Do you know what lenders check for investment loans?

Lenders assess investment loan applications differently to owner-occupier loans, and the difference can catch even experienced borrowers off guard.

The approval process weighs rental income, existing debt, and serviceability at higher test rates because the lender is backing you to manage two properties, not one. If you're looking at an investment property in Wallsend or the broader Lake Macquarie area, understanding what gets scrutinised will save you time and position you to move quickly when the right opportunity appears.

Rental Income Gets Discounted Before It's Counted

Lenders do not add the full rental income to your serviceability calculation. Most lenders apply a 20 per cent discount to the expected rent to account for vacancy periods, maintenance costs, and the possibility the property sits empty between tenants. That means if a property in Wallsend is expected to rent for $500 per week, the lender will only credit you with $400 per week when assessing how much you can borrow.

Consider a buyer who already owns their home in Hexham and wants to purchase a two-bedroom unit near Wallsend Plaza. The unit is advertised with an expected rental return of $480 per week. After the 20 per cent shading, the lender treats that as $384 per week of income. If the buyer is also carrying a $2,200 monthly car loan and has a $450,000 mortgage on their home, the net effect is that the rental income adds less to their borrowing capacity than they expected, and the car loan works against them more heavily under borrowing capacity rules.

Some lenders apply a higher discount rate, closer to 25 per cent, and a handful will vary the rate depending on the type of property or location. Apartments in buildings with high owner-occupier ratios sometimes receive a lower discount than those in predominantly investor-held complexes.

Serviceability Is Tested at a Rate 3 Percentage Points Higher

Every lender is required to assess whether you can still afford the loan if the interest rate rises. The test rate sits at least 3 percentage points above the actual loan rate. If you're offered a variable rate investment loan at 6.5 per cent, the lender will assess your ability to repay at 9.5 per cent or higher.

This buffer was increased from 2.5 to 3 percentage points in late 2021 and has been maintained through every regulatory update since. It applies to all new residential loans, but it has a sharper impact on investment loans because rental income is already being shaded and because many investors are also servicing their own home loan at the same time.

In our experience, applicants who assume their current income and expenses will comfortably support a second loan often find the serviceability test tighter than expected once the buffer and rental shading are applied together.

Debt-to-Income Limits Apply Separately to Investors

From February, lenders have been restricted in how much they can lend to borrowers with high debt-to-income ratios. No more than 20 per cent of new investor loans at any lender can be written at a DTI of 6 times gross income or greater, and the cap applies separately to investor lending and owner-occupier lending.

If your total debt across all mortgages, car loans, and other commitments sits at or above six times your annual household income, you may still be approved, but the lender has less room to accommodate your application within their regulatory allocation. The limit does not apply to new construction or newly erected dwellings, so buyers looking at newly completed townhouses or units in Wallsend may find slightly more flexibility in serviceability than those purchasing established stock.

Deposit and Equity Requirements Are Higher for Investment Lending

Most lenders will lend up to 90 per cent of the property value for an investment loan, but the borrower will need to pay lenders mortgage insurance on any amount above 80 per cent. LMI premiums for investor loans are higher than for owner-occupiers at the same loan-to-value ratio, and some lenders cap investor lending at 80 or 85 per cent regardless of LMI.

If you're using equity in your existing home to fund the deposit, the lender will require a valuation of both properties and will calculate the total loan-to-value ratio across your portfolio. Where two loans are secured against the same property, the amounts are combined for the purpose of determining LVR and capital treatment under the lender's risk model.

Wallsend sits within a region where valuations have remained relatively stable, but lenders will still apply their own adjustments based on property type, location risk, and the current condition of the dwelling. Units in older blocks or properties on busy roads near the rail line may be valued more conservatively than detached homes in quieter pockets near Fletcher Park.

Interest-Only Periods Are Shorter and Require Stronger Justification

Many investors prefer interest-only repayments to maximise cash flow and tax deductions in the early years of ownership. Lenders will offer interest-only periods on investment loans, but the maximum term is usually five years, and the loan will revert to principal and interest repayments after that time unless you apply to extend.

Applications for interest-only terms are assessed more closely than principal and interest loans. The lender will want to see that you can service the loan on a principal and interest basis at the test rate, even if you're only making interest payments initially. If the loan-to-value ratio is above 80 per cent and the interest-only period requested is longer than five years, the loan is classified as non-standard and will attract additional scrutiny and higher capital requirements for the lender, which usually translates to a higher rate or a declined application.

Some lenders have tightened their interest-only policies further in response to regulatory settings and are now requiring a lower maximum LVR or a larger deposit before they will approve interest-only terms on investment lending.

Existing Investment Properties Add Complexity to Serviceability

If you already own one or more investment properties, each of those loans and their associated rental income will be factored into your new application. The lender will request rental statements or lease agreements for each property and will apply the same shading to the income.

In a scenario where an investor in Wallsend already owns a unit in Mayfield and is looking to purchase a second investment property, the lender will assess both the Mayfield rental income (shaded by 20 per cent) and the proposed Wallsend rental income (also shaded) against the total debt serviceability requirement across both loans plus the investor's own home loan if applicable. This layering effect means that refinancing one or more existing loans to a lower rate or consolidating debt before applying for a new investment loan can materially improve your borrowing capacity.

Negative Gearing Rules Change from July 2027

For properties purchased from mid-May this year onward, new tax rules take effect from 1 July next year. Rental losses on residential investment properties acquired after that date can no longer be offset against salary or wage income. Losses can only be carried forward and offset against future rental income or capital gains from residential property sales.

Properties purchased before that date, and properties classed as eligible new builds, remain exempt from the change. Eligible new builds include dwellings constructed on previously vacant land and developments that increase the total number of dwellings on a site. A knock-down rebuild that replaces one house with one house does not qualify, but a subdivision that replaces one house with two townhouses does.

This shift does not directly change how lenders assess your application now, but it does change the after-tax cash flow position for investors who were relying on negative gearing to reduce their taxable income. Lenders are aware of the change and some have adjusted their appetite for lending to investors who will be affected, particularly where the investor's serviceability is marginal and depends on the tax benefit to maintain cash flow.

Documentation Requirements Are More Detailed

Lenders require more supporting documentation for investment loan applications than for owner-occupier loans. In addition to the usual income verification, you will need to provide evidence of rental income for any properties you already own, a copy of the lease or a rental appraisal for the property you intend to purchase, and proof of savings or equity to cover the deposit and settlement costs.

If you're self-employed, the lender will generally require two years of tax returns and often two years of business financials as well. If you're using a rental appraisal rather than an existing lease, the lender may discount the appraised rent further or require a second opinion depending on the property type and location.

Body corporate records are requested for units and townhouses, and lenders will review the sinking fund balance and any upcoming special levies. A building with a low sinking fund or a history of large levies may be declined or valued more conservatively, which affects the loan amount you can access.
