What are duplex and townhouse development loans?

These loans are designed to fund multi-dwelling residential projects, typically including:

  • duplex builds (2 dwellings on one title or subdivision)
  • townhouse developments (3–6 dwellings)
  • small-scale residential developments with repeatable design

They sit between residential lending and full commercial development finance, requiring a structured approach to funding.

How duplex and townhouse development finance works

Funding is structured around the project lifecycle.

This typically involves:

  • funding land acquisition (if required)
  • funding construction costs in stages
  • assessing total development cost (TDC)
  • releasing funds based on progress
  • repaying the loan through sale or refinance

The structure needs to align with both the build timeline and the intended exit strategy.

How lenders assess duplex and townhouse projects

Lenders assess these projects based on both the borrower and the deal.

They will typically consider:

  • total development cost (TDC)
  • end value (gross realisation value – GRV)
  • loan-to-cost (LTC) and loan-to-value (LVR)
  • developer experience or project support
  • builder credentials and fixed-price contracts
  • location and market demand
  • exit strategy (sale or hold)

Different lenders have varying appetite depending on project size and complexity.

Feasibility and project viability

A strong feasibility is critical for approval.

Lenders will expect:

  • realistic build costs and timelines
  • conservative end values
  • appropriate contingency allowances
  • acceptable project margins
  • a clear and achievable exit plan

Even small errors in feasibility can affect funding outcomes.

Common challenges with duplex and townhouse developments

These projects can appear straightforward — but still carry risk.

Common issues include:

  • underestimating total development costs
  • overestimating end values
  • insufficient contingency buffers
  • choosing lenders without development experience
  • poor structuring of equity or deposit
  • unclear or unrealistic exit strategies
  • lack of alignment between loan structure and project timeline

These challenges can delay or prevent approval if not addressed early.

How we structure duplex and townhouse loans at Evolve

We focus on aligning the project with the right funding structure.

This includes:

  • reviewing feasibility and project assumptions
  • structuring funding based on TDC and GRV
  • identifying lenders suited to this type of development
  • aligning loan drawdowns with construction stages
  • ensuring appropriate buffers and contingencies
  • positioning your experience and support team
  • mapping a clear exit strategy

The objective is to structure a deal that works for both the lender and the project.

Speak with a broker before committing to a project

Development finance should be structured before you commit to land or build.

Before proceeding, it’s worth understanding:

  • whether your project is financeable
  • how lenders will assess feasibility
  • what deposit or equity is required
  • how the loan will be structured
  • what risks exist around timing, cost and valuation

A well-structured project gets funded. A poorly structured one often doesn’t.
