Beginner's Guide to Multi-Unit Development Site Loans

If you're looking at purchasing a multi-unit development site in Tasmania, the right construction loan structure matters more than the interest rate.

Buying land with the intention to build multiple dwellings is different from standard construction loans. The loan needs to cover not just the land purchase but also staged construction funding across multiple units, often over 12 to 24 months. You'll deal with progressive drawdowns, council approvals, and a progress payment schedule that releases funds as each stage is completed. For anyone working shifts, that means setting up a loan that doesn't require you to be on the phone to the bank every time a payment is due.

What Makes Multi-Unit Development Loans Different

Multi-unit development loans combine land purchase finance with construction funding for two or more dwellings on a single site. The lender assesses the project as a development rather than a standard owner-occupied build, which means different serviceability criteria and a more detailed application process.

You'll need council approval and a development application in place before most lenders will proceed. That approval confirms the site is zoned for multi-unit construction and that your design meets local planning requirements. The lender also wants to see a fixed price building contract with a registered builder, a detailed cost breakdown, and evidence that the project can be completed within the approved timeline.

Consider a scenario where you're looking at a dual-occupancy site in Glenorchy. You've found land zoned for two dwellings, secured council approval, and engaged a builder who's quoted a fixed price for both units. The land costs $280,000, and the construction cost is $620,000. Your lender structures the loan to release the land purchase amount at settlement, then disburses construction funds progressively as the builder completes foundation, frame, lock-up, fixing, and practical completion stages. You're only charged interest on the amount drawn down, so during the early months, your repayments sit lower than they will once both units are finished.

How Council Approval Affects Your Loan Application

You cannot proceed with a multi-unit development loan until you have development approval from your local council. Lenders treat this as a non-negotiable requirement because it confirms the land can legally support the number of dwellings you plan to build.

In Tasmania, councils assess multi-unit applications against the local planning scheme, which includes considerations like density, setbacks, parking, and stormwater management. The approval process can take several months, and you'll often need input from a town planner, architect, and surveyor before lodging the application. Once approved, the lender will review the council-stamped plans as part of your loan application. If the plans change after approval, or if you need to lodge an amended application, the lender may reassess the loan or delay drawdown until the updated approval is in place.

What Lenders Look for in a Development Application

Lenders assess your development application to confirm the project is viable, compliant, and likely to be completed on time. They'll review the council-approved plans, the site's zoning, and any conditions attached to the approval.

A strong application includes a fixed price building contract with a registered builder, a clear cost breakdown that covers all stages of construction, and evidence that you've allowed for contingencies. Lenders also want to see that the builder is appropriately licensed and insured, and that the contract includes a progress payment schedule aligned with standard construction milestones. If you're planning to act as an owner builder, expect fewer lenders to consider the application, and those who do will require additional documentation around your qualifications, trade experience, and ability to manage sub-contractors.

In our experience, applications run into trouble when the cost estimate is too tight or when there's no buffer for variations. A typical multi-unit project in Hobart or Launceston should include a contingency of around 5% to 10% of the total build cost to cover unforeseen site works, planning variations, or delays caused by weather or supply issues.

How the Progressive Drawdown Works

Construction funding is released in stages as the builder completes specific milestones. This is called a progressive drawdown, and it's how lenders manage risk on a development loan.

Most lenders work to a standard five-stage schedule: deposit or base stage, frame stage, lock-up stage, fixing stage, and practical completion. At each stage, the builder requests a payment, the lender arranges a progress inspection to confirm the work is complete, and then releases the funds directly to the builder. You'll be charged a Progressive Drawing Fee each time a drawdown occurs, typically between $200 and $400 per draw. Because you're only paying interest on the amount that's been drawn down, your repayments increase as the build progresses. During the first few months, you might only be paying interest on the land value. By lock-up, you're paying interest on the land plus around 60% to 70% of the construction cost.

Some lenders allow interest-only repayment options during the construction period, which keeps your cash flow manageable while you're still paying rent or a mortgage elsewhere. Once construction is complete, the loan typically converts to principal and interest repayments unless you're planning to hold the properties as investments.

Fixed Price Contracts vs Cost Plus

A fixed price building contract is the cleanest way to secure construction funding for a multi-unit site. The builder provides a single, locked-in price for the entire build, and the lender knows exactly how much the project will cost.

Under a cost plus contract, the builder charges you their costs plus a margin, which means the final price isn't confirmed until the build is finished. Most mainstream lenders won't touch cost plus contracts because there's too much uncertainty around the final loan amount. If you're using an owner builder arrangement or managing trades directly, you'll be working with a cost plus model by default, and you'll need a lender who specialises in that type of funding. Those lenders will ask for quotes from plumbers, electricians, and other sub-contractors before approving the loan, and they'll release funds progressively as each trade completes their work.

For anyone working shifts in Tasmania, a fixed price contract is the more practical option. You're not chasing quotes, managing variations, or trying to coordinate inspections around your roster.

What It Costs to Commence Construction

Most lenders require you to commence building within a set period from the loan settlement date, usually six to 12 months. If you don't start within that window, the lender may reassess the loan or require you to reapply.

Before construction starts, you'll need to pay for site preparation, soil tests, engineering reports, and council fees. These costs aren't always included in the builder's quote, and they can add up quickly. On a multi-unit site, expect to spend between $15,000 and $30,000 on pre-construction costs, depending on the site's condition and any remediation work required. If the land needs significant earthworks, retaining walls, or upgraded stormwater systems, those costs climb higher. Your lender may allow you to include some of these costs in the loan, but you'll typically need to cover at least part of them upfront.

Once construction begins, the lender releases the first drawdown to cover the builder's deposit or base stage payment. From that point, the progress payment schedule takes over, and funds are released as each milestone is signed off.

Serviceability for Multi-Unit Development Loans

Lenders assess your ability to service a multi-unit development loan based on your income, existing debts, and the projected rental income once the units are complete. If you're planning to live in one unit and rent the others, they'll include your salary plus the rental income from the tenanted dwellings.

For Tasmanian police officers, serviceability calculations often work in your favour because of stable income and strong job security. However, the lender will still apply a rental income discount, usually around 20%, to account for vacancies and maintenance costs. If you're building two units and planning to rent both, the lender will assess serviceability based on your salary alone during the construction period, then reassess once the units are completed and tenanted. That means you need enough income to service the full loan amount without relying on rental income until the build is finished.

If your income alone doesn't cover the loan, you might consider a guarantor loan, where a family member uses the equity in their home to support your application. This can be particularly useful if you're early in your career or carrying other debts that limit your borrowing capacity.

What Happens After Practical Completion

Once the builder reaches practical completion on all units, the lender conducts a final valuation and converts the loan from construction funding to a standard mortgage. At that point, you'll switch from interest-only repayments to principal and interest, unless you've arranged to keep the loan on an interest-only basis for investment purposes.

If you're planning to sell one or more of the units after completion, you'll need to notify the lender and arrange for the loan to be split or discharged as each property settles. Some lenders charge exit fees or break costs if you repay the loan early, particularly if you've locked in a fixed rate during the construction period. If you're keeping the properties as investments, you'll need to ensure your loan structure supports multiple titles and allows for future refinancing or equity release as the properties increase in value.
