Construction loan approval works differently to standard home finance. Lenders assess both your ability to service the debt and the viability of the project itself, which means you need council approval, a fixed price building contract, and detailed costings before most lenders will proceed. The application timing matters because most construction loan approvals require you to commence building within a set period from the disclosure date, typically three to six months.
What Lenders Assess During Construction Loan Approval
Lenders evaluate three distinct components: your financial position, the builder's credentials, and the project feasibility. You'll need to demonstrate serviceability based on the full loan amount, even though you'll only be charged interest on the amount drawn down during construction. The builder must hold current registration and appropriate insurance. The project itself needs council approval and a fixed price building contract that clearly defines the progress payment schedule.
Consider a buyer in Preston who secured a site near the northern end of Plenty Road. The land purchase settled without issue, but the construction loan application stalled for six weeks because the initial building quote didn't itemise demolition costs separately from the main contract. The lender required a revised contract showing demolition as a distinct line item before proceeding. Once resubmitted with the correct structure, approval took eight business days.
Council Approval and Development Applications
Your development application must receive formal council approval before a construction lender will issue unconditional approval. Some lenders will provide conditional approval while the council application is pending, but they won't release funds until you provide stamped, approved plans. Darebin Council, which covers Preston, typically processes standard residential applications within 60 statutory days, though complex designs or heritage overlays can extend this timeframe.
The approved plans form part of the loan security. Lenders cross-reference the council plans against the building contract to confirm the scope matches what you're financing. Any variation between the two documents will trigger queries and potential delays.
Fixed Price Contracts and Cost Plus Arrangements
Most banks and mainstream lenders require fixed price building contracts for construction loan approval. The contract sets out the total build cost and defines when progress payments fall due. This structure protects both you and the lender from cost blowouts during construction. The progress payment schedule typically aligns with stages such as base, frame, lock-up, fixing, and practical completion.
Cost plus contracts, where you pay for materials and labour as incurred, are harder to finance through traditional lenders. Owner builder finance also sits outside standard construction loan products. If your project falls into either category, you'll need a specialist lender who structures funding around progressive drawdown based on actual costs rather than predetermined milestones.
The Progressive Drawdown Process
Construction funding releases in stages as the build progresses. You don't receive the full loan amount upfront. Instead, the lender inspects the site at each milestone and releases the corresponding payment once satisfied the work is complete. Between drawdowns, you only pay interest on the amount already advanced, not the total approved sum.
Most lenders charge a progressive drawing fee each time funds are released, typically ranging from $200 to $400 per inspection. These fees apply throughout the build, so a five-stage construction will incur five separate charges. Some lenders cap the total fees or offer a fixed package price, which can reduce costs on longer builds.
Interest-Only Repayments During Construction
Construction loans typically operate on interest-only repayment options during the building period. You pay interest monthly on whatever portion of the loan has been drawn down, but principal repayments don't commence until the build completes and the loan converts to a standard mortgage. This structure keeps your payments manageable while you're potentially paying rent or another mortgage elsewhere.
The interest rate during construction may differ from the rate that applies once the loan converts to a construction to permanent loan. Some lenders use a variable rate throughout, while others allow you to fix the rate either at approval or at conversion. The distinction affects your budgeting, particularly if the build extends beyond the expected timeframe.
How Land and Construction Packages Differ
A land and construction package finances both the site purchase and the build under a single approval. This structure works well for house and land packages where you're buying a titled lot and engaging a project home builder. The lender assesses the combined position and provides a single approval covering both components.
If you already own the land, you're applying for construction finance only. The existing equity in the site contributes to your deposit, and the lender values both the land and the proposed improvements when determining your loan-to-value ratio. Preston's established residential areas, particularly around Regent and Murray Road, often suit this approach because buyers purchase older homes on larger blocks with the intention to demolish and rebuild.
Timing Your Application to Avoid Lapses
Construction loan approvals expire if you don't commence building within the specified period from the disclosure date. This deadline exists because lenders base their approval on current property values, interest rates, and your financial position. If months pass without progress, those conditions may no longer hold.
In our experience, buyers who lock in council approval before applying for construction loans move through the process more efficiently than those who apply with pending permits. Conditional approvals provide some certainty, but they won't release funds or finalise terms until the council component resolves. If your build is contingent on selling another property or coordinating settlement timing, factor those dependencies into your application schedule.
Engaging Registered Builders and Tradespeople
Lenders require that all construction work is carried out by a registered builder holding appropriate licenses and insurance. The builder's credentials form part of the assessment. If the builder has a history of incomplete projects or insurance claims, lenders may decline the application outright or require additional documentation.
Progress inspections verify that work is complete before each payment releases. The inspector checks that the stage matches the contract description and that subcontractors such as plumbers and electricians have completed their work to code. Payment doesn't release until the inspection passes, which protects you from paying for incomplete work and gives the lender confidence that funds are being used appropriately.
When to Consider Renovation Finance Instead
If your project involves substantial alterations to an existing dwelling rather than a full rebuild, you may need a house renovation loan rather than new home construction finance. The distinction depends on whether the existing structure remains habitable during works and whether the scope involves extending or reconfiguring rather than demolishing and starting fresh.
Renovation finance often allows you to remain living in the property during works, whereas construction loans typically assume the site is vacant or will be cleared. The approval criteria overlap, but renovation products may accept more flexible contract arrangements and shorter build periods. For clients in Preston considering whether to renovate or rebuild, the decision often hinges on the condition of the existing structure and whether the block allows for the footprint you need. Blue Lion Lending can help assess which product fits your specific project.

Frequently Asked Questions
What documents do I need for construction loan approval?
You need council-approved plans, a fixed price building contract with a registered builder, detailed cost breakdowns, and proof of your financial position. Most lenders also require evidence of the builder's insurance and registration before issuing unconditional approval.
How long does construction loan approval take?
Once you submit a complete application with council approval and a signed building contract, most lenders take seven to fourteen business days to assess and issue approval. Incomplete applications or pending council permits will extend this timeframe.
Can I get construction loan approval before council approves my plans?
Some lenders offer conditional approval while your development application is with council, but they won't release funds or finalise terms until you provide stamped, approved plans. Unconditional approval requires completed council approval.
Do I pay interest on the full loan amount during construction?
No, you only pay interest on the amount drawn down at each stage. Construction loans release funds progressively as the build advances, and interest accrues only on the portion already paid to the builder.
What happens if my construction loan approval expires?
If you don't commence building within the set period from the disclosure date, usually three to six months, the approval lapses. You'll need to reapply, and the lender will reassess your financial position, the property value, and current interest rates before issuing a new approval.
