Beginner's Guide to Investment Loan Pre-approvals

Pre-approval for an investment loan tells you how much a lender will commit to before you sign a contract.

Most buyers in Eltham searching for a rental property assume they can borrow the same amount for an investment as they could for a home to live in. That assumption costs deposits every settlement period when conditional finance falls through because serviceability was tighter than expected or the lender needed rental income verified before unconditional approval.

Why Investment Loan Serviceability Differs from Owner-Occupied Loans

Lenders assess investment loans using rental income at 80 per cent of market rent, then apply a serviceability buffer three percentage points above the actual rate. That buffer has been in place since mid-2025 and applies to every application. If a property in Eltham generates $2,400 per month in rent, the lender calculates your income at $1,920 per month before adding the interest cost and principal repayment to your existing commitments. An owner-occupied loan does not include rental income but also does not factor in vacancy, management fees, or the reduced income assumption. The result is that your maximum investment loan amount will almost always sit below your owner-occupied borrowing capacity, sometimes by 15 to 20 per cent depending on your other debts and income structure.

Consider a buyer who earns $110,000 per year with no dependents and a $35,000 car loan. For an owner-occupied purchase their borrowing capacity might reach $620,000. For an investment property, the same buyer with the same deposit might be offered $520,000 because the lender applies the vacancy and expense assumptions even when the property has a sitting tenant. That gap narrows if you already own property and can use verified rental income from an existing lease, but it rarely disappears.

How Debt-to-Income Limits Affect Eltham Investors

From February this year, lenders can only write 20 per cent of new investment loans at a debt-to-income ratio of six times or more. If your total borrowing including the new investment loan exceeds six times your gross annual income, you fall into that constrained portion of the lender's book. Some lenders stop lending above that threshold entirely rather than manage the allocation. Others approve the loan but require a larger deposit or apply a higher interest rate to bring your application within their risk settings. This cap applies separately to investment lending and owner-occupied lending, so your DTI on an investment loan is calculated without reference to loans on your own home.

In our experience, buyers who wait until they find a property before seeking pre-approval often discover they need an extra $40,000 to $60,000 in deposit or equity to keep their DTI below six. That discovery two weeks into a 30-day finance clause creates pressure that rarely ends well.

What Lenders Assess During Investment Pre-approval

Pre-approval for investment finance requires your income evidence, liability statements, and an estimate of the property type and rental yield you intend to purchase. The lender will not value a specific property at pre-approval stage, but they will ask whether you are buying a unit or a house, and whether the postcode sits within their acceptable lending area. Eltham postcodes 3095 and nearby areas are well within metro Melbourne lending policy for all major banks, but some lenders apply loan-to-value ratio restrictions on units in certain postcodes or buildings with fewer than six dwellings. Knowing your target property type before you apply avoids a scenario where your pre-approval assumes a house but you purchase a unit in a small block that the lender then declines at formal application.

You will also need to nominate your intended loan structure at pre-approval stage. Most investors in Eltham choose interest-only terms for the first five years to manage cash flow and maximise tax deductions, then convert to principal and interest if the property has increased in value or their income has grown. Some lenders automatically assume principal and interest unless you request otherwise, which changes your repayment by 30 to 40 per cent per month and reduces your borrowing capacity accordingly. If you want interest-only and your pre-approval is calculated on principal and interest, your conditional approval amount will not match what the lender can actually settle.

Does Pre-approval Guarantee Unconditional Approval?

Pre-approval is conditional on property valuation, unchanged financial circumstances, and final credit assessment. If the property you contract to purchase values below the contract price, the lender will reduce the loan amount or decline the application unless you increase your deposit to cover the shortfall. If you change jobs, take on new debt, or reduce your income between pre-approval and formal application, the lender reassesses your serviceability and may withdraw the offer. Pre-approval is not a guarantee, but it does confirm that the lender has assessed your financial position and is prepared to lend subject to the property meeting their security requirements.

