Everything You Need to Know About Investment Loans

Securing finance for a rental property when you operate through your own company or trust is not the same as applying for a standard owner-occupier loan.

You face different documentation requirements, different serviceability calculations, and often a longer turnaround between application and approval. Lenders treat self-employed borrowers as higher risk, even when your business has operated profitably for years. That means knowing which lenders will accept your structure, how to present your income, and which loan features will support your investment strategy becomes essential before you start searching for property.

Why Lenders Assess Self-Employed Investors Differently

Lenders calculate serviceability using verified income, not turnover. If you operate as a sole trader, they will typically require two years of tax returns and Notices of Assessment to establish your net profit. If you trade through a company, they will assess your share of distributable profit or salary plus dividends, depending on how income is drawn. Most lenders apply a reduction to the profit figure to account for tax, and some will only accept income that has been consistently earned across both years.

The servicing buffer compounds this conservatism. APRA requires lenders to test your ability to repay at three percentage points above the product rate, and some lenders apply additional margin for investor loans. If you are applying at a variable rate of 6.5 per cent, the lender models repayment at 9.5 per cent or higher. Borrowers with employment income face the same buffer, but they do not also contend with lender adjustments to declared profit or refusals to average fluctuating income.

Debt-to-income caps, effective from February, place a further constraint. Lenders may fund no more than 20 per cent of new investor loans at a DTI of six times or greater. If your taxable income sits at $120,000 after deductions, a loan exceeding $720,000 will fall into that restricted pool. That does not mean you cannot borrow more, but it does mean fewer lenders will approve you, and approval may depend on how much of that lender's DTI quota remains at the time you apply.

Interest Only Repayments and Cash Flow Management

An investment loan structured with interest-only repayments for the first five years reduces monthly outgoings and preserves cash flow for other business expenses or further property acquisitions. The loan does not reduce in balance during the interest-only period, but all interest paid remains deductible if the property is rented or genuinely available for rent.

Consider a contractor who purchases a two-bedroom unit in Parramatta at the current median, borrows 80 per cent of the value, and elects a five-year interest-only term on a variable rate. Monthly repayments sit several hundred dollars lower than they would under principal and interest from day one, and that difference can be directed into an offset account linked to the loan, reducing the interest charged without affecting deductibility.

At the end of the interest-only period, the loan reverts to principal and interest unless you refinance or negotiate an extension. Some lenders allow one further interest-only term, others do not. Planning for that reversion now means you are not caught by a sudden increase in repayments when the term expires.

Variable Versus Fixed Investment Loan Rates

Variable rates allow full offset and unlimited additional repayments without penalty. If rental income exceeds expectations or you receive a large contract payment, you can park surplus funds in the offset and reduce interest immediately. Variable rates also adjust with the market. If the Reserve Bank cuts the cash rate, your repayment typically falls within weeks.

Fixed rates lock in certainty for one to five years, but most fixed products do not offer offset and cap additional repayments at $10,000 to $30,000 per year. Exceeding that cap triggers break costs. For investors with variable income, losing access to offset can be costly. A contractor who invoices $40,000 one month and $8,000 the next benefits more from holding surplus cash in an offset against a variable loan than from fixing a rate that saves 20 basis points but removes flexibility.

Split loans, where part of the debt is fixed and part remains variable, offer middle ground. You retain offset access on the variable portion and lock in a portion of your repayment. Most lenders allow splits at any ratio you choose, though some require each split to exceed a minimum balance of $50,000 or $100,000.

Structuring Ownership and Loan Security

How you hold the property affects land tax, asset protection, and how lenders assess the loan. Holding the property in your personal name keeps the application simple and gives you access to the full range of lender products. Holding it through a trust or company can provide asset protection and flexibility in distributing rental income, but fewer lenders will accept those structures, and those that do often apply margin to the rate or require lower loan-to-value ratios.

