s salary: $120k.
• Ben’s company pays him $110k wage + $70k franked dividends.
• Lender averages last two years of distributions and wages.

Indicative combined income used: say $280k after shading.

Existing debts:

• Investment loan: $450k at 6.3% IO (assessed around 9.3% P&I).
• Two credit cards: $15k limits each – assessed ~3% of combined limit per month.

With both incomes and debts factored in, they might be able to borrow around $1.1m–$1.2m, comfortably funding a $1.1m loan.

At $1.1m, 6% P&I over 30 years:

• Monthly repayment ≈ $6,596.

Asset protection

• If Ben’s company collapses and he gave personal guarantees for trade suppliers or equipment, his share of the home is fully exposed to creditors.
• Emma’s share might be partially protected, depending on how the judgment and bankruptcy unfold.

3.2 Option B – Home owned 100% by low‑risk spouse (Emma)

They consider putting the title solely in Emma’s name, with Emma as the only borrower on the home loan.

Lending treatment

• Some lenders will still take Ben’s income into account to support living expenses, even if he’s not on the mortgage.
• But many will limit borrowing to what Emma alone can service because:
  • They’re not comfortable relying heavily on income from someone not legally liable for the debt; and
  • It complicates enforcement.

Assume a conservative lender view: they rely mainly on Emma’s $120k salary.

Indicative borrowing power:

• On that income, with two kids and existing investment loan still in joint names, Emma alone might only support $700k–$800k of home debt.
• That knocks their purchase budget back from $1.4m to around $1.0m–$1.1m, unless they reduce other debts or increase cash.

Asset protection upside

• If Ben’s business fails and he becomes bankrupt, creditors may struggle to reach the home if:
  • Emma funded the purchase from her income / savings; and
  • There is clear evidence Ben did not contribute significantly.
• Transfers at undervalue and sham arrangements can be unwound, so this must be done properly and early, with legal advice.

3.3 Practical middle ground

For many couples, the pragmatic answer is:

• Home in low‑risk spouse’s name, but
• Both incomes carefully modelled across lenders to find policies that:
  • Recognise the business income; and
  • Still allow legal structuring around title and guarantees.

This is where the detailed work in /insights/borrowing-capacity-small-business-owner-home-loan becomes critical – lenders differ widely in how they treat self‑employed income, existing investment debt and credit card limits.

4. Case study 3 – Investor couple eyeing a company structure under new tax rules

Profile

• Priya and Arjun, both engineers in Melbourne.
• Combined PAYG income $420k.
• Own PPR, loan $900k.
• Considering a $1.8m upgrade home and converting current home to an investment.
• Accountant proposes buying the new home in a company for asset protection and potential future gearing flexibility.

4.1 What’s changed in the tax landscape?

Recent and proposed changes to negative gearing and CGT (from 2026–27 Federal Budget measures and the 2026 Tax Reform Bill) tilt the scales:

• Negative gearing concessions on established properties are set to be heavily restricted for purchases after 12 May 2026.
• The familiar 50% CGT discount for individuals and many trusts is proposed to be replaced with CPI indexation and a 30% minimum tax on most capital gains.
• Pre‑CGT assets are being brought into the net prospectively.

This pushes more investors to consider company structures for investments. But for the family home, different rules still apply – most notably the main residence exemption, which companies generally cannot access.

4.2 Numbers: personal vs company for the new home

Assumptions:

• New home price: $1.8m.
• Equity from sale of old home after paying out loan: $600k net.
• Required new home loan: $1.2m.

Option A – Buy new home personally

Lending treatment:

• Both incomes used, strong surplus after APRA 3% buffer.
• Existing PPR debt closed out; old property becomes an investment with new loan split.

Indicative outcome:

• Borrowing power comfortably covers $1.2m.
• They structure:
  • $1.2m owner‑occupied split for new home (non‑deductible interest initially).
  • Refinance old property with investment split, interest potentially deductible subject to use of funds.

Tax and protection:

• Full main residence CGT exemption on the new home.
• Exposure if they’re sued personally, but both are PAYG and relatively low‑risk.

Option B – Company buys the new home

Lending treatment:

• Company is borrower and owner; both Priya and Arjun provide personal guarantees and often are co‑borrowers.
• Many lenders refuse to lend against a company‑owned PPR.
• Those that do usually:
  • Cap LVR at 70–80%.
  • Require more documentation and sometimes higher rates.

With $600k cash, an 80% LVR cap means maximum purchase price:

• 80% of purchase price funded by loan ⇒ Loan = 0.8 × Price.
• They have $600k; if price is $1.8m, required loan is $1.2m (67% LVR, fine).
• The issue is not so much the deposit but policy and serviceability.

