Understanding Mortgage Funds at a Glance
A mortgage fund pools investor capital and lends it to borrowers, with the loans secured by mortgages over property. Investors are not buying a property, and they are not buying a mortgage directly. They are investing in units of a managed investment scheme whose assets are loans, cash, and related receivables.
Mortgage fund returns come from interest income and borrower fees, not from rent or property price appreciation. That makes them fundamentally different from property funds, REITs, and direct property.
It is also important to understand why mortgage funds exist. In Australia, non-bank lenders are a permanent part of the lending ecosystem. Securitisation is a major source of funding for non-bank lenders. The Reserve Bank of Australia has noted that residential mortgage-backed securities (RMBS) make up an estimated three-quarters of funding for Australian non-bank mortgage lenders.
The Australian Finance Industry Association (AFIA) notes that registered non-bank lenders’ total stock of loans amounted to $72.2 billion, representing 3% of housing finance nationally.
The practical implication is that a large, institutional-grade market exists for property-secured lending outside the major banks, and mortgage funds are an important channel that provides investors access to this segment.
How Mortgage Funds Generate Returns
Mortgage funds generate returns primarily through interest paid by borrowers, plus fees such as establishment fees and, in some cases, ongoing borrower fees.
The typical flow works like this: Borrower pays interest and fees → the fund receives the cash flow → the manager deducts fees and operating costs → investors receive distributions.
Several drivers shape mortgage fund returns:
1. Loan risk.
Higher-risk loans generally command higher interest rates, but they also increase the chance of arrears, defaults, restructures, and potential capital losses.
2. Loan type.
First mortgages, second mortgages, construction loans, development loans, commercial mortgages, and bridging loans all have different risk mechanics and different sensitivity to housing turnover, building costs, and refinancing conditions.
3. Borrower profile and exit strategy.
A short bridging loan with a clear sale settlement timetable behaves differently from a multi-stage construction loan dependent on approvals, contractor performance, and end-buyer demand.
4. Fees.
Management fees, performance fees, and other operating costs reduce a fund’s net returns. This is why investors should focus on net returns and risk disclosures, rather than headline borrower rates.
5. The broader lending cycle.
Credit conditions, property market liquidity, and refinancing availability can all affect default frequency and recovery outcomes. The Reserve Bank of Australia has repeatedly emphasised that arrears are concentrated among more leveraged borrowers, and that loan arrears remain highest among highly leveraged and lower-income households.
Returns are not guaranteed. Income depends on borrower repayments and the performance of the fund’s loan book.
The Loan Portfolio Behind Mortgage Funds
Mortgage funds are defined by what sits inside the loan book. Understanding common loan types helps investors interpret disclosure documents and compare funds consistently.
First Mortgages
A first mortgage is a loan secured by a first-ranking claim over a property. If a borrower defaults, the first mortgage lender is repaid before any other secured creditors. First mortgages are used for purchases, refinances, and equity release. They are often viewed as lower risk due to their priority, but they still carry risk from borrower default, valuation inaccuracies, and falling property prices.
Second Mortgages
A second mortgage sits behind a first mortgage on the same property. In a default, second mortgage lenders are repaid only after the first mortgage has been repaid in full. These loans tend to pay higher interest to compensate for their subordinate position. They are more exposed to adverse property price moves because recovery depends on sale proceeds exceeding the first mortgage balance.
Construction Loans
Construction loans fund building works. Funds are commonly drawn down in stages through progress payments. Risks include delays, cost overruns, builder insolvency, regulatory issues, and end-buyer demand. Some construction loans include capitalised interest, where interest accrues and is paid at completion rather than being paid monthly. That can make distributions less predictable if the loan book leans heavily towards capitalised interest structures.
Development Loans
Development loans can fund land acquisition, subdivision, or redevelopment. They typically carry higher planning and market-timing risk than vanilla first mortgages. A project that is viable under one set of prices, construction costs, and lending conditions can become stressed when those assumptions shift.
Commercial Mortgages
Commercial loans are secured against income-producing assets such as industrial property, offices, retail assets, and specialised property. Risk depends on tenant quality, vacancy, lease terms, and sector conditions.
Bridging Finance
Bridging loans are short-term loans designed to bridge a timing gap, such as a purchase settlement before a sale, or a refinancing delay. Bridging finance can be lower risk when exit pathways are clear, but it can become higher risk when markets are illiquid or when settlements fall through.
Most mortgage funds mix loan types to balance yield and risk. Diversification reduces single-borrower exposure, but it does not remove systemic risk.
Key Features that Define a Mortgage Fund
Mortgage funds can look similar on the surface. Most talk about income and security.
The important differences tend to show up in the details:
Loan-to-Value Ratio (LVR)
LVR measures the loan balance relative to the property value. Lower LVRs provide a larger equity buffer, which can reduce loss severity if a borrower defaults. Higher LVR loans may earn more interest, but they are more sensitive to valuation changes.
As a point of market context, APRA’s authorised deposit-taking institution mortgage exposure statistics for September 2025 show that loans with LVRs of 80% or higher represented 16.8% of ADI residential mortgage exposures.
