Top Strategies to Overcome Property Investment Challenges

Property Investment Loans Face Stricter Lending Rules

Borrowing capacity for investment property has tightened considerably. APRA requires lenders to assess serviceability at least 3.0 percentage points above the loan product rate, and from February 2026, banks may lend only up to 20 per cent of new investor loans to borrowers with a debt-to-income ratio of six times or greater. If your household income is $150,000 and you're seeking $900,000 in total home lending, you're at the six-times threshold, and any debt above that level places the application in the restricted 20 per cent allocation at most ADIs.

Consider an investor with an existing owner-occupied mortgage of $600,000 and household income of $130,000. Their total debt-to-income ratio is already 4.6. Adding a $300,000 investment loan would push the ratio to 6.9, which means the application competes for a limited allocation at each lender. Some applicants are approved within that allocation, others are declined or asked to reduce the loan amount, and the outcome often depends on timing and the lender's quarterly position against the limit.

The limits apply separately to the owner-occupier and investor lending portfolios of each institution and apply to new lending only. If you already hold an investment loan, the restriction does not affect your existing facility, but refinancing or topping up will be assessed under the current rules.

Calculating What You Can Borrow for Investment Property

Lenders assess your capacity to service an investment loan at an interest rate that is at least 3.0 percentage points above the loan product rate. If the variable rate on an investor loan is 6.5 per cent, the lender tests whether you can afford repayments at 9.5 per cent. Rental income is typically discounted by 20 per cent to account for vacancy, which means only 80 per cent of the expected rent is counted toward serviceability.

In a scenario where an investor is looking at a property with weekly rent of $800, the lender includes $640 per week in the serviceability calculation. The shortfall between the loan repayment at the assessment rate and the discounted rental income is added to your existing living expenses and other debt commitments. Your remaining surplus determines the maximum loan amount.

This is where borrowing capacity becomes a detailed exercise rather than a rough estimate. We regularly see investors who assume rental income will cover most of the loan repayment, only to find that the serviceability calculation leaves them $100,000 to $150,000 short of the amount required to proceed with the property they had in mind.

How Deposit and LVR Requirements Differ for Investors

Under APS 112, investor loans and interest-only loans generally attract higher risk weights than owner-occupied principal-and-interest loans at the same LVR. LMI is generally required by ADIs on residential loans where the LVR exceeds 80 per cent. Most lenders cap investor lending at 90 per cent LVR with LMI, and some cap it at 80 per cent depending on the applicant's profile and the property location.

An investor purchasing in an inner Sydney suburb such as Newtown or Marrickville will find that lenders apply standard metro postcode policies, but an investor looking at a regional or mining-exposed area may face a lower maximum LVR or outright exclusion from some lender panels. Location matters, and not just for rental yield.

Deposit is only part of the upfront cost. Stamp duty on investment property in New South Wales does not attract the concessions available to first home buyers or owner-occupiers purchasing below the relevant threshold. Legal fees, building and pest inspections, and LMI premiums if applicable all add to the capital required at settlement.

Interest Only Versus Principal and Interest Repayments

A long-term interest-only residential loan is classified as non-standard where the LVR is greater than 80 per cent and the contractual interest-only period is greater than five years or is not specified. Most lenders offer interest-only periods of up to five years on investment loans, and the loan must revert to principal and interest after that term unless an extension is approved.

An interest-only structure reduces the monthly cash outflow during the initial holding period and may improve short-term serviceability, but it does not reduce the loan balance. If an investor is relying on capital growth to refinance or sell within a few years, the interest-only period can align with that strategy. If the intention is long-term hold and portfolio growth, principal and interest repayments build equity over time and reduce exposure to rate movements.

In our experience, the decision depends on cash flow requirements and broader portfolio structure. An investor with multiple properties may use interest-only on one loan to free up serviceability for the next purchase, while keeping other loans on principal and interest to reduce overall debt. There is no universal formula, and the choice should be documented within a property investment strategy rather than selected by default at application.

Tax Changes Affecting Investment Property from 2027

From the 2027-28 income year, losses related to established residential investment properties acquired after 7:30pm AEST on 12 May 2026 are deductible only against other income from residential properties, including capital gains on residential properties. Excess losses can be carried forward to offset residential property income in future years. Properties purchased before that date retain full negative gearing, as do eligible new builds purchased after that date.