The valuation step catches most buyers who rely on pre-approval alone. A property listed in Research-Warrandyte Road or Main Road might attract strong interest from local buyers familiar with the area, but if comparable sales in the preceding 90 days sit below the contract price, the valuer will adopt the lower figure. That does not mean you overpaid. It means the lender will only advance funds against the value they can defend if they need to sell the property in a falling market. You either increase your deposit or renegotiate the contract.

How the Negative Gearing Changes from July 2027 Affect Pre-approval Strategy

Properties purchased after 12 May last year, other than eligible new builds, will have rental losses quarantined from 1 July next year. If your rental property runs at a loss, you will not be able to offset that loss against your salary until you sell or the property generates a profit. Lenders are still working through how this affects serviceability, but the early position from most credit teams is that they will continue to assess investment loans on net rental income after expenses regardless of whether you can claim the loss personally. That approach does not change how much you can borrow, but it does change the after-tax cash flow once the loan settles.

If you are considering a new build to retain full negative gearing benefits, your pre-approval needs to specify that the loan is for an eligible new residential dwelling. The lender will require evidence at settlement that the property qualifies, usually a statement from your solicitor and council records confirming the dwelling was constructed on previously vacant land or increased the number of dwellings on the site. A knock-down rebuild that replaces one house with one house does not qualify even if the new dwelling has never been occupied. Refinancing an established property into a new loan after July next year does not change its treatment because eligibility is determined by when the property was acquired, not when the loan was written.

Structuring Deposit and Equity Release Before You Search

Most buyers in Eltham use equity from their home rather than cash savings to fund an investment deposit. Equity release requires a valuation of your existing property and confirmation that your total borrowing including the new investment loan does not exceed 80 per cent of the combined security value if you want to avoid Lenders Mortgage Insurance. If you own a home valued at $900,000 with a $400,000 mortgage, you have $320,000 in accessible equity at 80 per cent LVR. That amount can cover a 20 per cent deposit on a property up to around $1.3 million in total, but only if your income supports the combined debt.

Getting equity release approved as part of your investment pre-approval means you know exactly how much deposit you can access and whether the lender will require LMI. Waiting until you have a contract signed before applying for equity release adds a second valuation, a second credit assessment, and at least another week to your approval timeline. If your home has dropped in value since you last refinanced, or if your offset account balance has reduced your available equity, you find out at the point where you have the least flexibility to adjust.

Choosing Between Variable and Fixed Rates at Pre-approval

You do not need to lock in your interest rate type at pre-approval stage, but you do need to tell the lender which structure you want them to assess. A variable rate investment loan gives you the ability to make extra repayments, redraw funds, and refinance without break costs. A fixed rate gives you payment certainty but restricts additional repayments to $10,000 or $30,000 per year depending on the lender, and you will pay break costs if you sell or refinance before the fixed term ends. Your borrowing capacity is the same under either structure because lenders assess serviceability at the same buffer regardless of whether you choose variable or fixed, but your cash flow and flexibility differ significantly.

Most investors we work with in Eltham split their loan between fixed and variable, fixing 50 to 60 per cent for rate certainty and leaving the rest variable for flexibility. That structure requires two loan accounts and slightly higher documentation at settlement, but it avoids the scenario where you want to sell or access equity two years into a five-year fixed term and face $15,000 in break costs.

How Long Investment Pre-approval Lasts and When to Reapply

Pre-approval for an investment loan lasts 90 days from the date of issue, though some lenders extend this to 120 days if your circumstances have not changed. If you do not find a property within that window, you will need to reapply with updated income evidence and liability statements. Lenders do not automatically renew pre-approval because your financial position and their credit policy may have shifted since the original assessment. A reapplication takes less time than the first submission if your income and debts are stable, but it is not instant.

If interest rates or APRA settings change between your pre-approval and your formal application, the lender applies the current serviceability rules even though your pre-approval was issued under the earlier settings. That risk is small across a 90-day window, but it is not zero. The serviceability buffer moved from 2.5 percentage points to 3 percentage points in July last year, and buyers with pre-approval issued in May last year found their borrowing capacity reduced by around 8 per cent when they applied for formal approval in September.

Knowing how much you can borrow, what deposit you can access, and which lenders will support your target property type removes the variable that costs buyers their contract. Call one of our team or book an appointment at a time that works for you.