Security Position & Collateral Quality
Security refers to the lender’s legal claim over the asset. First-ranking mortgages generally have stronger recovery priority than second mortgages. Collateral quality varies significantly across residential, commercial, industrial, and land, and also by location and market liquidity.
Independent valuations matter because property valuations can lag market conditions, particularly in stressed environments.
Liquidity Mechanism
Mortgage funds are often not liquid on demand. Liquidity depends on cash buffers, borrower repayments, loan run-off, and the manager’s redemption policy. Many funds have notice periods, withdrawal windows, redemption caps, or queues, and may suspend withdrawals during periods of market stress.
ASIC’s Regulatory Guide 45 sets out ASIC’s benchmarks and disclosure principles to help retail investors understand and assess unlisted mortgage schemes, including disclosure on liquidity and withdrawal arrangements.
Fund Structure: Pooled vs Contributory
This structural distinction matters.
Pooled funds combine investor capital into a diversified portfolio. Investors gain diversification but do not control loan selection.
Contributory funds allow investors to invest in specific loans. This increases control but concentrates risk. It also increases the importance of investor skill in assessing borrower quality, valuation assumptions, and exit pathways.
ASIC explicitly distinguishes between pooled and contributory schemes in the context of mortgage schemes.
Types of Mortgage Funds in Australia
This section explains the main mortgage fund models typically available in Australia. The names may vary by issuer, but the underlying structures tend to cluster into a handful of categories.
Pooled Mortgage Funds
Pooled mortgage funds aggregate investor capital into a single portfolio that is diversified across many individual loans. Rather than being exposed to the outcome of one borrower, investors participate in the performance of the entire loan book. Risk is therefore spread across multiple properties, borrowers, and regions, although the overall risk profile still depends heavily on factors such as loan-to-value ratios, borrower quality, loan purpose, and underwriting standards. Returns reflect the blended performance of the portfolio rather than any single loan, and liquidity is determined by a combination of cash buffers, scheduled loan repayments, and the fund’s redemption policy.
An example of a pooled portfolio approach is the PMAC Trust Pooled Mortgage Retail Feeder Fund.
Contributory Mortgage Funds
Contributory mortgage funds operate on a more loan-specific basis, allowing investors to select individual loans to fund rather than investing in a diversified pool. This structure provides greater transparency and direct linkage between risk and return, but it also introduces higher concentration risk unless investors actively diversify across multiple loans. Returns are tied to the interest rate and performance of the selected loan, and capital is generally illiquid until the loan is repaid or refinanced.
An example of a contributory-style fund is the GPS Invest Select Fund.
First Mortgage Income Funds
First mortgage income funds focus primarily on loans secured by first-ranking mortgages, meaning they sit at the top of the capital structure in the event of borrower default. This senior position typically reduces loss severity compared with subordinated or mezzanine lending, although investors remain exposed to credit risk and property market conditions. Returns from first mortgage funds are often more moderate than higher-risk strategies, reflecting their senior security position. Liquidity varies by fund and is governed by redemption terms and portfolio cash flow.
Examples of first-mortgage-focused funds include the ASCF Select Income Fund and the CFMG Monthly Income Fund.
Mixed Mortgage Funds
Mixed mortgage funds blend first mortgages with higher-yielding segments such as second mortgages, construction loans, development finance, or commercial property lending. This diversified approach allows fund managers to target higher overall returns, but it also means the risk profile can shift over time as the portfolio mix changes. Returns may therefore be less predictable than those of first-mortgage-only funds, and liquidity depends on both the redemption policy and the extent to which underlying loans amortise or repay on schedule. These funds are often positioned as a middle ground between conservative income strategies and higher-risk private credit offerings.
Wholesale Mortgage Funds
Wholesale mortgage funds are typically available only to wholesale or sophisticated investors under the Corporations Act definitions. These funds may pursue larger, more complex, or higher-risk lending strategies, including higher loan concentrations, bespoke transactions, or specialised property sectors. As a result, risk can be higher and more nuanced, with greater reliance on manager expertise and structuring. Target returns are often higher than retail mortgage funds, but predictability and liquidity are usually more limited.
Examples include the CPF Property Debt Fund and the Banner Wholesale Real Estate Credit Fund.
Benefits of Mortgage Funds – When They Work Well
Mortgage funds can deliver several potential benefits when the underlying loan book is well underwritten and the liquidity policy matches the asset profile:
Income potential is the primary attraction.
Many mortgage funds distribute monthly or quarterly income sourced from borrower interest.
Diversification.
Pooled funds generally spread their loan exposure across many borrowers, projects, and property types.
Professional management.
Underwriting, loan servicing, covenant monitoring, and enforcement require specialist capability from the managers.
Access to hard-to-access markets.
Mortgage funds can also provide access to private credit segments that have expanded as non-bank lending has grown.
These benefits should always be read alongside the balancing factors. Income depends on borrower repayments. Diversification reduces but does not eliminate risk. Professional management improves oversight but does not guarantee outcomes.
Risks & Real-World Considerations
Awareness of the risks particularly matters because mortgage funds are often marketed with language that focuses on security and income. In practice, the primary risk is not whether the underlying property exists, but whether a fund’s loans can be realised, at what price, and in what timeframe.
