Can I get a home loan to build my own house?

To build your own property, you’ll usually have to apply for a construction loan, which differs to a regular home loan. Most lenders release the money in instalments, relating to each stage of construction.

Fans of Grand Designs, The Block or House Rules might think building a house from scratch is easy. But a home isn’t built in a day.

If you choose to build your own home, you’ll need what’s called a construction loan. Lenders don’t tend to offer traditional loans to those wanting to build their own properties – the risk involved puts some lenders off entirely.

To begin with, they have to consider the possibility you never finish the project, or that you overspend on construction. Either scenario could lead to you defaulting on your loan repayments.

What is a construction loan?

A construction loan is a loan sought to facilitate building of some kind – be it a house or renovations, knock down or rebuild.

Construction loans, accessible once a buyer has purchased land, enable borrowers to access their loan amount in stages. In other words, lenders structure the loans so you receive a payment only when you reach a new stage of construction.

This means the borrower doesn’t have to make repayments on the full loan until they are ready to move into the house. If your lender has released 60% of the loan, you only make repayments on that 60%.

It also protects the lender as it prevents the borrower from spending the entire loan early on and ending up with nothing to finish the project.

What are the different stages of construction?

Once you’ve found a reputable builder and drawn up plans for your property, you’ll get a building contract which includes the cost, construction terms and a Progress Payment Schedule (PPS) which is a schedule of the payments you’ll need to make to your builder.

Your PPS will typically include 5 or 6 stages of construction, from foundations to framing, fit out and finishes.

How does a construction loan work?

A construction loan aligns with the payment scheme your builder puts in place. At the end of each stage of construction, your builder should give you an invoice. You send this invoice to your lender, and they release the next loan payment for the project. Your builder receives their payment and moves onto the next stage.

Your lender will provide a percentage of your construction loan for each stage, which may look something like this:

Banks and lenders may structure their construction loans slightly differently. Below is an example of a Westpac 5 stage loan.

UNO works with many lenders which offer competitive construction loans, including Bankwest and St George, both of which have dedicated progress payment teams to help with the drawdown process.

What are the steps in the construction process?

The stages of the construction process have been outlined above. There are other things to know before you get started though.

For one, most lenders require that construction commence within 6 months from the Disclosure Date on the home loan contract. Construction may also need to be completed within 24 months.

In addition to your loan application documents, you’ll also need to supply to your lender:

  • A signed and dated building contract
  • Your Progress Payment Schedule
  • Council approved plans for your construction
  • Quotes for any additional work to be funded by the loan

Do you have to put a downpayment on a construction loan?

As with standard home loans, the greater your deposit, the less risk you pose to the lender. Because many people go over budget when building a home, it’s good to save as much as you can before commencing work – and continue to save throughout the process.

How do draws work on a construction loan?

A construction loan aligns with the progress payment scheme your builder puts in place. Each progress payment is called a draw down and interest will be charged on the amount drawn down at the time.

How much interest will I pay on a construction loan?

Unlike standard home loans where you pay interest on the full amount from the start, with a construction loan you only pay interest on what you draw down. So if you draw down $50,000 of a $500,000 loan to begin with, you’ll only pay interest on that $50,000. You’ll pay interest on the rest as the construction continues and you draw it down.

I have gone through 6 different mortgage brokers prior to meeting Andrew Wyers. He is the most patient mortgage broker I’ve encountered and also the most knowledgable about the bank’s lending process and products available. It took me 1 year to find a house I was happy with and Andrew was always there to assist with any issues or questions I had; he always return my phone call, even on the weekends or when his away on holidays. The loan process was smooth and I had no complications. The process with Andrew was again nice and easy, he took the time to find and put together the right package that was suited to my situation. I have recommended Andrew to my family & friends and everyone have been grateful and completely satisfied with his service.

I had not dealt with Scott or UNO before finding them on the internet. Even as an Australian citizen living and working overseas, I knew obtaining a loan would be difficult. However, Scott went above and beyond what I expected from a mortgage broker. I genuinely don’t think you could find another company that works as hard as they did to get my home loan approved. I cannot recommend them highly enough. Everyone I dealt with at UNO were extremely professional and helpful. If you are looking for a broker, you would be mad not to give them a go. Thanks to Scott Wilkinson, Dalby Bajwa, Jena Lasquite and Andrew Pacini. Shaun.

I am writing this summary in support of recommending Mike Parsons as a Mortgage Broker. At the time of writing this, I have known Mike for 4 years and he has executed 4 mortgages deals for me (including 2 refinances) over that time. Mike has provided me incredible service as a mortgage broker as follows : - Works painstakingly on getting the scenarios together to provide you options that optimize your position. - Works inordinate hours on the detail necessary to support the scenarios. - Mike keeps you updated on the status and progress of the applications and also helps you work through answering questions and any complexities that may arise. -In my cases, given the complexities and timings of my situations , these application processes would take many weeks to finalize . Mike never gave anything other than utter commitment and focus to getting the job done. Mike acts as a true business partner throughout this whole broker /mortgage journey. I simply would only go to Mike for any future dealings on getting a loan from a bank (and as will my kids in the future !) . There is no way a bank (I have seen anyway) would provide this kind of time nor service to a customer. You can rest assured that once Mike has done the deal, you have ended up with the most optimized position taking into account all the variables/scenarios in play. Scott Hutchinson

I've worked with Scott Wilkinson for my last 2 properties and he's been excellent. He sourced multiple options and didn't push a specific bank, tailoring his recommendations to me based on my requirements. I was specifically requesting a "medico loan" and Scott could navigate that extra requirement with expertise. When I was initially working with Scott, I was also trialling 2 other brokers and neither of those 2 had the same breadth of lenders, or could provide the same deals. I've referred multiple buyers to Scott and his team; one of them said to me after working with him, "how'd you find this guy, he's so good compared to all the other broker's I've worked with!" I'm going into my next purchase with Scott as my broker partner again. I recommend him to everyone
