Comparing Investment Loans When Most Properties Are New Builds
Truganina's property market is dominated by new construction, which changes how you should compare investment loan products. Most of the homes and townhouses hitting the market were built within the last five years, and lenders treat new builds differently when it comes to loan features, valuations, and ongoing flexibility.
Consider a property investor looking at a three-bedroom townhouse in one of the estates near Forsyth Road. The property is less than two years old, strata-titled, and part of a large development that's still being completed in stages. When comparing loans for this purchase, the investor needs to account for how lenders assess rental income in areas with high vacancy rates during construction phases, how body corporate fees affect borrowing capacity, and whether the lender will value the property based on comparable sales or the contract price. These aren't concerns you'd face buying an established home in older suburbs, but they're central to any investment decision in Truganina.
The first thing to compare across lenders is how they treat rental income assumptions. Some lenders will shade your expected rental income by 20% when calculating serviceability, while others apply a 25% buffer. On a property returning $420 per week, that difference changes how much you can borrow by several thousand dollars. You'll also want to confirm whether the lender requires actual rental income or accepts a rental assessment based on comparable properties, particularly if you're buying off-the-plan or the property is still under construction.
Interest Rate Structure and What It Means for Cash Flow
Variable and fixed rates serve different purposes depending on whether you're relying on rental income to cover repayments or holding the property as a long-term wealth-building strategy. A variable rate gives you flexibility to make extra repayments and access features like offset accounts, which can reduce the interest you're charged without locking you into a fixed term. A fixed rate offers certainty, but limits your ability to adjust repayments or refinance without incurring break costs.
For an investment loan on a Truganina property, most investors in the area lean toward variable rates or a split structure because rental income doesn't always cover the full loan repayment in the early years, and the ability to make lump sum payments from other income sources without penalty becomes important. If you're buying in one of the newer estates near Westbrook Avenue and expect rental demand to tighten as construction completes, a variable rate lets you pivot your repayment strategy without waiting for a fixed term to expire.
Interest-only repayments are another feature worth comparing. Paying interest only for the first few years keeps your repayments lower and can improve your cash flow, particularly if you're negatively geared. That said, interest-only periods are typically capped at five years, and you'll need to be prepared for repayments to increase once the principal and interest period begins. Not all lenders offer the same interest-only terms, and some will price interest-only loans higher than principal and interest from the outset.
Loan to Value Ratio and How It Affects Your Upfront Costs
Your deposit size directly determines whether you'll pay Lenders Mortgage Insurance and what interest rate you'll be offered. Lenders price investment loans on a tiered structure based on loan to value ratio. Borrowing 80% or less typically avoids LMI and attracts a lower rate. Borrowing between 80% and 90% triggers LMI, and some lenders will add a rate loading or restrict certain features like interest-only repayments.

In a scenario where you're purchasing a townhouse in Truganina and borrowing 85% of the property value, you might be quoted a rate that's 0.15% to 0.30% higher than an investor borrowing 75%. Over a loan amount of $450,000, that difference adds several hundred dollars per year in interest costs. Some lenders also cap investment lending at 80% LVR for new builds in growth corridors, so confirming the maximum LVR upfront is important before you commit to a property.
If you're using equity from an existing property to fund the deposit, you'll want to compare how lenders assess cross-securisation and whether they'll allow you to keep the properties on separate loan accounts. Keeping loans separate gives you more flexibility to refinance or sell one property without affecting the other, but not all lenders structure their lending this way.
Offset Accounts and Redraw Facilities
An offset account linked to your investment loan reduces the interest you're charged without requiring you to make extra repayments into the loan itself. If you keep $15,000 in a 100% offset account and your loan balance is $400,000, you're only charged interest on $385,000. This is particularly useful if you're holding surplus rental income or savings that you want to keep accessible while still reducing your interest costs.
Not all lenders offer offset accounts on investment loans, and some will charge an annual fee or only provide a partial offset. A partial offset means the balance in your account only offsets a percentage of the loan balance, which dilutes the benefit. When comparing loan products, confirm whether the offset is full or partial, whether there's a fee, and whether the account can be linked to multiple loans if you're building a property portfolio.
Redraw facilities allow you to access any extra repayments you've made into the loan, but they're less flexible than offset accounts because the funds are held within the loan itself. Some lenders also restrict how often you can redraw or charge a fee per transaction. For investors who want regular access to surplus funds, an offset account is usually the better option.
Lender Policies on Rental Income and Serviceability
How a lender calculates your borrowing capacity for an investment property can vary significantly, particularly in suburbs like Truganina where vacancy rates fluctuate as new estates are completed. Most lenders will assess rental income at 80% of the market rate to account for periods when the property is vacant or between tenants. Some lenders use 75%, which reduces how much you can borrow by a noticeable margin.
