Second Mortgage vs Caveat Loan: Which Sits Better Behind the Bank
They both fund deals where the bank is already on title. They rank differently, settle at different speeds, and price for very different reasons. The right choice usually comes down to whether the first mortgagee will play, and how long you can wait.
The bank is already on title, so what sits behind it
The bank is on title because the first mortgage is registered there. Anything funded after that point sits behind that registered interest. The two products self-employed business owners reach for in this space are a registered second mortgage and a caveat loan. They look similar from the outside, sit on the same property, and both rely on the equity the first mortgage has not absorbed. Underneath, they are different instruments with different ranking on title and different recovery profiles.
In practice, choosing between them is a structural call, not a marketing call. The deal type, the speed needed, the willingness of the first mortgagee, and the size of the equity buffer all push you toward one or the other. The rest of this post is the same conversation I have with self-employed business owners when both options are on the table.
Structurally, what is the difference
A registered second mortgage is what the name suggests. The lender registers a mortgage in second position behind the existing first, with the consenting first mortgagee on record. A caveat loan is different. The lender lodges a caveat against the title, signalling a caveatable interest, but no mortgage is registered. The first mortgagee does not need to consent for a caveat to be lodged, which is the most important practical difference between the two.
That distinction drives almost everything else. The second mortgage has a registered security interest sitting in the ranking-on-title hierarchy at position two. The caveat is a noted interest, not a registered mortgage. In a default scenario, the registered security pulls before the caveat. Lenders price the difference because they are pricing their own recovery position, not just the borrower's risk profile.
| Dimension | Registered Second Mortgage | Caveat Loan |
|---|---|---|
| Ranking on title | Registered in second position behind the first mortgage. | Caveat lodged against title, no mortgage registered. |
| First mortgagee consent | Required. The consenting first mortgagee must agree. | Not required. Caveat lodges without first mortgagee involvement. |
| Typical settlement window | Approximately 8 to 14 days indicative, varies by lender, driven by consent timing. | Typically faster, often inside the same week, varies by lender. |
| Pricing band | Approximately illustrative pricing bands vary by lender, generally lower than caveat for the same deal. | Approximately illustrative pricing bands vary by lender, generally higher to reflect the speed-cost tradeoff. |
| Term length | Typically structured for medium term, varies by lender. | Typically short term, varies by lender, often a bridge to a registered solution. |
| Recovery position | Registered interest, sits second in the hierarchy. | Noted interest, typically sits behind any registered mortgage. |
Speed-cost tradeoff: faster, slower
The speed gap is not about lender appetite. It is about whether a registration step is required at all. Caveat loans skip the first mortgagee consent process, so they move quickly. Registered second mortgages wait on consent, then settle.
Faster: Caveat Loan
- No registration of a new mortgage means no first mortgagee consent step.
- Caveat lodgement is administrative, not a registered security event.
- Useful when settlement timing drives the deal: a missed contract, a tight settlement, a stalled receivable.
- Pricing reflects the speed and the noted-interest position, illustrative only and varies by lender.
- Best for short-term capital with a clear, dated exit.
Slower: Registered Second Mortgage
- First mortgagee consent is required, which adds approximately 8 to 14 days indicative settlement, varies by lender.
- Registered second-position security improves recovery for the lender, which usually improves price for the borrower.
- Suited to medium-term capital where a longer term and lower price beat the faster path.
- Better fit when the deal can absorb the consent timeline.
- Often the right choice for acquisition finance, equity release for working capital, or refinancing from short-term capital.
When the second mortgage sits better
The second mortgage sits better when the deal has time, the consenting first mortgagee will play, and the borrower needs term and price more than speed. That is most refinances, most equity-release plays, and most acquisition deals where due diligence already eats up the calendar. The first mortgagee consent is the gating step. If the first lender will consent, the second mortgage almost always wins on cost over a multi-month or multi-year horizon.
