Investing in first and second mortgages: how ranking protects your capital

Where your loan ranks on the title decides who is repaid first if a property is ever sold. Here is how first and second mortgage positions work for an investor, and how each is protected.

When you invest in a first mortgage, you are first in line to be repaid if the property ever has to be sold. A second mortgage ranks behind the first lender, so it is protected by keeping total debt, first plus second, within a maximum LVR: 80% of value on residential property with HomeSec, and lower on commercial property.

HomeSec Business Finance, an Australian private lender founded in 2004, offers wholesale investors the chance to co-fund short term business loans secured by both first and second mortgages over Australian real estate. HomeSec puts its own money into every loan it offers, in the same position as yours. This guide explains what each position means for you as the lender.

What do “first” and “second” mortgage mean for an investor?

The words describe ranking, sometimes called priority. A property can carry more than one mortgage. The first mortgage has the first claim on the property; the second mortgage has the next claim; and so on.

Ranking only really matters in one situation: when a borrower defaults and the property is sold to repay the debt. The sale proceeds are then paid out in order:

  1. The costs of the sale and of enforcing the security.
  2. The first mortgagee: principal, interest and its costs.
  3. The second mortgagee: principal, interest and its costs.
  4. Anything left goes to the property owner.

If the loans are repaid normally, which is the expected outcome, ranking never comes into play. Both lenders are simply repaid from the borrower’s exit, such as a sale, a refinance or business proceeds. But a careful investor always asks the question in advance: if this property had to be sold, where would I stand?

What does “registered” mean?

A registered mortgage is one recorded on the property’s title at the state land titles office. Australia uses the Torrens title system, under which the title register is the official record of who owns a property and who has an interest in it. Registered mortgages generally rank in the order they are registered.

Registration does three things for you. It makes your interest public, so the property cannot be quietly sold or re-borrowed against without your debt being dealt with. It fixes your place in the queue. And it gives the lender the legal right, if the borrower defaults, to take possession and sell the property, known as becoming a mortgagee in possession.

With HomeSec, you are named on the registered mortgage for your exact contribution, alongside HomeSec. You are not relying on a fund or a trustee to hold the security on your behalf. Your name is on the title record.

How does a first mortgage position work in practice?

Take a simple illustration. A business owner offers a property valued at $1,500,000 as security, with no other debt on it. A loan of $900,000 is made, secured by a first mortgage.

AmountShare of value
Property value$1,500,000100%
First mortgage (this loan)$900,00060% LVR
Equity buffer$600,00040%

In this example, the property would need to fall 40% in value, before allowing for sale costs and accrued interest, before the loan was fully exposed. The deepest national fall in Australian home values in recent decades was about 8.4% in 2017–19, and the 2022–23 fall of about 7.5% was fully recovered by November 2023.

A first mortgage is the simplest position to understand. Nobody ranks ahead of you, and the whole value of the property stands behind the loan.

How is a second-mortgage position protected?

A second-ranking position is protected by the total LVR: all the debt secured on the property, added together, as a share of its value. HomeSec’s rule is a maximum 80% total LVR on residential property, and lower on commercial property.

Here is an illustration. A business owner has a home valued at $2,000,000 with an existing bank mortgage of $1,000,000. The bank loan stays in place, and a short term loan is made behind it.

AmountShare of value
Property value$2,000,000100%
Existing first mortgage (bank)$1,000,00050%
Second mortgage (this loan), maximum$600,00030%
Total debt$1,600,00080% total LVR
Equity buffer$400,00020%

The second-ranking lender is repaid after the bank. So what protects it is the $400,000 of equity sitting above all the debt. The property would need to lose more than 20% of its value, less sale costs and accrued interest on both loans, before the second mortgage’s capital was at risk.

Two honest points. First, the bank’s interest and costs keep accruing if a loan goes into default, which uses up part of the buffer; that is one reason the cap is set at 80% and not higher. Second, a buffer does not stop a default; it protects capital if one happens. Our guide to LVR for mortgage investors works through more scenarios.

