Home Loans for Owner Builders
How the Banks See Owner Builders
If you’re already a licensed builder, you’re likely to have several contacts in the building industry that can make building your own home much more affordable. When you build it yourself, you’re by-passing the middle-man and potentially saving yourself plenty of money on construction costs.
Unfortunately, the bank won’t always see it this way. There are only a few home loan lenders in Australia that will consider applications to fund owner builder projects, and all of those will require a minimum of 20% equity.
To a bank assessor, an owner builder mortgage represents a greater risk than a construction being undertaken by a licensed builder. This may be because many DIY builders under-estimate their costs severely. Some owner builders tend to change their plans part way through construction, or go way over budget. There were also those who just didn’t finish the project, leaving the bank with no security property.

How Does A Construction Loan Work?
It could also be because the bank has no guarantee that the builder in question has the requisite experience in actually building a home and organising various tradespeople in order to complete a project of this size.
Differences in Valuation Amounts
Most owner builders will estimate the completed cost of the home after they’ve finished building it as being far higher than the amount it cost them to build.
Yet the bank won’t see it the same way you do. Be aware that the construction valuations (often called “to be erected” valuations, or TBE) will be valued differently to an established property. You will find that the valuer will take the land value and add only the construction costs to it that you supply.
This is not going to be the final home value amount, but it is the figure the bank will take into consideration. They will then lend you up to 80% of this TBE valuation amount.
Progressively Drawn Down Construction Loans
When you’re building a home as the owner builder, you might expect that the bank will forward you the amount of money you applied for upfront. It never works this way.
You will be asked to provide the bank with your proposed building plans, site plans and a complete, itemised estimation of the costs associated with your construction. There will also be a lot of other documentation you’ll need to provide, so be sure to ask for a checklist to ensure you’re supplying all you need.
Construction loans are progressively drawn down in stages as each stage of your home is completed. For example, you hire the contractors you need to prepare your site-works and to dig your foundation trenches, lay the under-floor plumbing, prepare the slab and pour the concrete. When this stage is complete, you let the bank know and they forward the funds to cover this stage.
Your funds are released from your mortgage amount and you move onto the next stage, ordering timber for the first fix stage of construction, and so on.
Unfortunately, you might find that some contractors won’t be happy to wait for the bank to release your money. This means you may need to have some reserve funds available to help pay for any materials you need to buy in order to complete each stage before the bank will release any funds.
It is very important that you don’t run out of money during these phases, as the bank will not top up your mortgage during the construction process. Be careful about estimating your costs and always ensure you have back-up funds, or you’ll end up in a lot of trouble.
