Off-the-plan purchases require approval twice: once at contract signing and again at settlement, which may occur 18 to 36 months later.
Tradies buying off-the-plan often underestimate how a change in employment status between contract and completion can affect final approval. If you move from wages to a contracting arrangement or start your own business during construction, lenders treat your income differently at settlement. This creates approval risk even when your actual earnings increase.
Purchase Structure and Deposit Requirements
Most off-the-plan contracts require a 10% deposit paid in stages: typically 5% at exchange and the remaining 5% within 90 days. Lenders assess your borrowing capacity based on the full purchase price, not the deposit amount. Your home loan pre-approval covers the loan amount you'll need at settlement, but it doesn't lock in that approval for the duration of construction.
Consider a carpenter purchasing a two-bedroom apartment in a development scheduled for completion in 24 months. At contract signing, he's employed full-time with two years of continuous PAYG income. His lender provides conditional approval based on that employment structure. Eighteen months later, he transitions to subcontracting with higher daily rates but variable weekly hours. At settlement, the lender requires two years of ABN trading history or 12 months of tax returns showing consistent self-employed income. Without that documentation, the original approval doesn't convert to settlement funding.
The deposit funds must be genuine savings or gifted funds, with a clear paper trail showing accumulation over at least three months. Lenders scrutinise deposit sources more closely on off-the-plan purchases because the extended timeline creates more opportunity for financial circumstances to shift.
How Lenders Assess Off-the-Plan Applications
Lenders apply a loan-to-value ratio to the lower of purchase price or market valuation at settlement. If the development completes into a softer market, or if comparable sales in the building underperform projections, your approved loan amount may reduce. A purchase price of $650,000 with 10% deposit requires a 90% LVR loan. If the valuation at settlement comes in at $620,000, the lender recalculates based on that figure. You'll need to cover the $30,000 shortfall plus Lenders Mortgage Insurance on the higher LVR.
Some lenders cap off-the-plan lending at 80% LVR regardless of your deposit size. Others apply postcodes restrictions or limit exposure to specific developments. Your broker should confirm the lender's appetite for the development and unit type before you exchange contracts, not after the deposit clears.

Sunset Clauses and Construction Delays
Most contracts include a sunset clause allowing either party to terminate if construction doesn't complete by a specified date. Developers occasionally use this clause to cancel contracts in rising markets, returning your deposit but leaving you without the property. If this occurs after your financial circumstances have changed, you may not secure equivalent financing for an alternative purchase.
Construction delays extend the period between approval and settlement. A home loan pre-approval typically remains valid for 90 days, though some lenders extend this to six months. When construction runs 12 months over schedule, you'll need to reapply. Interest rate movements during that period can reduce your borrowing capacity if rates increase, or leave you without access to lower rates if they fall and you've locked in a fixed rate product early.
Delay clauses in off-the-plan contracts rarely compensate buyers for financing changes caused by extended construction periods. Your contract price remains fixed, but your borrowing capacity and the property's market value do not.
Income Documentation for Settlement Approval
Lenders require current income verification at settlement, regardless of what was provided at pre-approval. For PAYG tradies, this means recent payslips covering 30 to 90 days and an employment letter confirming ongoing status. For self-employed buyers, lenders typically require the most recent tax return, business activity statements, and bank statements showing trading income.
If you're self-employed for fewer than 12 months at settlement, most lenders decline the application or require a guarantor. Full-doc lenders need two years of financials. Low-doc products exist but carry higher interest rates and often cap at 80% LVR, which doesn't suit most off-the-plan purchases requiring 90% lending.
Timing your transition to self-employment around an off-the-plan settlement creates financing risk. If you're planning to start a business or move to contracting, structure that change to occur after settlement or delay your off-the-plan purchase until you have the required trading history.
Interest Rate Options and Lock-In Periods
You can't lock in a fixed interest rate at contract signing for settlement 24 months away. Fixed rate terms begin when the loan settles and funds disburse. Some lenders allow you to lock a rate 90 days before settlement, but this requires certainty around the completion date.
A split loan structure allows you to fix a portion of the loan and keep the remainder on a variable rate. This limits exposure to rate increases while maintaining access to an offset account on the variable portion, which most fixed rate products don't permit. For tradies with variable income, an offset account linked to the variable portion reduces interest on surplus cash without locking funds into the loan.
Variable rate products offer portability and flexibility if you need to sell before settlement or shortly after. Fixed rate loans often carry break costs if you discharge early, which becomes relevant if construction delays force you to reconsider the purchase or if work takes you to a different location.
Development Risk and Lender Appetite
Lenders assess developments individually. A project with 200 apartments and 60% presales may attract full lending support from major banks. A smaller development with 30 units and 40% presales might only secure funding from second-tier lenders at higher rates or reduced LVRs.
If the developer's financial position deteriorates during construction, lenders may withdraw appetite for that project entirely. This doesn't void your contract, but it forces you to find alternative funding, often at less favourable terms. Some buyers assume construction loans apply to off-the-plan purchases. They don't. Construction loans fund progressive building payments for owner-builders or custom homes. Off-the-plan purchases require a standard owner-occupied home loan or investment loan that settles in a single drawdown at completion.
Valuation Risk at Settlement
The settlement valuation determines your final loan amount. Lenders order a valuation four to six weeks before settlement. If the valuer assesses the property below purchase price, you'll need additional funds to cover the gap. This occurs when comparable sales in the building settle lower than projected, or when the broader market softens during construction.
A plumber purchasing a townhouse for $720,000 with a 10% deposit and 90% LVR loan expects to borrow $648,000. The development completes into a market where recent sales in the same complex settle between $680,000 and $700,000. The valuation comes in at $690,000. His maximum loan at 90% LVR is now $621,000. He needs an additional $27,000 at settlement, plus the LMI recalculation on the higher effective LVR, or he risks contract breach and deposit forfeiture.
Some lenders offer deposit bonds as an alternative to cash deposits, but these still require the same income and credit assessment and don't reduce valuation risk.
An off-the-plan purchase commits you to a price today for a property you'll own in two years. Your income, the lender's policies, interest rates, and the property's value will all move during that period. Manage each variable separately rather than assuming the approval you receive at contract signing will carry through unchanged to settlement.

Frequently Asked Questions
Can I lock in a home loan interest rate when I sign an off-the-plan contract?
You cannot lock in a fixed interest rate at contract signing for settlement 24 months away. Fixed rate terms begin when the loan settles and funds disburse. Some lenders allow you to lock a rate 90 days before settlement, but this requires certainty around the completion date.
What happens if I change from PAYG to self-employed before settlement?
Lenders require current income verification at settlement. If you become self-employed during construction, most lenders need 12 months of tax returns or two years of financials. Without that documentation, your original approval may not convert to settlement funding, even if your income increased.
What is valuation risk in off-the-plan purchases?
Valuation risk occurs when the property's assessed value at settlement is lower than your purchase price. Lenders calculate your loan amount based on the lower figure, meaning you'll need additional funds to cover the gap or risk breaching the contract and losing your deposit.
How long does off-the-plan home loan pre-approval last?
Pre-approval typically remains valid for 90 days, though some lenders extend this to six months. When construction delays push settlement beyond that period, you'll need to reapply, and your borrowing capacity may change based on updated interest rates, income, or lender policies.
Do I need Lenders Mortgage Insurance on an off-the-plan purchase?
You'll need LMI if your loan-to-value ratio exceeds 80%. Most off-the-plan purchases with a 10% deposit require 90% LVR lending, which triggers LMI. If the valuation at settlement comes in below purchase price, your effective LVR increases and so does the LMI premium.
