Smart ways to approach multiple investment properties

There is no legal limit to the number of investment properties you can own in Templestowe Lower or anywhere else in Australia.

What constrains most investors is not regulation but serviceability. Lenders assess whether your income can support the debt on all existing properties plus the new one you want to acquire. That calculation becomes more restrictive with each property you add, particularly when rental income is shaded and expenses are factored in.

How Lenders Assess Serviceability Across Multiple Properties

Lenders typically assess rental income at 70% to 80% of the actual rent received. If you own a townhouse in Templestowe Lower generating $550 per week, the lender might only count $385 to $440 of that income when calculating what you can afford to borrow. At the same time, they add the full loan repayment, plus an interest rate buffer of around 3%, plus estimates for property expenses including body corporate fees, council rates, and maintenance.

Consider an investor who owns two properties already and wants to purchase a third in the Templestowe Lower area near Reynolds Road. Their existing loans total $900,000 across two properties, with combined rental income of $1,100 per week. After the lender applies an 80% shading factor, that income is assessed at $880 per week. The investor earns $140,000 annually in salary. When the lender runs serviceability, they calculate repayments on all loans at a buffered rate around 6% higher than the actual rate, then deduct living expenses based on the Household Expenditure Measure. Even with strong employment income, the shaded rental income and cumulative debt servicing can limit how much additional borrowing capacity remains for a third property.

The Role of Equity and Loan to Value Ratio

Most lenders cap investor loans at 80% LVR without requiring Lenders Mortgage Insurance, though some will lend to 90% LVR if you pay the premium. As your portfolio grows, lenders also apply portfolio caps. Some institutions limit exposure to four financed investment properties. Others allow more but tighten servicing or require lower LVRs on subsequent purchases.

If you already own three investment properties and want to acquire a fourth, the lender may insist on 75% LVR or lower, even if you have sufficient equity. This protects the lender's overall exposure to your portfolio and to the investment property sector more broadly.

Interest Only Versus Principal and Interest Repayments

Many investors use interest only repayments to improve cash flow and preserve serviceability for future purchases. An interest only loan on a property with a $500,000 balance might require monthly repayments around $2,100 at current variable rates, compared to $3,200 on principal and interest over 30 years. That difference of $1,100 per month directly affects how much debt the lender believes you can service.

However, interest only periods are typically limited to five years, after which the loan reverts to principal and interest unless you refinance or negotiate an extension. Lenders assess your ability to service the loan at principal and interest rates even if you intend to stay interest only. This means the cash flow benefit exists, but it does not allow you to borrow significantly more than you could on a principal and interest loan when serviceability is calculated.

Cross-Collateralisation and Portfolio Structure

Some lenders encourage cross-collateralisation, where multiple properties are used as security under a single loan facility. This can simplify administration but reduces flexibility. If you want to sell one property or refinance a specific loan, you need the lender's consent to release that security, which can delay transactions or limit your ability to move properties between lenders.

Investors building portfolios in Templestowe Lower and surrounding areas often structure loans so each property sits with a separate lender or at least under separate loan contracts. This allows you to refinance one property to release equity without affecting the others. It also spreads risk across multiple institutions, which can be useful if one lender tightens policy or declines further lending.

Rental Income Verification and Vacancy Assumptions

Lenders require lease agreements and sometimes rental statements to verify income. If a property is vacant at the time of application, most lenders will accept a rental appraisal from a licensed agent, though some apply a further discount or exclude that income entirely until a tenant is in place.

Templestowe Lower has a relatively low vacancy rate due to its proximity to schools, parks along the Yarra River, and transport links into the CBD. However, lenders do not typically adjust their shading policies based on local vacancy rates. They apply a standard percentage regardless of whether the property is in a high-demand suburb or a regional area with longer vacancy periods.

Tax Deductions and Negative Gearing Considerations

Negative gearing allows you to offset the loss from an investment property against your other taxable income. Interest on the investment loan, property management fees, insurance, rates, and depreciation are all claimable expenses. For an investor in Templestowe Lower holding multiple properties, these deductions can reduce taxable income substantially, though they do not change the lender's serviceability calculation.

Lenders assess your pre-tax income and do not give credit for the tax benefit of negative gearing when determining how much you can borrow. This can create a mismatch where the investment is financially viable after tax but appears unaffordable in the lender's assessment.

Practical Limits on Portfolio Size

Most investors in the Templestowe Lower area reach a ceiling at three to five financed properties. Beyond that point, even high-income earners with substantial equity find it difficult to satisfy serviceability requirements without restructuring debt, increasing rent, or reducing personal expenses.

Some investors move to commercial lending structures once they own multiple properties, particularly if they hold assets through a trust or company. Commercial lenders assess the portfolio's income-generating capacity rather than personal serviceability, though these loans typically require higher deposits and carry different fee structures.

If you are approaching the limits of what traditional lenders will support, speaking with a mortgage broker who understands investment loan options across multiple lenders can identify institutions with higher portfolio caps or more flexible servicing policies.
