10 Things to Know Before Building Your Dream Home

Building a custom home in the Hills District starts with understanding how construction finance works differently to a standard home loan.

You don't receive the full loan amount upfront. Instead, funds are released progressively as each stage of the build reaches completion and passes inspection. This protects both you and the lender, but it also means your budget, timeline, and relationship with your registered builder need to align from day one. The decisions you make before the first slab is poured will determine whether the build stays on track or stalls halfway through.

How Construction Loans Release Funds in Stages

Construction loans operate on a progressive drawdown structure. The lender only releases funds after each stage of the build is complete and verified by an independent inspector. Stages typically include base, frame, lock-up, fixing, and completion. You only pay interest on the amount drawn down so far, not the full approved loan amount. This keeps your repayments lower during the build, but it also means you need to coordinate draw requests with your builder's progress payment schedule. If your builder expects payment before the lender releases funds, you'll need to cover that gap temporarily or negotiate timing with both parties.

Fixed Price Building Contracts Reduce Funding Risk

Lenders strongly prefer fixed price building contracts over cost plus arrangements. A fixed price contract locks in the total build cost before construction begins, which means the lender knows exactly how much they're funding and you know what your final loan amount will be. Cost plus contracts, where you pay the builder's actual costs plus a margin, create uncertainty for both parties. Some lenders won't approve construction finance without a fixed price contract in place. If you're working with a custom builder in Castle Hill or Kellyville, confirm the contract type before you start the construction loan application process.

Council Approval and Development Applications Come First

Your lender will require evidence of council approval before they release the first drawdown. In The Hills Shire, this typically means a Construction Certificate issued after your Development Application has been approved. The DA process can take several months depending on the complexity of your design and whether your block sits in a heritage conservation area or bushfire-prone land. If you're building in Bella Vista or Baulkham Hills where larger blocks and custom designs are common, factor in extra time for council plans and any required amendments. Most construction loan approvals include a condition that you must commence building within a set period from the Disclosure Date, often six to twelve months. If council delays push you past that deadline, you may need to reapply or accept revised loan terms.

Land and Construction Packages Versus Buying Land Separately

You can structure construction finance as a single loan covering both the land purchase and the build, or as two separate transactions. A land and construction package from a developer often includes suitable land and a builder already attached, which can simplify approval. If you're buying land separately in Northmead or Parramatta and then engaging your own builder, the lender will require a valuation of the land and a separate assessment of the build cost. Timing becomes more complex because you'll settle on the land first, often on interest-only repayment options, and then draw down construction funds over the following months. Both structures work, but the single-package approach tends to move faster through approval because the lender sees less execution risk.

Interest-Only Repayments During the Build Phase

Most lenders offer interest-only repayments during construction, calculated only on the amount drawn down so far. Consider a scenario where you've drawn $200,000 for the base and frame stages of a $600,000 build. You'll pay interest on $200,000, not the full loan amount. This keeps cash flow manageable while you're still paying rent or living elsewhere. Once the build completes and you convert to a standard home loan, repayments switch to principal and interest unless you negotiate otherwise. Some lenders allow you to make additional payments during construction to reduce the balance before conversion, which can lower your ongoing repayment once you move in.

Progress Payment Schedules and Builder Coordination

Your builder's progress payment schedule and the lender's drawdown structure need to match. Builders typically work to a five-stage payment schedule: deposit, base, frame, lock-up, fixing, and completion. The lender's progress inspection schedule may not align perfectly with those stages. In our experience, the most common friction point occurs at lock-up, where builders expect payment for roof, windows, and external doors, but the lender's inspector wants to see additional internal work before releasing funds. Discuss this with both your builder and your broker before signing the building contract. If there's a gap, you may need to negotiate a delayed payment clause or arrange a short-term buffer in your own savings.

Progressive Drawing Fees and Other Construction Loan Costs

Lenders charge a Progressive Drawing Fee each time they release funds and send an inspector to verify the stage is complete. This fee typically ranges from $300 to $500 per drawdown, and with five or six stages in a typical build, the total cost can reach $2,000 to $3,000. Some lenders cap the number of inspections or offer a flat fee structure. You'll also pay interest during construction, council fees for the DA and Construction Certificate, insurance for the build period, and potentially holding costs if you own the land before construction begins. These costs sit outside the build contract and loan amount, so they need to come from your own savings or be factored into your overall borrowing capacity.

Owner Builder Finance Requires Different Approval Criteria

If you're acting as an owner builder rather than engaging a licensed head contractor, most mainstream lenders won't provide construction finance. Owner builder finance is available through specialist lenders, but it comes with higher interest rates, lower loan-to-value ratios, and more stringent drawdown conditions. The lender will often require evidence that you've engaged licensed plumbers, electricians, and other sub-contractors before releasing funds for each stage. If you're considering this route in the Hills District, where council and insurance requirements are already detailed, weigh the interest rate difference against the additional coordination and risk you're taking on. For most buyers, a registered builder and standard construction loan delivers better value.

Converting to a Standard Home Loan After Completion

Once the build reaches practical completion and you receive the Occupation Certificate, the construction loan converts to a standard home loan. This is called a construction to permanent loan, and most lenders structure it this way from the outset so you don't need to reapply or pay a second set of establishment fees. The interest rate may change at conversion, particularly if you were on a discounted construction rate during the build. The loan term also resets at this point, so a build that took nine months will still give you a 30-year loan term from the date of conversion, not from the date of your original approval. Confirm the conversion terms in writing before you sign the initial loan documents.

Why Working with a Broker Protects Your Build Timeline

Construction loans involve more moving parts than a standard purchase. You're coordinating a builder, a lender, council approvals, progress inspections, and drawdown timing across a period of months. A broker who works regularly with construction finance can match you with lenders who understand local council processes in The Hills Shire, offer reasonable drawdown schedules, and approve owner-occupier builds without unnecessary conditions. They'll also structure the loan to align with your builder's payment schedule and flag potential timing issues before they delay the build. If you're planning to build your custom home in Kellyville, Castle Hill, or anywhere across the Hills District, the time you invest in setting up the finance correctly will determine whether the build delivers the outcome you're planning for.
