Building a Property Portfolio

The constraint on building a property portfolio isn't usually courage or ideas — it's serviceability. Lenders assess your borrowing capacity based on income vs total debt commitments. As you add investment properties, each new property's rental income (assessed at ~75–80% by lenders) is counted against its new interest commitment. If the property is negatively geared, it reduces your serviceability for the next purchase. This is why the sequencing matters. Buying multiple negatively geared properties quickly exhausts borrowing capacity. Some investors alternate: one negatively geared property in a growth corridor, then one positively geared or neutral property to restore serviceability, then repeat. Others wait for equity to grow before accessing it via refinancing to fund the next deposit. The equity extraction strategy works like this: Property 1 bought for $700,000, now worth $900,000. Bank will lend 80% of $900,000 = $720,000. Existing loan: $560,000. Available equity: $160,000. This becomes a deposit for Property 2. No cash out of pocket required — the growth in Property 1 funds the next purchase.

Once you're building a portfolio seriously, a buyer's agent pays for itself. A good buyer's agent (1–2.5% of purchase price) provides access to off-market listings, removes emotion from the process, negotiates professionally, and has suburb-level data you can't access as a retail buyer. In Brisbane's competitive market, off-market access matters. The best properties in good suburbs often sell before hitting realestate.com.au. An agent with strong local relationships can present your offer to vendors before the property is publicly listed. For SE Queensland specifically, look for buyer's agents who focus on investment (not just helping people find their dream home) and can demonstrate data-driven suburb selection. Ask for their average purchase price vs suburb median and their client's average capital growth performance over 5 years. Firms like Propertyology or Empower Wealth are known for a data-driven investment approach.
