Avoid These 5 Construction Loan Mistakes

When Construction Finance Goes Wrong in Randwick

Building in Randwick means working within strict council requirements and managing higher-than-average construction costs. The wrong loan structure or missed detail in your construction loan application can add months to your timeline and thousands to your final bill.

Most lenders only charge interest on the amount drawn down during construction, not the full approved loan amount. That makes a construction to permanent loan more affordable during the build phase than many people expect, but only if the structure matches how your builder releases progress payments.

Mistake 1: Not Confirming Your Fixed Price Building Contract Covers Everything

Your lender will ask for a fixed price building contract before approving construction finance. A contract that leaves out site costs, retaining walls, or DA conditions will create a funding gap.

Consider a medical professional building a custom home near Prince of Wales Hospital who submitted a fixed price contract for the house only. The land sloped more than expected and required $45,000 in retaining walls and drainage work. The contract listed that work as provisional, so the lender excluded it from the approved loan amount. The buyer had to find extra cash mid-build or reduce finishes elsewhere.

Randwick Council has particular requirements for stormwater management and heritage considerations in certain precincts. If your building contract lists those items as provisional or excludes them entirely, your construction funding may not cover the real cost. Ask your builder to include all site preparation, council-required works, and contingency amounts in the fixed price contract before you apply.

Mistake 2: Choosing a Draw Schedule That Doesn't Match Your Builder

Lenders release construction funding in instalments based on a progress payment schedule. Most use a five-stage or six-stage progressive drawdown structure. Your builder may expect progress payments at different points, especially if they operate on a cost plus contract instead of a fixed price.

If your lender releases funds at practical completion of the frame but your builder invoices at lockup, someone has to cover the gap. That someone is usually you. The mismatch can mean paying out of pocket for weeks or negotiating payment delays with your builder, which rarely improves the working relationship.

Before signing anything, compare your builder's progress payment finance expectations with your lender's construction draw schedule. If they don't align, ask your broker to find a lender whose structure does. Some lenders offer flexible drawdown terms that can be tailored to a specific building contract, but you need to request that upfront.

Mistake 3: Underestimating How Long Council Approval Will Take

Randwick Council is thorough, and that shows in approval times. A development application for a new home or substantial renovation can take several months, longer if neighbours object or if your site falls within a heritage conservation area.

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, your loan approval may expire before you can start. Reapplying means updated income documents, a new credit check, and possibly different construction loan interest rates.

Before lodging your loan application, check where your DA sits in the council process. If approval is still weeks away, it may be worth waiting rather than rushing the loan and risking expiry. Some lenders allow extensions, but they are not automatic and often come with a fee.

Mistake 4: Not Accounting for the Progressive Drawing Fee

Lenders charge a fee each time they release funds during construction. This is called a Progressive Drawing Fee, and it usually sits between $300 and $500 per drawdown. Over five or six progress payments, that adds $1,500 to $3,000 to your build cost.

That fee is separate from your loan amount and usually needs to be paid upfront or deducted from each progress payment. If you have not budgeted for it, it reduces the cash available for your builder at each stage, which can delay the next phase of work.

Ask your broker to confirm the total progressive payment fees when comparing construction loan options from banks and lenders across Australia. Some lenders waive or cap these fees, especially for clients with strong equity or existing relationships. Including this cost in your overall budget prevents surprises once the build starts.

Mistake 5: Using All Your Savings on the Deposit Without Keeping Cash for Build Variations

Construction rarely goes exactly to plan. Even with a fixed price building contract, variations happen. You might want to upgrade benchtops, move a window, or add power points. Each variation costs money, and most builders expect payment before starting the extra work.

If you have used every dollar of your savings to meet the deposit and cover upfront costs, you will have no buffer for changes or unexpected expenses during the build. That can mean delaying decisions, settling for cheaper alternatives, or scrambling to access extra funds mid-project.

Randwick's proximity to the coast and its mix of older subdivisions means some sites come with unexpected challenges once excavation begins, from sandstone to old fill material. Keeping a reserve of at least 5% of your build cost gives you room to respond without halting the project or going into debt outside your mortgage.

Getting the Structure Right From the Start

A well-structured construction to permanent loan allows you to build with confidence. Your lender should release funds in line with your builder's schedule, your contract should cover all required works, and your budget should include fees and contingencies.

If you are planning to build in Randwick, whether it is a custom design near Coogee or a knock-down rebuild closer to the university precinct, the structure of your construction finance matters as much as the interest rate. The difference between a smooth build and a stressful one often comes down to what was agreed before the first slab was poured.
