The easiest way to fund your property portfolio goals

Your property portfolio starts with the loan you arrange today.

Whether you're buying your first rental property or growing an established portfolio around Chapel Hill, the borrowing structure you put in place determines how quickly you can add properties, how much tax you can claim, and how much of your own cash you need each time. Get the structure right at the start and each property builds leverage for the next. Get it wrong and you lock yourself into a borrowing pattern that makes the second purchase harder than it needed to be.

How lenders calculate what you can borrow for a rental property

Lenders assess investment borrowing capacity differently to owner-occupied loans. They include rental income in your serviceability calculation, but they don't count all of it. Most lenders apply a rental income shading factor, typically 80 per cent, which means they assume you'll only receive four out of every five months of rent to account for vacancy periods and maintenance costs. They then add that shaded rental income to your other income and test whether you can service the loan at a rate at least 3.0 percentage points above the actual product rate.

Consider a buyer who finds a two-bedroom unit in Chapel Hill near the University of Queensland precinct, where rental demand stays fairly consistent. The property rents for $600 per week. The lender shades that to $480 per week for serviceability, which adds roughly $25,000 per year to the buyer's assessed income. If the buyer earns $95,000 in salary, their total serviceability income becomes $120,000. The lender then applies the 3.0 percentage point buffer on top of the loan rate, which at current variable rates can push the test rate above 9.0 per cent. That buffer alone can reduce borrowing capacity by 20 to 30 per cent compared to a calculation at the actual loan rate. The buyer also needs to factor in that their existing debts, including the mortgage on their own home, reduce how much they can borrow for the investment.

Interest-only or principal and interest repayments

Interest-only repayments keep your monthly outgoings lower and preserve cash flow, which matters when you're holding a property that costs more to run than it earns in rent. Principal and interest repayments build equity faster and reduce your loan balance over time, but they increase your monthly repayment by around 30 to 40 per cent compared to interest-only at the same rate.

Most lenders allow interest-only periods of up to five years on investment loans, after which the loan reverts to principal and interest for the remaining term. You can usually request another interest-only period at that point, subject to a fresh serviceability assessment. If you're planning to add another property within a few years, keeping the first loan on interest-only means your committed repayments stay lower, which leaves more serviceability available for the second purchase. If you're not planning further purchases and your priority is reducing debt, principal and interest from the start builds equity without requiring a later decision to switch.

Interest-only loans at LVRs above 80 per cent can attract higher risk weights under APRA's prudential framework, which means some lenders price them higher or decline them altogether. If you need to borrow above 80 per cent, check whether your lender differentiates pricing between interest-only and principal and interest structures at that LVR band.

Variable or fixed rates for investment property

Variable rates move with the market and let you make extra repayments or pay out the loan without penalty. Fixed rates lock in your repayment amount for a set period, usually one to five years, but they come with restrictions on extra repayments and can carry significant break costs if you pay out early or sell the property during the fixed term.

In our experience, buyers who fix their investment loan often do so to create certainty around cash flow, particularly when the rental income only just covers the loan repayment and holding costs. The problem arises when rates fall or when the buyer wants to access equity before the fixed term ends. Break costs are calculated based on the lender's funding cost difference between the fixed rate you're locked into and the rate they can now lend at for the remaining term. If you fixed at 6.0 per cent and rates have since dropped, breaking that loan two years into a five-year term can cost thousands of dollars, sometimes more than a year's worth of rental income.

Variable rates also allow you to link an offset account, which can reduce the interest you pay without technically making extra repayments. That distinction matters for tax purposes because the loan balance stays the same, so your deductible interest doesn't reduce, but the interest you actually pay does.

Using equity from your home to fund the deposit

Most buyers in Chapel Hill who add an investment property already own their home. Rather than saving a new cash deposit, they borrow against the equity in that home to fund the deposit and purchase costs for the rental property.

