Proven tips to secure investment loan pre-approval

Pre-approval for an investment loan gives you a written borrowing limit from a lender before you commit to a property. It tells you how much you can borrow and confirms that your financial position meets the lender's credit policy at the time of assessment.

Why pre-approval matters for South Australian investors

South Australian investors face two regulatory settings that make pre-approval more valuable than it was two years ago. Since February, each bank can fund no more than 20 per cent of new investor loans at a debt-to-income ratio of 6 times or greater. Once a lender hits that cap for the month, an application that would have been approved in January may be declined in March. Pre-approval places you in the queue before that limit is reached. The second setting is the 3 percentage point serviceability buffer, which forces lenders to assess whether you can afford repayments at a rate 3 per cent higher than the actual loan rate. That calculation reduces how much rental income the lender will count and increases the income you need to service the debt.

Consider a buyer who earns $95,000 and wants to purchase a unit in Norwood as a rental property. At a variable rate around 6.2 per cent, the lender tests serviceability at 9.2 per cent. If the unit rents for $450 per week, the lender may only count 80 per cent of that income after allowing for vacancy and maintenance. The borrower's maximum loan amount might be $420,000. Without pre-approval, the buyer could bid on a $550,000 property, win the auction, and discover two days later that no lender will fund the purchase. Pre-approval prevents that scenario.

What lenders assess during the pre-approval process

Lenders assess your income, existing debts, credit history, deposit size, and the type of property you intend to buy. For investment loans, they apply a lower rental income factor than the actual rent, typically between 75 and 80 per cent, to account for periods when the property is vacant or under repair. They also assess your tax position differently. If you currently negatively gear another property and plan to negatively gear the new one, the lender treats the net rental loss as an ongoing expense that reduces your serviceability.

Your deposit must be genuine savings or equity from an existing property. Lenders require at least 10 per cent of the purchase price as deposit if you are paying lenders mortgage insurance, or 20 per cent to avoid LMI altogether. If you are using equity from your home in Adelaide or another South Australian location, the lender will order a valuation on that security property as part of the pre-approval. That valuation determines how much equity you can access. A valuation that comes in $30,000 below your expectation can reduce your borrowing capacity by the same amount.

How long pre-approval lasts and when it expires

Most lenders issue pre-approval with a validity period of 90 days. Some extend to 120 days. The clock starts on the date the pre-approval is issued, not the date you apply. If you do not find a property and submit a full application with a signed contract within that window, the pre-approval expires and you need to reapply. Reapplying means the lender reassesses your income, debts and credit file under whatever credit policy is current at that time. If your income has dropped, your credit card limit has increased, or the lender has tightened policy, your borrowing capacity may fall.

Policy changes happen without warning. A lender may decide in June to reduce the rental income factor from 80 per cent to 75 per cent, or to stop accepting bonus income for borrowers in certain industries. Pre-approval locks in the policy settings that applied on the date it was issued, provided your circumstances have not changed and you submit a contract before expiry.

What happens after you find a property

Once you sign a contract, you return to your broker with the contract of sale and any additional documents the lender requires. The lender orders a valuation on the property you are purchasing. The valuation must meet or exceed the purchase price for the loan to proceed at the approved amount. If the valuation comes in below the contract price, the lender will only fund a loan based on the lower figure. You must find the shortfall from your own funds or renegotiate the purchase price.

The lender also conducts a final credit check and verifies that your financial position has not changed since pre-approval. If you have taken on new debt, changed jobs, or reduced your income, the lender may withdraw the offer or reduce the loan amount. This is why most brokers advise against applying for credit cards, car loans or other finance between pre-approval and settlement.

How South Australian investors can strengthen their pre-approval application

Start by reviewing your credit file at least 30 days before you apply. Errors on your file can delay or derail an application. If you hold credit cards you no longer use, close them before applying. Lenders assess credit card limits as if you have drawn the full amount, even if the balance is zero. A $15,000 limit can reduce your borrowing capacity by $80,000 or more depending on the lender's assessment rate.

If you are using equity from your current home, arrange a valuation through your broker before formal application. Knowing the value in advance allows you to calculate exactly how much deposit you can access and avoids surprises later. For buyers using genuine savings, ensure the funds have been in your account for at least three months. Lenders classify recent deposits as non-genuine savings unless you can prove the source with a separation certificate, inheritance documentation, or sale proceeds from another asset.

Brokers who work with investment loans regularly can identify which lenders are still within their debt-to-income cap for the month and which have tightened rental income policy. That insight is not visible to buyers applying directly. If you are refinancing an existing investment property while also seeking pre-approval for a new purchase, a broker can structure both applications to maximise your total borrowing capacity.

Interest rate options at pre-approval stage

You do not need to choose between variable and fixed rates at pre-approval. Lenders assess serviceability using their standard variable rate plus the 3 percentage point buffer, regardless of whether you eventually select a fixed rate product. Once your contract is unconditional and the valuation is complete, you can lock in a fixed rate if you prefer. Some investors split the loan, fixing a portion for rate certainty and leaving the remainder on a variable rate for flexibility. That decision does not affect the pre-approval itself.

Investors purchasing new builds may access a lower rate or waiver of certain fees. Lenders classify a property as a new build if it is purchased off the plan or constructed on vacant land. The definition does not extend to renovated properties or knock-down rebuilds unless the rebuild increases the total number of dwellings on the site. If your strategy involves new builds, confirm the classification with your broker at pre-approval stage so the correct product is applied when you proceed to formal approval.

When pre-approval does not guarantee final approval

Pre-approval is conditional. It assumes your financial position remains unchanged, the property you purchase is acceptable security, and the valuation supports the loan amount. Lenders can withdraw pre-approval if any of those conditions are not met. They can also withdraw it if their credit policy changes between pre-approval and formal application, although most honour the original decision if you submit the contract before expiry.

Properties that fall outside a lender's security policy will not be funded even with valid pre-approval. This includes units with commercial zoning, properties on land larger than 5 hectares, and dwellings the valuer considers unmarketable due to location, condition or building type. If you are considering a property in a regional South Australian location, confirm with your broker that your pre-approved lender will accept that postcode. Some lenders exclude towns with populations below a certain threshold or locations more than a set distance from a capital city.
