Construction Home Loans

* Enquiring will not affect your credit score

If you want to build a home or residential investment property in Australia, chances are you’ll need a construction home loan. Construction home loans can also be used for major renovations in some cases.


How construction home loans work

How do construction home loans work?

Construction home loans are designed to fund the building of residential homes or investments. This is how they work:

  • Your builder provides the lender with a quote detailing the total cost for the project broken down into each stage of construction.
  • The lender will release funds as needed to complete each stage of the construction - this is called a ‘progressive drawdown’.
  • During the construction phase you’ll only pay interest on the amount you’ve drawn down. 
  • You’ll only make interest payments during construction (not principal repayments). 
  • When the build is finished your construction loan will revert to a normal home loan and you’ll start making both principal and interest repayments. 

Just like with a normal home loan it’s best to have a deposit equal to 20% of the build cost before applying. You may be approved with as little as 5% but you may be charged extra fees such as Lenders Mortgage Insurance (LMI) along with higher interest rates.

How to apply for a construction home loan

How to apply for a construction home loan

When applying for a construction loan lenders will need all the usual documentation required when taking out a normal home loan, including:

  • Proof of identity 
  • Proof of income 
  • Proof of debt 
  • Proof of savings, investments and assets 
  • Record of spending 
  • Gift letter (if part of your deposit has been given to you as a gift)  

You’ll also need to provide a number of other documents to your lender including:

  • A building contract

When you engage a builder they’ll provide a contract that includes:

  • An outline of each construction stage 
  • A progress payment schedule 
  • A construction timeline
  • Total costs for the project 

This document gives lenders an idea of when you will be drawing down on the loan, and when the project will be completed.

  • Building plans

This will also be provided by your builder or architect and will include all details of your home including layout, size, specifications, materials used and more.

  • On completion valuation

Before your construction loan is formally approved your lender will need an estimate of the home’s value on completion by a registered valuer. To do this the valuer will need both the building contract and the building plans. 

They will estimate the value of the home on completion and compare it to recent sale prices of comparable homes in the area. This is done to ensure you’re not overspending on your build, and that your home will be worth more than the loan amount when completed.

Progress payments for construction home loans

Progress payments for construction home loans

Construction home loan progress payments are usually made in five key stages of the build. Here’s a rough breakdown of the total cost and duration of each stage:

  • 1. Foundations - Laying foundations of the house and installing plumbing. 
  • 2. Frame - Building the frame of your property including roofing, windows, walls and trusses. 
  • 3. Lock up - Construction of internal walls, doors and insulation of the home. This includes everything that is required to be able to ‘lock up’ your property and make it weathertight. 
  • 4. Fit-out - The finer details of the home are added such as shelving, kitchen & bathroom cabinetry, tiles and internal cladding. 
  • 5. Completion - Everything that is required to complete the home. This may include installation of retaining walls or fences as well as cleaning of the site.

Owner-builder construction loans

To secure a construction loan, you’ll usually need to sign a contract with a qualified builder. If you want to build your home yourself, you’ll need to apply for an owner builder construction loan, offered by a select few lenders. 

Getting approval can be difficult for this type of loan because lenders view owner-builder projects as more risky, and more prone to cost overruns. If you’re a licensed builder you may be able to secure a loan for up to 80% of the build’s cost - if you’re not you may only be able to borrow 50-70%. 

Because lenders are so strict with these types of loans, before you apply you should make sure:

  • You have a deposit of at least 20% if possible. 
  • You have a good credit score and minimal debt. 
  • You have a detailed plan for construction including cost estimates and quotations for tradesmen and materials.  

Since not all lenders offer these types of loans it may be better to speak to a mortgage broker or financial advisor to help find the right fit.


Construction home loans summary

Summary

Construction home loans are loans specifically designed to fund the construction of residential homes and investments. Usually your lender will approve your loan up to a certain limit then allow you to draw down (withdraw) funds to cover building costs at each stage of construction. 

To apply for a construction loan you’ll need:

  • A deposit of at least 5% but preferably more than 20%
  • A cost-including building contract and building plans prepared by a registered builder

Before your lender approves your construction loan a registered valuer will estimate the value of the home upon completion. Once your loan is approved you’re free to start construction! 

Before you apply it’s a good idea to check if you’re eligible for the HomeBuilder scheme as you may be able to access a tax-free grant of up to $25,000.
