How second mortgages rank behind the first

“Second” isn’t a marketing label. It describes exactly where the loan sits in the queue of interests on your title, and that position decides who is repaid first, whose permission matters and what happens if the property has to be sold. Understanding the queue makes it much easier to see why a second mortgage is priced and structured the way it is.

What does it mean for a mortgage to “rank” first or second?

Every registered mortgage is recorded on the title by the state land registry. When two or more mortgages sit on the same title, the law needs a rule for who comes first. In Torrens title systems, the rule is lodgement order.

Queensland’s Land Title Act says registered instruments have priority according to when they were lodged, not when they were executed. The registry’s endorsed date and time is presumed correct unless proved otherwise. Your bank lodged its mortgage when you bought or refinanced, so it holds first place. A private lender lodging later takes the next place.

In practice, ranking means:

• First mortgage: first claim on the property for its full debt.
• Second mortgage: a claim on what’s left after the first lender is fully repaid.
• Third and later mortgages: each behind the one before it.

That’s the whole reason a second mortgage generally costs more than a first. The second lender is exposed to anything that eats into the equity ahead of it.

Does the first lender have to agree to a second mortgage?

Often, yes, but the requirement usually comes from your loan contract rather than from the land registry. Many first mortgages contain a term that the borrower must not give further security over the property without the existing lender’s permission. The Queensland Government’s own lending terms are a clear public example: borrowers must get its permission, as the existing lender, before a second mortgage goes on the title.

What the first lender typically wants to know:

• who the second lender is and how much is being borrowed;
• that its own position as first mortgagee isn’t affected;
• that the bank loan will stay up to date.

What you should do:

1. Ask your solicitor to read the first mortgage terms before you sign anything new.
2. Request the bank’s permission early, because its turnaround can be the slowest part of the deal.
3. Keep the first mortgage repayments current throughout the second loan’s term.

If the bank says no, a second mortgage over that property is usually off the table. The options then are another property as security, or refinancing everything into one private first mortgage.

Can two lenders agree to change the order?

Yes. Ranking by lodgement is the default, but mortgagees can agree to rearrange it. In Queensland this is done with a Form 30 Mortgage Priority, which records the order of all affected registered mortgages and is signed by both the lender giving up priority and the lender receiving it.

Elsewhere you’ll often hear the broader term “deed of priority”, which is an agreement between lenders about who is repaid first and, sometimes, up to what amount. Priority arrangements are mostly used in larger or more complex deals. For a typical business second mortgage, the second lender simply ranks behind the existing bank.

What happens to each mortgage when the property is sold?

On an ordinary sale you control, the process is calm. Your conveyancer or solicitor obtains payout figures from both lenders, and at settlement each mortgage is paid out and discharged so the buyer gets a clear title.

Order at settlement	Who is paid	What happens on the title
1	Sale costs and adjustments	—
2	First mortgage lender	First mortgage discharged
3	Second mortgage lender	Second mortgage discharged
4	Any later secured lenders	Their mortgages discharged
5	You	Balance of the sale price

Illustrative example: a Geelong builder sells a townhouse for $1.1m. Illustrative: after $40k in sale costs, the bank’s first mortgage of $600k is repaid, then the private second mortgage of $250k. The builder receives the remaining $210k, and both mortgages come off the title on the same day.

You can read about the day itself in our guide to what happens at settlement.

What if a lender has to enforce its mortgage?

Nobody plans for this, but it’s worth understanding. Under Western Australia’s Transfer of Land Act, a mortgagee’s power of sale arises after default and after a notice has been served on the borrower, with the period set by the Act or the mortgage.

Two rules then show why ranking matters so much:

• When the first lender sells, registering its transfer removes encumbrances lodged after its mortgage. In other words, the second mortgage comes off the title and the second lender is left with a claim on the leftover money, not the property.
• When a second lender sells, the first mortgage is not removed automatically, because it ranks ahead. It has to be paid out and discharged.

The order for applying sale money is set out in the same Act: the costs of the sale first, then the selling lender’s debt, then later-ranking mortgages in order of priority, with any surplus paid to the owner.

The practical lesson for borrowers is simple. Keep the first mortgage up to date, and choose a second mortgage term that sits comfortably inside a realistic exit. Our pillar page on second mortgage business loans explains how exits are built into the term.

How is a caveat different from a ranked mortgage?

A caveat isn’t a mortgage at all. It’s a notice on the title that stops certain dealings being registered until the caveat is withdrawn, removed or lapses. Caveat loans are popular for speed, but the lender’s position is less settled than a registered mortgage’s, which is why a caveat loan can later be converted into a registered second mortgage.

We unpack the differences on our caveat loans page, and compare all three structures in first vs second mortgage vs caveat. If you’d rather have someone look at your actual title than read about it, ask a specialist to check your position.

Where would your loan rank? See if you qualify

You don’t need to work out priorities, consents and payout orders on your own. Send a short enquiry and a specialist will read your title position and tell you what’s realistic.

There’s no credit check to enquire, and your details aren’t passed around to a string of lenders. Be precise about the property, who holds the first mortgage and what’s still owed on it, because accurate figures are what get you a reliable answer the first time. Our lending partner fundU funds directly, so the answer comes from the people who would actually make the loan.
