Quick answer

A low doc second mortgage or caveat loan is a private business loan secured behind an existing mortgage, where the decision rests on the property's equity and a documented exit rather than tax returns and financial statements. You still need photo ID for every owner, proof of ownership and entity details, a current statement for the first mortgage, the business purpose and evidence of how the loan will be repaid. Amounts run from $20k to $5m.

Key points

  • Low doc means the decision rests on equity and the exit, not years of financial statements
  • Still needed: ID, ownership, your first mortgage statement, the purpose and proof of the exit
  • Behind your bank's loan, so its arrears, terms and payout figure matter more than in a first mortgage
  • A low doc caveat loan can later convert to a registered second mortgage
Amounts
$20k – $5m
Structures

“Low doc” gets used loosely. For some lenders it means an accountant’s declaration in place of tax returns. For others it means no paperwork at all, which usually means a very high price or a lender you shouldn’t trust. Here it means something precise: the loan is decided on the property’s equity and a documented exit, so the paperwork you provide is about those two things, not about proving three years of income.

This page is about low doc lending behind an existing mortgage: second mortgages and caveat loans. If the property is debt-free or you’re refinancing the whole debt, the low doc first mortgage page is the better starting point.

What does “low doc” mean for a second mortgage or caveat loan?

A bank asks: can this business service the debt for years? That question needs tax returns, financial statements and forecasts. A short-term private lender behind your bank asks two different questions: is there enough equity after the first mortgage, and how exactly will this loan be repaid within its term? Those questions need different documents, and fewer of them.

Key terms

  • Low doc: assessed without full financial statements and tax returns at the centre of the decision.
  • Second mortgage: a registered mortgage that ranks behind the existing first mortgage.
  • Caveat loan: a loan supported by a caveat lodged on the title, which stops other dealings being registered without notice to the lender.
  • First mortgagee: the lender already registered first on the title, usually your bank. See first mortgagee.
  • Exit: the event that repays the loan.

What’s still needed: the short list

Item Why it’s needed What counts
Photo ID for every owner and guarantor Identity must be verified before anyone signs Driver licence, passport
ABN or ACN, trust deed if relevant Confirms who borrows and who can give security ABN Lookup record, company extract, deed and variations
Property details Shows what secures the loan Address and title details
First mortgage statement Shows the debt ahead and whether it’s up to date Recent statement or payout letter
Business purpose Confirms it’s a business loan A line or two, plus the bill or contract
Exit evidence Shows how the loan is repaid See the ladder below

Identity is the one area where “low” never applies. Under ARNECC’s rules for electronic conveyancing, subscribers must keep complying with verification of identity requirements, and lenders take that seriously, because a forged signature on a mortgage is a problem for everyone.

What can stand in for tax returns? The exit evidence ladder

The less you can show about income, the more the exit has to carry. Exit evidence ranks roughly like this:

Strength Evidence Example
Strongest A signed contract with a date Sale contract on another property; unconditional refinance approval
Strong A contract with payment terms A head contract with a progress-payment schedule
Good Issued invoices to reliable customers Invoices from established customers with a payment history
Supportive An accountant’s letter or forecast Cash forecast showing receipts covering the loan
Not an exit Hope “Sales should improve next quarter”

Plenty of low doc borrowers have strong exits. A builder with a signed sale contract on a completed townhouse doesn’t need three years of returns to show the loan will be repaid on settlement day.

Why does the first mortgage matter more in a low doc loan?

Behind a bank, the second lender’s position depends on the first. So the file needs to answer:

  • Is the first mortgage up to date? Arrears on the bank loan are the biggest single risk. Clearing them at settlement is often part of the deal.
  • What’s the payout figure? It sets the equity that’s really available.
  • Does the bank’s mortgage restrict further dealings? Some first mortgages require the existing lender’s permission before a second mortgage is registered. The Queensland Government’s own home loan terms, for example, require borrowers to get its permission first. Your solicitor can check your bank’s terms; see first mortgagee consent.

Caveat or registered second: which low doc structure fits?

