Your Guide to Smarter Property Development Finance in Australia

The four disciplines of smarter development finance

Smarter development finance is a four-discipline practice, not a single decision. Each discipline addresses a different layer of finance risk:

Discipline 1: Capital stack optimisation

Each layer of the capital stack carries different cost and risk. Smarter capital stack optimisation finds the lowest blended cost of capital for a given project risk profile and developer equity availability.

The three optimisation principles:

• Maximise senior debt within bank policy. Each 5 percentage points of senior debt LVR displaces ~5 percent of mezzanine (or 10 percent if combined with equity reduction). Senior at 8% beats mezzanine at 14%
• Match mezzanine layer to actual gap. Over-sizing mezzanine increases blended cost; under-sizing creates equity stress and project execution risk
• Use preferred equity selectively. Preferred equity is expensive (15 to 25 percent return) but preserves senior debt headroom and avoids high-rate mezzanine when developer equity is constrained

Discipline 2: Early lender engagement

Senior lenders should be engaged 8 to 12 months before construction commencement. The phased engagement allows:

• Months 8 to 6 before construction: feasibility study refinement, lender soundings, indicative term sheets from 2 to 3 senior lenders
• Months 6 to 4: lead lender selection, formal credit submission, valuer instructed
• Months 4 to 2: credit approval, settlement documentation, conditions precedent management
• Months 2 to 0: facility settlement, builder appointment, council approvals finalised, first drawdown ready

Discipline 3: Pre-sales velocity management

Pre-sales velocity is how quickly contracted pre-sales accumulate from launch to construction commencement. Lenders care because:

• Senior debt facilities have conditions precedent timeframes (typically 12 months from term sheet) within which the required debt coverage ratio must be achieved
• Pricing tiers in standard senior debt facilities are commonly tied to pre-sales achievement (e.g., margin step-down at 80% coverage)
• Slow pre-sales velocity signals weak product-market fit, which affects credit confidence on the broader feasibility

The three velocity practices that consistently work:

• Build a pre-launch registered buyer database 6 to 12 months ahead of launch (Billbergia’s approach across active projects)
• Stage releases strategically (smaller initial releases generate competitive tension)
• Use direct-from-developer channels rather than third-party agents to maintain pricing discipline

Discipline 4: QS-led cost certainty

A registered quantity surveyor (RICS or AIQS qualified) is the gatekeeper of cost certainty across the project. Two functions matter most for finance optimisation:

Pre-construction cost plan

The QS-prepared cost plan is the foundation document for senior debt credit submission. A robust cost plan with current market-rate trade pricing, contingency provision (typically 5 to 8 percent), and stress-tested escalation assumptions accelerates credit approval and reduces the developer-equity contribution required.

Drawdown certification

During construction, the QS issues monthly drawdown certificates verifying that claimed works have been completed to specification. Strong drawdown discipline protects the lender, but it also protects the developer from cost overrun creep by surfacing issues monthly rather than at completion.

Lender relationship practices that survive credit cycles

Australian bank credit policy tightens through downturns and through APRA macroprudential interventions. Developers who survive credit cycle tightening typically share three practices:

• Consistent senior lender across multiple projects: relationships built over 3 to 5 projects survive policy changes better than transactional relationships
• Quarterly portfolio updates to credit teams: even when not actively borrowing, keeps the credit team informed and reduces information friction at next facility application
• Maintain non-bank backup lender relationships: even when not needed; preserves optionality if bank credit tightens

The integrated developer-builder model at Billbergia strengthens lender confidence further because internal QS, programme and cost control oversight reduces the information asymmetry that lenders typically face. The iCIRT 4.5-Gold Star rating (2025) provides independent verification used in credit assessment.
