Quick answer
A caveat loan is usually quicker to settle because the lender lodges a notice on title rather than registering a mortgage, which suits short terms of weeks to twelve months with a firm exit. A second mortgage is registered behind your first lender, takes a little longer and suits terms of months to a few years with regular repayments. Both leave your existing home loan in place. Choose by term, exit and amount, not speed alone.
Key points
- Caveat: lighter, quicker, best for short terms with a lump-sum exit.
- Second mortgage: more formal, suits longer terms and regular repayments.
- Both leave your first mortgage untouched.
- Your first lender's rules on second charges can decide it for you.
If you own a home with equity and need money for the business, two options come up again and again: a caveat loan and a second mortgage. Both let you borrow without refinancing your existing home loan. Both are offered by private and specialist lenders who can move far faster than a bank. And both are often described in the same breath, which makes it hard to know which one you actually need.
The short version: a caveat is the sprint, a second mortgage is the middle distance.
The core difference
A caveat is a notice lodged on your property’s title. It tells anyone searching the title that the lender claims an interest. It’s quick to prepare and lodge, but it’s a less formal type of security than a registered mortgage, so lenders use it for short terms with a clear end.
A second mortgage is a registered mortgage that ranks behind your existing first mortgage. It’s a more formal security, so it takes slightly longer to put in place, but it suits longer terms and larger amounts, and it can be repaid gradually.
Side by side
| Caveat loan | Second mortgage | |
|---|---|---|
| Security | Caveat lodged on title | Registered mortgage, second position |
| Typical term | A few weeks to 12 months | 6 months to a few years |
| Repayment style | Often a lump sum at the end | Regular repayments, or interest-only then lump sum |
| Speed | Usually the quickest | Slightly longer; first lender consent can add time |
| Paperwork | Lightest | A little more |
| Best exit | A dated event: sale, refinance, contract payment | Ongoing income, or a later refinance |
| Typical uses | Tax bills, deposits, short bridges | Expansion, consolidation, longer projects |
When a caveat is the better fit
- You need the money within days.
- The term is short, measured in weeks or a few months.
- You have a specific, dated exit, such as an exchanged sale contract, a confirmed contract payment or an approved refinance.
- You’d rather repay in one hit than make monthly repayments.
When a second mortgage is the better fit
- You need the money for longer than a few months.
- You’d prefer to repay gradually from business income.
- You’re consolidating several debts into one repayment.
- The exit is real but further away or less certain, such as refinancing once next year’s returns are lodged.
- The amount is larger and the lender prefers registered security.
The speed question, honestly
Caveats usually settle faster, but the gap is often smaller than people think. Once title, valuation and signers are sorted, $20k to $250k is possible same day through either structure with the right lender. Where second mortgages lose time is usually one of three things: the first lender’s consent requirement, a slightly longer document process, or a lender that wants to see more about how you’ll make regular repayments.
If your deadline is genuinely today or tomorrow, a caveat is usually the safer bet. If you have a week, the choice should come down to term and exit rather than speed.
Check your first mortgage
Before choosing, look at your existing home loan. Some lenders’ contracts restrict other interests on the title, or require you to ask before a second mortgage is registered. A few may treat an unapproved second charge as a breach. This isn’t a reason to panic, but it is a reason to tell us who your lender is at the start. It may push you towards one structure or the other.
Cost: compare like with like
Short caveat loans are priced for speed and convenience, and their monthly cost can look high. Second mortgages are often priced lower per month but held for longer. The fair comparison is the total amount you’ll repay over the time you actually expect to hold the loan, including establishment, valuation, legal and discharge costs. A caveat held for two months can cost less in total than a second mortgage held for two years, even if its monthly cost is higher.
Watch the extension trap. If you take a caveat loan expecting a sale in six weeks and the sale is delayed by three months, extension fees can make it the more expensive choice. If your exit date is uncertain, a second mortgage with a longer term may be the safer bet.
Two illustrative examples
The caveat case. A Sunshine Coast building company owes $88,000 to the ATO and has a director penalty notice. It has a $210,000 progress claim approved and due in five weeks. The directors’ home has strong equity. A caveat for three months pays the ATO directly within two days, and the progress claim clears the loan. Illustrative only.
The second mortgage case. A Rockhampton auto electrician wants to consolidate two short-term online loans and an overdue equipment account, about $115,000 in total, and drop from daily repayments to monthly ones. There’s no single event that will repay it; the plan is to repay from trading over two years. A second mortgage over the owner’s home for 24 months pays out all three debts at settlement. Illustrative only.
Paperwork for each
For a caveat, expect to provide the property details, a current loan statement, ID for every owner and evidence of your exit. For a second mortgage, add a little more about how regular repayments will be met, often recent business bank statements.
A simple way to decide
Ask yourself three questions:
- How long will I need the money? Under twelve months with a firm end date points to a caveat. Longer points to a second mortgage.
- How will I repay? One lump sum from a known event points to a caveat. Regular repayments from income point to a second mortgage.
- What does my first lender allow? If second charges are restricted, that may decide it.
If you’re still unsure, tell us the situation and we’ll recommend one, with the reason.
Either way, protect yourself
Both structures put your property on the line if the loan isn’t repaid. Borrow only what’s needed. Choose a term with room past your expected exit. Read the full contract and get independent legal advice. Make sure every owner on title understands the arrangement. And keep the lender informed early if anything changes.

Frequently asked questions
Which is cheaper?
It depends on the lender, the amount and the term. Short caveat loans are priced for speed and can cost more per month, but they're held for less time. Compare the total repayable over the period you'll actually hold the loan.
Can a caveat loan be converted into a second mortgage later?
Sometimes, with the same or a different lender. It's usually treated as a refinance, with its own costs, so it's better to choose the right structure first.
Does a second mortgage need my first lender's consent?
Some first lenders require consent or notification before a second mortgage is registered. Others don't. Your loan contract will say, and we check early.
Which is better for paying out several debts?
Usually a second mortgage, because consolidating debts tends to need a longer term with regular repayments rather than a short lump-sum exit.
