How much deposit do you need for a construction loan?

Construction loan deposits are typically based on the total project cost — including land and build.

Common ranges include:

  • 5–10% deposit – possible in some scenarios, subject to lender policy
  • 10–20% deposit – more flexibility and broader lender choice
  • 20%+ deposit – avoids lenders mortgage insurance (LMI) in most cases

The exact requirement depends on your financial position, the project and the lender.

What counts as a deposit for construction?

Construction deposits can come from multiple sources.

Common options include:

  • savings held over time
  • equity from existing property
  • land value (if you already own the land)
  • gifted funds (subject to lender policy)

In many cases, the land itself forms a significant part of your deposit.

Using land as your deposit

If you already own the land, its value can be used as equity.

This typically involves:

  • obtaining a valuation of the land
  • comparing the land value to the total project cost
  • using that equity to reduce or eliminate the need for cash deposit

This is one of the most common structures for construction lending.

How lenders assess construction deposits

Lenders assess deposits alongside the full build scenario.

They will typically consider:

  • total project cost (land + construction)
  • loan-to-value ratio (LVR)
  • source and structure of the deposit
  • borrowing capacity and servicing position
  • building contract and builder credentials
  • contingency or cost buffers

Different lenders take different approaches, particularly for higher LVR builds.

Common challenges with construction deposits

Construction deposits can create issues if not structured correctly.

Common problems include:

  • underestimating total project costs
  • relying on equity without confirming usable value
  • insufficient buffers for variations
  • choosing lenders with restrictive construction policies
  • assuming land value alone will always be sufficient
  • not aligning deposit with borrowing capacity

These issues can delay approval or limit your options.

How we structure construction deposits at Evolve

We focus on aligning your deposit with the full build strategy.

This includes:

  • confirming total project costs upfront
  • assessing cash vs equity contributions
  • structuring land equity where applicable
  • identifying lenders suited to your scenario
  • ensuring sufficient buffers for variations
  • aligning deposit structure with borrowing capacity
  • positioning the application for smooth approval

The objective is to ensure your deposit supports the build — not creates friction.

Speak with a broker before finalising your deposit

Construction lending requires more upfront clarity than standard loans.

Before proceeding, it’s worth understanding:

  • how much deposit you actually need
  • whether your land or equity can be used
  • how lenders will assess your full project
  • what buffers are required
  • how to avoid delays during approval

A well-structured deposit keeps your build moving. A poorly structured one can slow it down.
