Construction finance for an investment property charges interest only on the amount drawn down at each stage, not the full loan amount from day one.
That structure matters when building a rental property because construction takes months and your funds release in stages as the build progresses. If you're a Tasmanian government employee considering a land and build loan for an investment, understanding how progressive drawdown affects your holding costs changes how you budget for the project and how much rent you need to cover once the property settles.
How Construction Funding Differs from Standard Investment Loans
A standard investment loan releases the full amount at settlement. You pay interest on the total from that point forward. Construction finance releases funds progressively, typically across five or six stages: deposit, base stage, frame stage, lock-up stage, fixing stage, and completion. You only pay interest on what's been drawn.
Consider a buyer financing a build in Kingston. The land costs $280,000 and the building contract sits at $420,000. Total loan amount is $700,000. At the base stage, only $350,000 has been drawn. Interest applies to that amount, not the full $700,000. At current variable rates, that difference saves around $1,400 per month in interest during the early stages of the build.
Most lenders structure construction loans for public servants with interest-only repayment options during the building phase. Once the construction completes and the loan converts to a standard mortgage, you choose whether to continue interest-only or switch to principal and interest repayments depending on your investment strategy.
What a Progress Payment Schedule Looks Like in Practice
Your registered builder prepares a progress payment schedule before construction starts. That schedule lists each stage, the percentage of the building contract due at that stage, and the work that must be completed before the draw releases.
A typical progress payment schedule for a project home loan looks like this: 5% deposit on signing, 10% on base stage, 15% on frame stage, 35% on lock-up stage, 30% on fixing stage, and 5% on final completion. Lenders require a progress inspection before releasing each payment. The inspection confirms the stage is complete and the work meets building standards.
Lenders charge a Progressive Drawing Fee, usually between $150 and $400 per draw. Some charge per inspection, others charge a flat fee upfront. That fee covers the cost of sending a valuer or building inspector to verify the work. It's separate from the loan interest and comes out of each drawdown or gets added to your loan balance.

Why Council Approval Timing Affects Your Loan Start Date
Most construction loan applications require a development application lodged with council and a fixed price building contract signed with a registered builder. Some lenders approve the loan before council approval comes through, but the loan won't settle until you have council plans approved and a building permit issued.
In Hobart and Launceston, council approval times vary depending on the complexity of the build and the zone. A straightforward project home on suitable land in a residential zone might take six to eight weeks. A custom design in a heritage overlay or bushfire-prone area can take three to four months.
Lenders also include a condition that you commence building within a set period from the Disclosure Date, usually six to twelve months. If council delays push you past that window, you may need to reapply or get an extension. That timeline matters for Tasmanian government employees using investment loans for public servants who are juggling deposit timing and settlement on the land.
How Land and Construction Packages Change the Loan Structure
A land and construction package bundles the land purchase and building contract into one transaction. You settle on the land first, then construction begins. The loan releases in two parts: the land component at settlement, and the building component progressively as construction advances.
Some lenders let you capitalise the interest during construction, meaning the interest charges get added to your loan balance rather than paid monthly. That approach keeps your cash flow intact during the build but increases your total loan amount by the time the property completes. Other lenders require you to service the interest as it accrues.
If you're building an investment property while still renting or living elsewhere, capitalising interest during construction means you don't need to cover loan repayments and rent or your existing mortgage simultaneously. Once the build finishes and tenants move in, rental income starts covering the loan repayments.
What Happens if the Build Runs Over Budget
A fixed price building contract locks in the cost of construction, so the builder wears any cost overruns caused by materials or labour. You're protected from price increases during the build. But a cost plus contract passes those costs to you. Most lenders require a fixed price contract for construction finance because it protects both you and the lender from unexpected cost blowouts.
If you make variations during the build, those costs sit outside the fixed price contract. Adding a deck, upgrading appliances, or changing the floor plan mid-build creates additional payments outside the progress payment schedule. Lenders won't automatically fund variations. You either pay for them out of pocket or apply for a loan top-up before the variation is approved.
In our experience, buyers building investment properties keep variations minimal because every dollar added to the build cost increases the loan amount and reduces rental yield. The original contract price is usually the most accurate reflection of what the market will support when you come to lease the property.
How Construction Loans Convert Once the Build Completes
When construction finishes, the lender conducts a final inspection and releases the last progress payment to your builder. At that point, the loan converts from a construction loan to a standard mortgage. The loan amount is now fixed, and you move from paying interest on progressive draws to paying interest on the full loan balance.
Most construction to permanent loan products let you lock in your interest rate structure at the start of the build, so you know what rate applies once the loan converts. Some lenders let you fix part or all of the loan during construction, others keep you on a variable rate until conversion.
If you've been capitalising interest during the build, your loan balance at conversion will be higher than the original land and building contract total. That balance includes all the accrued interest from the construction phase. Once the property is tenanted and generating rental income, you can assess whether to continue with interest-only repayments or switch to principal and interest depending on your tax position and long-term investment goals.
Why Access to Multiple Lenders Matters for Investment Builds
Not all lenders offer construction finance for investment properties, and those that do apply different criteria. Some lenders won't fund owner builder finance or builds in regional Tasmania. Others cap the loan amount or require a larger deposit for investment construction compared to owner-occupied builds.
Being able to access construction loan options from banks and lenders across Australia means you're not limited to one lender's policy. One lender might cap investment construction at 80% of the land and building cost, requiring a 20% deposit. Another might lend up to 90% if you're a salaried government employee with a stable income history.
Tasmanian government employees often qualify for home loans for Tasmanian government employees with reduced fees or waived lender's mortgage insurance on owner-occupied purchases, but those benefits don't always extend to investment construction. Having a broker who understands which lenders treat public sector income favourably for investment builds saves time during the construction loan application process and often results in better loan terms.

Frequently Asked Questions
Do I pay interest on the full construction loan amount from day one?
No, lenders only charge interest on the amount drawn down at each stage of construction. If $350,000 has been released but your total loan is $700,000, you only pay interest on the $350,000 until the next progress payment.
Can I capitalise interest during the construction phase?
Some lenders let you capitalise interest, which means the interest charges get added to your loan balance rather than paid monthly. This keeps your cash flow intact during the build but increases your total loan amount by completion.
What happens if I want to make changes during the build?
Variations sit outside the fixed price contract and aren't automatically funded by your lender. You either pay for them separately or apply for a loan top-up before the variation is approved.
How long do I have to start construction once the loan is approved?
Most lenders require you to commence building within six to twelve months from the Disclosure Date. If council delays push you past that window, you may need to reapply or get an extension.
Do construction loans for investment properties have higher interest rates?
Investment construction loans may have slightly higher interest rates than owner-occupied construction loans, but the rate depends on your deposit size, lender, and whether you're using a variable or fixed rate structure.
