One Doc Home Loan Between Developments (2026)
The gap between completing one development and starting the next is when most developers lose home loan eligibility under full-doc assessment. A One Doc home loan uses an accountant's letter to verify income capacity rather than requiring two years of consecutive tax returns — which means the inter-project gap doesn't disqualify you if the letter is structured correctly.
Quick Answer
A One Doc home loan lets property developers qualify for residential lending during the gap between projects by using an accountant-certified income letter instead of sequential tax returns that reflect the lumpy revenue cycle of development work.
Why Does the Gap Between Projects Kill a Home Loan Application?
Full-doc lenders assess income by averaging the last two financial years of tax returns. For a developer who completed a project in FY24 and hasn't yet settled or drawn on their next project in FY25, the most recent tax return shows reduced or zero development income — even if the next project is fully approved and funded. The lender reads the gap as a decline in earning capacity rather than a normal business cycle.
This is where most developer home loan applications stall. The loan-to-value ratio might be conservative, the deposit might be strong, and the applicant might have millions in project equity — but the income line on the most recent return doesn't clear the servicing calculator. A non-bank lender using One Doc assessment reads the same borrower differently because it relies on an accountant's forward-looking certification of income capacity rather than backward-looking tax returns.
The distinction matters most for developers who operate through a trust or company structure, where retained earnings sit in the entity rather than flowing through to a personal tax return. The ATO's guidance on trust income distribution confirms that distributable income is an entity-level decision — and the timing of that distribution rarely aligns with a mortgage application timeline.
What Your Accountant Needs to Certify (and Where They Push Back)
The accountant's letter is the single document that determines whether a One Doc application succeeds or fails. Non-bank lenders require the letter to certify the applicant's current annual income and confirm the borrower is self-employed and GST-registered. For a developer between projects, the pushback usually comes from the accountant — not the lender.
Common Objection
"I can't sign a letter certifying income when there's no active project generating revenue right now."
This is the most common accountant objection — and it's based on a misunderstanding of what the letter certifies. The letter doesn't certify current cash receipts. It certifies the borrower's capacity to earn at a stated level based on their track record, existing pipeline, and business structure. A developer who completed three projects in five years and has development approval on their next site has demonstrable income capacity — the inter-project gap doesn't erase that history. The accountant is certifying capacity, not cash-in-bank.
Common Objection
"The income is too lumpy — there's a $400,000 profit one year and $30,000 the next. I can't average that."
Non-bank lenders expect lumpy developer income. The letter should state the annualised average over a reasonable period — typically three to five years — rather than the most recent single year. If three projects over five years generated a combined profit (illustrative, varies by project scope and market), the annualised figure is what the lender uses for servicing. The accountant smooths the income across the development cycle, not within a single financial year. Your broker structures the letter wording before the accountant drafts it — the format matters as much as the number.
The accountant's comfort level usually increases once they understand that the lender's credit team reads the letter alongside bank statements, the applicant's asset position, and the development track record — not in isolation. See the full One Doc guide for property developers for the complete certification framework.
How to Structure the Application During a Project Gap
Timing the application correctly is the difference between a clean approval and a conditional decline. The strongest position is when the previous project has settled (cash is visible in the bank), the next project has DA approval and finance in place, and the accountant can point to both as evidence of ongoing capacity.
The completed project's settlement funds should be sitting in a business or personal account for at least 30 days before lodging the home loan application. Lenders want to see the cash, not a settlement statement alone.
A summary of completed projects over the last three to five years with approximate project values, timelines, and profit outcomes. This doesn't need to be audited — a schedule prepared by the accountant or the developer is sufficient as supporting evidence alongside the income letter.
The broker provides the exact wording template the non-bank lender requires. The accountant fills in the income figure and signs. Deviations from the expected format — adding caveats, disclaimers, or conditional language — are the number one reason One Doc applications get sent back for rework.
A developer mid-build has drawdowns outstanding and construction debt on the balance sheet. Lodging the home loan after the previous project has settled and before the next project's construction finance is drawn gives the cleanest servicing picture — lower existing commitments, higher visible cash reserves.

If you're currently in the gap between projects, check your eligibility before the next project's debt hits your servicing.
When the Between-Developments Window Is Strongest (and When It Gets Tricky)
Not every inter-project gap produces a clean One Doc opportunity. The strength of the application depends on the size of the gap, what's visible in the bank, and how the accountant frames the income letter. Here's where the dividing line sits.
