Understanding the basics of owning multiple properties

How Borrowing Power Changes with Each Property

Your borrowing power reduces with each investment property you add because lenders assess rental income at a discount, typically 80 per cent of the expected rent to allow for vacancies and maintenance costs. Banks also test your ability to service all loans at an interest rate at least 3 percentage points above the actual rate.

Consider a buyer who already owns a home in Nowra and wants to add a first rental property. If the proposed property would rent for $500 per week, the lender counts only $400 of that towards income when calculating how much you can borrow. That $100-per-week reduction compounds across multiple properties. Someone with three rentals generating $1,500 per week combined will see only $1,200 counted, leaving $300 per week or roughly $65,000 in borrowing power sitting outside the lender's calculation.

From 1 February 2026, banks can lend no more than 20 per cent of their new investor loans to borrowers with a debt-to-income ratio of six times or greater. If your total debt across all mortgages is more than six times your gross household income, some lenders will decline the application outright while others may still consider it within their limited quota. Speaking with a broker who works across multiple lenders gives you a clearer picture of where capacity still exists.

Using Equity from Existing Properties as Your Deposit

Most investors beyond their first property use equity rather than cash savings to fund the next purchase. Equity is the difference between what your property is worth and what you owe on it. Lenders allow you to borrow against that equity up to a certain loan-to-value ratio, typically 80 per cent without paying for Lenders Mortgage Insurance.

If your Nowra home is worth $650,000 and you owe $300,000, you have $350,000 in equity. At 80 per cent LVR, the lender will allow total lending of $520,000 across that property, leaving $220,000 available to draw. After holding back a buffer for costs, that might give you $200,000 towards the next purchase. The original loan stays in place and you take a second loan secured against the same property, or you refinance into a single larger facility. Both structures work, and the right choice depends on your rate, features and whether you want to keep loans separate for clarity.

Keep in mind that refinancing to access equity can also be an opportunity to review your current rate and loan structure across the whole portfolio, particularly if your existing loans are no longer offering the features or discounts you need.

Interest-Only Loans and Cash Flow Across Multiple Properties

Interest-only repayments are common for investors because they lower the monthly cost and leave more cash available to service the next loan or cover holding costs. The loan balance does not reduce during the interest-only period, but the property may still increase in value, building equity you can access later.

A typical interest-only period is five years, after which the loan converts to principal and interest unless you apply to extend it. Lenders assess interest-only extensions on a case-by-case basis and some will decline if your circumstances have changed or if you have multiple interest-only loans already. Where the loan-to-value ratio exceeds 80 per cent and the interest-only period is longer than five years or unspecified, the loan is treated as non-standard under prudential rules, which means higher capital costs for the lender and often a higher rate or stricter assessment for you.

If you are holding several properties on interest-only terms and approaching the end of those periods, it is worth reviewing your options early rather than waiting for the automatic conversion. Some investors move one property to principal and interest to demonstrate serviceability, then apply to extend interest-only terms on others. That approach can help manage cash flow without losing flexibility across the whole portfolio.

How the Tax Changes from 2027 Affect Multi-Property Investors

Properties owned at 7:30pm AEST on 12 May 2026, or under contract at that time, continue to allow full deduction of losses against all income including wages. For established properties purchased after that date, losses from 1 July 2027 onwards can only be offset against other residential property income, including capital gains on residential properties.

This creates a clear difference between properties in your portfolio depending on when you bought them. If you acquired two rentals in Nowra before May 2026 and buy a third established property now, the first two will continue to deliver full negative gearing benefits while the third will quarantine losses from the 2027-28 income year. Those quarantined losses carry forward and can offset income from any of your rental properties in future years, or be applied against capital gains when you sell.

Eligible new builds remain fully deductible regardless of purchase date. That includes new homes on vacant land and developments that increase the number of dwellings on a site. Knock-down rebuilds that do not increase dwelling numbers are not counted as new builds under the exemption.

For investors holding multiple properties and planning to expand, the tax treatment now plays a bigger role in the decision between buying established homes close to Nowra's CBD and shopping centres, or looking at new builds slightly further out where supply is increasing.

Structuring Loans When You Own More Than One Property

Some investors keep each property on its own loan, while others consolidate where it makes sense. Separate loans give you clarity around which property is costing what, and they make it easier to sell one property and discharge just that loan without restructuring everything. The downside is more accounts to manage and potentially higher fees.

If you have built enough equity, you might consolidate loans against one or two properties to access a lower rate or better features. The risk is that selling one property later does not automatically release a neat portion of debt. You will need to refinance or redraw, and the lender reassesses serviceability at that point.

Cross-collateralisation is another structure where the lender holds security over multiple properties under one facility. It can make approval easier when you are borrowing at higher levels, but it also means the lender has a charge over all properties in the pool. If one loan defaults, the lender can pursue any property in the group. Most brokers recommend keeping properties with different lenders or at least on separate loan contracts where possible, so you retain control and flexibility as the portfolio grows.

You can review your current loan structure and whether it still fits your plans through a loan health check, particularly if your portfolio has grown or your goals have shifted since you first borrowed.

Vacancy Rates and Rental Income in Nowra

Nowra sits in the Shoalhaven local government area, which includes a mix of retirees, families and workers tied to the local defence and healthcare sectors. Rental demand has remained relatively steady, supported by limited new housing supply and ongoing population growth along the South Coast. Properties close to Nowra Hospital, the Stockland Nowra shopping centre and schools in suburbs like Bomaderry and North Nowra tend to attract longer-term tenants, which helps reduce turnover costs.

Lenders apply a vacancy and maintenance buffer when calculating rental income, usually 20 per cent, so a property renting for $450 per week is assessed at $360. In practice, if you are holding multiple properties, even one extended vacancy can affect your ability to service all loans comfortably. Keeping a cash buffer equal to three to six months of combined repayments gives you room to cover gaps without needing to sell in a hurry.
