Different property types require different financing approaches.
Air Force members considering property investment face specific decisions about what to buy based on deployment schedules, posting cycles, and the need for rental income while serving. The property type you choose determines your deposit requirements, interest rate structure, and eligibility for certain loan features. Understanding these differences before you apply means you can match your investment strategy to both your service commitments and your financial position.
Established Residential Properties and Standard Loan Products
Established houses and units typically offer the most straightforward path to investment loans for ADF members. Banks and lenders assess these properties based on known values and rental histories. The loan to value ratio usually sits at 80% without Lenders Mortgage Insurance for most defence force borrowers, though some lenders extend this to 90% for serving members.
Consider an Air Force technician based at Williamtown purchasing a three-bedroom house in Newcastle. The property costs $650,000 with comparable rentals achieving $550 per week. At 80% LVR, the deposit required is $130,000. The lender assesses rental income at 80% of market rent to account for vacancy periods and maintenance costs, calculating serviceability on $440 per week or approximately $22,880 annually. This property type allows both variable and fixed rate options, with interest only repayment structures available for up to five years initially.
The vacancy rate calculation matters here. Residential properties in established suburbs near defence bases typically show lower vacancy periods than properties in regional centres or mining towns. This affects both your cash flow planning and how lenders assess your borrowing capacity.
Units with Body Corporate Structures
Units and apartments introduce body corporate fees into the equation. Lenders subtract these fees from rental income when calculating serviceability, which reduces your borrowing capacity compared to a standalone house at the same purchase price.
In a scenario where you're looking at a two-bedroom unit near RAAF Base Richmond priced at $520,000 with body corporate fees of $1,800 per quarter, those fees represent $7,200 annually. If market rent sits at $480 per week, the lender assesses income at $19,968 after applying the 80% rental factor, then subtracts the $7,200 in fees. Your net assessed rental income becomes $12,768, which is what the lender uses for serviceability calculations. The body corporate fee structure directly impacts how much you can borrow, not just your net return.

Some lenders cap loan amounts on apartments above certain floors or in buildings with specific construction types. This particularly affects newer high-rise developments in capital cities where combustible cladding or defect issues have emerged. Your property investment loan application might be approved at a lower amount than expected, or require a larger deposit, based purely on the building characteristics rather than your financial position.
Interest Only Versus Principal and Interest for Property Investors
Interest only repayment structures reduce your monthly outgoings during the initial loan period, which helps if your rental income doesn't cover the full loan repayment plus property costs. Most lenders offer interest only periods between one and five years on investment property finance, after which the loan converts to principal and interest.
The calculation difference is substantial. On a $500,000 investment loan at current variable rates, interest only repayments might sit around $2,300 per month. Converting to principal and interest over the remaining 25-year term increases repayments to approximately $3,100 per month. That $800 monthly difference needs to be factored into your strategy from the outset.
Air Force members frequently use interest only structures during posting periods when they're renting elsewhere themselves. The lower repayment allows them to maximise tax deductions through negative gearing benefits while maintaining cash flow. When they return to a home base or reduce service commitments, switching to principal and interest builds equity and reduces debt over time.
Purchasing Off-the-Plan or New Construction Properties
Off-the-plan purchases and new builds operate differently to established properties. Lenders typically require a 10% deposit on exchange, with the balance due at settlement, which might occur 12 to 24 months later. Your deposit sits in trust during construction, but your borrowing capacity gets assessed at application.
The valuation risk sits with you. If the property values at less than the purchase price at settlement, you'll need to find the difference or renegotiate your deposit. During your construction period, interest rates may also shift. If you've locked in a fixed rate at application, most lenders allow this to stand if settlement occurs within the rate lock period. Outside that window, you're subject to current rates at settlement.
New property purchases offer depreciation benefits that established properties don't. Building components and fixtures can be claimed as tax deductions over time, which improves your after-tax return. However, rental demand for brand new stock needs careful assessment. Multiple settlements in the same development can flood the rental market simultaneously, increasing vacancy rates in that immediate period.
Variable Rate and Fixed Rate Considerations for Different Property Types
Your choice between variable and fixed interest rates connects directly to your property type and investment timeframe. Variable rates allow offset accounts, which helps manage cash flow if your posting schedule creates irregular income periods or you're building funds for future portfolio growth.
Fixed rates lock in your repayment amount, which aids budgeting during deployments or training periods when you're managing finances remotely. However, fixed rate products typically don't permit offset accounts, and extra repayments are usually capped. For Air Force members expecting rental income to cover most costs, a variable rate with offset functionality often provides more flexibility than a fixed rate, even if the fixed rate sits slightly lower.
Some property investors split their loan between fixed and variable portions. Half the loan amount might be fixed for three years while the other half remains variable with an offset account attached. This structure provides rate certainty on a portion of the debt while maintaining flexibility on the rest.
Leveraging Equity for Portfolio Growth
Once your first investment property builds equity, you can access that equity to fund deposits on additional properties without selling. Equity release loans for ADF members allow you to borrow against the increased value of your existing property while keeping that property in your portfolio.
If your Newcastle property purchased at $650,000 increases in value to $750,000 over several years while you've paid the loan down to $480,000, you've built $270,000 in equity. Lenders typically allow you to access up to 80% of the property value, which is $600,000. Subtracting your existing $480,000 loan leaves $120,000 in accessible equity. This amount can fund a deposit on a second property without requiring you to save additional cash.
The calculation changes when you're expanding your property portfolio because lenders assess all investment properties together. Each additional property adds rental income and debt to your serviceability assessment. The more properties you hold, the more conservative lenders become about vacancy rates and rental income calculations. Your fifth investment property will face stricter serviceability tests than your first.

Frequently Asked Questions
What deposit do I need for an investment property as an Air Force member?
Most lenders require a 20% deposit for investment properties to avoid Lenders Mortgage Insurance, though some extend to 10% for serving defence force members. The deposit requirement can increase for units in certain buildings or off-the-plan purchases depending on the lender's assessment.
How do body corporate fees affect my investment loan application?
Lenders subtract body corporate fees from your rental income when calculating serviceability. Higher fees reduce the net rental income used in your application, which directly lowers your borrowing capacity compared to a house without these fees.
Should I choose interest only or principal and interest for my investment property loan?
Interest only repayments are lower and help with cash flow during posting periods or when maximising negative gearing benefits. Principal and interest repayments build equity faster and reduce your total debt over time, which suits members closer to transitioning out of service.
Can I use equity from my first investment property to buy a second one?
You can access equity once your property increases in value or your loan balance reduces. Lenders typically allow borrowing up to 80% of the property value, and the difference between this amount and your existing loan can fund a deposit on another property.
What's the difference between buying an established property and an off-the-plan property?
Established properties offer known values and immediate rental income, with straightforward loan approval processes. Off-the-plan purchases require deposits upfront with settlement 12 to 24 months later, introducing valuation risk and potential rate changes but offering depreciation benefits.
