What Do Lenders Actually Look At When a FIFO Worker Applies for an Investment Loan?

Why does a high FIFO income not automatically mean high borrowing capacity?

Because serviceability is calculated using assessable income, and assessable income is usually lower than gross income.

Lenders apply adjustments before your pay reaches the serviceability calculator. Variable components may be discounted. Living expenses are benchmarked. Existing credit limits can be counted whether you use them or not. Applications are also stress-tested at a rate above the product rate: APRA currently requires authorised deposit-taking institutions to maintain a mortgage serviceability buffer of three percentage points.

A FIFO household earning well above the national average can therefore have an assessed capacity well below what the raw income suggests. That is not a judgement about the applicant; it is the result of the lender’s serviceability calculation.

How long do lenders want you to have been working FIFO?

It varies by lender, employment type and how much of the income is variable.

Published broker and lender guidance commonly points to 6–12 months in the current role as a baseline, with 12–24 months of history often preferred when allowances or overtime make up a meaningful share of pay. A longer record helps establish that variable income is a continuing pattern rather than a short run.

Time in the industry, not just time in the current job, can also matter. Some lenders may weigh a strong resources-sector history against shorter tenure in a current role, while others will not. This is one of the areas in which lender policy genuinely differs.

Does it matter whether you are permanent, casual, labour hire or on an ABN?

Yes. The same gross income can be treated differently depending on how the worker is engaged.

Two people on the same site, doing the same roster for the same money, may be assessed differently because of their employment arrangement. It is therefore risky to assume that another worker’s lending outcome predicts your own.

• Permanent full-time employment is generally the most straightforward and closest to a standard PAYG assessment.
• Fixed-term contracts may prompt questions about renewal history and the likelihood of the contract continuing.
• Casual and labour-hire income can attract longer history requirements and may be discounted because hours are not guaranteed.
• ABN contractors are generally assessed more like self-employed borrowers, using financials and contracts rather than payslips alone.

How are site allowances, LAFHA and overtime treated?

There is no single industry-wide approach; treatment depends on the payment, evidence and lender policy.

Published guidance describes a wide range of practice. Some lenders may count 100% of overtime, site allowances or bonuses when consistency is demonstrated over a sustained period. Others apply a shading factor, with published discounts commonly ranging from 20% to 50%. Some conservative policies exclude certain allowances entirely.

Living Away From Home Allowance (LAFHA) has an additional complication. The ATO treats a qualifying LAFHA payment as a fringe benefit rather than ordinary salary or wages. Some lenders include it in serviceability and others do not.

If allowances form a large share of pay, the same application can therefore produce materially different outcomes across lenders. This is not a reason to submit multiple applications blindly, because applications can affect your credit file. It is a reason to have a qualified mortgage broker match the income structure to lender policy before an application is submitted.

Whether a particular site allowance will count depends on the allowance, employment contract, income history and lender. A guide cannot answer that for an individual file.

What evidence helps turn variable pay into countable income?

Lenders generally look for consistent documents that show the payment is regular and connected to the role.

An employment letter can be particularly useful. An allowance that is documented as a standing condition of the role may be easier for a lender to assess than one that appears discretionary.

• Recent payslips with year-to-date figures that support the income pattern.
• A PAYG income statement, payment summary or tax return covering a full financial year.
• The employment contract.
• An employment letter confirming the roster and that allowances are a standing condition of the role.

How is rental income assessed on an investment loan?

Lenders usually include only part of gross rent in serviceability calculations.

This is known as rental income shading. The commonly published range for major lenders is around 70–80% of gross rent, allowing for vacancy, management fees, maintenance and rent shortfalls. A difference between 70% and 80% can be material on the same application.

If the property is not yet tenanted, lenders will generally request a rental appraisal from a licensed property manager and may be more conservative with projected rent. A rental estimate in a marketing brochure should be expected to undergo independent lender assessment, just as it should in the buyer’s own investment analysis.

What else moves the number that has nothing to do with income?

Living expenses, existing credit and the proposed property can each reduce assessed capacity.

Living expenses: lenders compare declared expenses with internal or industry benchmarks and generally use the higher figure. Higher income does not remove this assessment.

Existing credit: credit cards are commonly assessed using the limit rather than the current balance. Personal and car loans, HECS-HELP, buy-now-pay-later accounts and other commitments can also affect capacity. Missed payments and defaults may be visible on a credit report.

The property itself: lenders assess the security as well as the borrower. Mining-dependent and remote locations may attract lower maximum loan-to-value ratios, requiring a larger deposit. For a resources-sector worker, buying in a town dependent on the same industry can also concentrate employment and asset-value risk.

What does this mean for a FIFO worker thinking about investing?

Understand your finance position before choosing a property, not after.

Income is the input most people focus on. Structure, history, documentation and existing commitments determine how much of it a lender may use. A worker with a clean credit record, more than 12 months of consistent payslips, clear statements, no unnecessary credit limits and an employment letter explaining the roster may present more clearly than someone earning more without that evidence.

The practical sequence is to understand your position, assess what is realistic and then begin looking at property. Choosing a property before finance has been properly assessed can create settlement risk.

Where should a FIFO worker go next?

For an individual borrowing-capacity assessment, speak with a qualified mortgage broker who understands FIFO income structures.

Kallea works alongside broker partners and can make an introduction, but does not provide credit assistance. Questions about an individual income structure, lender choice or application belong with the broker.

Kallea’s investment readiness assessment can also help you review employment structure, documentation, commitments and deposit position before speaking with a broker. It is a general starting point, not a credit assessment or indication of approval.
