How interest-only loans work:
During the interest-only period, you only pay the interest charges. Your loan balance stays the same. After this period ends, your repayments increase significantly because you must pay both principal and interest over the remaining term.
Important: Interest-only loans typically cost more overall than principal and interest loans because you pay interest on the full loan amount for longer.

Do I have to come into an office to apply?
Not at all! We offer phone, video, and online appointments — perfect if you're in a rural spot or juggling a busy schedule.
Do I need a finance broker?
Whether you need a finance broker depends on your financial situation and comfort level with the borrowing process. If you have a good understanding of financial products and feel confident negotiating with lenders, you may not need a broker. However, if you're unfamiliar with the process or have specific needs, a broker can provide valuable assistance.
Ultimately, the decision should be based on your individual circumstances and preferences.

How do finance brokers get paid?
Finance brokers typically earn their income through commissions paid by lenders when a loan is successfully arranged. This means that their services are often free for clients, as the lender covers the broker's fees. However, some brokers may charge a fee directly to clients for their services, especially if they provide additional consulting or financial planning.
It's important for clients to clarify the payment structure with their broker upfront to avoid any surprises later in the process.
