Building it yourself? How does owner builder finance work?

With a small group of lenders, usually at a lower loan-to-value ratio, often around 60 to 70 per cent, and with detailed costings, the owner-builder permit and a contingency. Some lenders will not fund owner-builder work at all.

The saving on the build needs to be weighed against a larger deposit and a tighter loan.

Why are lenders cautious?

A family on the porch of their home
  • A construction loan is funded against a completed dwelling that does not exist yet.
  • With a licensed builder on a fixed-price contract, the lender has a party contractually obliged to deliver it and an insurer standing behind that obligation.
  • With an owner builder, the lender is relying on you to finish, on budget, while also living your life.
  • That is a different risk and the terms reflect it rather than punishing you.

What do the terms typically look like?

A family together in their backyard
  • Lower maximum loan-to-value ratios than a builder-contracted project, meaning more of your own money in.
  • More documentation, including your owner-builder permit, detailed costings and often evidence of relevant experience.
  • Progress payments assessed more conservatively, sometimes released in arrears against completed and inspected work rather than against a contract schedule.
  • Fewer lenders willing to participate at all.

The permit and insurance position

In NSW an owner-builder permit is required above a threshold value of work, and obtaining it involves completing the required training. None of this is a lending question, but all of it affects whether the lending is available.

Home warranty insurance rules also differ for owner builders, and there are consequences at resale within a defined period that your solicitor should explain before you commit.

The arithmetic

Owner building typically saves the builder's margin and project management cost. Against that, set the reduced borrowing capacity, the longer build time, the cost of your own time, and the risk that trades quoted individually total more than expected.

It can absolutely be worth it for someone with genuine construction experience and time. It is rarely worth it as a way to make a marginal project work.

What does an owner-builder file need?

Four things, and the first two decide whether the file is possible at all.

  • Owner-builder permitRequired in NSW above a threshold value of work, and obtained through the prescribed process before construction.
  • A larger depositMaximum loan-to-value ratios are generally lower than for a builder-contracted project. More equity is required.
  • Detailed costingsTrade-by-trade quotes rather than a single contract figure, plus a contingency the lender can see.
  • Relevant experienceSome lenders ask about it directly. A first-time owner builder on a complex project is a harder file.

Common questions about owner builder

Can I get a loan as an owner builder?

Sometimes: some lenders permit it and many decline. Those that do lend at lower maximum ratios and want more documents, including your permit and detailed costings, so find out which lenders participate before committing to the path.

How much less can I borrow?

Expect a lower maximum loan-to-value ratio than for a builder-contracted project, so more of your own funds go in; the reduction depends on the lender and the project. Quantify it early, because it can cancel out the savings owner building was meant to deliver.

Do I need an owner-builder permit?

In NSW, above a threshold value of work, yes, and obtaining it requires completing prescribed training. There are also consequences for selling within a defined period after completion. Your solicitor should walk you through both before you commit.

What about home warranty insurance?

The rules differ for owner builders compared with licensed builders, and this affects both the lending and any future sale. It is one of the specific areas where advice from your solicitor is worth more than a general explanation on a website.

Is it worth it?

It can be, for someone with genuine construction experience, time available and a project of manageable complexity. It is rarely the right answer as a way to make numbers work that otherwise would not, because the reduced borrowing capacity and longer timeline often absorb the saving.
