Could Your Block Help Fund Your Build?

October 3, 2026

Before we get into this week’s update, a little good news for the team. We’re proud to have been recognised in this year’s AFG awards, and I wanted to give a special thank you to our referral partners.

Every client you send our way comes with your trust attached. We never take that for granted, and this recognition is a lovely opportunity to acknowledge both our team’s hard work and your ongoing support.

Now, back to building. Once a client has bought their block, it doesn’t take long for the conversation to turn to floor plans, façades and a kitchen that somehow keeps getting bigger.

There’s also a useful finance question to ask: could the equity in that block help fund the build?

For clients who already own land, that equity may count towards their contribution to the project. This week, we look at how it works and what needs checking before the plans move off the page.

Can the Equity in Your Land Help Fund Your Build?

For buyers who already own their block, land equity can play an important role in financing a new home.

Equity is the difference between the land’s assessed value and the amount still owing on it. Depending on the lender’s assessment, it may contribute towards the construction project and reduce the additional cash the buyer needs to provide.

How it could work

Consider this simplified example:

ItemAmount
Assessed land value$400,000
Existing land loan$250,000
Building contract$350,000
Assumed lender valuation on completion$750,000

 

The buyer has $150,000 in land equity. Funding the existing land debt and the building contract would require $600,000 in total lending, before fees and other costs.
Against an accepted completed value of $750,000, that represents an 80% loan-to-value ratio.

The completed valuation is a separate assessment: it may differ from the combined land value and building cost. Lenders generally assess the proposed finished home using the building contract, plans and specifications.

What still needs to be checked?

Having equity is one part of the application. The lender will also consider:

  • The accepted property valuation and permitted loan-to-value ratio
  • The existing land debt and total funding required
  • The buyer’s income, expenses and ability to meet repayments
  • The building contract, additional costs and any required cash contribution

Cash may still be needed for the builder’s deposit, fees or items outside the approved finance. If the land loan is with a different lender, refinancing may also be required to arrange the construction funding.

A useful conversation for your next client meeting

For builder referrers, this is a good reason to reconnect with clients who own land and are still working towards their build.

Before they assume they need to save an entirely new deposit, reviewing their land equity, borrowing capacity, and building budget can clarify their options.

Have a client with a block and plans taking shape? Send them through, and we can work through the numbers together.

A proud moment for our team

We’re proud to see Mortgage Domayne recognised in the 2026 AFG Broker Awards. It’s a chance to celebrate our team and the work that happens behind the scenes to help clients move from their first conversation through to settlement.

To our referral partners and clients, thank you for being part of this achievement. Your trust and continued support mean a great deal to us, and we’re grateful for every opportunity to help bring your clients’ plans to life.
