For many clients, particularly later in life, property is their most significant asset. Unfortunately, it’s often not a source of liquidity when you need it. As lending products have evolved, reverse mortgages have become more popular as a solution for unlocking liquidity.
Reverse mortgages are significantly different to standard mortgages. The distinction is not just in how the product is structured but also in the potential legal and financial consequence. Mortgage holders should pay close attention to risk allocation, long term equity erosion, and the level of borrower protection.

A standard mortgage works as most expect: the borrower receives funds and is required to make periodic repayments, whether principal and interest, or interest only, with the loan reducing over time. Failure to make repayments may lead to default. This is what is referred to as a ‘forward-looking’ credit product.
A reverse mortgage operates in the opposite direction, a ‘backward-looking’ product. The borrower, typically over 60, accesses the equity in their home, without any requirement to make ongoing repayments. Instead, interest is gradually added to the balance of the loan, and the loan is only repaid when a certain event reaches maturity. This event could be the sale of a property, permanent vacation of a property or at the time of the borrower’s death.
Most clients seek out a reverse mortgage due to a requirement for extra liquidity rather than a need for credit.
Common drivers we see include:
Reverse mortgages are obviously appealing as there are ‘no repayments’ so to speak and because the financial impact is deferred. However, from a legal perspective, that deferral can hide both long term costs and risks.
Standard mortgage: enforceable repayment schedule, failure triggers default remedies
Reverse mortgage: no periodic repayments, lender relies on property value and accrued debt
You may think no repayments is low risk however, in reality, it transfers risk into the future via compounding interest.
Reverse mortgages typically involve higher interest rates than standard residential lending, with interest gradually capitalising over time.
This creates exponential growth in the debt. Over extended periods, the loan balance can materially erode, or entirely consume, the borrower’s equity.
This is the most critical financial risk.
Unlike a standard mortgage, where equity generally increases over time, a reverse mortgage reduces equity.
This has downstream consequences including::
We’ve seen firsthand situations where mortgage holders have underestimated this impact, particularly where loans run for 10 to 20 years.
Reverse mortgages are typically governed by conservative loans to value ratios, which increases as the borrower ages. While this mitigates lender risk, it also means:
Even where a reverse mortgage fully complies with the National Consumer Credit Protection Act 2009 (Cth) and associated protections, including the no negative equity guarantee under section 86A, several provisions warrant close legal attention.
Some reverse mortgage products include break costs or deferred establishment fees if the loan is repaid early. This can occur if the property is sold earlier than anticipated or as a result of refinancing.
These fees and charges can be significant, and borrowers may not consider such outcomes when signing. As circumstances can change, we always recommend our clients consider the worst-case scenario when reviewing agreements.
As there are no periodic repayments in a reverse mortgage, default provisions often hinge on non-financial obligations, including:
Clients may not consider these provisions before signing and these triggers can significantly accelerate the loan and force sale, a highly adverse outcome for vulnerable borrowers.
Lenders often retain discretion to require updated valuations, limit further drawdowns, and reassess loan conditions based on property condition or market movement.
The effect of compounding interest can be severe.
Clients often fail to appreciate how quickly debt escalates, the sensitivity to interest rate increases, (which may be impacted by economic and geopolitical factors out of their control), and the long-term erosion of equity.
A lack of clear financial modelling at the outset is a recurring issue.
See examples below of our reverse mortgage to home equity calculator to see the results when considering various scenarios.
Reverse mortgages ordinarily require the borrower to reside in the property as their principal place of residence. Extended absences such as moving into an aged care facility may trigger repayment obligations, and clients can be caught out as a result of unexpected health concerns. This can create pressure at the worst possible time, when the borrower is most vulnerable.
Upon a maturity event, lenders generally have rights to take possession and sell the property.
Reverse mortgages in Australia are regulated under the National Consumer Credit Protection Act 2009 (Cth) and the National Credit Code. The Australian Securities and Investments Commission (ASIC) also publishes regulatory guides in respect of misleading conduct, consumer protection and enforcement options.
Key protections include mandatory projections illustrating long term impact, requirements around responsible lending, and the no negative equity guarantee.
While these protections go some way to protect the borrower, they do not eliminate commercial risk, particularly around equity erosion.
Before committing to a reverse mortgage, we always recommend reviewing and addressing the following areas:
Reverse mortgages aren’t inherently a poor choice. For some clients, they provide a legitimate mechanism to unlock equity and maintain financial independence.
However, they are not a soft form of lending. They are a deferred debt instrument with compounding consequences.
Reverse mortgages require an understanding from the client about suitability and possible long-term outcomes. A good lawyer will help their client understand what they are giving up in exchange for immediate liquidity.
