Releasing Equity From Your Home

What home equity is, how much you may be able to access, and the smart and risky ways to use it, explained simply by an Adelaide mortgage broker.

Updated June 2026

Equity is the share of your home you actually own, the gap between what it is worth and what you still owe. As you pay your loan down and your property value rises, that equity grows, and you can often put it to work without selling. Releasing equity means refinancing or increasing your loan to draw part of that value as usable cash. Used well it can fund a renovation, an investment, or other goals at home loan rates rather than expensive personal debt. Used carelessly it simply adds long term debt you pay interest on, so it pays to go in clear eyed.

How much equity can you actually use?

Usable equity is not the same as your total equity. As a general guide, many lenders let you borrow up to 80 percent of your property value, then subtract what you still owe, and the difference is what you may be able to access without paying lenders mortgage insurance. The exact figure depends on the lender, the valuation and your borrowing capacity.

What people use released equity for

Lenders generally want to know the purpose, and some uses are easier to approve than others. Putting equity toward something that grows your position tends to sit better, with both the lender and your future self, than spending it on things that lose value.

The interest you pay on what you release

This is the part to be clear eyed about. Releasing equity is borrowing, so you pay interest on whatever you draw, usually spread over the remaining term of your loan, and your repayments may rise. A sum that feels small today can cost far more across twenty or thirty years of interest. It is a powerful tool when it funds something that builds your position, such as a value adding renovation or an investment, and an expensive one when it funds everyday spending.

How lenders assess an equity release

Accessing equity is not automatic. The lender reassesses your ability to repay the larger loan, orders a valuation of your property, and often asks what the funds are for. If your income or expenses have changed since you first borrowed, that can affect how much you are able to release. Going in with your paperwork ready makes the process smoother.

Equity release in retirement is different

For older homeowners, equity release can also mean a reverse mortgage or the government Home Equity Access Scheme, which work very differently to a standard loan increase and carry their own rules, costs and risks. If you are in or near retirement, treat this as a separate decision and get specific advice before acting.

Is releasing equity right for you?

The honest answer depends on what the money will do and what it will cost. If it funds something that adds value or income and you can comfortably carry the larger repayment, it can be a smart move. If it funds spending that disappears, the long run interest usually outweighs the short term convenience. Running your actual numbers first is the difference between a good decision and an expensive one.

Often you can avoid it by staying within 80 percent of your property value. If releasing equity pushes your loan above that level, lenders mortgage insurance may apply, which can add a meaningful cost.

Do I have to tell the lender what the money is for?

Usually yes. Lenders generally ask the purpose of the funds, and some purposes are easier to approve than others. Being clear about a sound use, such as renovating or investing, helps your application.

Does releasing equity increase my repayments?

It can. You are borrowing more, so unless you change the term or structure, your repayments usually rise to cover the larger balance and the interest charged on it.

Is releasing equity a good idea?

It depends entirely on what the funds do and what they cost. Equity put toward something that builds value or income can pay off, while equity spent on everyday costs tends to cost more in long run interest than it is worth.
