One Doc Home Loan When Your Deposit Is in a Development

You are mid-build, your cash and equity are tied up in an active development, and you want to buy or refinance a home. A One Doc home loan can work here, but the servicing read while the build is live is different from a standard application. Here is how a lender reads it, and how to sequence the exit.

Quick Answer

Yes, you can often put equity from an active development toward a One Doc home loan, but a lender assesses the servicing read while the build is live, not just the equity on paper. The cleaner your exit, the smoother the path.

Can development equity be your home loan deposit?

Yes, equity in an active development can count toward a One Doc home loan deposit, as long as the lender can see a clear servicing position and a credible exit. The catch is timing: when your cash and equity are tied up in an active development, that equity is real but not yet liquid.

Picture a self-employed owner-developer two-thirds of the way through a project. Most of the deposit they would normally put toward a home is sitting in the development, and it will not be free until the stock sells. A second mortgage or private lending against existing security can free part of it sooner, but where that is not an option a One Doc home loan is built for exactly this gap, because it assesses you on a single income document rather than a full tax-return history.

How a One Doc lender reads mid-project equity

A One Doc lender treats mid-project equity as a real but partly locked asset, so the file turns on servicing and exit rather than the equity figure alone. From the broker side of the desk, the number that matters is not the equity on paper, it is whether the loan services while the build is live.

The income side usually rests on an accountant letter or BAS as the income document, and the servicing read while the build is live is what a lender weighs hardest. A clean file and a messy file split along predictable lines.

What makes the file work

  • A clear accountant letter or recent BAS a lender can rely on
  • The build on schedule against a dated feasibility
  • A defined sell-down or refinance exit, evidenced not promised
  • Deposit or equity commonly around 20 percent, varies by lender
  • Clean conduct on existing facilities

What makes it stall

  • No income document a lender can lean on
  • The build behind schedule with no revised feasibility
  • Equity that only exists on an optimistic valuation
  • No exit evidenced before settlement
  • The development and the home loan competing for the same cash

A worked case: buying a home mid-build

The clearest way to see how this reads is to walk a single file from start to settlement.

Case scenario, owner-developer mid-project A self-employed builder is two-thirds through a three-dwelling development, with most of her cash and equity committed to the build. She wants to secure a home before the project completes, but a bank wants two years of returns she cannot show cleanly mid-project. A One Doc home loan assessed her on an accountant letter, a current valuation of the development, and a dated plan to repay from the sell-down. The loan funded as a holding position, with the exit mapped to the project completion. For the post-completion version of this path, see One Doc home loan after your first development.

Sequencing the exit: refinance once the development sells

The exit is what turns a One Doc home loan from a holding position into a long-term one, and most owner-developers refinance to a bank rate after the development sells. Where I see these files clear cleanly, the exit was evidenced before settlement, not promised after it.

That means a dated sell-down plan, a realistic valuation, and a documented route back to mainstream income once the stock settles. Compared with a standard bank home loan, the One Doc rate is higher while the build is live, which is the trade-off for the lighter paperwork; you can compare standard home loan features on ASIC's MoneySmart guide to home loans. Owners who sold on deferred terms face a related sequencing question, covered in One Doc home loans after a vendor-terms sale.

A One Doc home loan can carry you while your deposit and equity are tied up in an active development, but the file turns on the servicing read and a credible exit, not the equity figure on its own. Line up an income document a lender can rely on, keep the build on a dated feasibility, and evidence the sell-down or refinance before settlement. Done in that order, the home loan becomes a holding position you refinance to a bank rate once the development sells.

Key takeaway: with a One Doc home loan, the equity gets you in the door, but the servicing read and a clean exit are what get the file approved.

Frequently Asked Questions

Using equity from a development as the deposit for a One Doc home loan is possible, provided the lender can verify your servicing position and a credible exit. Mid-project equity counts as a real but partly locked asset, so the assessment leans on your income document and the project feasibility rather than the equity figure alone. For self-employed borrowers juggling several facilities, the business owners finance hub shows how these pieces fit, and linking the development finance and the home loan into one coherent story is what gets it across the line.

A One Doc home loan typically relies on a single income document, commonly an accountant letter or recent BAS, rather than a full set of tax returns. That single document has to stand up on its own, so it needs to state your income position clearly and match your business activity. The lighter paperwork is the point of the product, but the servicing read behind it is still real.

A One Doc home loan usually carries a higher rate than a standard bank home loan, which is the trade-off for assessing you on one income document while your equity is locked in a build. That gap is why most owner-developers treat it as a holding position and plan to refinance to a bank rate once the development sells. Pricing the exit into the plan from the start keeps the higher rate temporary.

Refinancing a One Doc home loan after your development sells is the standard exit, and lenders expect to see it mapped out before settlement. Once the sell-down completes and your income is documented in the usual way, you can move to a mainstream home loan at a sharper rate. The cleaner the exit you evidence up front, the easier that refinance is later.

Deposit requirements for a One Doc home loan are commonly around 20 percent deposit or equity, though this varies by lender and by how your security is structured. When that equity sits inside an active development, the lender looks at how accessible it really is, not just the headline valuation. Pairing it with a clear servicing position is what makes a lender comfortable.
