The journey from 'I want a home loan' to 'my home loan is approved and I can settle' involves two distinct formal stages: conditional approval (pre-approval) and formal approval (unconditional approval). Both are significant milestones, but only formal approval is a firm commitment from the lender to fund your purchase. Understanding what separates these two stages — and what can derail the process between them — is essential knowledge for any Australian home buyer.
What Conditional (Pre-) Approval Means and What It Confirms
Conditional approval — also called pre-approval, indicative approval, or approval in principle — is issued by the lender after reviewing your financial information and determining that you meet their lending criteria. It confirms that, subject to finding a suitable property and your financial circumstances not changing, the lender is willing to lend you up to a specified maximum amount.
Conditional approval is based solely on your financial profile — the lender has not yet seen the specific property you want to buy. This means the approval is conditional on: the property being acceptable as security (value, construction type, location); the property valuation supporting the purchase price; and your financial circumstances remaining materially unchanged. Conditional approval is valid for three to six months with most lenders.
Conditional Approval at Auction
If you intend to bid at auction, conditional approval is essential preparation — but understand its limits. At auction, contracts are unconditional and there is no cooling-off period. Your bid must be made with confidence that formal approval will follow. The risk at auction is a post-auction valuation shortfall — the lender's valuation may come in below the hammer price, requiring you to cover the gap in cash.
What Formal (Unconditional) Approval Means and When It Occurs
Formal approval — also called unconditional approval or full loan approval — is issued after you have a signed contract of sale for a specific property. The lender will: conduct a formal credit reassessment to confirm your financial circumstances are unchanged; commission a valuation of the specific property you have contracted to purchase; review the contract of sale terms; and confirm that the property meets their security requirements.
Once all conditions are satisfied and the lender issues formal approval, it issues loan documents for you to sign and return. The loan is then ready to fund at settlement. The process from signed contract to formal approval typically takes two to four weeks, depending on lender processing times, valuation turnaround, and how quickly you return signed documents.
What Can Go Wrong Between Conditional and Formal Approval
Several events can derail a formally approved loan between the conditional and formal stages. Valuation shortfall is the most common: if the lender's valuation of the property comes in below the purchase price, you need either additional cash (to cover the gap) or to renegotiate the purchase price. A $750,000 contract with a $720,000 valuation creates a $30,000 shortfall that must be funded — the lender will not lend more than 80% (or the approved LVR) of $720,000.
Financial changes in the applicant between conditional and formal approval are another risk: job changes, taking out new credit, increased credit card balances, or a change in relationship status can all trigger a reassessment. The lender does not actively monitor your finances between the two stages — but it will re-verify your employment and credit file before issuing formal approval.
Do Not Change Jobs or Take On New Debt Between Approval Stages
The period between receiving conditional approval and reaching formal approval is not the time for financial changes. Do not: change employers, take out any new credit product, increase credit card limits, make large purchases on credit, or reduce working hours. Any of these can change the lender's assessment and delay or prevent formal approval.
