A construction loan is generally paid out in stages as the build progresses, not as one lump sum. For an owner builder, matching your own budget and schedule to those stages is one way to keep control of cash flow when interest rates move. This guide explains how staged payments are described by NSW Government sources, what the latest official rate and lending data show, and what to ask a lender. This is general information, not financial advice.
What is a construction loan?
Moneysmart (the Australian Government’s money guidance site, run by ASIC) defines a construction loan as “a type of home loan for people who are building their own home” (Moneysmart glossary, last updated 1 October 2019). That is a short definition, so the rest of this guide leans on the NSW Government’s planning information about how these loans work in practice.
How staged (progress) payments work
The NSW Planning Portal’s MyHome Planner describes the build phase of a project with a construction loan like this (NSW Planning Portal, Build phase; the page shows no publication date):
- Your lender needs to formally approve that construction can begin, and sends a formal commencement letter.
- Construction must start within 12 months of the disclosure date on your loan contract.
- Payments to the builder are made in progressive payments at each stage of the build, and the schedule is set out in the building contract.
- The page lists six stages: site preparation, foundations, frame, lock-up, fit-out and practical completion.
- When a payment is due, the builder issues an invoice. You authorise and sign it, which confirms the stage is complete, and then send it to your lender.
- A builder cannot ask for a progress payment in advance of the work being carried out.
- You must keep making loan repayments throughout the build.
An important point: that page is written for people using a builder, and it does not mention owner builders. How a lender treats an owner builder (for example, who signs off a stage, or what documents they want) is a question for each lender. We have not assumed any lender’s policy.
What the official data shows right now
The cash rate
The Reserve Bank of Australia (RBA) publishes the cash rate target, which is the interest rate it sets for overnight money between banks. Its table shows the following recent changes (RBA cash rate target page, viewed 2 November 2026; the page shows no last-updated date):
- 18 March 2026: increased by 0.25 percentage points, to 4.10%
- 6 May 2026: increased by 0.25 percentage points, to 4.35%
- 17 June 2026 and 12 August 2026: no change (4.35%)
- 30 September 2026: increased by 0.25 percentage points, to 4.60%
The cash rate is not the rate on your loan. Lenders set their own rates, and the RBA table does not tell you what any lender charges. It also says nothing about where rates will go next, and we are not forecasting.
Home lending
The ABS (Australian Bureau of Statistics) Lending Indicators release for the June quarter 2026, published 14 August 2026, shows the following for owner-occupier housing finance across Australia, seasonally adjusted and excluding refinancing (ABS Lending Indicators, June quarter 2026):
- 81,626 new loan commitments, down 3.3% in the June quarter 2026 and down 1.6% from the June quarter 2025
- $60.5 billion in new loan commitments by value, down 1.9% in the June quarter 2026 and up 6.0% from the June quarter 2025
What this does not show: the page we read gives no separate figure for construction loans to owner builders, and no NSW loan count or value. So these national numbers should not be read as a measure of owner builder lending.
Matching your budget and schedule to the stages
Because money is released stage by stage, your cash flow follows your program. A few practical ideas, which are our suggestions rather than official requirements:
- List your expected costs by stage, using the same stage names your lender uses, so each payment request lines up with a block of work.
- Build a schedule that shows when each stage is likely to finish, so you know roughly when you will need funds. Safe Rite’s free Auto-Schedule and Auto-Budget tools are designed for this kind of planning.
- Keep a contingency in your budget. Our costs, savings and risks guide covers owner builder costs in more detail.
- Remember that repayments start while you are still building (the Planning Portal says you must continue making payments throughout the build), so allow for them in your cash flow.
Questions to ask a lender
- Do you lend to owner builders, and what do you need from me (for example, a permit, plans, a budget or quotes)?
- How many stages are there, and what evidence do you need before releasing each payment?
- How quickly are invoices paid once I submit them?
- How is interest charged during construction, and is the rate fixed or variable?
- What happens if the build runs late or costs more than planned?
Before you start, make sure you have your owner builder permit. Our guide to getting an owner builder permit in NSW explains the steps, and the NSW owner builder course from Safe Rite (RTO 45002) is a nationally recognised course for owner builders. The course is normally $219, currently reduced to $189: you register free and pay when you pass.
Frequently asked questions
Can an owner builder get a construction loan in NSW?
The official pages we read do not say. Lender policies differ, so ask each lender directly what they require from owner builders before you commit to a plan.
How are construction loan payments made?
According to the NSW Planning Portal, payments are made in stages as the build progresses, following the schedule in the building contract. The builder invoices, you sign, and your lender pays.
Do I pay interest on the full loan from day one?
We could not confirm this from an official source. Ask your lender how interest is calculated during construction.
Does the RBA cash rate decide my loan rate?
No. The cash rate is the RBA’s target rate, and each lender sets its own loan rates. The cash rate is one factor lenders consider, but check your lender’s actual rate.
What if I disagree with a progress payment?
The Planning Portal advises continuing to make progress payments even where there is a defect or dispute with a builder. For your own situation, check the official guidance or seek advice.
What we could not verify
- Whether, and on what terms, lenders offer construction loans to owner builders.
- How interest is charged during construction.
- Any Moneysmart page dedicated to construction loans (only a glossary definition was found).
- Construction loan or owner builder lending figures for NSW (the ABS page we read does not show them).
- The publication dates of the RBA table page and the Planning Portal page (neither shows one).
