Borrowing capacity under the DTI limit
Lenders now cap high debt-to-income lending at 20 per cent of new investor loans each quarter. If your total debt including the new loan sits at six times your gross income or more, you fall into that limited allocation. Consider a lawyer on $180,000 gross who owns a $650,000 owner-occupied mortgage with $550,000 outstanding and applies for a $500,000 investment loan. Total debt would be $1,050,000, giving a DTI of 5.8. That application clears the threshold. The same lawyer applying for a $600,000 investment loan pushes the DTI to 6.4, placing the application into the restricted band. Most lenders process these within their quarterly allocation on a first-come basis, so timing matters when your DTI sits near the cut-off.
The DTI calculation includes all debt serviced by the applicant, including credit cards at their limit, personal loans, and any guarantor exposure. Lenders still assess serviceability at the product rate plus a 3.0 percentage point buffer, but the DTI limit operates as a separate gate. If you hold unused credit card limits totalling $40,000, lenders assume a monthly repayment obligation even if the balance is zero. Closing or reducing limits before application can shift your DTI below six and move you out of the restricted allocation.
Structuring the loan around negative gearing rules
Investment properties acquired after 12 May 2026 that are not eligible new builds attract quarantined losses from the 2027-28 income year onward. Losses on those properties can only offset income from other residential investments, not salary. That changes the cash flow profile for any established dwelling purchased now. In our experience, lawyers who previously relied on full negative gearing to absorb holding costs now model the property to break even or produce positive cash flow within 18 months. The usual holding costs on an established two-bedroom unit include interest, council rates, strata levies, insurance, property management fees and allowances for vacancy and maintenance.
A property returning $550 per week in rent with a $500,000 loan at current variable rates might carry annual interest around $25,000, with other outgoings adding another $8,000. That leaves an annual shortfall before tax relief. Under the new rules, that shortfall cannot reduce your taxable salary unless you also hold other residential investment income or capital gains to absorb it. Some lawyers are pairing an established property with a new build in the same financial year so that the new build's deductible losses offset both properties' income and preserve some salary offset. Others are increasing their deposit to reduce the loan amount and push the property closer to neutral cash flow from the outset. Both approaches require upfront capital, either as deposit or as funds to acquire a second property, so the choice depends on your liquidity and appetite for portfolio growth at this stage.

Interest-only periods and portfolio expansion
Interest-only repayments reduce the monthly cost and preserve cash flow during the early years when rental income may not cover all outgoings. Most lenders offer interest-only terms of up to five years on investment loans. After that period, the loan reverts to principal and interest unless you apply to extend. The benefit for lawyers building a portfolio is that lower monthly repayments increase serviceability on the next application. If you plan to acquire a second investment property within three years, keeping the first loan interest-only until that purchase is settled gives you more borrowing capacity when the second application is assessed.
Under APS 112, a loan with an interest-only period longer than five years and an LVR above 80 per cent is classified as non-standard and attracts a higher risk weight, which flows through to a higher rate. That classification rarely applies in practice because most lenders cap the initial interest-only term at five years and require LMI on loans above 80 per cent LVR. If you are considering an interest-only loan structure, confirm the term and rate treatment with your lender before submitting the application.
Using equity from your owner-occupied property
Most lawyers fund the deposit and costs on their first investment property by releasing equity from their home. Lenders treat the two loans separately. The owner-occupied loan remains at the owner-occupied rate, and the new investment loan is priced at investor rates. The investment loan itself does not need to be secured solely over the investment property. Some lenders allow cross-collateralisation, where both properties secure both loans, but this structure limits your ability to sell or refinance one property without affecting the other. The cleaner approach is to keep the securities separate: the owner-occupied loan secured over your home, and the investment loan secured over the rental property.
If your home is worth $900,000 with a $400,000 mortgage, your equity is $500,000. Lenders typically allow you to borrow up to 80 per cent of the property's value without LMI, giving you access to $720,000 in total debt against that security, which means $320,000 of usable equity. That amount covers the deposit and costs on a property up to about $1,400,000 if you provide a 20 per cent deposit, though your serviceability will cap the loan amount well before that figure in most cases. For a more detailed breakdown of how to structure equity release alongside an investment loan application, the calculation depends on your current loan balance, the valuation, and the lender's maximum LVR policy.
Rate discounts and fixed versus variable
Investor variable rates sit roughly 20 to 60 basis points above equivalent owner-occupier rates at most lenders. The discount you receive off the lender's published rate depends on the loan amount, LVR, and whether you hold other products with that lender. Lawyers with an existing owner-occupied loan often receive a larger discount when they place the investment loan with the same lender, but that benefit needs to be weighed against the rate and features available from other lenders. A 0.15 per cent discount applied to a less competitive starting rate may still leave you paying more than a lender offering a smaller discount from a lower base rate.
