Caveat loan vs second mortgage: which suits your deal?

Private credit gives borrowers two ways to take a second-ranking position against property: lodge a caveat or register a second mortgage. The instrument shapes the consent path, the settlement timeline, the lender's enforcement rights, and the rate the borrower pays. Get it wrong and the deal either misses its window or costs more than it needed to.

Aurelius Private are private lending brokers — we arrange and place both caveat loans and second mortgages with lenders across our 131+ non-bank panel. This is the framework we apply when both instruments are on the table.

The core difference in one sentence

A registered second mortgage creates a legal charge over the property in second position; a caveat records an equitable interest without registering a mortgage. Both sit behind a first mortgage. Neither is inherently better — the right instrument depends on the deal.

Security ranking and what it means for lender appetite

On title, the hierarchy runs: first mortgage, registered second mortgage, caveat. Recovery follows that order in a default, which is why pricing reflects position.

Lenders writing second mortgages hold a registered security interest and carry statutory power of sale if the borrower defaults. Lenders writing caveat loans hold a weaker enforcement position: no automatic power of sale, and court proceedings required to force a sale.^[1] That enforcement gap is why caveat pricing runs higher than second mortgage pricing at equivalent LVRs. The lender prices the additional recovery complexity into the rate.

For the borrower, this matters when sizing up exit risk. A short deal with a contracted exit — refinance by a fixed date, sale already exchanged — carries that enforcement limitation without much consequence. A longer deal with an uncertain exit is a different conversation.

First mortgagee consent — where deals stall

Registering a second mortgage requires consent from the first mortgagee. For major bank first mortgages, that process typically takes 8–14 business days and attracts a consent fee, commonly $200–$500.^[2] Some first mortgagees decline outright where the combined LVR stretches past their internal thresholds.

A caveat does not require the first mortgagee's consent to lodge on title — it bypasses that process entirely. This is the primary reason borrowers reach for a caveat: the timeline won't accommodate the consent window, or the first mortgagee will not agree.

Check the first mortgage terms before relying on that. Most first mortgage loan agreements contain a negative pledge clause — a covenant that prohibits the borrower from placing further encumbrances on the property without lender consent. Lodging a caveat without that consent doesn't need the first mortgagee's agreement from a title mechanics standpoint, but it may constitute a default under the first mortgage agreement.^[1] Before structuring the deal as a caveat, the first mortgage terms need to be reviewed. Bank first mortgages are almost universally restrictive on this point. Non-bank first mortgages vary.

Settlement speed vs cost: the comparison

Rates are market indicatives as at mid-2026 and move with LVR, security type, exit clarity, and lender.^[3][4] Where the consent path is open and the timeline allows it, a second mortgage is almost always the right call on cost. The rate and fee differential over a 6-month term is real.

Enforcement — what happens if the exit doesn't land

This is where the choice stops being about rate.

A registered second mortgagee has statutory power of sale.^[5] If the borrower defaults, the lender can exercise that power without court intervention (subject to required notices), appoint a receiver, and recover from sale proceeds in their registered position.

A caveat lender has no equivalent right. To force a sale, the lender must apply to court for an order for sale or appointment of a receiver — a slower, more expensive path that puts the outcome in a judge's hands.^[1] The underlying equitable interest also needs to be properly documented; a poorly structured caveat can be challenged and removed if the caveatable interest lacks evidentiary support.

For short-term deals where the exit is contracted and imminent, this distinction rarely matters in practice. For anything beyond 3 months with a soft exit, it changes the risk profile — and lender appetite on the panel reflects that.

When to use a caveat

• The first mortgagee will not consent, or the deal structure requires bypassing that process.
• Settlement must happen in 24–48 hours — a tax office deadline, a commercial contract date, a refinance gap that closes in days.
• The term is 1–3 months with a clean, contracted exit (refinance pre-approved or sale exchanged).
• The loan size sits in the range where caveat lenders are active on the panel — typically $100K–$2M, though larger deals exist.

When to use a second mortgage

• The first mortgagee will consent and the borrower has days, not hours.
• The term is longer than 3 months — the registered security position matters more as exposure extends.
• The borrower wants lower cost and can absorb the consent window.
• The combined LVR sits within the appetite of second mortgage lenders on the panel — typically to 75–80% on metropolitan residential security.

What the broker assessment covers

When Aurelius Private structures either deal, we work through the same checklist regardless of which instrument looks right at the outset.

First, security position: first mortgage balance, current valuation, combined LVR, and which lenders on the panel are active at that exposure in that security class.

Second, exit: what is the repayment source, and is it contracted? A refinance with a written pre-approval is a different exit risk from an expected sale in six months with no buyer identified.

Third, first mortgage terms: is there a negative pledge clause? Will the first mortgagee consent if required? If they will, does the timeline allow it? If not, can the deal be structured as a caveat without triggering a default under the first mortgage?

Finally, term and cost: given the borrower's timeline, does the 24-hour settlement of a caveat justify the rate premium, or can the deal wait the consent window and take a second mortgage at lower cost over the full term?

One scenario, two instrument options. The right one changes which lenders on the panel are relevant, what the deal costs, and what happens if the exit slips.
