Buying a unit development site is a different transaction to purchasing an established property. The loan structure reflects that difference from the first conversation with a lender.
Development finance for site acquisition considers not just the land value but the entire project feasibility. Lenders assess the proposed development, your experience, and the exit strategy before committing funds. The deposit requirements, loan to value ratio, and documentation standards all sit outside the residential lending framework most buyers know.
Development Finance Starts With Land Acquisition
Land acquisition finance is the first phase of property development funding. You're borrowing against a site based on what it could become, not what it currently holds. A lender providing development finance will typically fund 60% to 70% of the site purchase price, depending on the strength of your development application and your capacity to service the loan amount during construction.
Consider a developer purchasing a site in Reservoir zoned for medium-density residential. The site comes with council approval for six townhouses. The lender will review the DA approval, construction quotes, presale commitments, and your business financials before settling on an LVR. That 65% funding offer means the developer needs 35% as a development deposit, plus holding costs until the first presale settles.
The land acquisition phase often involves a first mortgage secured against the site. If additional funding is required to cover project costs or fill a gap between the loan amount and total development costs, you might explore private lending or mezzanine finance as a second mortgage. Both carry higher development interest rates but provide access to capital when traditional lenders won't stretch further.
What Lenders Assess Beyond the Site Value
Lenders funding a unit development site want to see a complete picture of project feasibility before settlement. That includes construction costs, project timeline, anticipated end buyer demand, and your capacity to manage cost overruns. A variable interest rate loan gives flexibility if the development timeline extends beyond initial projections, while a fixed interest rate provides certainty during the build phase.
The loan application will require detailed project documentation: development approval from the local council, engineering reports, quantity surveyor costings, and a clear development exit strategy. If you're purchasing in an area like Coburg where demand for medium-density housing remains solid, that strengthens your case. If the site requires rezoning or a protracted council approval process, expect lenders to either decline or offer a lower LVR until DA approval is confirmed.
Your business financials matter as much as the project itself. Lenders assess your capacity to service interest during construction when there's no rental income and no sale proceeds. If you're holding other development projects or investment properties, those will factor into borrowing capacity calculations. A developer with strong cashflow from completed projects will access better development rates than someone financing their first build with limited reserves.

Development Equity and Presale Requirements
Development equity is the cash or unencumbered property you bring to the transaction. A lender offering 65% LVR expects you to contribute the remaining 35% from genuine savings, existing property equity, or a joint venture partner. That equity covers the development deposit and provides a buffer if project costs increase or the development timeline extends.
Presale finance is a common condition for unit developments. Lenders often require 50% to 70% of the completed units to be sold off the plan before they'll release construction funds. Those presale commitments prove end buyer demand and reduce the lender's exposure if the market softens during the build. A developer working on a site in Pascoe Vale might secure four presales from six proposed townhouses, satisfying the lender's requirement and unlocking staged funding as construction progresses.
JV finance introduces another equity source. A joint venture partner contributes capital in exchange for a share of the development profit. The lender treats that contribution as part of your development equity, improving the overall LVR and reducing the cash you need to inject upfront. The arrangement works when both parties bring something the other lacks: one partner has the site or development experience, the other provides funding or construction capacity.
How Development Costs Shape Loan Structure
Project costs extend well beyond the land price. A lender structures the development loan to cover acquisition, holding costs during DA approval, construction expenses, and interest capitalisation until the first sale settles. The loan amount reflects the total funding required to complete development and achieve a saleable outcome.
In our experience, developers underestimate holding costs during the council approval phase. A site purchased subject to DA approval might sit for six to twelve months while the application moves through the planning process. Interest accrues during that period, and if you've borrowed to acquire the site, those costs compound quickly. Structuring the loan to allow interest capitalisation during pre-construction avoids the need to service repayments from other income sources.
Cost overruns are a reality in most builds. A fixed-price building contract provides some protection, but variations, delays, and unforeseen site conditions still add expense. Lenders build a contingency buffer into the loan amount, typically 10% of construction costs, but that won't cover major scope changes or extended delays. Having access to additional funds through refinancing existing properties or accessing a secondary facility means you're not scrambling for capital halfway through the build.
Melbourne Development Sites and Council Dynamics
Melbourne's planning environment varies significantly by council area. Some municipalities actively encourage medium-density development, others impose restrictive overlays or lengthy approval processes. A site in Moonee Ponds with existing council approval for a four-unit development presents a lower-risk proposition than a similar site in Eltham requiring rezoning and multiple objector hearings.
Lenders familiar with development finance know which councils move applications efficiently and which introduce delays. That knowledge informs their assessment of project timeline and holding costs. A streamlined approval process in an area like Footscray, where the council supports urban consolidation, reduces the risk that your development timeline blows out and interest costs erode projected profit.
Local market conditions also influence how lenders view end buyer demand. A unit development site near Heidelberg's retail and transport precinct will attract stronger presale interest than a site in a less connected location. Lenders consider that demand when assessing whether your proposed development exit strategy is realistic.
Structuring Development Finance for Project Success
The structure of your development loan should align with the project cashflow. Staged drawdowns match funding releases to construction milestones, so you're not paying interest on the full loan amount from day one. Interest-only repayments during construction preserve cashflow, with principal repayment deferred until sales settle.
A development borrowing strategy that incorporates both acquisition and construction funding under one facility simplifies the process. You're dealing with a single lender, a single approval, and a clear path from site purchase through to project completion. Some lenders offer split facilities: one tranche for land acquisition at a lower development interest rate, another for construction at a higher rate reflecting the increased risk during the build phase.
Access to loan options from banks and lenders across Australia means you're not limited to a single institution's appetite or policy. Different lenders have different risk tolerances, different LVR caps, and different approaches to presale requirements. A broker working in development loans will match your project to the lender most likely to fund it on terms that support a profitable outcome.
Purchasing a unit development site is the beginning of a process that requires funding, planning, and execution over an extended timeline. The development finance structure you establish at acquisition shapes your capacity to realize your vision and fund the project through to completion.

Frequently Asked Questions
What loan to value ratio can I expect when purchasing a unit development site?
Lenders typically offer 60% to 70% LVR for land acquisition finance, depending on the strength of your development application, presale commitments, and business financials. You'll need to contribute the remaining 30% to 40% as development equity from cash, existing property, or a joint venture partner.
Do I need council approval before a lender will fund a development site purchase?
DA approval significantly strengthens your application and improves the LVR a lender will offer. Some lenders will fund acquisition before approval is granted, but they'll typically impose a lower LVR and require evidence that approval is likely based on zoning and planning overlays.
How do presale requirements affect development finance for unit sites?
Lenders often require 50% to 70% of units sold off the plan before releasing construction funds. Presale commitments demonstrate end buyer demand and reduce the lender's risk if market conditions change during the build.
What happens if development costs exceed the initial loan amount?
Most development loans include a 10% contingency buffer for cost overruns. If expenses exceed that buffer, you may need to inject additional equity, refinance existing properties, or arrange mezzanine finance to cover the shortfall.
Can I use equity from my home to fund a unit development site purchase?
Yes, equity from residential property can form part of your development deposit. The lender will assess your total borrowing capacity across all secured loans and ensure you can service both your home loan and the development loan during construction.
