New Builds or Existing Properties: What’s the Smarter Investment?

With new investment rules in place, there is only one way investors should be looking when tossing up between new builds or existing properties.

At some point in every investor’s journey, one key decision comes up: Should I buy a new build or existing properties?

Old-school wisdom tends to favour existing properties - the thinking goes, “more land equals more capital gains.” But in today’s market? That mindset is costing investors real money.

Let’s cut through the noise and lay out exactly why new builds are dominating the investment landscape - and why existing homes might just be holding you back.

The Old Argument: Existing Homes = More Land = More Value

Sure, existing homes often come with a bigger backyard. But the truth is that capital growth isn’t tied to lawn size anymore.

The only property type that consistently underperforms long-term capital growth is apartments, not new builds. Standalone houses and townhouses (including brand-new ones) are performing just fine.

So the real question becomes: what’s the better vehicle for wealth-building?

The Game-Changers: Two Government Incentives Tipping the Scales Toward New Builds

1. Interest Deductibility
   

2. Lower Deposit Requirements
   

Let’s unpack these, because they significantly impact your bottom line.

1. Interest Deductibility = Better Tax Efficiency

This one’s a biggie.

New builds retain full interest deductibility, meaning you can deduct mortgage interest costs when calculating your taxable rental income.

• Lower taxable income
  

• Smaller tax bills
  

• Better cash flow
  

Compare that to existing properties, where interest deductibility is being phased out under current tax rules. That means higher taxable income and more tax.

Translation? Existing homes just became a lot more expensive to hold.

2. Lower Deposit Requirements = Greater Leverage

Investors buying new builds only need a 20% deposit. Existing homes? 30%.

Let’s say you’re eyeing a $650,000 property; this is the deposit you'd need:

• New build = $130,000 deposit
  

• Existing = $195,000 deposit
  

That’s a $65,000 difference, capital that could go toward another investment, renovations, or staying liquid.

In short, new builds let you do more with less.

Hidden Bonus: Lower Ongoing Costs

New builds aren’t just about incentives; they’re also smarter to own.

• Built to Healthy Homes standards
  

• 10-year builder warranties
  

• Minimal maintenance required
  

Compare that to older homes: leaky roofs, dodgy wiring, retrofitting insulation, and surprise repairs that eat your returns. One roof repair could set you back upwards of $20k, which hampers your cashflow for a decade.

So, Which Should You Choose?

Unless you’re a full-time flipper or renovating specialist, new builds are the better move for most investors.

Why?

• Better cash flow
  

• Lower deposits
  

• Tax efficiency
  

• Lower upkeep
  

• Strong capital gains (non-apartment stock)
  

The numbers, the policies, and the real-world experience all point in one direction.

Final Word: It’s Time to Ditch the “Old is Better” Mentality

The property game has changed, and savvy investors are adapting. New builds aren’t just easier to own, they’re more scalable, less risky, and designed for modern investing.