Lenders assess equity borrowing by calculating how much of your home's value remains unencumbered after your current mortgage is deducted. If your home is worth $900,000 and you owe $400,000, you have $500,000 in equity. Most lenders will let you access up to 80 per cent of the property's value without requiring LMI, which means you can borrow up to $720,000 in total across both loans. That leaves $320,000 available to access, enough to fund a deposit and costs on a property around the median price for units in the area.

The key constraint is serviceability. Releasing equity increases your total debt, and lenders test whether you can service both the increased loan on your home and the new investment loan at the same time. Even if the equity is available, you still need the income to support the additional borrowing. Structuring the equity release as a separate split or loan keeps the investment borrowing clearly separated from your private home loan, which makes record-keeping simpler and ensures the interest on the investment portion remains fully deductible.

How the debt-to-income limit applies to investors from February 2026

From 1 February 2026, APRA introduced a limit that restricts each lender to no more than 20 per cent of new investment lending going to borrowers with a total debt-to-income ratio of six times or higher. The limit applies separately to investment loans and owner-occupier loans, and it measures total debt against gross income.

For a buyer earning $120,000, a DTI of six times means total borrowing of $720,000. If that buyer already has $300,000 owing on their home and wants to borrow $450,000 for an investment property, their total debt reaches $750,000, pushing the DTI above six. That loan now falls within the 20 per cent cap. It doesn't mean the loan is automatically declined, but it does mean the lender has a limited quota for lending at that level, and they allocate it based on credit quality, deposit size, and overall risk.

Borrowers below the six-times threshold face no change. Bridging loans for owner-occupiers and loans for newly constructed dwellings are excluded from the cap. Non-bank lenders are not currently subject to the limit, which means they can still lend to borrowers above six times DTI without restriction, though their rates and fees may differ from ADI pricing.

What you can claim and when the new negative gearing rules begin

Interest on your investment loan is deductible against your rental income and other assessable income, along with council rates, insurance, property management fees, repairs and depreciation. If your deductible costs exceed your rental income, the loss can be offset against your salary or other income, reducing your overall tax.

That treatment continues unchanged for properties you held at 7:30pm AEST on 12 May 2026 or properties under contract at that time, and it also continues for newly constructed properties you buy after that date. For established properties purchased after 12 May 2026, losses from the 2027-28 income year onward can only be offset against income from residential properties, including capital gains on residential property. Excess losses carry forward to future years. If you bought an established investment property between 12 May 2026 and 30 June 2027, you can still claim the loss against all income until 30 June 2027, after which the new rules apply.

The CGT treatment also changes from 1 July 2027. Gains that accrue after that date will be taxed using cost base indexation and a 30 per cent minimum tax rate on the indexed gain, replacing the 50 per cent discount. For properties you already own, the gain is split between the portion that accrued before 1 July 2027, taxed under current rules, and the portion accruing after that date, taxed under the new rules. Newly constructed properties remain eligible for the 50 per cent discount regardless of when you sell them.

Structuring loans across multiple properties

Once you own more than one property, loan structure determines how much flexibility you have to sell, refinance or access equity later. The principle that matters most is keeping borrowings for each property separately identifiable so that the interest on each loan remains deductible against the income that loan was used to generate.

If you borrow $100,000 against your home to fund a deposit on an investment property, that $100,000 should sit in its own loan split or facility, separate from your private home loan. The interest on that split is deductible because the funds were used for investment purposes, even though the security is your home. If you later sell the investment property and use the sale proceeds to pay down your private home loan instead of the investment split, you'll still be paying interest on the investment split but you'll have no investment property generating income to claim it against. Structuring loans correctly at the start avoids that problem.

Refinancing across multiple properties also becomes more complex as your portfolio grows, particularly if you want to access equity in one property without disturbing the loan structure on another. Lenders assess your entire portfolio when you apply for a new loan or variation, so a property that was positively geared when you bought it can reduce your serviceability for future purchases if rents haven't kept pace with rate rises.

Your next decision depends on whether you're buying your first investment property or adding to an existing portfolio. If it's your first, the structure you arrange now needs to leave room for a second property later. If it's your second or third, the structure needs to preserve equity access and tax efficiency across all properties without forcing you to refinance everything each time you want to make a change.