From 1 July 2027, the 50 per cent CGT discount for individuals, trusts and partnerships on affected assets is replaced by cost base indexation using CPI and a 30 per cent minimum tax rate on real capital gains accruing from that date. For assets owned before 1 July 2027 and sold after that date, gains are taxed under the current rules for the portion accruing before 1 July 2027 and under the new rules for the portion accruing after that date.

Consider an investor who exchanged contracts on an established apartment in Pyrmont in April 2026 and settled in June 2026. That property retains full negative gearing and the 50 per cent CGT discount on gains accruing up to 1 July 2027, with the new indexation rules applying to gains from that date forward. An investor purchasing an established townhouse in Rozelle in August 2026 can only offset rental losses against other residential property income from the 2027-28 income year onward.

These changes have shifted the financial modelling for many Sydney investors. Where negative gearing previously improved after-tax cash flow from year one, investors purchasing established property now need either positive cash flow from the outset or other residential property income to absorb the loss. The change does not prevent investment, but it does require more capital or a different property selection to make the numbers work.

Refinancing Investment Loans After Rate Increases

Many investors who fixed their loans in 2020 or 2021 have already rolled onto variable rates that are 2.5 to 3.5 percentage points higher than their previous fixed rate. Those who are still within a fixed term may face break costs if they exit early, and those who have rolled off are now managing higher repayments.

Refinancing an investment loan involves a full serviceability assessment under current rules, including the 3.0 percentage point buffer and the debt-to-income limit. If your income or circumstances have changed since the original loan was approved, or if you have taken on additional debt, you may not qualify for the same loan amount under the current criteria. This has created a situation where some investors are unable to refinance to a lower rate because their current loan amount exceeds what they would be approved for today.

The alternative is to stay with the existing lender and negotiate a rate adjustment without a full refinance. Many lenders will reduce rates for existing customers as a retention measure, particularly where the loan is performing and the customer raises the possibility of moving elsewhere. The discount may not match the headline rate available to new customers, but it avoids a fresh serviceability test and the risk of a declined application.

When Rental Income Alone Is Not Enough

Lenders assess serviceability at least 3.0 percentage points above the loan product rate, and rental income is typically discounted by 20 per cent. An investor relying entirely on rental income to service an investment loan will find that the rental yield must be high enough to cover the assessed repayment after the 20 per cent discount is applied.

For a loan amount of $600,000 assessed at 9.5 per cent on a principal and interest basis over 30 years, the monthly repayment at the assessment rate is approximately $5,050. To cover that amount, the property would need to generate rent of roughly $1,450 per week before the shading is applied. That rental level is uncommon for a property at that price point in most Sydney suburbs, which means the investor's other income must cover the shortfall.

Investors with multiple properties face compounding serviceability pressure. Each additional loan adds to the total debt servicing requirement, and the discounted rental income from each property rarely covers the full assessed repayment. This is one reason portfolio growth slows after two or three properties unless the investor increases income, pays down debt, or uses equity release in a way that does not trigger a full serviceability reassessment.

Choosing the Right Loan Structure for Your Portfolio

Loan features matter more than rate alone. Offset accounts, redraw facilities, portability, and the ability to split the loan between fixed and variable portions all affect how the loan performs over time. Offset account balances do not reduce the loan amount for LVR purposes under APS 112. The balance does reduce the interest charged, but it does not change the loan-to-value ratio used by the lender when assessing risk or calculating LMI.

An investor holding cash in an offset account linked to an investment loan reduces the deductible interest. If tax deductions are a priority, it may be more effective to hold surplus cash in an offset account against a non-deductible owner-occupied loan and leave the investment loan balance untouched. This requires separate loan structures, and many investors find that splitting loans by purpose at the outset avoids the need to refinance later to restore deductibility.

Investment loan products vary significantly between lenders. Some offer interest rate discounts for portfolio customers or professional packages, others impose higher rates but allow more flexible serviceability treatment or higher LVRs. Accessing a panel of lenders rather than a single bank increases the chance of finding a product that aligns with your specific circumstances and the property type you are purchasing.