Fixed rates provide certainty during the fixed term but typically do not allow extra repayments above a small annual threshold, often $10,000 to $20,000, without incurring break costs. If you plan to make lump-sum repayments from bonuses or to pay down the loan early, a variable loan or a partial fix is more suitable. Splitting the loan 50-50 between fixed and variable gives you certainty on half the debt while retaining full offset and repayment flexibility on the variable portion. We regularly see lawyers use the variable split as the offset account holder, parking rental income and other funds to reduce the interest charged on that portion without losing access to the cash. For guidance on structuring your rate and refinancing options, the product choice depends on your cash flow, repayment intentions, and rate outlook.
What to prepare for the application
Lenders require evidence of rental income, either from a signed lease or a rental appraisal. Most lenders accept 80 per cent of the appraised weekly rent as assessable income to offset the loan's holding costs in their serviceability calculation. If the property is already tenanted, provide the signed lease. If it is being sold with vacant possession, obtain a written rental appraisal from a licensed property manager in the area. The appraisal should state the expected weekly rent, the comparable properties used to form that view, and the likely vacancy rate for that property type.
You will also need to provide your most recent payslips, tax returns if you have other income sources, and evidence of your deposit, including bank statements showing the funds held for at least three months. If you are using equity from your home, the lender will arrange a valuation of that property as part of the application. Lenders assess rental income net of a vacancy allowance and management fees. The allowance varies by lender but typically sits between 5 and 10 per cent for vacancy and around 7 to 8 per cent for management. These assumptions reduce the income figure the lender uses in their serviceability calculation, so the actual rental return needs to exceed the loan's holding costs by a margin to satisfy the assessment.
LMI waivers and reduced LMI for lawyers
Several lenders offer LMI waivers or reduced LMI for lawyers on residential loans, but most of those concessions apply only to owner-occupied lending. LMI on investment loans is typically calculated at the standard rate regardless of profession. However, a small number of lenders extend their lawyer LMI discount to investment properties, allowing you to borrow up to 90 per cent LVR with a reduced or waived premium. That difference can be $15,000 to $25,000 on a loan amount around $500,000. The waiver usually requires you to meet minimum income and employment criteria, such as two years of continuous employment and a gross income above a set threshold, often $100,000 or higher. If you qualify for an LMI concession, the reduced upfront cost frees up capital for a larger deposit on your next purchase or to cover holding costs during the first year.
When to consider refinancing after purchase
Most lawyers refinance their investment loan within two to four years of purchase, either to access a lower rate or to release equity for the next acquisition. If your property has increased in value and your loan balance has reduced, either through principal repayments or market movement, you can refinance to access that equity without selling. The new lender will revalue the property as part of the refinance assessment. If the property was purchased for $600,000 and is now valued at $680,000, and your loan balance is $480,000, your LVR has dropped to around 70 per cent. That improved position allows you to borrow additional funds against the property or to negotiate a lower rate based on the reduced risk.
Refinancing also resets the interest-only period if you choose to revert to interest-only on the new loan. That option is useful when you are preparing to acquire another property and need to maximise serviceability again. If you are within a fixed-rate term, check the break costs before proceeding. Break costs apply when you exit a fixed loan early and rates have fallen since you fixed. The cost can be substantial, often several thousand dollars, and may outweigh the benefit of refinancing unless the rate improvement or equity release justifies the expense.

Frequently Asked Questions
Does the 20 per cent DTI limit apply to all investment loan applications?
The limit applies only to applications where your total debt is six times your gross income or higher. If your DTI is below six, the limit does not affect your application.
Can I still negatively gear an investment property purchased now?
Yes, but losses on established properties acquired after 12 May 2026 can only offset other residential property income from the 2027-28 income year onward, not salary. New builds remain fully deductible against all income.
What is the usual interest-only period on an investment loan?
Most lenders offer interest-only terms up to five years. After that, the loan reverts to principal and interest unless you apply to extend the interest-only period.
Do LMI waivers for lawyers apply to investment loans?
Most LMI waivers for lawyers apply only to owner-occupied lending. A small number of lenders extend reduced LMI to investment loans for lawyers who meet income and employment criteria.
How do lenders assess rental income for serviceability?
Lenders typically accept 80 per cent of the appraised or actual rental income, net of a vacancy allowance of 5 to 10 per cent and management fees around 7 to 8 per cent.