Default & Arrears Risk
Arrears occur when borrowers fall behind on scheduled payments. Defaults occur when borrowers breach terms and the lender enforces rights. A default process can be slow, particularly if the property must be sold in a weak market or if there are legal disputes.
Market-level arrears data provides useful context. APRA’s September 2025 ADI mortgage statistics show that loans 30 to 89 days past due represented 0.47% of ADI residential mortgage exposures.
Liquidity Risk
Liquidity is often the most misunderstood risk.
Mortgage funds hold loans, and loans are not cash. If many investors request redemptions at once, the fund may have to defer, cap, or suspend withdrawals.
ASIC’s RG45 guidance is explicit that investors should be able to understand withdrawal arrangements and liquidity practices through benchmark disclosure.
Valuation Risk
Unlisted funds often have unit prices that appear stable. This can reflect valuation cycles rather than real-time market repricing. Property valuations can lag, and loan impairments can emerge abruptly when projects run into trouble.
Concentration Risk
Concentration can arise via geography, property type, borrower, or a single project. Contributory structures are inherently more concentrated unless investors deliberately diversify across multiple loans.
Interest Rate & Refinancing Risk
Higher rates can increase borrower stress and reduce refinancing options. That is one reason regulators focus on high-risk lending pockets.
Hence, APRA will implement a cap from February 2026 limiting banks to issuing only up to 20% of new home loans with debt-to-income ratios of six times or higher.
Manager & Governance Risk
Underwriting quality varies. Portfolio transparency varies. Related-party lending policies vary.
In mortgage funds, manager discipline is not a nice-to-have. It is the core risk-control variable.
How to Assess a Mortgage Fund Before Investing
A useful comparison framework focuses on what can be measured and what can be verified.
1. Transparency & Reporting
Look for clear disclosure on portfolio composition, loan types, geographic exposure, average and maximum LVRs, valuation practices, and related-party policies.
ASIC’s RG45 exists because consistent disclosure is essential for investors assessing mortgage schemes.
2. Arrears & Default Metrics
Arrears data is a leading signal, but it is not a prediction. Investors should look for consistent reporting of arrears, impaired loans, and realised losses.
3. Underwriting Quality
Underwriting quality is reflected in process and outcomes: valuation standards, borrower assessment, covenants, monitoring, and recovery experience.
4. Fee Structure
Fees reduce net yield. Hence, investors should understand management fees, performance fees, and any establishment or withdrawal costs prior to investing.
5. Liquidity Terms
Assess notice periods, redemption frequency, withdrawal caps, and the circumstances in which redemptions can be deferred or frozen.
6. Portfolio Composition
Understand the weighting to first mortgages versus subordinated lending and development exposure.
A high headline yield can be a clue to higher underlying risk.
Mortgage Fund Comparison Checklist
Here’s a checklist to help compare mortgage funds:
Comparing Mortgage Funds with Alternative Income Investments
Mortgage funds are often evaluated alongside other income options. The right comparison focuses on asset backing, liquidity, volatility, and the source of income. The table below compares mortgage funds with other common income investments available to Australian investors, including term deposits, bond funds, and property funds
Mortgage funds can be attractive when investors want income exposure tied to secured lending rather than listed market pricing. The trade-off is that liquidity is often constrained, and performance depends on underwriting and recovery capability.
Mortgage Funds vs Direct Mortgage Lending
The following comparison outlines the key differences between investing in Australian mortgage funds versus direct mortgage lending
The key takeaway is that direct lending requires the investor to assess valuations, borrower financials, legal documentation, and enforcement pathways. Mortgage funds trade some control for diversification and professional infrastructure.
Taxation & Regulatory Oversight
Mortgage funds are generally structured as managed investment schemes or trusts. Distributions are typically assessable and can include different tax components depending on the fund’s structure and activities.
The ATO notes that managed fund distributions can include components such as capital gains that investors must include in their tax return.
Cost base adjustments can also arise under certain trust regimes, including AMIT rules, depending on the fund’s tax profile and distribution components.
Mortgage funds offered to retail investors are subject to ASIC oversight. ASIC’s RG45 sets out benchmarks and disclosure principles for improved disclosure, including liquidity, loan portfolio, diversification, valuation, and related-party lending.
This is general information only and is not tax advice.
Common Misconceptions about Mortgage Funds
Here are some common misconceptions about mortgage funds:
Market Trends Shaping Mortgage Fund Investing
Mortgage funds exist inside a broader housing finance and credit environment.
ABS lending indicators show that in the September quarter 2025 the total number of new loan commitments for dwellings rose 6.4% and the value rose 9.6%.
Non-bank lenders remain a structurally growing part of the lending environment. The RBA has highlighted the importance of securitisation funding for non-banks, including the role of RMBS in their funding stack.
Regulatory focus is evolving. APRA’s planned DTI cap from February 2026 reflects a desire to limit the build-up of higher-risk household leverage in new lending flows.
For investors, the key takeaway is that mortgage funds should be assessed as credit investments first, and as property investments second.
