A caveat is an equitable interest registered against title; a first mortgage is the registered legal charge. Caveats are faster and cheaper to register but provide weaker enforcement rights — first mortgages are slower to set up but cleaner to enforce. The choice is duration-driven: under 6 months, caveat often wins on total cost; over 6 months, first mortgage almost always wins. A caveat loan can settle in 48 hours; a first mortgage takes 5 to 10 business days. The reason isn't speed in the abstract — it's what the lender can do if everything goes wrong.
This guide walks through what each instrument actually is, what happens on default, why the pricing differs, and the duration rule that decides which one to use — with a worked $500,000 example showing why the wrong instrument on a 9-month deal costs the borrower an extra $20,000.
What each instrument is, mechanically
TL;DR: Both create rights against real property. They do it differently — and the difference matters when the loan needs to end. A caveat is a hold on the asset; a first mortgage is a claim on it.
A caveat first. A caveat is an equitable interest lodged with the relevant state's land titles registry. Short form, often registered within 24 to 48 hours. Once it's there, the registered owner can't sell or further mortgage the property without the caveator's consent or formally removing the caveat. It "prevents dealing" with the title. It does not, by itself, give the lender a power of sale or a direct ranking against subsequent registered mortgages. Cheaper to register, faster to register, weaker if things go wrong.
First mortgage. A registered legal charge on title. The mortgagee — the lender — has a power of sale on default, ranks ahead of all subsequent encumbrances, and the security is recorded on title with full legal effect. Setting it up takes longer — typically 5 to 10 business days — because the formalities are real: proper deeds, registration, usually a formal valuation, sometimes title insurance.
The structural difference: a caveat is a hold on the asset; a first mortgage is a claim on it.
Enforcement — what happens when a loan goes sideways
TL;DR: When a loan defaults, the instrument determines what the lender can actually do — and that's what the pricing reflects. A caveat is a lever for negotiation. A first mortgage is a sword for recovery.
Caveat default. The caveat itself doesn't grant a power of sale. The lender's primary remedy is to sue on the loan agreement — the personal debt — and use the caveat to block the borrower from selling or refinancing without engagement. That forces a negotiation, but it doesn't directly recover the lender's capital. The lender can apply for a court order for sale, but it's a process. Weeks to months. Significant legal spend. Result is uncertain. A caveat is a lever for negotiation, not a sword for recovery.
First mortgage default. Power of sale on default. The mortgagee can sell the property without the borrower's consent — subject to statutory notice periods and conduct-of-sale duties. The lender ranks first in distribution of sale proceeds. The recovery process is faster, cleaner, more predictable. And the borrower knows this — which is why most first-mortgage defaults resolve through refinance or sale rather than enforcement. The threat of clean recovery often resolves the deal without needing to use it.
Net effect: lenders pricing a caveat have to assume the recovery path is harder. So they price the risk position higher.
Pricing — same asset, two instruments, two different rates
TL;DR: Pricing reflects the lender's enforcement risk, not the property itself. Same asset, two instruments, two different rates. The price is the lender's bid for the risk position, not for the property.
Three pricing bands as at May 2026:
- First mortgage, under 65 per cent LVR: 8 to 11.5 per cent per annum. Establishment fee 1 to 2 per cent.
- First mortgage, 65 to 75 per cent LVR: 10 to 13.5 per cent per annum. Establishment fee 1.5 to 2.5 per cent.
- Caveat or second mortgage: 12 to 18 per cent per annum. Establishment fee 2 to 3 per cent.
Why the gap on the same asset: not because the property is different. Because the lender's recovery path is harder. The price is the lender's bid for the risk position, not the property.

The duration rule — worked example on $500,000
TL;DR: Total cost depends on the term. The caveat's speed advantage doesn't compound over time. The pricing penalty does. Under 6 months and you need speed — caveat. Over 6 months, or you have a week — first mortgage.
