Beginner's guide to investment loan approval

Investment loan approval has changed substantially since February

Investment loan approval now operates under debt-to-income caps that restrict how many high-leverage applications a lender can approve in each quarter. Lenders assess serviceability at a rate three percentage points above the product rate, apply separate caps to investor and owner-occupier portfolios, and account for tax changes scheduled for July next year that will alter how rental losses are treated. The result is that approval depends less on the asset itself and more on how your income, existing debt, and rental projections align with the lender's quarterly allocation of high-DTI investor loans.

For family lawyers considering a first or second investment property, the change requires more precision in structuring the application. A borrower earning $180,000 with $450,000 in owner-occupier debt and seeking $600,000 for an investment property sits at a debt-to-income ratio of 5.8. That application can be approved without consuming the lender's 20 per cent high-DTI allocation. The same borrower seeking $700,000 crosses into a DTI of 6.4, which means the application competes for a limited number of approvals the lender is permitted to issue that quarter. If the lender has already allocated its quota, the application will be declined or deferred regardless of income stability or deposit size.

Rental income is assessed on a discounted net basis

Lenders apply a discount to projected rental income to account for vacancy, maintenance, and management costs. Most lenders use 80 per cent of the gross rent, though some apply rates as low as 70 per cent depending on property type and location. For a property generating $650 per week, the lender will assess serviceability using $520 per week. Interest on the loan, strata levies, insurance, and ongoing costs are then deducted from that figure to determine the net contribution to serviceability. If the property is negatively geared, the shortfall is added to your existing debt servicing obligations and tested against your income at the buffered rate.

Consider a family lawyer purchasing a two-bedroom apartment with an assessed rental income of $650 per week. After the 80 per cent discount, the lender assesses $520 per week. Interest on a $600,000 loan at the test rate of roughly 6 per cent plus the serviceability buffer equals around $1,040 per week. Strata levies, insurance, and management fees add another $150 per week. The property contributes a net loss of $670 per week, or $34,840 annually. That loss is added to the borrower's existing mortgage and personal expenses when determining whether income can service the combined debt. The rental income does not offset the loan repayment dollar-for-dollar. It is discounted first, then netted against costs, and only the result is applied to serviceability.

Loan to value ratio determines whether LMI applies

Lenders calculate loan to value ratio by dividing the loan amount by the property valuation. For investment lending, most lenders cap LVR at 90 per cent, and borrowing above 80 per cent triggers Lenders Mortgage Insurance. LMI is a one-off premium that protects the lender if the property is sold for less than the outstanding loan balance. The premium is calculated on a sliding scale based on LVR and loan amount, and it can be capitalised into the loan or paid upfront.

LMI waivers for lawyers are available from some lenders for owner-occupier loans, but most do not extend the waiver to investment lending. A family lawyer borrowing $720,000 to purchase an $800,000 investment property at 90 per cent LVR will pay LMI of approximately $20,000 to $30,000 depending on the lender. The same borrower using equity from an existing property to reduce the LVR to 80 per cent avoids the premium entirely. Where equity is available, releasing it to increase the deposit is often more efficient than paying LMI, particularly if the equity can be accessed without refinancing the underlying loan.

Debt-to-income caps apply separately to investor and owner-occupier portfolios

The DTI cap introduced in February applies separately to new investor loans and new owner-occupier loans. A lender may approve up to 20 per cent of its new investor lending at a DTI of 6 times or greater, and up to 20 per cent of its new owner-occupier lending at the same threshold. The caps are measured quarterly for significant financial institutions and on a four-quarter rolling basis for smaller lenders. The separation means a lender that has exhausted its high-DTI allocation for investors in a given quarter may still approve high-DTI owner-occupier applications, and vice versa.

For a borrower seeking investment finance late in a calendar quarter, the lender's remaining allocation becomes relevant. If the lender has already used most of its 20 per cent quota, applications above the 6 times threshold will be declined even if the borrower's income and expenses support the loan under serviceability testing. The allocation resets each quarter, so an application declined in March may be approved in April if the borrower's circumstances have not changed. Timing is not always controllable, but understanding that the cap is a hard limit rather than a guideline helps set realistic expectations during the application process.

Negative gearing rules change from July next year

From 1 July 2027, net rental losses on residential investment properties acquired on or after 7:30pm AEST on 12 May this year can only be offset against other residential rental income or carried forward. Losses cannot be offset against salary, wages, or other non-residential income. Properties acquired before that date and time, including those under contract awaiting settlement, continue under existing negative gearing rules until sold. Eligible new residential dwellings remain fully negatively geared regardless of purchase date, provided the property was constructed on previously vacant land or replaced an existing property in a way that increased the total number of dwellings.

A family lawyer purchasing an established apartment in July next year will not be able to offset a $25,000 annual rental loss against a $180,000 salary for tax purposes. The loss is quarantined and can only be used to reduce tax on future rental income or capital gains from residential property. The same lawyer purchasing a newly constructed apartment on land that was vacant before construction retains full negative gearing. The distinction depends on the construction type and timing, not the age of the property at purchase. A unit in a new development that was occupied for 13 months before being sold to an investor loses access to negative gearing for that second purchaser.

