The Lending Trick That Lets You Keep Buying Properties (When the Bank Says No)

Every property investor hits the same wall. The bank says your borrowing capacity is exhausted. No more loans. Your portfolio is stuck at three or four properties and your wealth-building engine has stalled.

The frustration is real. You have properties generating rental income, equity building in every asset, and a strategy that works. But the bank's serviceability calculator says you cannot afford another mortgage.

There is a structural workaround that most brokers never mention. It involves trust structures and lender sequencing. It is not a loophole. It is not aggressive. It is a legitimate strategy used by sophisticated investors across Australia. And it can unlock hundreds of thousands of dollars in additional borrowing capacity.

Why borrowing capacity hits a wall

Banks assess your ability to service a new loan using a stress-test interest rate, typically 2 to 3 percentage points above the actual rate. If you are borrowing at 6 per cent, the bank assesses your serviceability at 8 to 9 per cent.

For each investment property you own, the bank counts the mortgage repayment at the stress-test rate against your income. It also counts only 80 per cent of your rental income as actual income, discounting for vacancy and expenses 1.

The result: after three or four properties, the cumulative mortgage burden at the stress-test rate exceeds your assessable income. The bank says no. Not because your properties are unprofitable. Not because you are a bad credit risk. But because their formula says the numbers do not work at hypothetical rates that may never materialise.

This is the fundamental absurdity of Australian lending regulation. An investor with four cash-flow-positive properties generating $3,000 per week in rent can be told they cannot afford a fifth property that would generate another $800 per week. The real-world numbers work perfectly. The regulatory formula does not.

"The wall is arithmetic, not character. Banks stress-test your existing loans two to three points above the actual rate and count only 80 per cent of your rent, so the third or fourth purchase fails on a calculator rather than on your repayment record." — Yan Zhu, Co-Founder & Chief Data Officer, PremiumRea

The trust structure solution

A family trust (discretionary trust) is a legal entity that holds assets on behalf of nominated beneficiaries. When you purchase a property through a trust, the loan is taken out in the trust's name, with you as guarantor.

Here is where it gets interesting. Different lenders treat trust-held properties differently in their serviceability assessments. Some lenders include all trust liabilities in your personal serviceability. Others do not. The lenders that exclude trust liabilities from personal assessment effectively give you a clean slate for borrowing 2.

The pattern investors describe to us: buy the first properties in personal names through mainstream lenders while personal capacity lasts, then, once that capacity is exhausted, look at whether a trust structure plus a lender that assesses trust liabilities differently opens further room. Which lenders assess trust liabilities which way is not something we can tell you — it changes constantly, and a broker holds the licence and sees the policies week to week.

The trust borrows the money. You guarantee the loan. But the loan does not appear on your personal serviceability calculation when you approach a different lender for your next personal loan.

This is not a secret and it is not a grey area — it is a structural feature of how different lenders assess risk. But the specifics change constantly, and matching a structure to a lender's current policy is a licensed broker's job, not ours. We introduce clients to independent brokers and take no referral fee from any of them. We are not licensed to give credit advice 3.

Lender sequencing: the order matters

Not all lenders are equal. Their serviceability models, their treatment of trust structures, and their appetite for investment lending vary significantly.

Broadly, the market sorts into tiers. Major banks generally price sharpest and assess most conservatively. Second-tier banks and mutuals sit a little higher on rate with more flexible servicing. Non-bank lenders price highest and assess most flexibly, often looking at each property on its own merits rather than at the size of your portfolio 4.

I am deliberately not naming lenders or quoting their policies. Rates, servicing calculators, rental-income shading and the treatment of trust liabilities all change without notice, and we hold no credit licence — anything we published here would be out of date and would be advice we are not permitted to give. What is worth knowing is that those four things are where lenders actually differ, so they are the four things to have a broker compare for you.

I want to be clear: the higher rates from second-tier and non-bank lenders are a real cost. A 1 per cent higher rate on a $700,000 loan adds $7,000 per year to your interest bill. This only makes sense if the property generates sufficient cash flow to absorb the additional cost and still remain viable.

This is why our investment thesis is built around high-yield properties. Across the 345 settlements we've published (January 2023 to September 2025), the median gross yield after works was 5.77% and 84% came in at 5% or above. At that kind of yield an extra 1 per cent of interest is absorbable. When your properties generate 2.5 per cent yield, even a 0.5 per cent rate increase pushes you deeper into negative territory 5.

Practical example: five properties on a $150,000 income

Let me walk through a realistic scenario.

Property 1: $650,000, personal loan with a major bank. Rent $550/week. Serviceability comfortable. Property 2: $700,000, personal loan. Rent $600/week. Serviceability tight but approved. Property 3: $680,000, personal loan. Rent $580/week. Personal serviceability exhausted.

At this point, the investor establishes a family trust.

Property 4: $650,000, second-tier lender via trust. Rent $800/week (post-renovation) — on the assumption that lender's policy at the time treats the three personal loans differently in a trust assessment. That is exactly the question a broker has to answer before you commit, not something to assume. Property 5: $600,000, non-bank lender via trust. Rent $750/week (post-renovation), assessed on the property's own merits.

Total portfolio: $3.28 million across five properties. Combined rent: $3,280/week or $170,560/year. The portfolio is cash-flow positive from property three onwards because the renovation-driven yield on properties four and five exceeds the higher interest rates 6.

Without trust structures and lender sequencing, this investor would be stuck at three properties. With them, they have five properties and a self-funding portfolio.

This is the kind of structural thinking that separates investors who keep buying from investors who plateau. It is not about finding cheaper properties or higher rents. It is about understanding the lending infrastructure and designing your acquisition sequence around it.

Consult a specialist investment mortgage broker, not a retail branch broker, before executing any trust-based lending strategy. The details matter, and getting them wrong can be expensive.