Capacity hit:

• Some lenders will treat the PPR debt as investment/commercial exposure, using higher assessment rates or different HEM assumptions.
• This can shave 10–20% off the maximum loan, even before tax differences.

Tax and protection:

• No main residence CGT exemption in the company.
• Potentially higher land tax.
• Asset protection is better from non‑bank creditors, but:
  • The bank has the house as security; and
  • The bank also has personal guarantees, so their personal wealth is still on the hook.

Verdict:

• They give up a valuable long‑term CGT‑free gain on, say, the last $600k–$1m of growth.
• They face more complexity and a modest borrowing power hit.
• In return, they get marginal extra protection from other creditors, which may not be a big issue given their employment.

In practice, most high‑income PAYG couples in this position are better off with personal ownership and careful insurance, as also explored in /insights/structuring-premium-property-purchases-companies-trusts-smsfs.

Business risk, family goals and lender rules all shape the right ownership approach.

5. Case study 4 – Business owner with multiple entities and big goals

Profile

• Jason, 50, owns a chain of gyms via a holding company and several unit trusts.
• Group EBITDA around $1.1m, personal drawings $380k p.a. after tax.
• Married to Lisa (part‑time teacher, $50k p.a.).
• Already owns:
  • Family home worth $2.4m, loan $1.1m.
  • Two investment properties, loans totalling $1.6m.
• Wants to buy a $3.5m waterfront home and move in, keeping the existing PPR as an investment.

Their adviser suggests a “multi‑entity orchestration”: using personal, company and SMSF entities in stages.

This is exactly the type of strategy mapped in /insights/coordinating-personal-company-smsf-borrowing-premium-property-plan.

5.1 Constraints

• Lenders will apply at least a 3% buffer on all existing and new loans (owner‑occupier and investment) as per APRA guidance.
• Total debt already: $2.7m.
• New purchase requires at least $1.8m–$2.2m in additional borrowings depending on sale/equity release.

Jason is worried that owning the new home personally:

• Makes it available to any future liquidator or bankruptcy trustee.

He wants maximum protection, but also needs to preserve borrowing power to keep expanding the gym group.

5.2 A staged, blended approach

With coordinated tax, legal and lending advice, they might:

1. Refinance and restructure existing loans personally
   • Ring‑fence home vs investment debt with separate splits.
   • Optimise which loans sit in Jason vs Lisa’s names.
2. Use a company or trust for business premises only
   • Keep high‑risk commercial properties in an entity structure.
   • Keep the new PPR in Lisa’s personal name as the lower‑risk spouse.
3. Smooth personal guarantees
   • Where possible, limit Jason’s personal guarantees on newer business facilities.
   • Accept that for existing facilities, business debts with guarantees will still be treated as personal liabilities in mortgage serviceability tests.

5.3 What happens to borrowing power?

If Jason tried to buy the new $3.5m home directly in a company or trust:

• Many residential lenders would be uninterested or cap LVR harshly.
• He might be pushed into more expensive commercial‑style loans.
• Serviceability modelling would assume higher assessment rates on all his debts – home, investment and business.

Borrowing power could easily fall 30–40% relative to a carefully structured personal approach that maximises Lisa’s borrowing capacity and recognises Jason’s income more flexibly.

Whereas by:

• Keeping the new home in Lisa’s name;
• Ensuring Jason is not a co‑borrower on that loan; and
• Keeping business property and debt in entity structures;

…they can often achieve both:

• A high level of practical asset protection if the gyms fail; and
• More total borrowing capacity across personal, business and SMSF structures.

6. How to decide this week: a practical framework

These case studies show there is no one‑size answer, but there is a repeatable way to make a solid decision this week.

6.1 Step 1 – Rank your real risks

Ask bluntly:

1. How likely is it that my business or profession could generate claims beyond my insurance?
2. How leveraged is the business – and would a downturn trigger personal guarantees?
3. Am I likely to face family law risks (separation, blended families)?

For many PAYG professionals and low‑risk sole traders, the probability of losing the home because of work is low once you have good insurance and reasonable gearing.

6.2 Step 2 – Map your entities and guarantees

Write down:

• Every company, trust and SMSF you’re involved with.
• Every personal guarantee you’ve signed – bank, landlord, supplier, equipment.
• Which entities own which assets – homes, investments, business premises.

This list often reveals that personal guarantees already pierce the veil you thought you had. That’s why personal ownership of the home, with safeguarded borrowing power, often beats complex entity games.

6.3 Step 3 – Model borrowing power in 2–3 structures

Before you fall in love with a structure, ask your broker to model:

1. Personal ownership – home in your name or low‑risk spouse.
2. Trust or company ownership – realistically, with likely LVR and lender pool.
3. (Where relevant) Split approach – e.g. home personally, business premises in an entity.