Same property. Same borrower. Same $500,000 ask. Two scenarios.
Scenario A — 3-month term
Caveat at 15% pa:
- Interest: $500,000 × 15% × 3/12 = $18,750
- Establishment fee (2.5%): $12,500
- Total cost: $31,250. Settles in 48 hours.
First mortgage at 11% pa:
- Interest: $500,000 × 11% × 3/12 = $13,750
- Establishment fee (1.5%): $7,500
- Total cost: $21,250. Settles in 7 to 10 business days.
Difference at 3 months: $10,000 more to use the caveat. If you need to settle in 48 hours, that $10,000 is the price of the deal itself. If you have a week, the first mortgage saves it.
Scenario B — 9-month term
Caveat at 15% pa:
- Interest: $500,000 × 15% × 9/12 = $56,250
- Establishment fee (2.5%): $12,500
- Total cost: $68,750.
First mortgage at 11% pa:
- Interest: $500,000 × 11% × 9/12 = $41,250
- Establishment fee (1.5%): $7,500
- Total cost: $48,750.
Difference at 9 months: $20,000 more to use the caveat. The longer the term, the more the pricing differential compounds. The speed advantage doesn't.
The rule
Under 6 months and you need speed — caveat. Over 6 months, or you have a week — first mortgage. The cheapest rate with the wrong instrument costs more than the higher rate with the right one. There are exceptions — the most common is a caveat behind an existing first mortgage that can't be discharged, where the caveat is the only structurally available option regardless of term. But for the typical decision (new private deal, clean security, choice of instrument), the duration rule holds.

When neither is the right tool
TL;DR: Both caveat and first mortgage instruments are business-credit tools. Consumer purpose sits outside both entirely.
Specifically:
- Consumer purpose — owner-occupied home loan, personal loan, debt consolidation — sits outside this entirely. That's regulated consumer credit. Esteb & Co (Australian Credit Licence #389087) is the licensed pathway for those.
- No credible exit inside the term. Neither instrument fixes a deal where the borrower can't actually repay at the end. The caveat is faster; the first mortgage is cleaner; both fail if the exit fails.
- Marginal security at high LVR. A caveat on a property the lender can't easily realise on is a worse position than declining the deal.
Frequently asked questions
Can a caveat be converted to a first mortgage later?
Yes — and it's a common structure where the borrower needs the 48-hour speed first and the cheaper longer-term pricing later. The caveat is lodged immediately, the first mortgage is registered once the formalities complete (typically 7-10 days), and the loan agreement reflects the transition. The borrower carries the establishment costs of both registrations, so this only makes economic sense where the speed component is genuinely worth it.
What state-by-state differences matter?
Caveat lodgement procedures vary by state — NSW, VIC, QLD, WA, SA each have their own land titles registry and rules. Practical effect on borrowers is small (the lodgement happens behind the scenes). The relevant property law generally aligns on the core point: a caveat prevents dealing but doesn't grant power of sale.
Why are caveat loans sometimes quoted in per-month rates?
Some caveat lenders quote pricing as a monthly rate — "1.25 per cent per month" reads as cheaper than "15 per cent per annum" even though they're the same number. Always convert monthly rates to annualised rates for comparison. Anything that won't quote in annualised terms is signalling something about the pricing.
Can I get a caveat loan on an investment property with an existing bank first mortgage?
Yes — that's actually one of the most common structures. The bank first mortgage stays in place, the caveat sits behind it, and the lender accepts the subordinated position in exchange for the higher pricing. The bank usually doesn't need to consent to a caveat the way they would to a registered second mortgage, though notice is normally given.
The bottom line
The choice between caveat and first mortgage isn't about which is "better" — it's about which fits the deal. Under 6 months, speed-critical, security supports the higher pricing: caveat. Over 6 months, you have a week, you want the cleanest recovery position: first mortgage. The wrong instrument on the right deal costs real money. Get the duration right first, the instrument follows.