From the underwriter's seat, the question is whether the equity behind the first mortgage is large enough, whether the borrower's serviceability holds at a higher gross debt position, and whether the LVR after the second sits inside the lender's appetite. LVR is the driver. Pricing flexes with it. So does first mortgagee willingness, because a low combined LVR makes consent easier to obtain. For a structural primer on what lenders check first, this walkthrough of lender criteria for second mortgage business loans is the cleanest companion read.
When the caveat loan sits better
The caveat loan sits better when speed is the deal. A receivable has stalled, a contract is mid-flight, a settlement date is fixed and the registered path will not make it. The caveat also sits better when the consenting first mortgagee will not consent at all, which can happen on certain residential first mortgages or where the first mortgagee's policy excludes second registrations. In that case, the caveat is not the cheaper option, it is the only option.
The trade is short-term capital at a higher illustrative pricing band, with an exit plan defined up front. Most clean caveat deals end with a refinance into something registered. That can be a second mortgage with a different lender once consent is sorted, or a refinance into private lending structured over a longer term, or a return to the first mortgagee with a restructured facility. For a wider-angle view of the property lending stack, the 2026 property lending stack piece sits next to this one.
Using a second mortgage to buy a business
An overlooked use case for a registered second is the acquisition deal. A self-employed owner wants to buy a competitor, fund a partner buy-out, or acquire an adjacent operation. The cleanest source of capital is often the equity sitting behind the first mortgage on a property already owned. A second mortgage to buy a business can fund the deposit, the goodwill component, or the full purchase, depending on the equity buffer and serviceability.
Why a second mortgage and not a caveat for this use case? Acquisition deals carry due diligence timelines. The buyer is reading financials, contracts, customer concentration, lease terms, and supplier exposure. That work takes weeks, sometimes longer. The first mortgagee consent timeline overlaps cleanly with that diligence window. By the time the deal is ready to settle, the consent is sorted and the second registers. Pricing on a registered second is also a closer fit for an acquisition that is meant to operate for years, not months.
Where the caveat does fit acquisitions is the rescue scenario: a settlement date is fixed, a contract is at risk, and only a same-week funding solution will save the deal. In that case, the caveat funds settlement and the buyer refinances into a registered second once the bank consent comes through. The caveat is the bridge, the second is the destination.

Frequently asked questions
No, a caveat loan and a second mortgage are different instruments with different ranking on title. A caveat loan sits behind a caveat lodged on title, which signals a caveatable interest. A second mortgage is a registered mortgage in second position, which requires consent from the first mortgagee. They are different instruments with different ranking on title and different recovery profiles.
Yes, a registered second mortgage over a property you already own can fund a business acquisition or partner buy-out in many cases. The equity behind the first mortgage is often the cleanest source of capital for a buy-in or shareholder restructure. Pricing and serviceability are illustrative and vary by lender. The lender criteria walk-through covers what assessors look at first.
Caveat loans typically settle faster because no mortgage is registered and no first mortgagee consent is required. Registered second mortgages take longer because the first mortgagee must consent, which adds approximately 8 to 14 days indicative settlement, varies by lender. Speed is the speed-cost tradeoff in this product pair. The 48-hour caveat settlement walk-through shows how fast the caveat lane can move when speed matters.
Yes, registering a second mortgage requires the consenting first mortgagee to allow the second-position security to be registered behind their loan. Without that consent, a registered second cannot proceed and the borrower may need to consider an unregistered caveat instead, then refinance later when consent or a different first mortgagee is in place. The second mortgage loans page covers how the consent step is sequenced.
The first mortgage ranks first, the registered second mortgage ranks second, and any caveat lodged afterwards typically sits behind both as a noted interest. In a default scenario, recovery follows that ranking-on-title hierarchy in order, which is why pricing reflects the lender's exposure at each tier. The private lending entry on the glossary covers how non-bank pricing tiers map onto this hierarchy.