If the property is tenanted at the time of application, some lenders will accept the actual lease agreement as evidence of rental income, while others will still shade the income regardless of what the tenant is paying. This becomes relevant if you're refinancing an investment property that's already generating income and you want to leverage that income to borrow more.
You'll also need to compare how lenders treat other debts and living expenses when calculating serviceability. Some lenders apply the Household Expenditure Measure, which uses a standardised estimate of your living costs based on your household size and income. Others will assess your actual declared expenses. If you have low living costs or share expenses with a partner, the HEM approach might work in your favour.
Flexibility to Expand Your Portfolio Over Time
If you're planning to buy more than one investment property, you'll want to compare how lenders assess subsequent purchases and whether they have portfolio limits. Some lenders cap the number of investment properties they'll finance for a single borrower at four or five, while others have no formal limit but tighten serviceability as your portfolio grows.
Truganina investors who start with a single townhouse and plan to buy additional properties in nearby suburbs like Point Cook or Werribee need to confirm that the lender they choose today won't restrict their ability to borrow again in two or three years. Portfolio lending policies aren't always advertised upfront, so asking about this during the comparison stage can save you from needing to refinance later just to access more borrowing capacity.
Some lenders also offer better rate discounts or waive fees for borrowers with multiple loans, which can make staying with the same lender more attractive as your portfolio grows. Others price each loan independently, in which case you're better off refinancing to a new lender each time if it means securing a lower rate.
How the 2026 Budget Changes Affect Your Loan Comparison
The Federal Budget introduced changes to capital gains tax and negative gearing that apply to established residential properties purchased after 12 May 2026. If you're buying in Truganina and most of the available stock is new construction, you're less affected than investors targeting established homes in older suburbs. New builds retain the 50% CGT discount and full negative gearing deductions, which improves the after-tax return compared to buying an older property under the new rules.
This doesn't change how you compare interest rates or loan features, but it does shift the financial modelling around which properties make sense to buy. If you were considering an established home in a neighbouring suburb versus a new townhouse in Truganina, the tax treatment now favours the new build more heavily. When comparing loans, you'll want to factor in whether the property qualifies for the grandfathered tax treatment and how that affects your projected returns over the hold period.
Ongoing Fees and What They Add Up To
Annual fees, monthly account-keeping fees, and package fees can add hundreds of dollars per year to the cost of your loan, and they're easy to overlook when you're focused on comparing interest rates. Some lenders charge $395 per year for an investment loan package that includes an offset account and rate discount. Others charge no annual fee but don't offer an offset or waive other costs.
When comparing products, calculate the total cost over the first few years including all fees, not just the interest rate. A loan with a 0.10% higher rate but no annual fee might cost less overall than a loan with a lower rate and a $395 package fee, depending on your loan balance.
Some lenders also charge a higher upfront application or settlement fee for investment loans compared to owner-occupier loans. Truganina investors should confirm these costs before applying, particularly if you're buying a property with settlement costs that already include stamp duty and conveyancing.
Rate Discounts and How to Access Them
Most lenders advertise a standard variable rate but offer discounts based on your loan size, LVR, and whether you're a new or existing customer. A discount of 0.50% to 1.00% off the standard rate is common, but not automatic. You'll often need to ask for the discount or apply through a broker who has access to better pricing.
Investors borrowing larger amounts or holding multiple loans with the same lender are usually eligible for deeper discounts. If you're borrowing $500,000 or more for a Truganina property, confirm what rate discount applies at that loan amount and whether it increases further at higher thresholds. Some lenders also offer bonus rate reductions if you hold a transaction account or deposit a portion of your rental income with them, though these conditions can reduce your flexibility.

Frequently Asked Questions
What loan to value ratio should I aim for when buying an investment property in Truganina?
Borrowing 80% or less avoids Lenders Mortgage Insurance and typically attracts a lower interest rate. Some lenders cap investment lending at 80% LVR for new builds in growth areas, so confirming the maximum LVR upfront is important.
How do lenders assess rental income for an investment property?
Most lenders shade your expected rental income by 20% to 25% when calculating serviceability to account for vacancy periods. Some will accept a signed lease as evidence, while others apply the shading regardless of actual rental income.
Should I choose a variable or fixed rate for an investment loan?
Variable rates offer flexibility to make extra repayments and access offset accounts, which suits investors who want to adjust their strategy over time. Fixed rates provide repayment certainty but limit flexibility and may incur break costs if you refinance early.
Do the 2026 Federal Budget changes affect investment loans for new builds in Truganina?
New builds retain the 50% CGT discount and full negative gearing deductions, so the recent changes to capital gains tax and negative gearing don't apply. Established properties purchased after 12 May 2026 are subject to the new rules from 1 July 2027.
What's the difference between an offset account and a redraw facility?
An offset account reduces the interest charged on your loan without locking funds inside the loan itself, giving you full access to your money. A redraw facility allows you to access extra repayments you've made, but the funds are held within the loan and may have transaction fees or limits.
