Investment Property Loans in Newcastle: A Simple Guide
29 June 2026 · The Newcastle Mortgage Broker
Thinking about buying a rental property around Newcastle? You might already be sitting on the deposit without knowing it.
Your home could hold the deposit
Many people buy their first investment property using the equity in the home they already own. Equity is the share of your home you truly own. It is the value of the home minus what you still owe the bank.
Lenders will usually let you borrow against your home up to about 80% of its value. The gap between that figure and your current loan is your usable equity. That money can become the deposit on a rental property.
If you want to start with the basics first, our home loans page is a good warm-up.
A worked example
Here is how usable equity often works in real life.
This does not mean Priya has $240,000 in cash. It means she may be able to access that amount as new borrowing, if her income and the lender’s checks stack up.
Interest-only vs principal and interest
Investment loans come in two main repayment styles.
With principal and interest (P&I), each repayment pays off some of the loan and some interest. The balance slowly shrinks.
With interest-only, you pay just the interest for a set time, often a few years. Repayments are lower during that period, but the loan amount does not drop. Some investors choose this to keep cash flow comfortable. The trade-off is you pay more interest over the life of the loan.
There is no single right answer. It depends on your goals, your cash flow and your tax position. Always check the tax side with your accountant, since the rules around investment property are their area, not ours.
How the loans are structured
Most investors keep their home loan and their investment loan separate, even when both are with the same lender. This keeps the numbers clean and makes life easier at tax time.
A common setup is a split or a second loan secured against your home for the deposit, plus a new loan for the investment property itself. How you arrange this matters, so it is worth planning before you sign anything.
If you ever refinance later, the way things were set up can affect your options. Our refinance page explains more.

Frequently asked questions
Can I really buy an investment property with no cash deposit?+
Sometimes the deposit can come from equity in your existing home instead of cash savings. You still need enough income and to pass the lender's checks, so it is best to confirm your situation with a broker first.
Is interest-only better than principal and interest for an investment loan?+
Neither is automatically better. Interest-only can ease cash flow now but usually costs more interest over time, so the right choice depends on your goals and your accountant's tax advice.
Will using my home as security put it at risk?+
Borrowing against your home means it is used as security, so it is important to make sure the repayments fit your budget. A broker can help you understand the numbers before you decide anything.
