Top 10 Ways to Finance a Multi-Unit Development Site

How Construction Finance Works for Development Sites

Construction finance for a multi-unit development site splits your borrowing into two stages: purchasing the land, then funding the build as work progresses. You'll need a land loan to settle the purchase, followed by a construction facility that releases funds according to a progress payment schedule tied to build stages.

Consider an electrician purchasing a development site zoned for three townhouses. The land costs $600,000, and the build contract for all three units totals $900,000. The lender approves a $1.5 million facility: $600,000 releases at settlement to buy the land, then the remaining $900,000 draws down in stages as the builder completes the slab, frame, lockup, fixing, and practical completion for each dwelling. You only pay interest on funds actually drawn, which means during the first few months when only the land portion is drawn, your repayments stay lower than if the full amount were released upfront.

Most lenders structure this as a construction to permanent loan, converting to a standard home loan once the project completes. During construction, you typically make interest-only repayments on whatever portion of the loan has been drawn down. Once you've finished building and obtained occupancy certificates, the loan switches to principal and interest unless you've arranged to keep it interest-only, which some electricians do if they're holding the units as investments.

Deposit Requirements and Pre-Approval Strength

Lenders typically want 20% to 30% deposit for a multi-unit development site, calculated on the total facility including both land and construction costs. That puts the deposit requirement between $300,000 and $450,000 on a $1.5 million project. Some lenders assess risk differently depending on whether you're an owner-builder or using a registered builder with a fixed price building contract, with the latter generally requiring a lower deposit.

Pre-approval matters more for development sites than standard house purchases because you're often competing against other buyers at auction or negotiating off-market. Having finance locked in before you make an offer gives you certainty on what you can actually fund. When applying for pre-approval, lenders assess your borrowing capacity based on both your current income and the completed project. If you plan to sell the units on completion, they'll look at presale contracts or comparable sales. If you're keeping them as rentals, they'll assess projected rental income once the builds finish. For electricians running their own business, having two years of tax returns and current financials ready speeds up the self-employed loans assessment process.

Progressive Drawdown and Payment Schedules

The construction draw schedule determines when funds release from your loan facility to pay the builder. Most lenders use a five-stage or six-stage schedule: base stage (slab complete), frame stage, lockup stage, fixing stage, practical completion, and sometimes a final stage after defect rectification. Each stage represents roughly 15% to 25% of the total build cost.

Your lender arranges a progress inspection before releasing funds for each stage. An independent building inspector or valuer attends the site, confirms the work matches what the builder claimed, then authorises the drawdown. The lender charges a progressive drawing fee for each inspection, usually between $300 and $500 per visit. On a multi-unit build with three dwellings, you might have inspections scheduled for each dwelling separately, or grouped if they're progressing at the same pace, which affects the total number of inspection fees you'll pay across the project.

Some builders prefer progress payments based on their own schedule rather than the lender's standard stages. A cost plus contract might require payments for materials and labour as they occur, while a fixed price contract locks in stage payments upfront. Lenders generally prefer fixed price contracts with registered builders because the cost certainty reduces their risk, which can translate to better interest rates or lower deposit requirements for you.

Council Approval and DA Timing

Your lender won't release construction funds until you've got council approval and all conditions satisfied. That includes the development application approval, construction certificate, and any conditions like bonding for road or drainage work. Most construction loan approvals require you to commence building within a set period from the disclosure date, usually six to twelve months. If your DA takes longer than expected or gets knocked back, you're holding land with a loan accruing interest but no ability to draw construction funds.

In our experience with electricians buying development sites, the DA process often takes longer than anticipated. Submitting plans that comply with local planning controls upfront avoids the back-and-forth that stretches approval times. Some electricians use their trade connections to get the electrical, plumbing, and structural details right first time, which keeps consultants and council moving. Once you've got DA approval, the clock starts on your construction commencement deadline, so having your builder and any owner-builder arrangements confirmed before settlement keeps the project moving.

Interest Rates and Cost Structure During the Build

Construction loan interest rates typically sit 0.3% to 0.7% higher than standard variable home loan rates. Lenders price the additional risk of funding a project that doesn't yet exist. During construction, you're charged interest only on the amount drawn down, which rises as each progress payment releases. Once the build completes and the loan converts to a standard home loan, the rate usually drops to match the lender's residential investment loan rates if you're keeping the units as rentals.