If you already own your principal place of residence, lenders may ask whether you are willing to offer it as additional security. Cross-collateralising your home and investment property can increase borrowing capacity, but it also means the lender holds a mortgage over both assets. If the investment property falls in value or rental income drops, the lender's exposure is secured across your entire portfolio. Keeping each property on a separate loan, even if held with the same lender, preserves flexibility to sell or refinance one without affecting the other.

Tax Settings and How They Affect Your Return

All interest on a loan used to acquire or hold a rental property remains deductible, provided the property is rented or genuinely available for rent. Borrowing costs, including application fees, valuation fees, and lender legal costs, are also deductible, either in the year incurred or amortised over five years.

From 1 July 2027, net rental losses on residential properties acquired after 7:30pm AEST on 12 May 2026 will be quarantined and can only be offset against other residential rental income or carried forward. Losses cannot be offset against salary, contract income, or business profit. Properties purchased before that date, including those under contract awaiting settlement at that time, remain grandfathered under existing negative gearing rules until sold. Eligible new residential dwellings, defined as properties constructed on previously vacant land or developments that increase the number of dwellings, continue to allow negative gearing under the old rules regardless of purchase date.

If you are acquiring established property after mid-May, you need to model the investment assuming losses remain quarantined. That typically means targeting properties with stronger rental yields or holding sufficient other rental income to absorb the loss. Many self-employed investors already carry rental income from an earlier purchase, and quarantining applies across your entire residential portfolio, not per property. One positive-gearing property can absorb losses from another.

Capital gains tax discount arrangements also change from 1 July 2027. Gains accruing after that date on affected assets will no longer receive the 50 per cent discount. Instead, the cost base will be indexed for inflation and the real gain taxed at a minimum 30 per cent rate. Gains accrued before 1 July 2027 on properties already held continue under current rules. Eligible new builds allow you to elect between the 50 per cent discount and the indexed cost base with the minimum rate.

Equity Release and Portfolio Growth

Once your first investment property increases in value, you can access that equity to fund the deposit on a second property without selling the first. Lenders will typically lend up to 80 per cent of the property's current value without requiring Lenders Mortgage Insurance. If the property was purchased at $650,000 and is now valued at $750,000, 80 per cent of the new value is $600,000. If your existing loan sits at $520,000, you have access to $80,000 in usable equity, less refinancing costs.

That equity can fund the deposit and stamp duty on the next acquisition, but serviceability still applies. The lender will assess whether your income supports both the existing loan and the new borrowing, tested at the buffer rate. Self-employed borrowers often find serviceability, not deposit, is the constraint. Rental income from the existing property is included in serviceability calculations, but most lenders apply a shading of 20 per cent to account for vacancy, maintenance, and management costs. If the property generates $30,000 in annual rent, the lender will credit you with $24,000.

Application Process and Documentation for Contractors

You will need two years of individual tax returns and Notices of Assessment if you operate as a sole trader, or two years of company or trust financials plus your personal returns if you trade through a structure. Lenders will also request a letter from your accountant confirming your role, your share of profit or income, and that the business continues to trade. Some lenders require business activity statements for the most recent quarter to verify ongoing turnover.

If you have recently changed structure or commenced trading under a new ABN, most lenders will not accept that income unless you can demonstrate you were performing the same role under a previous structure and the client base has transferred. Moving from employment to contracting in the same industry is often acceptable if you can show continuity of work with the same end client.

Valuation is ordered by the lender once the application is submitted, and the valuer attends the property within a week in most metro areas. If the valuation comes in below the contract price, the lender will reduce the approved loan amount and you will need to cover the shortfall from savings or renegotiate the contract. Desktop and kerbside valuations are used for some refinance transactions, but not for new purchases.

Settlement typically occurs 30 to 90 days after exchange of contracts. Lenders require at least three weeks from formal approval to settlement to prepare documents, conduct final checks, and instruct their solicitor. Applying before you sign a contract allows time to address any documentation issues or explore alternative lenders if your preferred option declines.
