What is a mortgage fund, and how does a mortgage trust pay investors?

A mortgage fund is a managed investment, usually a unit trust, that pools money from many investors and lends it to borrowers against registered mortgages over property. You hold units in the fund, not a particular loan. The interest borrowers pay, less the manager’s fees and costs, flows back to unit holders as income.

That is the whole idea, and it is simple enough. What decides whether a fund suits you is in the fine print: withdrawal rights, who values the properties, and what the fund actually lends against. HomeSec Business Finance, an Australian private lender founded in 2004, takes a different route (wholesale investors co-fund individual loans and are named on the mortgage), so we will compare the two honestly at the end.

How does a mortgage fund actually work?

Money comes in from investors and goes out again as loans. The manager (often called a responsible entity or trustee) assesses borrowers, sets the loan-to-value ratio (LVR) limits, registers a mortgage over each property and collects the repayments.

The cash flow has four steps:

1. Investors subscribe for units. Their money joins the pool.
2. The manager lends the pool to many borrowers, typically against residential, commercial or land security.
3. Borrowers pay interest and fees, and eventually repay principal.
4. The fund pays distributions to unit holders after deducting management fees, performance fees, loan costs and any provisions for loans in trouble.

Your return is the average outcome across the whole portfolio. One strong loan and one troubled loan blend together, which smooths the ride and also means you share in losses on loans you never saw.

What is a mortgage trust, and are there different types?

“Mortgage trust”, “mortgage investment trust” and “private mortgage fund” all describe the same family. The label tells you little; the structure tells you a lot. Four variations matter:

ASIC’s RG 45 sets disclosure benchmarks for unlisted mortgage schemes offered to retail investors. Funds sold only to wholesale investors are not held to that disclosure regime, so the due diligence falls on you.

Why can a mortgage fund freeze your money?

A mortgage fund promises something its assets cannot always deliver: the ability to withdraw, backed by loans that take months to repay. A loan secured by a house cannot be sold in a week at full value. When many investors ask for their money at once, the cash runs out before the requests do.

The fund’s constitution usually lets the manager respond by limiting, delaying or suspending withdrawals. This has happened repeatedly:

• 2008: after the bank deposit guarantee arrived, a run of pooled funds shut their gates. Challenger Howard’s fund, near $2.9 billion, was the largest.
• 2013: LM’s First Mortgage Income Fund (about $1 billion at its peak) had been locked since the GFC and went into administration with the manager.
• 2026: Centuria Bass paused withdrawals on two credit funds in August, and other managers capped or suspended theirs. Our redemption freeze explainer has the detail.

A freeze does not mean the loans are bad. It means the fund’s liquidity promise and its loan book are mismatched. For the investor the practical result is the same: your capital is inaccessible, on someone else’s timetable. If that is your worry, read can I get my money out of a mortgage fund.

Who values the properties, and why does it matter?

A fund’s reported performance depends on what the manager says its loans are worth. If a loan is in arrears and the property is valued optimistically, the fund can keep paying distributions that look healthy while the real position is weaker.

ASIC’s November 2025 surveillance of 28 private credit funds (REP 820) found problems in exactly these areas:

• borrower fees kept by managers without clear disclosure;
• weak conflicts-of-interest policies;
• the same committee approving loans and later assessing their value;
• side letters giving some investors better redemption terms than others.

On 22 September 2026 ASIC told the sector to prepare for enforcement action, noting that of the 28 funds reviewed only four disclosed the rates charged to borrowers and only two wholesale funds had stress-tested their liquidity. Those two results are worth remembering when a brochure says “rigorous”.

What does a mortgage fund invest in?

This is where funds differ most, and it is the line most fact sheets blur. A fund holding short term first mortgages on completed homes at moderate LVRs is a very different thing from one lending to developers on land and unsold stock.

ASIC’s REP 814 put the Australian private credit market at roughly $200 billion in 2025, and more than half of it is real-estate debt, much of it lent to developers. When the Bathla Group entered voluntary administration in August 2026, with roughly $3.2 billion of liabilities mostly owed to private credit, the exposure was largely construction, land and unsold-stock loans, as covered in our piece on the Bathla collapse.

Ask any manager for the split between development, construction and completed-property loans, the weighted average LVR, the share of loans in arrears or extended, and how many loans are to related parties.

Are mortgage funds a good investment?

For some investors, yes. A fund can suit someone who wants built-in diversification, a modest starting amount and no loan-by-loan decisions. It can also pay well above a term deposit’s single-digit return. The question is whether you are paid enough for what you give up.

The Financial Claims Scheme row is the one people overlook. Moneysmart is clear that private credit is not covered by the scheme, so a fund’s protection rests on its security, its lending rules and its manager rather than the government.

How is direct co-funding different from a mortgage fund?

HomeSec does not run a pool. Each loan stands alone. HomeSec weighs it against a 50-point checklist, emails the pack, and you say yes or no, choosing your own amount (from $100,000 up to several million dollars). If you say yes, your name goes on the registered mortgage (or caveat) for exactly what you put in, next to HomeSec’s.

Every loan offered to investors carries HomeSec’s own capital too, frequently split evenly. Terms run from 1 to 12 months against first and second mortgages over Australian real estate, with a ceiling of 80% LVR on residential property and lower on commercial. We do not write development or construction loans at all. Interest and principal are paid to your own account rather than through us, and if you need to leave early, HomeSec buys your share out.

Illustrative example. An investor puts $250,000 into one loan secured against a completed property. They read the pack, see the property, the LVR and the exit, and are named on the mortgage for that $250,000. At maturity the principal and interest return to their own account. A second investor in a pooled fund with the same $250,000 holds units; they see a monthly report and cannot say which properties their money sits against.

The trade-off is that you build your own diversification loan by loan and you must be wholesale or sophisticated. See direct mortgage investment vs pooled funds for the full comparison and how it works for each step. If it helps to see what a loan pack looks like before deciding, you can ask for a sample loan pack.

What should you check before putting money in any mortgage fund?

Use this list on any fund, including ours if we ever launched one:

• Withdrawal terms: frequency, notice period, limits, and when the manager may suspend.
• Cash held: how much sits in liquid assets compared with what investors can ask for.
• Asset mix: development and construction share, LVR, arrears.
• Valuations: who does them, how often, and whether they are independent.
• Fees: management, performance, borrower fees retained, and any related-party arrangements.
• Manager’s own money: whether it sits in the same loans on the same terms.
• Side letters: whether any investor gets better redemption terms.

Our longer list of questions to ask a private credit manager goes deeper, and the glossary explains the terms.

Would you rather choose the loan yourself?

A mortgage fund asks you to trust a manager’s choices and a withdrawal clause. Direct co-funding hands both back to you: the loan, the pack, the decision and the name on the mortgage, with HomeSec’s own money in the same loan. If that is the kind of control you have been looking for, register your interest and our Funding Manager will walk you through the next loan pack and what qualifies you as a wholesale or sophisticated investor.