Why would a borrower use a second mortgage?

From the lender’s side, a second mortgage usually reflects a practical choice by an established business owner. They have a bank loan on good terms that they don’t want to disturb, and they need capital for a few months: to settle a purchase, fund a business opportunity or bridge a timing gap. Leaving the bank loan in place and adding a short second-ranking loan is often faster and simpler than replacing everything.

For you, the question is not why they chose it, but whether the numbers work: the total LVR, the property, the borrower’s position and a credible exit within the 1 to 12 month term.

When does each position suit an investor?

A first mortgage suits you if you want the clearest priority and the whole value of the property standing behind your loan. It is the natural starting point for a new co-funder, and for SMSF trustees who want the simplest security to explain to their auditor.

A second mortgage suits you if you are comfortable relying on the total LVR and equity buffer rather than first ranking, and you want to widen the range of loans you can choose from. Because a second-ranking position carries more risk than a first on the same property, it is generally priced accordingly. The rate for each loan is set loan by loan and shown in its pack.

Many investors hold both over time. Spreading across first and second positions, different properties and different states is a sensible way to build diversification loan by loan.

What is a caveat, and how is it different?

A caveat is a notice lodged on a property’s title that records a claimed interest in the property. It stops other dealings from being registered without the caveator being notified, which gives the lender a strong hold over any attempt to sell or re-borrow against the property.

A caveat is not a registered mortgage. It does not, on its own, give the lender the same direct power of sale, so enforcing it usually relies on the loan documents and the courts. For that reason it is generally regarded as a weaker form of security than a registered mortgage.

Where a caveat is the security on a loan HomeSec offers, the loan pack says so clearly, and you are named on the caveat for your exact contribution. You can then decide whether that loan suits you. The glossary defines caveats, mortgagee in possession and other terms you will see in a pack.

What does HomeSec check before offering either position?

Every loan, first or second, is assessed against HomeSec’s 50-point due diligence checklist before it is offered to you. The same rules apply to both:

  • A maximum 80% LVR on residential property, counting all debt ranking ahead; lower on commercial property.
  • No development loans and no construction loans.
  • Short terms of 1 to 12 months.
  • No unusual properties, or anything that would take a long time to sell.
  • HomeSec’s own money in the same loan.

HomeSec knows property markets right across Australia, and both joint CEOs are involved in every loan decision. The full set is on our lending rules page, and the protections if a borrower does default are explained in risks and protections.

Frequently asked questions

What is a first mortgage investment?

A first mortgage investment is a loan secured by a mortgage that ranks first on a property's title. If the borrower defaults and the property is sold, the first mortgagee is repaid its principal, interest and costs before any later-ranking lender. With HomeSec you are named on the registered mortgage for your exact contribution, alongside HomeSec.

How is a second mortgage investment protected?

By the equity left after all the debt. HomeSec caps total borrowing, the first mortgage plus the second, at 80% of the property's value on residential property, and lower on commercial. That leaves at least a 20% buffer that must be used up by falls in value, costs and interest before the second-ranking lender's capital is at risk.

What does registered mean for a mortgage?

A registered mortgage is recorded on the property's title at the state land titles office. It is public, it ranks in the order it was registered, and it gives the lender the right to take possession and sell if the borrower defaults. With HomeSec, investors are named on the registered mortgage for their exact contribution.

Is a first mortgage always better than a second mortgage?

Not always. A first mortgage has priority, but a well-structured second mortgage behind a modest first mortgage can carry less total debt against the property than a first mortgage at a high LVR. What matters is the total LVR, the property, the borrower and the exit. The rate for each loan is set loan by loan and shown in its pack.

What is a caveat and how is it different from a mortgage?

A caveat is a notice lodged on a property's title that records a claimed interest and stops other dealings from being registered without the caveator being notified. It does not give the same direct power of sale as a registered mortgage, so enforcement usually relies on the loan documents and the courts. Where a caveat is the security, the loan pack says so.
