Top tips to secure construction finance in Croydon Park

What lenders look for in a construction loan application

Lenders assess construction finance differently to standard home loans because the security doesn't exist yet. They evaluate your ability to service the loan, the builder's credentials, the contract type, and whether council approval is in place before they'll consider funding.

In a scenario like this: a couple in Croydon Park wanted to knock down a dated fibro cottage on a 556 square metre block near The Strand and build a double-storey home with their registered builder. Their application included a fixed price building contract, stamped council plans, and proof they could service repayments at a higher assessment rate. The lender approved progressive drawdown across six stages, charging interest only on the amount drawn down at each inspection. The loan converted automatically to a standard home loan once the occupation certificate was issued.

The contract type matters more than most applicants expect. A fixed price contract with a registered builder gives lenders certainty around the final cost, which reduces their risk and improves your chances of approval. Cost plus contracts, where the builder charges for materials and labour with a margin, are harder to assess because the final amount can shift. Owner builder finance is available but attracts stricter serviceability tests and sometimes higher interest rates because lenders can't rely on a builder's insurance or warranty.

How the progressive drawdown works in practice

You don't receive the full loan amount upfront. The lender releases funds in instalments as the build reaches agreed stages, usually after a progress inspection confirms the work is complete. Typical stages include slab down, frame up, lockup, fixing, and practical completion.

Each drawdown triggers a Progressive Drawing Fee, which varies by lender but generally sits between $300 and $500 per inspection. Some lenders cap the total number of inspections, others charge per visit. Factor these costs into your budget from the start because they add up across a six or seven-month build. Between drawdowns, you make interest-only repayments on whatever has been released so far. Once construction is finished and the occupation certificate is issued, the loan converts to principal and interest repayments based on the full loan amount.

Lenders won't release funds for the next stage until the previous one is signed off. If your builder falls behind schedule or fails an inspection, the delay can leave you covering holding costs for longer than planned. That's why the builder's track record and their relationship with the certifier both matter during the application process.

Documents and approvals you'll need before applying

You need stamped council plans and a development application approval before most lenders will assess your application. The plans must match the contract, and the contract needs to be signed by a registered builder who holds the right insurance. Lenders also want to see a detailed progress payment schedule that aligns with their drawdown stages.

If you're buying a house and land package through a developer, the documentation is usually standardised and lenders are familiar with the builder. If you've engaged your own builder for a custom design, expect the lender to scrutinise the builder's financial position, their Australian Business Number, and whether they've completed similar projects recently. Some lenders maintain a panel of approved builders. If yours isn't on it, approval can take longer or require additional documentation.

Your own financial position gets tested harder than it would for a standard purchase. Lenders assess serviceability based on the full loan amount, even though you're only drawing down progressively. They also apply a buffer, usually around 3%, on top of the current construction loan interest rate. If you're relying on rental income from another property or plan to live elsewhere during the build, make sure those costs are accounted for in your application.

Why timing matters when buying land separately

If you're purchasing land first and building later, most lenders require you to commence building within a set period from the Disclosure Date, often 12 to 18 months. Miss that window and you may need to refinance the land loan before construction finance is approved, which adds costs and delays.

Consider a buyer who secured land in Croydon Park near George Street, planning to build once they'd saved a larger buffer. They didn't realise their lender's construction finance approval required building to start within 12 months of settlement. By the time their plans were finalised and council approval came through, the window had closed. They had to refinance the land with a different lender who allowed a longer lead time, paying discharge fees and establishment costs twice.

If you're buying suitable land with the intention to build but the timing isn't locked in, discuss the lender's timeframe requirements upfront. Some lenders offer more flexibility, others won't budge. The structure you choose at land settlement can affect your options later, so it's worth planning both stages together rather than treating them as separate decisions.

Fixed price contracts and how they protect your borrowing capacity

A fixed price building contract locks in the total cost before construction starts, which protects you from price variations and gives the lender confidence that the loan amount will cover the project. Lenders prefer these contracts because they remove uncertainty around the final valuation.

Without a fixed price, variations and cost overruns can leave you short of funds partway through the build. Lenders won't automatically increase your loan amount if the project runs over budget. You'd need to reapply, provide updated valuations, and prove you can service the higher amount. If you can't, the build stalls and you're left with an incomplete property and a loan secured against it.

Some contracts allow for provisional sums or prime cost items, which are estimates for things like tiles, appliances, or landscaping. Lenders will accept these within reason, but large provisional amounts can trigger questions about whether the contract price is realistic. Keep provisional sums tight and get quotes for anything significant before you sign.

What happens if the builder goes into administration

Your lender's interest is in the land and the incomplete structure, not in whether the builder finishes the job. If a builder collapses mid-project, you're responsible for finding another builder and funding the completion, even if that costs more than the original contract.

Most states require builders to hold home warranty insurance, which can cover some of the cost to complete or rectify defective work, but the process is slow and doesn't cover everything. Lenders won't pause your interest payments while you sort it out. That's why builder selection is as important as the loan structure. Check the builder's financial position, their history, and whether they're managing multiple projects at once. A builder stretched too thin is a risk, even if they're registered and insured.

If you're refinancing an existing loan to fund a build, the same builder checks apply. You can read more about refinancing structures on our refinancing page.

How interest rates and repayment structures differ

Construction loan interest rates are often slightly higher than standard variable rates, typically by 0.10% to 0.30%, because the lender is taking on more risk. During the construction phase, most loans are interest-only, and you only pay interest on the amount drawn down so far. Once the build is finished and the loan converts, you switch to principal and interest repayments based on the full amount.

Some lenders offer fixed rate options during construction, others only allow variable. If rates are rising, locking in a fixed rate can provide certainty, but not all lenders will let you fix until construction is complete. If you're planning to hold the property long term, consider how the repayment structure will work once the build is done. Interest-only during construction makes sense, but extending interest-only repayments after conversion can limit your options if you want to access equity later.

If you're building as an investment, the interest-only structure during construction can help with cash flow, especially if you're still paying rent or a mortgage elsewhere. Investment loan structures are covered in more detail on our investment loans page.

Construction finance isn't harder to secure than a standard loan, but it does require more documentation, tighter timing, and a clear understanding of how the drawdown process works. Most delays happen because applicants underestimate how long council approval takes or don't realise the lender needs the builder's details and contract locked in before assessment starts.
