Construction finance works differently to a standard home loan because you're not borrowing the full amount upfront.
The lender releases funds in stages as the build progresses, which means you're only paying interest on what's been drawn down at each point. That structure matters when you're working roster hours and need a loan that doesn't require constant oversight or midweek settlement meetings. Understanding how drawdowns, contracts, and payment schedules connect gives you control over the build without it controlling your time off.
How Progressive Drawdown Actually Works
Funds are released at specific stages of the build, not as a lump sum at settlement. The lender arranges an inspection at each stage, approves the completed work, then releases the next payment directly to your builder. You'll typically see five or six drawdowns across the build: base stage, frame stage, lock-up, fixing, practical completion, and final.
Consider a constable building in the Central Coast who's working a rotating roster. The base stage drawdown happens after the slab is poured and inspected. The lender releases around 15% of the total loan amount. Interest starts accruing only on that portion. By frame stage, another 20% is released. The borrower isn't managing the full loan amount from day one, and because inspections are arranged by the lender, there's no need to be on-site during business hours for each approval.
Most lenders charge a Progressive Drawing Fee for each inspection and drawdown, usually between $300 and $500 per stage. That's a cost to factor in, but it's also the mechanism that keeps your interest charges lower during construction. Between each stage, you're making interest-only repayments on the amount drawn so far, not the full loan. Once the build reaches practical completion, the loan converts to a standard construction to permanent loan with principal and interest repayments.

Fixed Price Contracts vs Cost Plus Contracts
A fixed price building contract locks in the build cost upfront. The builder agrees to complete the home for a set amount, and unless you make changes or the scope shifts, that price doesn't move. A cost plus contract charges you the actual cost of materials and labour, plus a builder's margin, which means the final cost isn't locked in until the build is finished.
Fixed price contracts suit most police borrowers because they give certainty. Lenders prefer them too, because the loan amount is clear from the start and the risk of cost blowouts sits with the builder, not the borrower. You'll need a registered builder and a signed contract before the lender will assess your construction loan application. The contract should include a progress payment schedule that aligns with the lender's drawdown stages.
Cost plus contracts can work if you're doing a custom design with materials that are hard to price upfront, but they're harder to fund. Lenders need a detailed estimate and will usually hold back a contingency buffer. If you're building a spec home or a project home from a volume builder, fixed price is the standard and the structure that gets you to approval faster.
Land and Construction Packages vs Buying Land First
A land and construction package bundles the land purchase and the build into one transaction. The developer sells you the block and connects you with a builder who has an approved design for that estate. You settle on the land and the construction contract at the same time, and the lender funds both in one loan.
If you're buying suitable land separately, you'll either need to purchase it outright or take out a land loan, then apply for construction finance once you've got council approval and a signed building contract. That's two settlements, two sets of costs, and usually a gap between buying the land and starting the build. Some lenders will let you roll the land loan into the construction facility, but you'll be paying interest on the land from the day you settle, even if the build doesn't start for months.
For police working shifts, a house and land package removes a layer of coordination. The developer has already dealt with the development application and council approval. The builder is familiar with the estate and the soil conditions. The lender knows the area and has likely funded other builds in the same release. That doesn't mean it's always the right option, but it does mean fewer moving parts during a period when you're managing rosters, not sitting in council offices.
How Interest-Only Repayments Work During Construction
You'll make interest-only repayments on the amount drawn down during the build. As each stage is completed and more funds are released, your repayment amount increases to reflect the higher balance. Once construction is finished, the loan converts to principal and interest repayments unless you've arranged to stay interest-only for a set period.
The alternative is capitalising the interest, where the lender adds each month's interest charge to the loan balance instead of requiring a cash repayment. That keeps your cash flow clear during the build but increases the total loan amount once you convert to full repayments. Not all lenders offer capitalised interest, and those that do will factor the additional amount into your borrowing capacity at the start.
For a senior constable building in the Hunter region, interest-only repayments during construction meant budgeting for a payment that started at around $800 per month after the first drawdown and increased to roughly $2,400 by the time the frame was locked up. Once the build finished, the loan switched to principal and interest at just under $3,100 per month. The structure gave breathing room during the build without locking in a repayment the borrower couldn't meet from day one.
What Happens if the Build Takes Longer Than Expected
Most construction loans include a build period of 12 months from the first drawdown. If the build runs over, you'll need to apply for an extension, which usually comes with an extension fee and possibly a rate adjustment. Lenders set that timeframe based on the builder's estimate and the contract schedule, so delays caused by weather, supply issues, or builder availability can push you past the original term.
If you're working rosters and the build is delayed, the main impact is how long you're making interest-only repayments on a property you're not living in yet. If you're renting while you build, that's two sets of housing costs running in parallel. Some lenders are more flexible with extensions than others, and if the delay is due to factors outside your control, most will work with you rather than force a refinance mid-build.
The build period starts from the first drawdown, not from the date you get approval. That distinction matters if there's a gap between signing the contract and the builder actually starting on-site. Make sure the builder is ready to commence building within a set period from the Disclosure Date, or you'll be paying interest on a loan that hasn't moved past the base stage.
Owner Builder Finance and Why It's Different
If you're acting as an owner builder, you're taking on the project management yourself and engaging sub-contractors directly. That changes how lenders assess the loan, because the risk sits with you instead of a registered builder. Most lenders either won't offer owner builder finance or will require a larger deposit and charge a higher rate.
