Income and Employment: Everything First Home Buyers Need

Your income matters less than you think, and your employment history matters more.

When you apply for a home loan, lenders aren't just checking whether you earn enough money right now. They're trying to predict whether you'll still be earning that money in three years, or five, or ten. For first home buyers, understanding this distinction changes how you prepare your application and when you choose to submit it.

How Lenders Calculate Your Usable Income

Lenders take your gross income and apply a series of reductions before they decide how much you can borrow. Your base salary gets accepted at full value, but overtime and bonuses typically count at only 80% of their actual amount, sometimes less. Commission income often requires a two-year average, which means a stellar year last year won't help much if the year before was quieter.

Consider a buyer who earned $75,000 base salary plus $15,000 in overtime last year. The lender might use $75,000 plus $12,000 (80% of overtime), giving a usable income of $87,000 rather than the $90,000 actually earned. That $3,000 difference reduces your borrowing capacity by roughly $15,000 to $18,000 depending on the lender's calculation method. The buyer who understands this ahead of time knows whether their target property sits within reach or whether they need to adjust their search price.

Casual and Contract Workers Face Different Rules

Casual employment doesn't disqualify you from a home loan, but it does change which lenders will consider your application and how they assess your income. Most lenders require at least six months with your current employer and evidence of consistent hours. Some want twelve months. A handful will accept as little as three months if you're in an industry with stable casual employment patterns, like nursing or teaching.

Contract workers sit in a similar position. If you're on your third consecutive contract with the same employer or in the same field, many lenders will treat that income as stable. If you've just finished your first contract and started a second with a different employer, your options narrow considerably. In our experience, the gap between contracts matters more than the length of each one. A two-week break between a finished contract and a new one raises fewer concerns than a three-month gap, even if both contracts were twelve months long.

Self-Employed Buyers Need Two Years of Tax Returns

Self-employed income requires two full years of tax returns in almost every scenario. Lenders average your net profit across both years after adding back certain deductions like depreciation. If your business showed $68,000 profit in the first year and $82,000 in the second, the lender uses $75,000 as your income figure, not the more recent $82,000.

Some lenders offer low-doc or alternative documentation loans for self-employed borrowers who can't provide two years of returns, but these products typically come with interest rate premiums of 0.5% to 1.5% above standard variable rates and often require a deposit of at least 20%. For a loan amount of $500,000, that rate difference costs you an additional $2,500 to $7,500 per year in interest. Waiting until you have two complete tax returns before applying usually delivers better loan terms than rushing in early with alternative documentation.

Probation Periods and Recent Job Changes

Most lenders hesitate to approve a home loan application while you're still in a probationary period at a new job. The standard approach requires you to have completed probation or to provide a letter from your employer confirming your role will become permanent. A small number of lenders will approve applications during probation if you're moving within the same industry and your new income matches or exceeds your previous role.

Changing jobs just before or during your application creates timing pressure. If you've already received home loan pre-approval and then change employers, most lenders require you to re-submit for approval with updated employment details. That process can take another week or two, which matters when you're trying to meet a settlement deadline. Letting your broker know about any planned job changes before they happen gives you time to structure the application in the right order.

Rental Income From Investment Properties

If you're planning to rent out a room in your new home to help cover the mortgage, some lenders will include that rental income in their assessment. They typically use 80% of the expected rent to account for vacancy periods and maintenance costs. A room renting for $250 per week adds roughly $10,000 per year to your usable income after the lender applies their reduction, which can increase your borrowing capacity by $50,000 or more depending on your other commitments.

You'll need a rental appraisal from a local agent showing what that room or area of the property could achieve in the current market. The appraisal needs to be specific about whether the rent assumes a furnished or unfurnished room and whether utilities are included. Vague estimates won't satisfy most lenders.

How Multiple Income Sources Get Combined

When you're applying with a partner or co-borrower, lenders assess both incomes together but still apply their reduction rules to each person's variable income separately. If one of you earns a stable salary and the other has contract income with bonuses, the stable income holds more weight in the assessment. Some lenders will be more flexible with the second applicant's income type if the primary applicant has strong employment stability.

The key is understanding which income sources get you over the line and which ones just add a buffer. If your base salaries already support the loan amount you need, the casual loading or overtime becomes less critical to the approval. If you're relying on that extra income to reach your target, you need to know which lenders count it and at what percentage before you start shopping for properties.

Your employment and income situation shapes which lenders suit your circumstances and how much you can borrow. Getting that assessment right before you start looking at properties saves you from finding the right home only to discover it sits just outside your lending capacity.
