The Structure That Separates Site Acquisition From Development Finance
Purchasing a multi-unit development site typically requires two distinct loan facilities: one to acquire the land, and another to fund construction once council approval and pre-sales are secured. The acquisition loan sits as land finance against the site's current value, while the construction facility references the end value of completed units. Some lenders will roll both into a single approval with staged drawdown, but most treat them as separate assessments with different serviceability tests and security positions.
Consider a buyer acquiring a 1,200-square-metre site in Footscray zoned for six townhouses. The land purchase might be financed at 65% loan-to-value ratio as a standard commercial loan, with full principal and interest repayments from day one. Once they secure a planning permit and engage a registered builder under a fixed price building contract, they apply for the construction facility, which may lend up to 70% of the completed project value depending on pre-sales and the buyer's capacity to service both loans during construction.
The timing gap between these two stages often determines whether the deal works. If council approval drags out or the development application requires amendments, you are servicing land debt without drawing construction funds. That serviceability drain has ended more than one development before a slab gets poured.
Equity Depth and the Pre-Sale Threshold Lenders Actually Enforce
Most construction lenders funding multi-unit sites will require at least 30% to 35% genuine equity and a minimum of two pre-sold units before releasing the first construction drawdown. Equity includes cash, unencumbered property, or a combination, but not projected profit from the development itself. The pre-sale requirement protects the lender's position if the market softens mid-build, but it also creates a timing bind: you need enough finished marketing material to sell off the plan, but you cannot start construction without pre-sales.
Lenders assess serviceability on the full loan amount during construction, even though you are only drawing progressively. They assume you will be paying interest on the land loan plus interest on drawn construction funds, and they want proof you can cover both without relying on unit sales. If you are an owner-occupier intending to live in one unit, some lenders will factor in imputed rent, but if this is a pure investment play, they will stress-test your existing income and assets against worst-case drawdown scenarios.
The equity conversation also determines whether you need a guarantor or cross-collateralised security. A buyer with $400,000 in unencumbered equity and strong serviceability might fund a $1.2 million site and construction package without additional security. A buyer stretching to 70% loan-to-value ratio will almost certainly need to pledge another property or bring in a financial guarantor.
How Progressive Drawdown Aligns With Your Builder's Payment Schedule
Construction finance is released in stages tied to completed milestones, not calendar dates. The builder submits a progress claim once a stage is finished, the lender arranges an independent inspection, and the funds are drawn down directly to the builder or released to you for payment. You only pay interest on the amount drawn, which keeps holding costs lower than a fully drawn term loan, but it also means your cash flow is constantly shifting as each stage completes.
A typical progress payment schedule for a multi-unit site might include a deposit on contract signing, then drawdowns at slab down, frame up, lock-up, fixing stage, and practical completion. Each stage represents roughly 15% to 20% of the total contract price, though the deposit is usually 10%. The lender will charge a progressive drawing fee each time funds are released, often between $300 and $500 per drawdown, and some lenders cap the number of draws included before additional fees apply.
If your builder operates on a cost-plus contract rather than a fixed price building contract, fewer lenders will touch the deal. Cost-plus structures leave the final build cost undefined, which creates risk the lender cannot model. Fixed price contracts are the standard for multi-unit construction funding, and any variation clause that lets the builder increase the price beyond 5% without your written consent will trigger a decline from most credit teams.
Council Approval Timing and the Risk of Conditional Finance Expiring
Most lenders issuing formal approval for construction loans will include a condition requiring you to commence building within a set period from the disclosure date, often six to twelve months. If your development application is still with council or under appeal at the Victorian Civil and Administrative Tribunal, that clock is running whether you are ready to build or not. Conditional approvals can sometimes be extended, but extensions are not automatic and usually require a full serviceability reassessment.
In growth corridors like Clyde North or Cranbourne, where council workloads are heavy and planning objections are common, a six-month approval window can expire before you even receive a planning permit. That risk is why experienced buyers will lodge the development application before they exchange contracts, using a subject-to-planning clause to protect the deposit. The clause gives you an exit if the permit is refused or comes back with conditions that make the project unviable, and it keeps the finance timeline aligned with the build start date.
If you do commence building within the lender's required period, the construction facility converts to active drawdown and the land loan may be consolidated into the construction facility depending on the lender's structure. If you miss the window, you are back to square one with a new application, updated valuations, and no certainty the same rate or loan amount will still be available.
