What is a Construction Loan
Friday 18 September 2026
Financing is one of the biggest questions buyers have when building a new home. While most people are familiar with a standard home loan or mortgage, construction loans work a little differently because the home is built over time rather than purchased as a finished property.
Understanding how construction loans work before you begin can help make the building journey much less overwhelming. From progress payments to interest only repayments, knowing what to expect will give you greater confidence throughout the process.
What Is A Construction Loan?
A construction loan is a type of home loan specifically designed to fund the construction of a new home. Rather than providing the full loan amount upfront, the lender releases funds in stages as construction progresses.
This differs from purchasing an established home, where the full loan amount is generally provided at settlement.
Construction loans are commonly used for house and land packages, knockdown rebuild projects and custom home builds. They allow buyers to finance the construction process while only paying interest on the money that has actually been drawn down.
How Does A Construction Loan Work?
Although each lender has its own requirements, the process generally follows the same steps.
1. Obtain Pre Approval
The first step is understanding how much you can borrow. A lender or mortgage broker will assess your income, expenses and borrowing capacity to determine how much you may be eligible to borrow.
Having pre approval also helps you set a realistic budget before selecting your home design.
2. Purchase Your Land
If you are building a house and land package, the land is usually purchased first. Some buyers may already own their land before applying for a construction loan.
The land purchase forms part of the overall finance arrangement.
3. Sign Your Building Contract
Once you've chosen your home design and finalised your selections, you'll sign a building contract with your builder.
Your lender will use this contract as part of the loan assessment, as it outlines the agreed construction cost and payment schedule.
4. Receive Unconditional Loan Approval
Before construction begins, your lender will complete its final assessment and issue unconditional approval, provided all requirements have been met.
Once approved, construction can commence.
5. Funds Are Released During Construction
Unlike a standard mortgage, your lender does not release the full loan amount at once.
Instead, funds are paid to the builder at agreed construction stages using what is commonly known as a draw down schedule.
This ensures payments are linked to completed work throughout the build.
6. The Loan Converts To A Standard Home Loan
When construction is complete and your new home receives its Certificate of Occupancy, the construction phase ends.
At this point, your loan generally converts into a standard home loan, with repayments changing from interest only to principal and interest, depending on your loan agreement.

What Are Progress Payments?
One of the biggest differences between a construction loan and a standard mortgage is how payments are made.
Rather than paying the builder in one lump sum, construction loans use progress payments. These payments are made at agreed stages throughout the build as work is completed.
Typical construction stages include:
Deposit
Base
Frame
Lock Up
Fixing
Completion
Before each payment is released, your lender may confirm that the relevant construction stage has been completed.
Because funds are progressively drawn down throughout the build, you generally only pay interest on the amount that has been released, rather than the full loan amount from day one.
Construction Loan Vs Standard Mortgage
Although both products help finance a home, they are designed for different situations.
A standard home loan is used to purchase an existing property. The full loan amount is typically provided at settlement, and repayments begin on the entire balance immediately.
A construction loan is designed specifically for building a new home. Funds are released progressively throughout construction, and borrowers generally make interest only repayments on the amount that has been drawn down until the home is complete.
For buyers building a new home, a construction loan provides a finance structure that matches the construction process.
What Do You Need To Apply For A Construction Loan?
While lender requirements vary, most construction loan applications require:
A deposit that meets the lender's lending criteria
A signed building contract
A fixed price contract
Details of the land purchase
Plans and specifications for the home
A licensed builder
Evidence that you meet the lender's borrowing requirements
Providing complete documentation early can help reduce delays during the approval process.

Can First Home Buyers Get A Construction Loan?
Yes, construction loans are commonly used by first home buyers building a new home.
Depending on your circumstances, you may also be eligible for government assistance, including the First Home Owner Grant or stamp duty concessions.
For many buyers, combining these incentives with a construction loan can make building a new home a more accessible pathway into the property market.
Common Questions About Construction Loans
Construction loans are designed to be flexible, but buyers often have questions about what happens if circumstances change during the build.
Changes to your home after signing the building contract may require contract variations, which can affect both your building contract and your finance. It is important to speak with both your builder and lender before making significant changes.
Many buyers also ask what happens once construction finishes. Once your home is complete and all lender requirements have been met, the construction loan generally transitions into a standard home loan and regular mortgage repayments begin.
Choosing The Right Finance Partner
Construction loans involve more moving parts than a standard mortgage, so having the right advice early can make the process much easier.
While Eight Homes does not provide financial advice, we work closely with our finance partner, Inovayt, who can help buyers understand their borrowing capacity, construction loan options and the finance process before construction begins.
Seeking finance advice early can help you understand your budget, avoid delays and move forward with confidence.
Understanding Construction Loans With Confidence
Construction loans are designed specifically for the building process, providing funding as your new home progresses through each stage of construction.
By understanding how construction loans work, how progress payments operate and how they differ from a standard mortgage, you'll be better prepared for your home building journey.
Whether you're building your first home or your next one, understanding your finance options is an important first step towards a successful build.

How do progress payments work on a construction loan?
Progress payments allow your lender to release funds to the builder as each stage of construction is completed. This means you generally only pay interest on the amount that has been drawn down rather than the total approved loan amount.

How much deposit do I need for a construction loan?
The deposit required depends on your lender, financial circumstances and the loan to value ratio. Speaking with a lender or mortgage broker early in the process will help you understand how much you'll need.
When does a construction loan convert to a standard mortgage?
A construction loan generally converts to a standard home loan once construction is complete, the required inspections have been finalised and your lender has released the final progress payment.
