Client Snapshot
A couple in their early 30s, living in Brisbane with their young children, recently decided to take their first step into property investment. Both are employed full-time and in the 37% tax bracket. Their goal is clear: grow long-term wealth through smart real estate investing while keeping cash flow close to neutral.
They wanted to balance capital growth potential with tax efficiency and strong rental yield â all while making sure their first investment wouldnât put pressure on their day-to-day finances.
Client Case Study: First Investment â Duplex in North Tamworth
Why North Tamworth?
North Tamworth, NSW, is a growing regional hub with reliable infrastructure, strong rental demand, and a 10-year average capital growth rate of 7.3%. The location made sense from both a cash flow and equity-building perspective. After market analysis and feasibility modelling, they chose a full turnkey duplex â a property that can generate two rental incomes, reduce vacancy risk, and enhance borrowing power for future investments.

Final Thoughts
This case study shows how a well-chosen regional duplex can tick all the boxes for first-time investors:
â Strong capital growth
â Tax-effective holding via depreciation
â Positive cash flow potential â especially with 80% LVR or falling rates
â Reliable yield over 5% in a growing market
For this Brisbane couple, itâs not just about one property. This is the first step in a long-term strategy â and theyâve set themselves up smart.
