What Are Development Finance Rates in Australia in 2026?

If you've got a development project in front of you, one of the first questions you're going to ask is: what will this cost me to fund?

The honest answer is: it depends. But "it depends" is only useful if you know what it depends on. This article breaks down what rates look like across senior debt, mezzanine finance, and private credit in 2026 — and more importantly, what drives them up or pulls them down.

Senior Construction Loan Rates (Bank and Non-Bank)

Senior debt is the first-ranking loan — typically 60–70% of the Gross Realisation Value (GRV) for residential builds, slightly lower for commercial.

In 2026, indicative senior construction loan rates in Australia sit roughly as follows:

  • Major bank (Big 4): BBSY + 1.80–3.60%

  • Tier 2 bank / regional lender: BBSY + 3.00–4.50%

  • Non-bank construction lender: BBSY + 4.50–6.50%

Major bank pricing is expressed as a margin over the Bank Bill Swap Rate (BBSY) — the standard floating rate benchmark for commercial construction lending in Australia. The all-in rate moves as BBSY moves; as of mid-2026, BBSY sits around 4.10–4.20%, putting Big 4 effective rates roughly in the 5.9–7.8% p.a. range depending on deal quality and margin negotiated.

These rates are typically expressed as interest-only during the construction period, with interest capitalised into the loan and drawn progressively as work progresses.

Major banks will price at the lower end but come with conservative LVR caps (often 65% GRV), more restrictive presale requirements (typically 100% of debt covered), and longer credit approval timelines — often 8–12 weeks.

Non-bank lenders price higher but can move faster (2–4 weeks), will consider lower presale coverage, and are generally more flexible on project type and borrower structure.

Mezzanine Finance Rates

Mezzanine debt sits behind the senior loan — typically from 65–75% GRV up to 85–90% GRV — filling the gap between what the senior lender will fund and what the developer has as equity.

Mezzanine is priced to reflect the elevated risk of its subordinate position. In 2026, expect:

  • Institutional mezzanine (fund managed): 12–16% p.a.

  • Private mezzanine / family office capital: 14–20% p.a.

  • Preferred equity structures: 15–22% p.a. (often structured as IRR return rather than coupon)

Mezzanine is almost always interest-capitalised and paid out at completion alongside the senior lender from settlement proceeds. The effective cost needs to be modelled against the return on equity it unlocks — a well-structured mezz facility can meaningfully improve your equity IRR if the project performs.

Private Credit and Bridging Finance

Private credit covers a wide range of non-bank, non-institutional lending — family offices, high-net-worth syndicates, credit funds operating outside standard APRA constraints.

This market moves fast and is less price-sensitive than the institutional market, but it comes with a different risk/return profile:

  • Short-term bridging (3–12 months): 1.0–2.0% per month (12–24% annualised)

  • Private first mortgage construction: 9.5–13% p.a.

  • Private second mortgage / residual stock: 13–18% p.a.

Private credit fills gaps the institutional market won't touch — complex borrower structures, low presales, non-standard security, time-critical settlements. The price reflects availability and speed, not just credit quality.

What Moves the Rate?

Pricing isn't arbitrary. Lenders — from major banks to private credit funds — are pricing based on the same core variables:

1. Loan-to-GRV (LVR)

The single biggest driver. A senior loan at 60% GRV will price better than one at 70% GRV. Every 5% of additional leverage increases risk materially in the lender's model. If you can bring more equity, or find a site at better relative value, this moves the rate.

2. Presale Coverage

Major bank presale requirements vary by institution and project size — there is no single rule. Some banks will lend at lower presale thresholds for smaller projects or repeat developers with an established relationship; others apply a fixed coverage ratio regardless of deal size. Non-bank lenders are generally more flexible — some will go to 50–60% debt coverage, and a few will consider zero presales for the right developer and location. The less presale coverage you have, the higher the rate and/or the lower the LVR you can expect from any lender.

3. Developer Track Record

A developer who has delivered comparable projects — same scale, same typology, same geography — will get better pricing than someone with a thinner record. Lenders price the person as much as the project.

4. Builder Quality and Contract Structure

Fixed-price contracts with established builders, with appropriate rise-and-fall provisions, reduce lender completion risk. Unfixed contracts, owner-builder arrangements, or builders without a proven track record add risk that gets priced in.

5. Location and Saleability

Lenders apply a mental haircut to projects in locations with thin buyer depth or long days-on-market history. ACT, inner Sydney, inner Melbourne, and established southeast Queensland corridors typically price better than regional or fringe locations.

6. Project Size and Lender Appetite

Very small projects (sub-$3M TDC) and very large projects (over $100M) both face pricing pressure — small projects are uneconomic for many lenders, large projects require syndication or hit concentration limits. The sweet spot for most lenders is $5M–$50M in total development cost.

The All-In Cost: What to Model

Rate alone doesn't tell the story. When you're stress-testing your feasibility, model the all-in finance cost — which includes:

  • Interest rate (on drawn balance, capitalised)

  • Line fee or non-utilisation fee (typically 0.5–1.5% p.a. on the facility limit)

  • Establishment / origination fee (typically 1.0–2.0% of facility)

  • Exit / discharge fee (some non-banks charge 0.5–1.0%)

  • Legal costs (both borrower and lender legal — budget $20,000–$40,000 for a standard deal)

  • Valuation and QS fees

For a typical $20M senior facility at 8.5% over an 18-month construction period, the all-in cost might look like:

  • Interest (on average 60% drawn): ~$1.5M

  • Line fee (1% p.a. on limit): $300K

  • Establishment (1.5%): $300K

  • Legal and due diligence: $50K

  • Total finance cost: ~$2.15M

This is why the finance line in your feasibility matters — and why structuring the facility properly (facility size, drawdown schedule, construction period) is worth spending time on.

How a Good Broker Moves the Rate

Rate is partially a function of which lender you're talking to, and partially a function of how well your deal is packaged and presented.

A well-structured credit submission — with a clear feasibility, builder contract, presale schedule, and developer profile — gives a lender confidence to price at the lower end of their range. A submission that raises questions, or forces a lender to chase information, gets conservative pricing or a pass.
