MORTGAGE YEARS
Shorter term, higher payments: 15 year mortgage advantage
A 15-year loan speeds up your path to owning your home outright. Monthly repayments are higher, but you save significantly on interest and build equity much faster. It’s a choice focused on long-term wealth, ideal for borrowers comfortable with a more demanding monthly commitment. Benefits of a 15-year term:
Much lower lifetime interest
Rapid equity growth
Encourages financial discipline
Sometimes eligible for slightly lower rates
This option suits borrowers with stable income and a priority of being debt-free sooner. HeyNest can connect you with a broker who models these repayments based on your financial situation.

Maximizing budget flexibility with a 30 year mortgage
A 30-year loan offers lower required repayments and greater monthly flexibility. It’s the more common choice in Australia because it leaves room for other financial goals such as investing or saving. Why borrowers choose a 30-year term:
Lower monthly payments
More room for other expenses or investments
Debt becomes easier to manage over time with inflation
Freedom to make extra payments without increasing your required amount
This option doesn’t restrict you from paying the loan off faster, it simply gives you flexibility. A HeyNest broker can help structure a loan that allows fee-free extra repayments.

Which mortgage term is right for you?
Choosing between a 15-year and 30-year mortgage depends on your lifestyle, income reliability and long-term goals. There’s no single best choice, only the best fit. How to decide:
Can you comfortably afford a higher repayment without straining your budget?
Do you value lower total cost (15-year) or greater cash-flow flexibility (30-year)?
Would a strategy of taking a 30-year loan but paying extra give you both security and savings?
A HeyNest-connected broker can compare both options across lenders and help tailor a strategy that matches your financial priorities, whether you prefer flexibility, faster payoff or a mix of both.

Frequently asked questions
Do most Australians choose a 15 or 30-year mortgage?
The 30-year mortgage is far more common due to its lower monthly payments and greater cash-flow flexibility.
Can I switch from a 30-year to a 15-year mortgage later?
Yes, this is possible through refinancing, though it involves a new application process and potentially new fees.
Does a 15-year mortgage usually have a lower interest rate?
Often, yes. Lenders typically offer a slightly lower interest rate on 15-year terms because the loan is less risky for them.