Low doc caveat loan Low doc registered second mortgage
What goes on title A caveat A registered mortgage behind the bank
First lender’s consent Not always required to lodge; check the bank’s terms May be required
Speed Fastest Fast
Typical term Short Short, can run a little longer
State time limits Some states limit how long a caveat lasts unchallenged Not applicable
Can it change later? Can convert to a registered second mortgage Stays as is until discharge

NSW Land Registry Services describes a caveat as stopping registration of other dealings; if the owner applies, it lapses 21 days after a lapsing notice is served unless the caveator gets a court order. That’s why caveats suit short needs. For the step from one to the other, read converting a caveat to a second mortgage, and the caveat loans pillar for the full picture.

How do ATO debt and a damaged credit file fit in?

Low doc and messy tax affairs often travel together. Two things worth knowing:

  • The ATO can report business tax debts to credit reporting bureaus where at least $100,000 is overdue by more than 90 days and the business isn’t actively engaging, for example by keeping to a payment plan. See ATO debt on your credit file.
  • Here, bad credit, ATO debt and past defaults are considered case by case. Equity and exit matter most.

Common uses: clearing an ATO debt in one step (pay ATO debt with property equity) or dealing with a plan that’s collapsed (ATO payment plan defaulted). The second mortgage with bad credit or ATO debt page goes deeper.

What usually trips up a low doc application?

Short files fail for short reasons. The ones that come up most:

  • Undisclosed debts on the property. A second caveat or a private loan the borrower forgot to mention changes the equity overnight. List everything registered on the title.
  • A co-owner who isn’t on board. Every registered owner must sign, including a spouse or business partner who holds a share.
  • An exit that depends on the loan itself. “We’ll use the money to win work that repays it” is circular unless the work is already contracted.
  • Trust paperwork gaps. A trustee can only give security if the deed allows it, so missing variations stall otherwise simple deals.
  • Statements that don’t match the story. If the first mortgage is in arrears, say so upfront; it’s far easier to solve at the start than to explain later.

How does it work?

  1. Enquire in about 60 seconds. No credit check at this stage.
  2. Specialist call to confirm the equity, the first mortgage position and the exit.
  3. Document request, limited to the short list above.
  4. Letter of Offer: amount, term, interest option and assessment fee.
  5. Sign and verify ID, with your solicitor reviewing.
  6. Settlement: funds released, caveat lodged or second mortgage registered.

Who suits a low doc second mortgage or caveat?

  • Self-employed owners whose accounts lag behind reality.
  • Businesses recovering from a bad year with equity and a dated exit.
  • Owners with ATO arrears who want to clear them in one step.
  • Borrowers who need speed and can’t wait for a year-end set of accounts.
  • Companies borrowing against a director’s property, with the director as guarantor.

When isn’t low doc the right move?

  • When full doc is easy. If your accounts are current and strong, a bank refinance will usually cost less.
  • When the exit is weak too. Low doc relies on the exit; without one, there’s nothing to lend on.
  • When the first mortgage is in serious default. Refinancing the whole debt into a private first mortgage, or selling, may be more realistic.
  • When the purpose is personal. These are business-purpose loans only.

How does low doc behind your bank compare?

Low doc caveat or second Low doc private first (refinance) Bank alt-doc loan Unsecured no-doc loan Sell the property
Bank loan Stays in place Paid out Replaced Untouched Paid out
Paperwork ID, ownership, statement, exit Similar, plus payout Declarations, BAS, more Bank statements Sale contract
Speed Same day possible to $250k 24–48 hours possible Weeks Days Weeks to months
Cost Higher than a first mortgage Lower than a second Lowest if approved Often high Agent and sale costs
Best for Short need, bank loan worth keeping Bigger need or bank in arrears Long-term borrowing Small, no property When the asset should go anyway

How fast, and what it costs (without the guesswork)

Same-day funding is possible for property-secured amounts from $20k to $250k once documents are in; 24–48 hours is possible up to $5m. Each loan is priced on its security, LVR, term and exit, aiming for the sharpest price your situation allows. Expect interest (prepaid or capitalised), a small assessment fee that varies per loan and appears on the Letter of Offer, legal and registration costs, and discharge costs. A second mortgage or caveat generally costs more than a first mortgage because it ranks behind.