In a scenario like this: you settle the land in January with $600,000 drawn. Your first progress payment of $150,000 releases in March after the base stage inspection. By March, you're paying interest on $750,000. Another $180,000 releases in May for the frame stage, taking your drawn balance to $930,000. Interest compounds monthly on the rising balance, but because you're only paying interest without principal reductions, monthly repayments stay manageable during construction. Once all three units reach practical completion and you've leased them out, the loan converts and you can switch to principal and interest repayments or keep it interest-only depending on your tax and cash flow strategy. Electricians holding the units as investments often choose interest-only repayment options to maximise deductible interest and free up cash for the next project.

Owner Builder vs Registered Builder Implications

Using a registered builder with a fixed price building contract gives you access to more lenders and typically lower deposit requirements. Most mainstream banks will lend for construction projects using registered builders, but limit owner-builder finance to specialist lenders or require larger deposits and higher rates. If you're an electrician planning to project-manage the build and pay sub-contractors directly, expect to put down 30% deposit and prove you've got builder's insurance and the required owner-builder permits.

Owner-builder projects also face stricter progress inspection requirements. The lender wants detailed cost breakdowns for each trade and receipts showing payment to sub-contractors before releasing the next stage of funds. Instead of five broad stages, you might need to provide evidence for ten or twelve smaller milestones. That creates more inspection fees and admin work, but gives you control over how trades are scheduled and paid. For electricians with strong trade networks and the time to manage a multi-unit build, the cost saving from handling it yourself can outweigh the additional lending hurdles, particularly if you're completing the electrical work in-house and reducing that line item from the build cost.

Exit Strategy and End-Use Assessment

Lenders assess your development site loan based on what happens after construction completes. If you're selling the units on completion, they'll want evidence the project stacks up financially. That means a valuation showing the completed units will be worth more than your total borrowing, plus presale contracts if the lender requires them to reduce their risk. If you're keeping the units as rentals, the lender assesses projected rental income and runs a serviceability test to confirm you can afford the loan once it converts to principal and interest repayments.

For electricians planning to retain the development as part of their investment property portfolio, rental income from all three units might cover the loan repayments and generate positive cash flow, particularly if you've kept build costs down by doing some work yourself. The lender uses a rental assessment at 70% to 80% of market rent when calculating serviceability, so even if you achieve full market rent, they'll assess you on a discounted figure to allow for vacancies and management costs. That affects how much you can borrow and whether you'll need to contribute additional income from your electrical business to service the debt.

Structuring for Tax and Cash Flow

How you structure the loan affects your tax deductions and cash flow during and after construction. Interest on the construction loan is generally deductible if you're building to sell or building investment properties, but speak to your accountant about timing. Interest during construction can sometimes be capitalised and added to the cost base of each unit rather than claimed as a deduction in the year it's incurred, which affects your capital gains tax when you eventually sell.

If you're planning to live in one unit and rent the other two, the loan needs to be split so interest on the investment portion stays deductible while the owner-occupied portion doesn't attract a tax benefit. Most lenders can split a construction facility into separate loan accounts once construction completes, with each account linked to a specific unit. That way your accountant can clearly identify deductible and non-deductible interest at tax time. Electricians sometimes refinance once the project completes to access cheaper rates or pull out equity for the next development, but structuring it correctly from the start avoids complications later.

Application Requirements and Documentation

Applying for construction finance on a development site involves more paperwork than a standard home loan for electricians. You'll need council plans, a copy of the development application approval, the building contract, a detailed cost breakdown, and a valuation of the completed project. If you're using a builder, include their license details and proof of builder's warranty insurance. If you're going the owner-builder route, include your owner-builder permit and insurance certificates.

Lenders also assess your personal financial position: recent payslips if you're employed, tax returns and financials if you're self-employed, current loan statements, asset and liability details, and proof of your deposit funds. Because construction lending involves more risk than standard home loans, lenders scrutinise your income stability and existing debts closely. Electricians with fluctuating income from contract work should provide a longer income history or show consistent turnover across multiple years to satisfy the lender's serviceability assessment. Having your accountant prepare a current profit and loss statement and balance sheet before you apply speeds up the process and reduces the chance of the lender requesting additional information mid-assessment.