Lenders are beginning to adjust serviceability assessments to reflect the reduced tax benefit. Some lenders are applying a lower tax offset to rental losses on affected properties, which reduces the borrower's assessed after-tax income and tightens serviceability. Other lenders have not yet changed their calculators. The inconsistency means that structuring the application with a lender that has updated its policy may result in a lower borrowing capacity than applying with a lender still using pre-reform settings. For borrowers close to the DTI threshold, selecting the right lender can determine whether the application is approved without consuming the high-DTI allocation.

Interest rate structure affects cash flow and deductibility

Investment loans are available on variable, fixed, or split rate structures. Variable rates allow unlimited additional repayments and access to offset accounts, which can reduce interest costs if surplus cash is held in the offset. Fixed rates lock the rate for a chosen term, usually one to five years, but restrict additional repayments and do not allow offset accounts during the fixed period. A split structure applies a fixed rate to part of the loan and a variable rate to the remainder.

Interest only loans for lawyers are commonly used for investment properties because they maximise the deductible interest component and minimise cash outflow during the interest-only period, which is typically five years. Principal and interest repayments reduce the loan balance and build equity, but they also reduce the amount of deductible interest over time. A borrower with a $600,000 investment loan on interest only at a variable rate will pay roughly $2,500 per month in interest. The same loan on principal and interest repayments costs roughly $3,700 per month, with $1,200 of that amount going toward principal. The interest-only structure does not reduce the loan balance, but it improves cash flow and preserves the maximum deductible interest over the life of the loan.

Borrowing capacity is calculated using net rental income and existing commitments

Lenders calculate investment borrowing capacity by adding your assessable income, applying the discounted net rental income from the proposed property, deducting existing loan repayments at the buffered rate, and subtracting declared living expenses or a household expenditure measure. The remaining surplus is divided by the monthly repayment per $100,000 borrowed at the test rate to determine the maximum loan amount. The calculation is sensitive to small changes in income, rent, or existing debt.

A family lawyer earning $180,000 with $2,800 per month in existing mortgage repayments, $1,200 in personal expenses, and $2,080 in assessed rental income from the proposed property has a monthly surplus of roughly $10,080 after tax and expenses. At a test rate of 6 per cent plus the serviceability buffer, each $100,000 borrowed requires roughly $865 per month in repayments. Dividing the surplus by the repayment per $100,000 gives a borrowing capacity of approximately $1,165,000. If the same borrower has an additional $400 per month in car loan repayments, the surplus falls to $9,680 and the borrowing capacity drops to $1,120,000. Paying out the car loan before applying increases capacity by $45,000. The calculation does not account for future income growth or rate cuts. It is a snapshot based on current commitments and declared expenses at the time of application.

Investment loan refinancing can improve rate and structure

Existing investment loans can be refinanced to access lower rates, release equity, or restructure debt. Investment loan refinancing for lawyers is assessed under the same serviceability and DTI rules as a new application, so borrowing capacity may differ from the original approval depending on income changes, rate movements, and updated prudential settings. Refinancing to release equity for a deposit on a second investment property is treated as a new investor loan and is subject to the 20 per cent high-DTI cap if the combined DTI exceeds 6 times.

Refinancing an existing $500,000 investment loan and releasing $150,000 in equity results in a new loan of $650,000. The lender assesses the $650,000 against the borrower's current income, existing debt, and the rental income from the property securing the loan. If the borrower's total debt including the new investment loan exceeds 6 times their income, the application falls within the high-DTI allocation. The equity release itself does not trigger the cap, but the total debt-to-income ratio determines whether the application can be approved without restriction. Refinancing solely to reduce the rate on an existing balance without releasing equity is assessed as a refinance rather than new lending, and DTI caps apply with less impact unless the borrower is also increasing the loan amount.

The application requires income verification and rental appraisal

Lenders require recent payslips, tax returns, or financial statements to verify income depending on employment type. For salaried family lawyers, two recent payslips and a letter of employment or contract are standard. For self-employed practitioners or equity partners, lenders typically require two years of tax returns, notices of assessment, and business financials. The rental income must be supported by a rental appraisal or current lease if the property is already tenanted. The appraisal should be dated within 90 days of application and prepared by a licensed property manager or real estate agent in the area where the property is located.

A contract of sale, Section 32 statement, and body corporate records for strata properties are required at the time of formal approval. Lenders will order their own valuation once the application is lodged. The valuation may differ from the purchase price, particularly in markets where sale prices have moved quickly. If the valuation comes in below the contract price, the lender will calculate the LVR based on the lower figure, which may reduce the approved loan amount or require a larger deposit. The application timeline from lodgement to formal approval is typically two to four weeks, depending on the lender's current volume and the complexity of the borrower's income.