Stronger Fit
- Previous project settled within last 6 months — cash visible
- Next project has DA and finance approved
- Three or more completed projects in the last 5 years
- Accountant willing to certify annualised income
- No outstanding construction debt on current balance sheet
Gets Tricky
- Previous project settled 12+ months ago — proceeds spent down
- Next project is speculative with no DA or funding
- Only one prior project — limited track record
- Accountant adds heavy caveats to the income letter
- Existing second mortgage or caveat still registered

How Developer Equity and LVR Affect the One Doc Approval
Developers between projects often have significant equity tied up in completed stock, land holdings, or retained earnings within a company or trust. Non-bank lenders assess the One Doc application against the home loan LVR in isolation — but they note the broader asset position as supporting context.
A developer with a strong equity position applying at 70% LVR or below will typically receive a faster credit decision than a developer at 80% LVR with the same income certification. The equity buffer signals to the credit team that even if income fluctuates, the borrower has capacity to service through project gaps.
Where developers run into trouble is when project equity is locked in unsettled stock or land that hasn't been rezoned. These assets appear on the balance sheet but aren't liquid — and non-bank credit teams treat illiquid developer equity differently to cash or residential property. If your equity is tied up in unsettled lots, talk to your broker about structuring the equity release before lodging the home loan application.
For developers who also hold commercial property, the rental income from those holdings can supplement the accountant's income letter — creating a dual-income stream that strengthens servicing even when development income is paused between projects. The commercial property loan rates guide covers how existing commercial debt interacts with residential servicing calculations.
The gap between developments is a normal part of the project cycle — but full-doc lenders treat it as an income disruption. A One Doc home loan bypasses the tax return problem by relying on an accountant's certification of annualised income capacity across your development track record. The strongest applications lodge during the window when settlement proceeds are visible and before the next project's construction debt is drawn. Your broker structures the letter wording, your accountant signs it, and the non-bank credit team reads the full picture — not just the most recent return.
Key takeaway: Time the application to the gap, not the project. That's when your servicing picture is cleanest and your One Doc case is strongest.Frequently Asked Questions
A low recent tax return does not disqualify you from a One Doc home loan. Non-bank lenders assess income using an accountant's certification of your annualised earning capacity — typically averaged across three to five years of development activity — rather than relying on the most recent single year. The inter-project gap that produces a low return is a known pattern in development income, and specialist non-bank credit teams assess it accordingly. Your broker provides the letter template; your accountant certifies the figure.
The accountant's letter must state the applicant's name, ABN, the nature of their business (property development), and their current annual income figure. The letter certifies that the stated income is a reasonable reflection of the borrower's earning capacity based on their trading history. It must be on the accountant's letterhead, signed, and dated within 90 days of the application. The broker supplies the exact wording template — deviations, especially added disclaimers or conditional language, will trigger a rework request from the credit team. See the developer One Doc guide for the full letter structure.
Before — specifically, after the previous project has settled and before the next project's construction drawdowns begin. This window gives you the cleanest servicing position: settlement proceeds are visible in the bank, and no outstanding development finance sits on the balance sheet reducing your borrowing capacity. Once construction debt is drawn on the next project, it appears as existing commitments — and the home loan servicing calculator treats it as an ongoing liability even though it's a short-term facility.
Non-bank lenders routinely accept income from trust and company structures under One Doc assessment. The accountant's letter certifies the income attributed to the borrower from the entity — whether that's a distribution from a discretionary trust, a director's salary from a Pty Ltd, or a combination of both. The key requirement is that the accountant confirms the borrower has access to the stated income level on an ongoing basis. Entity structures are standard in property development, and specialist non-bank lenders are built to assess them. The property lending hub covers how different entity structures interact with lending assessment.
Most non-bank lenders cap One Doc home loans at 80% LVR for owner-occupied purchases and 70–75% LVR for investment properties, though exact limits vary by lender and individual risk profile. Developers with strong track records, clean bank statements, and a solid accountant letter may access the upper end of these ranges. Applying at 70% LVR or below typically produces faster approvals and fewer conditions because the equity buffer gives the credit team more comfort with the income certification. See private lending for property transactions for how LVR interacts with non-bank assessment across different property types.
