Commercial Construction Loan Western Sydney

By the Mortgagefy Team · Published 19 Oct 2026 · Last reviewed 19 Oct 2026

Buying raw commercial land and building your own premises is cheaper per m² than buying ready-made stock in most Western Sydney industrial corridors. The economics only work if the construction finance is structured properly from the start.

How it works

Commercial construction loans are progress-drawn against the build — you don't receive the whole loan upfront. Draws typically trigger at slab, frame, lock-up, fit-out and practical completion. The lender's QS or valuer inspects at each stage before releasing funds.

What's funded: land value plus hard construction cost (fixed-price contract strongly preferred). Soft costs (design, DA, legals) are usually buyer-funded. The lender's LVR cap applies to total project cost including land, usually 65-75% depending on project risk and borrower strength.

Fixed-price contracts with reputable builders are heavily preferred over cost-plus. Owner-builder arrangements are rare in commercial — lenders don't like the risk profile. If you're a licensed commercial builder building your own premises, that's a different conversation.

What commercial lenders actually look at

Contract type

Fixed-price with reputable commercial builder preferred. Cost-plus and owner-builder are much harder.

DA & approvals

Current, valid, no outstanding conditions. Full approval before loan commits is standard.

Borrower financials

Two years returns at today's position, demonstrated ability to service through build period.

Project risk

Site remediation needed, environmental overlays, unusual zoning — all add risk and tighten terms.

Ways to hold the property

Structure sits between you, your accountant and your lender — tax, asset protection and succession all matter. Four common patterns we see with Western Sydney owner-occupiers:

Personal name

Simplest to arrange. Interest can be deductible against rental income. Little asset protection from a trading-business perspective.

Company

Common for long-term holdings inside a corporate group. Flat company tax rate on rent; no CGT discount at the company level.

Trust (discretionary or unit)

Flexible for distributing rental income and separating property from trading-business risk. Lenders are comfortable with clean trust documentation.

SMSF — leased back at market rent

An SMSF can borrow (via a Limited Recourse Borrowing Arrangement) to buy premises that meet the ATO's "business real property" test and lease them to your business at arm's-length market rent. High-level only — a licensed SMSF specialist and your accountant must confirm your situation.

Frequently asked questions

65-75% of total project cost typical. Stronger borrowers and lower-risk projects access the top end. Specialised commercial builds tighter.

Yes — second security releases up more funds, subject to combined LVR cap.

No — each draw triggers after QS or valuer inspection confirms work completed and compliant. Build this into your cash-flow timing with the builder.

Strongly preferred. Cost-plus is possible but tighter LVR and more scrutiny. Owner-builder in commercial is rare.

Small commercial development (one or two tenancies) uses commercial construction finance. Larger multi-tenant commercial development uses specialist development finance — different pricing and structure.

Mixed-use (commercial + residential) is a different asset class and loan structure. Pure commercial doesn't permit occupation.

Interest-only during construction, capitalised in some structures. Switches to amortising P&I at practical completion.
