One of the first questions I get from clients buying a commercial property isn’t about rates, or even about how much they can borrow. It’s quieter than that: “What paperwork am I actually going to need?” The honest answer is that it depends on which of two assessment paths your deal goes down, and most people have never heard the terms for either.
Lease-doc and full-doc describe how a lender proves your loan can be repaid. The path you land on shapes your documentation, your maximum LVR, and sometimes whether the deal gets approved at all. It isn’t a separate product you apply for. It’s the lens a lender uses to weigh up serviceability, and it applies right across commercial property, from a tenanted warehouse to an owner-occupied industrial unit.
In more than 15 years arranging commercial finance, I’ve watched this one distinction decide whether a deal runs smoothly or drags on for months. Knowing which path fits your situation before you apply is what separates a clean approval from endless back-and-forth with the wrong lender.
What lease-doc and full-doc actually mean
In commercial property finance, lease-doc and full-doc describe how a lender proves the income story behind your loan. They aren’t marketing labels. They’re also not interchangeable with the residential terms people sometimes confuse them with. Each one changes the documents you’ll need, the way a lender works out whether you can service the debt, and how conservative your final structure ends up being.
Lease-doc means the lender leans heavily on the property’s lease income to assess serviceability. If you’re buying a property with a solid tenant and a registered lease, the rent that tenant pays does most of the work in proving the loan is affordable. The lease is the centre of the file.
Full-doc means the lender uses your own financials as the primary evidence: tax returns, financial statements, BAS, and management accounts. The property and any lease still count as security, but the question shifts. Now the lender is asking “can this borrower service this debt,” not “can this rent cover this loan.” In practice, full-doc sits much closer to a business loan than to a home loan, even though the security is bricks and mortar. That single distinction drives almost everything else that follows.
If you’re not sure which path your situation points to, it helps to first understand how commercial property loans work more broadly, then come back to this decision with that context.
Lease-doc vs full-doc: the key differences at a glance
Here’s how the two paths compare across the factors that matter most. Terminology varies between lenders, so treat this as the shape of the decision rather than a fixed rulebook. What stays constant is the underlying logic: which evidence the lender will accept, and how cautious they’ll be with it.
| Factor | Lease-doc | Full-doc |
|---|---|---|
| Primary income proof | Registered lease plus evidence the rent is being paid | Borrower and business financials (tax returns, BAS, statements) |
| Typical use case | Investment property with a reliable tenant | Owner-occupier, vacant property, or complex income |
| Serviceability lens | Property income and lease strength drive the assessment | Business and borrower cash flow drive the assessment |
| Documentation load | Lighter on financials, but the lease pack must be watertight | Heavier financial pack plus lease and security documents |
| Typical maximum LVR | Often more conservative, commonly around 70% for investment assets | Up to 80% for owner-occupiers with strong financials |
| Where it tightens | Short lease term or weak tenant leads to rent discounts and lower LVR | Weak financials sink servicing regardless of how good the lease looks |
The figures above are general guidance only and shift with the lender, the asset, and the current lending environment. You can see indicative current ranges on our commercial property interest rates page.
What lenders look for on a lease-doc deal
Because the income comes from the lease, a lease-doc lender cares about two things above all else: how certain the lease is, and how sustainable the rent is. A lease-doc deal can be genuinely strong. But only if the lease is what I’d call credit-ready.
I’ve seen perfectly good purchases stall because the lease was still in draft, or because the rent on paper didn’t match what was actually landing in the account. The detail matters more than people expect.
On the lease itself, lenders want a registered lease rather than heads of agreement or draft terms, a sensible expiry profile, and clean mechanics around options, rent reviews and make-good clauses. Weighted average lease expiry sits at the heart of it. A short remaining term reads as higher risk, because the income could run out before the loan does. If you want to go deeper on why expiry profile carries so much weight, I’ve written separately about why WALE is the metric that matters.
On the tenant, it comes down to financial strength, the industry they operate in, and concentration risk. A single tenant occupying the whole building is riskier than a diversified income stream, because one departure empties the property. Lenders also want proof the rent is genuinely being paid, usually through a ledger or bank statements, and they’ll scrutinise any history of arrears or disputes closely.
All of this feeds straight into how the lender calculates serviceability and values the property. Here’s the part clients find counterintuitive: a short lease or a weak tenant can reduce the income a lender will count, even when the headline rent looks healthy. The rent figure on the lease isn’t always the rent figure the bank uses.
When full-doc becomes essential
Full-doc is the path when the property’s income alone doesn’t give the lender enough certainty, or when the deal is really a business cash flow loan that happens to be secured by property. A handful of scenarios tell me straight away that we’re looking at a full-doc assessment.
The most common is an owner-occupied property, where your own business pays the loan rather than an external tenant. There’s no arms-length rent to lean on, so the lender looks straight through to your business financials. A vacant or short-leased property lands in the same place: the lease risk is too high to rely on rent alone. A related-party tenancy, where your own entity leases the building from you, usually pushes the assessment toward full-doc as well, because the lender won’t treat that rent as arms-length and often discounts it. And any cash-out or restructure tends to invite deeper scrutiny of your capacity and the purpose of the funds.
On a full-doc deal, the quality of your financials can make or break the approval. Being organised genuinely pays off here.
