The commercial pivot. When to move from residential to commercial.

The 4-property serviceability wall

Some investors find lender serviceability tests limit further borrowing after several properties; the point varies by income, debts and lender. Combined household income $250-350k. Existing loans on 3-4 residential IPs. Broker looks at the numbers and says: "You can service another $200k, maybe. Not enough for another property."

The reason isn't your actual serviceability. It's the stress test. Banks assess future loans against a notional rate 3% higher than actual, factor in shading of rental income, and stack the calc against your total liabilities. Lenders apply a stress-tested rate and shade rental income, so assessed capacity can differ from actual cash flow. Your broker confirms.

What most investors do when they hit the wall

1. Wait 18-24 months. Income rises, LVRs fall, capacity rebuilds. Passive but slow. Costs 2 years of compounding.
2. Aggressive P&I paydown on highest-rate loan. Works. Slow. Doesn't feel like progress.
3. Give up on scaling. Stop at 4. Reasonable outcome, not a failure.
4. Commercial pivot. A fourth option the model can test. Whether it uses residential capacity depends on the lender.

How a commercial purchase compares at the 4-property borrowing test

Some lenders assess a commercial purchase more on the property’s own income. Policies differ by lender and may still count the loan against you. Your broker confirms how a lender treats it.

In this example the model shows positive cash flow. Whether it affects residential borrowing depends on the lender. In this modelled example, residential capacity rebuilds over years 3 to 5 if income rises and LVRs fall as assumed; a broker confirms lending.

Factors that change the modelled commercial result

You don't have the deposit

Commercial LVR is 70%, not 80%. On a $650k property you need $195k cash. Plus stamp duty ($20k+), legals ($3k+), Building & Pest inspection ($400+). Real all-in: closer to $225k. Commercial lending typically uses a lower LVR than residential, so the cash required is higher. Your broker confirms what a lender allows and whether any equity release is available.

You don't have the buffer

Commercial vacancies last months, not weeks. If your tenant leaves at year 4, you carry outgoings solo for 6-9 months while re-leasing. In this example the model shows a 6 to 9 month vacancy costing $30-50k. Whether a buffer is enough is for you and your adviser.

Your goal is short-term capital growth

Commercial returns have historically been weighted more to income than to capital growth. If you're targeting equity growth by year 5, residential has historically recorded higher capital growth than commercial in many periods; past growth does not predict future growth. Commercial's compound value is in the yield, not the growth.

You don't have appetite for a new DD process

Commercial DD is materially different. WALE analysis, tenant covenant checks, lease review clauses, sector cycles, cap rate compression risk. If you're new to it, you're either learning a new skill for 6+ months or hiring a specialist commercial buyers agent. Neither is fast. Both cost money.

Structure questions

Whether to hold a commercial property personally, in a company, in a trust or through a self-managed super fund is a question for your accountant and a licensed financial adviser. StratMap models the structure you enter; it does not recommend one.

Sequencing the pivot

Step 1: confirm the borrowing position with a broker

A broker can run a borrowing capacity assessment for another investment property. Lenders differ, and the broker confirms the figure.

Step 2: identify the specific commercial thesis

Not "commercial" as a category. A specific property, area, sector, and tenant profile. Retail strip in a Queensland regional centre. Suburban Melbourne office. Industrial in Perth's south. Each has different DD requirements, cap rate ranges, and vacancy risks.

Step 3: line up the specialist team

• Commercial buyers agent (different licence from residential in most states)
• Commercial solicitor (leases are not residential contracts)
• Accountant reviewing structure (personal name vs company vs SMSF)
• Broker with commercial lending experience

Step 4: model in the tracker

Add the candidate property to your tracker with commercial defaults. See how it interacts with your existing residential portfolio's cash flow. Does the positive cash flow offset any pending negative gearing on your residentials? What does the combined 10-year projection look like? Does the modelled Stage 4 date move forward or back?

Step 5: DD, negotiate, settle

The execution phase is similar to residential but with WALE analysis, tenant covenant checks, and lease review clause negotiation front and centre. 60-90 day settlements are typical, sometimes longer.

Step 6: resume the residential arc when capacity rebuilds

The pivot doesn't end residential. It creates a bridge asset that generates cash flow while your personal capacity rebuilds. In this modelled example the borrowing test shows headroom for another residential purchase by years 4 to 6; a broker confirms lending.

Common commercial pivot mistakes

1. Buying a commercial property because your residential broker said no. Model a commercial scenario against the same goal and compare it with the alternatives.
2. Chasing yield without covenant. A 9% cap rate on a suburban office with a shaky tenant is worse than a 6.5% cap rate with a solid tenant. Cap rate reflects risk. Read the tenant covenant carefully.
3. Skipping the WALE analysis. A 12-month lease left on the tenant means you might be re-leasing at year 2. Bank knows this. Values property lower. Vacancy risk elevated.
4. Buying commercial in a state where you have no network. Local knowledge matters more for commercial than residential. If you don't have a property manager, business broker, or commercial agent relationships in the state, you're at a disadvantage on re-leasing when the time comes.
