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.