For each, compare:

• Maximum loan size and repayments under APRA buffers.
• Likely interest rates (owner‑occupied vs investment vs commercial style).
• Lender appetite today and in future (refinancing, further borrowing).

If using generic calculators, remember the insight from /insights/borrowing-capacity-small-business-owner-home-loan: online tools can misstate self‑employed capacity by 20–40%, because they ignore averaging, add‑backs and business debts.

6.4 Step 4 – Layer in tax and estate planning

Once the borrowing power numbers are clear, then have your accountant and lawyer weigh in on:

• CGT outcomes on the family home vs investments.
• Land tax under each structure.
• Asset protection from non‑bank creditors (suppliers, litigants, ex‑employees).
• Estate planning – who you want to ultimately benefit from the home.

In most situations, the outcome is:

• Home personally owned (often in low‑risk spouse’s name), and
• Investment and business properties held in trusts, companies or SMSFs where they make sense.

Modelling lending, tax and legal outcomes side by side leads to better decisions.

7. One‑week action plan

Here’s how a busy business owner or investor can move from idea to decision this week.

Day 1–2 – Clarify goals and risks

• Write a one‑page summary: desired home price, timing, how long you expect to own it.
• List your business and personal risks, guarantees and existing debts.

Day 3–4 – Get borrowing power reality

• Collect last two years’ tax returns, notices of assessment and financials.
• Ask a CPA‑grade broker to model borrowing capacity in at least two structures:
  • Personal / spouse ownership.
  • Entity ownership (trust or company), if you’re seriously considering it.
• Stress test repayments at 2–3% above current rates and with lower business drawings for six months.

Day 5–7 – Tax and legal alignment

• Share the lending scenarios with your accountant and lawyer together.
• Ask three focused questions:
  1. “What do we really gain, in dollar terms, by using an entity for the home?”
  2. “How much borrowing power do we lose – and what does that do to our plan?”
  3. “Can we get 80% of the protection by structuring ownership and guarantees more smartly, while keeping the home in personal names?”

If the extra protection is marginal and the borrowing power hit is large, the answer is usually clear.

FAQs – Asset protection vs borrowing power in home structures

1. Does buying my home in a trust always protect it from business creditors?

No. A trust can add a layer of protection against some creditors, but most lenders providing the home loan will still require personal guarantees from you as director or controller. That means the bank can pursue your personal assets if the trust defaults. Other creditors may find it harder to reach the trust’s property, but transfers made to defeat creditors can be unwound by a court.

2. How much borrowing power do I usually lose by buying through a company or trust?

It varies, but for mainstream lenders the drop is often in the range of 20–40% compared with borrowing personally on the same income and debts. This comes from lower maximum LVRs, fewer lender options and commercial‑style assessment policies. Some households can offset this by contributing more cash equity, but they still sacrifice flexibility and future refinance options.

3. Is it safer to put the home in my spouse’s name instead of a trust?

For many business owners, using the lower‑risk spouse’s personal name can be a simpler, more flexible way to protect the home from business risk than using an entity. It keeps full access to the main residence CGT exemption and better borrowing power with most lenders. The key is ensuring the structuring is genuine and not a last‑minute transfer to defeat known or looming creditors.

4. How do the new negative gearing and CGT rules affect whether I use a trust or company?

The recent and proposed reforms mainly affect investment properties, restricting negative gearing on established dwellings and changing how capital gains are taxed. They make entity choices for investments more complex, but they don’t improve the tax position of a company‑ or trust‑owned family home. For your PPR, the main residence exemption available to individuals usually still outweighs any theoretical tax benefits of entity ownership.

5. Can I change ownership of my home later if my risk profile changes?

You can, but transferring a home between you, your spouse, a trust or a company often triggers stamp duty and potentially capital gains tax. Lenders may also require a new loan application, with full serviceability checks under current rules. Because of these costs and risks, it’s preferable to choose a durable structure up front rather than relying on future transfers.

6. What professionals should be involved before I decide on a structure?

You ideally want a broker who understands both residential and business lending, a tax adviser with property experience, and a lawyer who handles asset protection and estate planning. They should look at the same numbers together – income, debts, entity diagram and proposed purchase – so you’re not getting conflicting advice. A one‑hour joint discussion can prevent years of complexity and regret.

Key takeaways

• Using a trust or company to own your home usually reduces borrowing power and lender choice, often by 20–40%.
• Personal guarantees often undo much of the asset‑protection benefit of entity ownership for the family home.
• For most households, personal ownership, often in the lower‑risk spouse’s name, balances protection, tax and borrowing capacity best.
• Entity structures are more often suitable for business premises and investments, not the main residence.
• The right structure depends on your real risk profile, guarantees and long‑term goals, not just tax theory.