Serviceability During Construction and Why Lenders Stress-Test the Worst Month
Lenders do not assess your capacity to service a construction loan based on average monthly costs. They model the month where you are paying interest on the land loan, interest on 80% of the construction drawdown, holding costs on unsold units, and your existing mortgage or rent. That month might only last thirty days in reality, but if you cannot service it on paper, the loan will not be approved.
This is where interest-only repayment options during construction become critical. Most lenders offer interest-only terms on both the land and construction facilities until practical completion, at which point the loan converts to principal and interest or is repaid from unit sales. The interest-only structure keeps monthly outlays lower, but the serviceability test still assumes you can cover peak debt before any units settle.
If your income is largely commission-based, self-employed, or structured through a trust or company, the serviceability hurdle gets higher. Lenders will typically discount variable income by 20% and require two years of financials showing consistent profit. If you are using rental income from another investment property to support serviceability, they will shade that income by 20% to 30% depending on the lender's policy. The math has to work under stress, or the credit team will decline regardless of how strong the deal looks on the surface.
When a Development Feasibility Study Becomes a Lending Requirement
Some lenders will require a formal feasibility study or quantity surveyor's report before approving construction finance for a multi-unit site, particularly if the project exceeds four dwellings or the loan amount is above $2 million. The study breaks down expected costs for site works, construction, professional fees, council contributions, and holding costs, then compares that total against projected sale prices to determine whether the project is viable. If the feasibility shows a profit margin below 15% to 20%, most lenders will either decline or reduce the loan-to-value ratio.
You can commission the study yourself through a quantity surveyor or development consultant, and the cost is usually between $2,500 and $5,000 depending on project size. The report also serves as a reality check before you commit. If the numbers are marginal on paper, they are usually worse in reality once cost overruns, timing delays, and selling costs are factored in.
Lenders treat the feasibility study as a third-party validation of your assumptions. Even if you have built before, even if you have run your own numbers, they want an independent view on whether the project stacks up. If you cannot fund the deposit and feasibility study from your own resources, that is often a signal the deal is undercapitalised from the start.
The Exit Strategy Lenders Assess Before Approving the First Drawdown
Every construction lender wants to know how they are getting repaid. For a multi-unit development site, the exit is usually staged sales as each townhouse or apartment reaches practical completion and settles with the end buyer. The lender will model that exit based on your pre-sales, the current market absorption rate for similar stock in the area, and whether you have sold the units through an agent with a marketing campaign or off-plan during construction.
If your exit relies on selling all units within three months of completion in a suburb where similar projects are taking nine months to sell out, the lender will either decline or hold a higher contingency reserve. Some lenders will require you to hold back a portion of the construction facility until at least 70% of units have settled, which means you may need to fund the final stage of construction from your own capital or a mezzanine facility.
The weakest exit strategy is refinancing into a standard investment loan and holding all units as rentals. That strategy assumes you can service the full debt on rental income alone, which is rarely possible without significant additional equity or income. Lenders will assess that exit, but they will not approve construction funding on that basis unless your serviceability is exceptionally strong and you are willing to hold at least 40% equity in the completed project.
Frequently Asked Questions
How much deposit do I need to finance a multi-unit development site in Victoria?
Most lenders require at least 30% to 35% genuine equity to finance both land acquisition and construction of a multi-unit site. This equity can include cash or unencumbered property, and does not include the projected profit from the development.
Do I need pre-sales before construction finance is approved?
Yes, most construction lenders require a minimum of two pre-sold units before releasing the first construction drawdown for multi-unit sites. This protects the lender if the market softens and ensures there is confirmed buyer demand.
What happens if my council approval is delayed and my finance approval expires?
If you do not commence building within the lender's required period, usually six to twelve months from disclosure, your conditional approval may expire. You would need to reapply with updated valuations and serviceability checks, with no guarantee the same rate or loan amount will be available.
Can I use a cost-plus building contract for multi-unit construction finance?
Most lenders will not approve construction finance for multi-unit sites with cost-plus contracts because the final build cost is undefined. Fixed price building contracts are the standard requirement for development funding.
How do lenders assess my ability to service a construction loan during the build?
Lenders stress-test your serviceability based on the worst month during construction, when you are paying interest on the land loan, up to 80% of construction drawdown, and any existing debts. The loan must be serviceable under that peak scenario, even if it only lasts thirty days.