The drawdown process is more complex. Instead of releasing funds to a single builder at set stages, the lender releases funds to you, and you're responsible for paying sub-contractors like plumbers, electricians, and concreters as each stage is completed. The lender will still require inspections, but you'll need to provide invoices and proof of payment at each drawdown to show the funds are going where they're supposed to.
For police officers working full-time, owner builder projects are hard to manage unless you've got genuine building experience and the flexibility to be on-site regularly. It's not a question of capability, it's a question of time. If you're rostered on afternoon shifts and a concreter needs payment approval before they pour the slab, you can't wait three days to sort it out. A registered builder handles that coordination, and the loan structure reflects it.
How Council Plans and Development Applications Affect Approval
You'll need council approval before a lender will assess your construction loan application. That means your building plans need to be submitted, reviewed, and approved by the local council. If you're building in an estate with an approved masterplan, the process is usually faster because the developer has already worked through the broader development application.
If you're building on a standalone block, particularly in a regional area or on a sloping site, the approval process can take longer. Lenders won't formally approve your construction finance until they see the stamped council plans, because those plans determine the scope of the build and the final valuation. If the council requires changes to the design, that can delay your finance approval and push back the build start date.
For a detective building in the Blue Mountains, the council required additional erosion controls and a revised driveway grade before approving the plans. That added six weeks to the approval timeline. The lender couldn't issue a formal approval until the updated plans were stamped, which meant the build start was delayed and the fixed rate lock expired. The borrower had to reapply for the rate, which had moved up in the interim. Council approval isn't just a formality, it's a dependency that affects your loan timing and your rate.
Renovation Finance and How It Differs from New Construction
A house renovation loan works on a similar drawdown structure, but the property already exists and you're usually living in it while the work happens. The lender will value the property in its current state, then assess the planned renovation to determine the end value. The loan amount is based on a percentage of the improved value, not the current value.
Renovation finance is harder to get than new build finance because the scope of work is less predictable. If you're knocking down walls, rewiring, or adding a second storey, the lender will want detailed plans, a fixed price contract, and evidence that the tradies you're using are licensed and insured. The drawdown schedule is usually less structured than a new build, because renovation stages don't always follow a linear path.
If you're planning a major renovation rather than a new build, expect the lender to be more conservative with the loan amount and more involved in the approval process at each stage. The renovation finance options available to police officers often include access to offset accounts and redraw facilities, which can help manage cash flow when you're living on-site and covering costs as they come up.
Split Loan Structures for Construction
Some borrowers split their construction loan into a fixed rate portion and a variable rate portion. The fixed portion locks in a rate for part of the loan, while the variable portion gives access to offset accounts and unlimited additional payments. During construction, both portions draw down progressively, and once the build is finished, you're paying principal and interest on both.
That structure works if you want rate certainty for most of the loan but still need flexibility to make lump sum payments from shift penalties or overtime. The downside is managing two loan accounts, two sets of repayments, and two contracts. Not every lender offers split structures on construction loans, and those that do will usually require you to nominate the split at the start, not halfway through the build.
For police officers with variable income from shift work, a split structure can smooth out repayments without locking the entire loan into a fixed rate that you can't adjust. You'll need to weigh the benefit of the offset against the cost of the slightly higher variable rate, but the option exists if it suits your situation.
What Happens at Practical Completion
Practical completion is the point where the build is finished, the final inspection is done, and the property is ready to occupy. The lender releases the final drawdown, the builder hands over the keys, and your loan converts from construction mode to a standard mortgage. You'll start making full principal and interest repayments, and the loan behaves like any other home loan for NSW Police.
The lender will order a final valuation to confirm the property is worth what they've lent against it. If the valuation comes in lower than expected, that can create a shortfall, but it's rare if the contract price was realistic from the start. Once practical completion is confirmed, you've got a finished home and a loan structure that matches it.
If there are defects or incomplete work, the builder is required to fix them before practical completion is signed off. That's why the final inspection matters. The lender won't release the last payment until they're satisfied the build meets the contract, and you shouldn't sign off on practical completion until you're satisfied either.

Frequently Asked Questions
How does progressive drawdown work on a construction loan?
Funds are released in stages as the build progresses, typically at base, frame, lock-up, fixing, and completion stages. You only pay interest on the amount drawn down at each stage, not the full loan amount upfront.
What's the difference between a fixed price contract and a cost plus contract?
A fixed price contract locks in the build cost upfront, while a cost plus contract charges actual costs plus a builder's margin. Lenders prefer fixed price contracts because the loan amount is clear from the start and cost blowout risk sits with the builder.
Do I pay principal and interest during construction?
During construction, you typically make interest-only repayments on the amount drawn down so far. Once the build reaches practical completion, the loan converts to principal and interest repayments.
What happens if my build takes longer than 12 months?
You'll need to apply for an extension, which usually comes with an extension fee and possibly a rate adjustment. Most lenders will work with you if the delay is due to factors outside your control.
Can I get construction finance as an owner builder?
Most lenders either won't offer owner builder finance or will require a larger deposit and higher rate. The drawdown process is more complex because you're responsible for paying sub-contractors directly and providing proof of payment at each stage.