If you’re weighing up whether to buy your own premises rather than keep renting, it’s worth understanding early that owner-occupier lending leans on your financials, not a tenant’s rent. Our guide on whether to buy or rent commercial property walks through that decision in more detail.
How this connects to LVR, serviceability and your deposit
The lease-doc versus full-doc question never sits on its own. It flows directly into how much you can borrow and how much deposit you’ll need.
Because a lease-doc deal carries income risk tied to a single lease, lenders often cap the LVR more conservatively, which means a larger deposit. A full-doc owner-occupier with strong financials can frequently borrow at a higher LVR, because the lender sees a fuller picture of their capacity. The documentation path and the deposit you need are two sides of the same coin.
It also shapes how the lender stress-tests the loan. On a lease-doc deal, the lender checks whether the net rent can cover the repayments with a buffer built in. On full-doc, it checks whether your broader cash flow can. Either way, the safest move is to run your own numbers before you sit down with a lender, so nothing comes as a surprise. Our borrowing capacity calculator is a good place to get a feel for the range you’re working within (and better understand Debt Service Coverage Ratio or DSCR).
Common pitfalls and how to avoid them
Most deals I see get stuck don’t fail because the borrower wasn’t good enough. They stall on avoidable documentation problems. A few come up again and again:
- Draft leases or missing variations. Lenders want executed, registered documents with a clear rent schedule. A lender can’t assess a lease that’s still being negotiated, and waiting for it to finalise mid-application burns time you didn’t budget for.
- Confusing outgoings. If it’s unclear which outgoings the tenant covers and which the landlord absorbs, the lender treats the net income conservatively, which can quietly lower the amount you can borrow.
- Undisclosed incentives. Rent-free periods and fit-out contributions matter, because the lender cares about effective rent, not just the face rent written into the lease.
- A short lease at high leverage. Borrowing at a high LVR against a property with a short remaining lease term pressures the serviceability assessment and the valuation at the same time.
- Assuming lease-doc means fast. Lease-doc can involve fewer financials, but the lease pack and the valuation still take time. It’s lighter, not instant.
Almost all of these come down to preparation. Knowing which path your deal is on, and what that path demands, is most of the battle.
Common questions about lease-doc and full-doc commercial loans
What is a lease-doc commercial loan?
A lease-doc commercial loan is one where the lender assesses serviceability primarily on the property’s lease income rather than your detailed business financials. You’ll still need documents, including the registered lease, evidence the rent is being paid, identification, and a summary of your assets and liabilities. The real difference is that the lease, rather than your tax returns, drives the income assessment.
Is lease-doc the same as low-doc?
No, and it’s a common mix-up I see all the time. Low-doc generally refers to limited income verification for the borrower. Lease-doc is specific to leased commercial property and is still document-heavy in its own way. The lenders we work with want a strong, registered lease, solid rent evidence, and comfort around the tenant and the lease terms. The reduced paperwork sits on your personal financials, not on the property.
Do I still need financials for a lease-doc loan?
Usually fewer than a full-doc application, but rarely none. Many of the lenders we work with still ask for an assets and liabilities position, bank statements, and sometimes financial statements or BAS, simply to understand the broader risk. How much they want depends on the lender’s policy and how you’ve shaped the deal.
What is a full-doc commercial loan?
A full-doc commercial loan relies on your borrower financials, including tax returns, financial statements, BAS, and management accounts, alongside the property and any lease as security. It’s the standard path for our owner-occupier clients, and for any deal where the lease income alone doesn’t give the lender enough certainty.
Does the maximum LVR differ between lease-doc and full-doc?
Yes it usually does. Lease-doc deals can attract a more conservative LVR where the income carries more risk, while a strong owner-occupier on full-doc may borrow at a higher LVR because the lender sees a complete view of capacity. That said, the final LVR depends heavily on the asset type, the valuation, and the individual lender’s appetite, so the documentation path is only one part of the picture.
What happens if my tenant is related to me?
We find our lenders usually treat a related-party lease more conservatively, because they don’t consider the rent arms-length. They may discount the rent, ask for stronger financial verification, or move the assessment toward full-doc and global servicing, depending on how you’ve set up the structure.
Can an SMSF use a lease-doc style assessment?
Some of our SMSF lenders do lean heavily on lease income, but SMSF lending policy is lender-specific and the documentation requirements can be stricter. If your fund is buying a property with a tenant in place, confirm the borrowing arrangement and lender policy early, and make sure the lease terms and rent evidence are robust before you go too far.
How do I work out which path suits my deal?
We advise our clients to start by modelling their serviceability and leverage under conservative assumptions, then look honestly at what documentation they can provide and how strong the lease is. From there it becomes much clearer. Because lender policies differ so much, this is exactly the kind of thing a commercial finance broker can run across a panel of lenders to find the best fit, rather than you guessing and hoping the first bank says yes.
Getting the right assessment path for your purchase
The choice between lease-doc and full-doc isn’t really a choice you should make in isolation. The shape of your deal decides it: whether there’s a tenant, how strong the lease is, whether you’re occupying the property yourself, and how your financials look.
Understanding it ahead of time pays off in a simple way. You walk into the process knowing what evidence you’ll need and which lenders are likely to suit, instead of finding out the hard way after a decline. With access to 60+ lenders, my job here is to match the way your deal is best assessed to the lenders whose policies actually fit it.
