The easiest way to buy off-the-plan as an Air Force member

Why off-the-plan purchases suit Air Force members

Off-the-plan properties let you lock in a price today and settle months or years later. You pay a deposit now, the developer builds the property, and you settle when construction finishes. For Air Force members, this means you can secure a property while posted to one location and time settlement to align with your next posting or when you're ready to move in.

The deposit structure typically involves a 10% deposit at contract exchange, though you may negotiate staged payments during construction. Settlement occurs when the property reaches practical completion and the developer obtains the title. The time between contract and settlement usually ranges from 12 to 24 months depending on the development.

How the Australian Government 5% Deposit Scheme works for off-the-plan purchases

The Australian Government 5% Deposit Scheme removes the need for a 20% deposit and eliminates lenders mortgage insurance. You contribute 5% of the purchase price, and Housing Australia guarantees the remaining 15% to bring your total security to 20%. No income caps apply, and applications are unlimited. You apply through one of 31 participating lenders, not directly through Housing Australia.

Property price caps vary by location. Sydney properties must be under $1,500,000, Melbourne under $950,000, and Brisbane under $1,000,000. Regional caps increased from October 2025 and differ by region. The scheme works with off-the-plan contracts as long as the property price at settlement stays within the cap for your location.

Consider an Air Force member based at RAAF Base Richmond who signs a contract for an off-the-plan apartment in Western Sydney at $750,000. With a 5% deposit, they pay $37,500 at contract exchange. During the 18-month construction period, they continue renting near base. When the property reaches practical completion, they settle using the 5% Deposit Scheme, avoiding lenders mortgage insurance and keeping their savings intact. The apartment becomes an owner-occupied property immediately, or they rent it out if their posting changes before settlement.

The scheme applies to both new and established properties, but off-the-plan purchases fall under the new property category. You cannot combine the 5% Deposit Scheme with Help to Buy, though you can use it alongside most state and territory stamp duty concessions and grants. Check with your mortgage broker to confirm which combinations work in your state.

State grants and stamp duty concessions for off-the-plan buyers

Most states offer higher grants for new properties compared to established homes, and off-the-plan purchases qualify as new. In Queensland, eligible first home buyers receive a $15,000 grant for new homes valued under $750,000 when contracts are signed from 1 July 2026. New builds attract full transfer duty concessions with no price cap on residential land from 1 May 2025.

In New South Wales, the First Home Owner Grant provides $10,000 for new builds or substantially renovated homes with a purchase cap of $600,000 or a land and build cap of $750,000. Stamp duty exemptions apply in full for properties up to $800,000, with concessions phasing out at $1,000,000.

Victoria offers a specific off-the-plan concession for strata or community title contracts signed on or before 31 October 2026. Duty is calculated on land value at contract date only, not on the completed property value. This concession applies to a broader group of buyers, not just first home buyers, during the eligible period. The standard first home buyer stamp duty exemption still applies in full for properties up to $600,000, with concessions from $600,001 to $750,000.

The Australian Capital Territory removed both property value limits and income thresholds from 1 July 2026. Eligible buyers are now fully exempt from conveyance duty regardless of property value or household income. A separate off-the-plan unit duty exemption applies from the same date with no property value threshold for unit-titled properties like apartments and townhouses. You must occupy the property as your principal place of residence continuously for at least one year commencing within 12 months of completion.

How deposit structures differ from established property purchases

Off-the-plan deposits usually follow a staged payment schedule rather than a single lump sum. A typical structure involves 10% at contract exchange, split into an initial payment of 5% and a second payment of 5% within 30 to 90 days. Some developers request further progress payments during construction, though this varies by project.

Your lender assesses your borrowing capacity at application, but the formal loan approval often occurs closer to settlement. Interest rates and lending criteria at settlement may differ from those at contract exchange. Most lenders issue conditional approval early and then reassess closer to practical completion. If rates have risen or your circumstances have changed, your borrowing capacity may be affected.

You need genuine savings for the deposit unless you're using a family guarantee or gift funds. Most lenders require at least 5% of the purchase price to come from savings held for three months or longer. If you're using the 5% Deposit Scheme, your entire deposit needs to meet genuine savings criteria or fall within acceptable gift or guarantee arrangements. Air Force members posted overseas may accumulate savings in foreign currency, which most lenders accept once converted and held in an Australian account for the required period.

What happens between contract exchange and settlement

After you sign the contract, the developer builds the property while you continue with your current living arrangements. You're not required to make mortgage repayments during construction because the loan doesn't activate until settlement. Your deposit sits in a trust account or is released to the developer according to the contract terms.

During construction, your lender may request updated financial documents closer to settlement. If you've changed postings, updated your income, or taken on new debt, you'll need to provide fresh payslips, tax returns, and bank statements. Lenders reassess your borrowing capacity based on current circumstances, not those at contract exchange.

The developer notifies you when the property reaches practical completion, usually 14 to 21 days before the scheduled settlement date. You arrange a pre-settlement inspection to identify defects or incomplete work. Any issues should be documented and raised with the developer before settlement. Once the property settles, you take ownership and the mortgage activates. Repayments begin from that point.

In our experience, Air Force members often prefer to time settlement with a posting cycle. If you sign a contract while at Williamtown and expect to post to Edinburgh in 18 months, the settlement timeline may align with your move. If posting timelines shift, you can rent the property out after settlement or occupy it remotely until you relocate. Either approach works as long as you meet your lender's requirements and any owner-occupier conditions attached to grants or concessions.

Fixed or variable rate decisions for off-the-plan loans

You choose between a fixed interest rate and a variable interest rate closer to settlement, not at contract exchange. Locking in a fixed rate too early means you could miss out if rates fall during construction. Waiting until just before settlement lets you assess current market conditions.

Fixed rates provide certainty over your repayment amount for a set period, typically one to five years. Variable rates fluctuate with the market and usually offer features like offset accounts and redraw facilities. Some lenders let you split your loan between fixed and variable portions, giving you partial rate protection while retaining flexibility.

If you're using the 5% Deposit Scheme, confirm that your chosen lender offers both rate types under the scheme. Not all participating lenders provide the same product features. Some restrict offset accounts on low deposit loans, while others allow full access to variable rate features. Ask your broker which lenders offer the specific features you need before applying for pre-approval.

Valuation risks and sunset clauses

Lenders order a property valuation at or near settlement to confirm the property's market value matches the contract price. If the valuation comes in below the contract price, your lender may reduce the loan amount, leaving you to cover the shortfall with additional cash or by renegotiating with the developer.

Valuation shortfalls occur when the market softens during construction or when the contract price was set above market value. Off-the-plan buyers face this risk more than established property buyers because of the time gap between contract and settlement. If you're using the 5% Deposit Scheme and the valuation drops, you may need to increase your deposit to meet the 5% threshold based on the new valuation, not the contract price.

Sunset clauses allow either party to withdraw from the contract if settlement doesn't occur by a specified date. Developers use sunset clauses to exit contracts if construction delays push settlement beyond the clause date. If the developer cancels under a sunset clause, you receive your deposit back, but you lose the opportunity to purchase at the agreed price. In a rising market, this can be costly. In a falling market, it may work in your favour. Sunset clauses typically range from 24 to 36 months from contract exchange.