Illustrative example (net funds): a Brisbane landscaping contractor has unlodged returns for the last year, $95k of ATO debt and a $180k contract starting next month. The owner’s home is worth about $1m with $520k owing to a bank, payments up to date. Illustrative: lending to a combined 65% of value allows total debt of $650k, so there’s $130k of headroom.

  • Loan: $125k low doc caveat loan for 10 weeks, interest capitalised
  • Less ATO payout: $95k
  • Less assessment fee and legal costs: about $6k
  • Working capital released: about $24k for the contract start-up
  • Exit: the contract’s first two payments, backed by the signed head contract Because Queensland caveats commonly last no more than three months, the plan includes converting to a registered second mortgage if the payments run late. Local points are on the Brisbane private lender page.

Frequently asked questions

I'm a sole trader and my last two tax returns aren't lodged. Can I get a low doc caveat loan against my house for the business?

Possibly, if there's equity behind the existing mortgage and a clear way to repay. Unlodged returns don't rule you out, but the lender will want to understand why and what the exit is. Often part of the plan is getting the returns lodged so a bank refinance becomes possible.

What's the minimum paperwork for a low doc second mortgage?

Photo ID for every owner and guarantor, your ABN or company details, proof of who owns the property, a recent statement for the first mortgage, a short statement of the business purpose and evidence of the exit. That's the core; the lender may ask for one or two items specific to your deal.

Can an accountant's letter replace financial statements?

It can help, especially if it confirms income, explains a one-off bad year or sets out how the loan will be repaid. It's supporting evidence rather than the decision itself, which still rests on the property's equity and the exit.

My bank loan on the property is two payments behind. Does that stop a low doc second mortgage?

It makes it harder, not impossible. Arrears on the first mortgage are a direct risk to the second lender, so the usual answer is to clear them from the new loan at settlement and show how payments will be kept up. If the arrears can't be fixed, refinancing the first mortgage may be the better structure.

Does low doc mean no ID checks?

No. Identity checks are never skipped. Electronic conveyancing rules require reasonable steps to verify the identity of the people signing, so every owner and guarantor needs current photo ID.

My Gold Coast investment unit has a first mortgage with a major bank. Will they need to agree to a second mortgage?

Some first mortgages require the existing lender's consent before a second mortgage is registered, so your solicitor should check the bank's terms. A caveat loan may be an alternative while consent is sought, and it can later convert to a registered second mortgage.

I have $140k of ATO debt that's more than 90 days overdue. Is that on my credit file?

It may be. The ATO can report a business's tax debt to credit reporting bureaus when at least $100,000 is overdue by more than 90 days and the business isn't actively engaging, for example through a payment plan. A low doc secured loan that clears the debt is assessed case by case on equity and exit.

Is a low doc caveat loan more expensive than a full doc one?

The documentation level isn't priced on its own. Each loan is priced on its security, loan-to-value ratio, term and exit. A caveat or second mortgage generally costs more than a first mortgage because the lender ranks behind, and a thin exit case will weigh more than missing tax returns.

Can a low doc loan be done in my company's name when the property is in my name?

Yes, it's common. The company borrows and you, as owner of the property, give the security and usually a guarantee. Both need to sign, and the lender needs the company's details and your ID.

What counts as a good exit when I can't show strong financials?

The strongest exits are documents with someone else's signature on them: a sale contract, a refinance approval, a contract with payment dates. A forecast from your accountant is weaker but useful. 'Business will pick up' isn't an exit.

Can I use a low doc second mortgage to consolidate expensive online business loans?

Yes, if the equity supports it and the new loan has a believable exit. Replacing daily or weekly debits with one secured loan, where interest can be capitalised, often frees up cash flow. The lender will want payout letters for each debt being cleared.

How quickly can a low doc caveat loan fund?

Same-day funding is possible for property-secured amounts of $20k to $250k once documents are in, and 24–48 hours is possible up to $5m. A short document list helps, but the speed still depends on the documents that are needed being ready.

On top of the low doc paperwork, will I be paying for a property report?

No. There's no formal valuation required; the lender assesses the property itself. That keeps the file short and saves the cost of a report.
