Turn a Long Off-the-Plan Wait Into Borrowing Power Momentum

Buying off‑the‑plan gives you something most buyers never get: time.

If you use the 6–18 months before settlement well, you can significantly increase your borrowing capacity, reduce stress, and lower the risk of a last‑minute finance scramble. If you drift, you’re at the mercy of higher rates, tighter bank policy and any valuation drop.

In this guide, we’ll unpack what actually moves your borrowing capacity in that wait period, then turn it into a practical, week‑by‑week style plan you can start now.

The build period is your best window to reshape borrowing capacity before settlement.

1. How lenders will really assess you at off‑the‑plan settlement

For off‑the‑plan purchases, the only assessment that truly matters is the one done just before settlement – not the pre‑approval you got when you signed the contract. Lenders reassess using your latest income, debts, credit file, the current interest‑rate environment and a fresh valuation, regardless of earlier approvals. That’s built into most credit policies and is especially important for self‑employed buyers.

1.1 The serviceability test in plain English

When a bank checks your borrowing capacity, they:

1. Add up your income (and usually shade some types like overtime, bonus, commissions and distributions).
2. Subtract a benchmark living expense (HEM) or your declared expenses, whichever is higher.
3. Add in all your existing and proposed debts with repayments tested at a higher rate.
4. Check that the surplus is big enough to safely cover the loan.

Under APRA guidance, Australian lenders generally test repayments at a rate at least 3 percentage points above the actual rate, even for interest‑only loans. If your real rate is 6%, they might assess you at ~9% on principal‑and‑interest, which can slash capacity compared with simple online calculators.

1.2 Why off‑the‑plan makes this trickier

With off‑the‑plan, two extra moving parts matter:

• Timing of income evidence – at settlement they’ll use your latest payslips, tax returns and financials, not the ones from 18 months ago.
• Final valuation – most lenders will lend against the lower of the contract price or the final valuation. If values soften, the effective LVR can rise and you may need more cash or cop LMI.

That’s why the build period is your chance to:

• Simplify and reduce consumer debt.
• Present stronger, more stable income.
• Build a dedicated settlement buffer.

2. Where extra borrowing capacity usually comes from

You don’t control interest rates or RBA decisions, but you do control how your situation looks when the bank re‑tests you. In practice, extra capacity usually comes from four levers.

2.1 Cleaning up expensive or messy debts

Unsecured debts hurt you twice:

• Their actual repayments reduce your surplus.
• Lenders may apply assessed repayments that are higher than what you pay.

Examples:

• Credit cards: assessed on a percentage of the limit (often 3% p.m.), not your actual spend.
• Buy now pay later: can be treated as ongoing commitments.
• Personal and car loans: converted into principal‑and‑interest at buffered rates.

Paying down or closing these can move your borrowing capacity more than a modest pay rise.

Worked example – closing a credit card
A $15,000 card limit might be assessed at 3% per month = $450 p.m. At a buffered 9% test rate, that $450 could support roughly $60,000–$75,000 of extra home loan borrowing capacity, depending on your income and lender policy.

2.2 Presenting stronger income

Lenders reward stability and clarity:

• PAYG: they like a consistent salary, with overtime/bonus averaged over 6–24 months.
• Self‑employed: they tend to use 2 years’ tax returns, often taking the lower year or an average.
• Small business owners: heavy deductions and profit minimisation reduce borrowing power.

Planning salary and profit distributions 12–24 months before a major property purchase can significantly improve borrowing power versus last‑minute restructuring. If you’re a business owner, align your tax planning with lending, not against it – see Income, Tax and Borrowing Power: A Business Owner’s Balancing Act.

2.3 Tightening living costs (but only realistically)

Lenders compare your declared living costs to the Household Expenditure Measure (HEM). With ABS data showing living costs up 3.7–4.7% annually in recent releases, banks are understandably sceptical of unrealistically low budgets.

Real wins tend to come from:

• Clearing recurring subscriptions and unused services.
• Negotiating big-ticket bills (insurance, utilities, telecoms).
• Reducing discretionary spend 3–6 months before application so your statements match your story.

2.4 Structuring your loans and buffers

The way you structure your existing debts before settlement can also shift capacity:

• Extending remaining terms on small personal loans can cut monthly repayments.
• Consolidating multiple small debts into a single, cheaper facility (used carefully) may improve servicing.
• Building a separate settlement buffer (beyond your emergency fund) reduces the risk of a valuation shortfall or extra LMI.

For investors, the structure between home and investment debt also matters, especially with changing negative gearing rules – see New Negative Gearing Rules: What They Do To Your Borrowing Power.
