As discussed on The Property Nerds with Adrian and Jack (Fouracre Finance).

We all love saying “property is the game,” but the truth is property is the game of finance. In this episode recap, Adrian and Jack from Fouracre Finance unpack the three most common finance mistakes they see — plus a bonus tip that could save you six figures over a cycle.


Before the mistakes: two 2025 shifts investors can’t ignore

1) Rate cuts aren’t automatically “good news” — watch the pricing games

When the RBA cuts, many lenders adjust discretionary discounts for new customers. If you wait for a cut, your “special pricing” can quietly shrink, leaving you no better off than acting earlier. In a variable-rate world, securing a strong discount and settling often beats waiting for headlines.

Investor tip: If you’ve got a sharp discount approved, consider settling before a cut so the reduction flows through on top of your locked-in pricing.

2) First Home Guarantee expansion from

The federal Home Guarantee Scheme has expanded with unlimited places, no income caps, and higher property price caps. Eligible first-home buyers can purchase with as little as a 5% deposit and avoid Lenders Mortgage Insurance (LMI). NSW also retains generous stamp duty relief for many FHBs, which compounds the effect.

Investor tip: Expect a front-loaded demand pop. Early movers tend to capture more of the uplift when policies expand capacity and reduce friction.


Mistake #1: Treating one lender’s “no” as the final answer

Every lender services differently. A decline with Lender A can be an approval with Lender B thanks to policy quirks, income verification rules, shading of variable pay, or handling of existing debts.

  • What to do: Get a genuine second opinion from a broker who works across multiple lenders.
  • Red flags that need nuance, not surrender: recent credit enquiries, complex income, multiple debts, or niche trust/company structures.

Good process beats “computer says no.” Double-check before you down tools on a purchase or refinance.

Mistake #2: Cross-collateralising your properties “for convenience”

Cross-collateralisation ties multiple properties to one lending arrangement. It looks tidy on paper, but:

  • Partial discharge pain: Selling one property can trigger reassessment across the whole bundle — lenders can force debt reshuffles, extra valuations, or even block the release if the rest doesn’t re-service cleanly.
  • Refi friction: Moving one loan becomes harder when everything is knotted together.
  • Tax complexity: Messy debt apportionment can create problems for interest deductibility.

Best practice: Keep securities uncrossed (stand-alone loans), maintain clean splits, and accurately track what each loan funded.

Mistake #3: Having a property strategy but no finance strategy

Most investors plan purchases; fewer plan their funding sequence. The result is hitting borrowing walls early.

Think in phases:

  1. Accumulation: Use policy-friendly lenders and structures to add quality assets and grow equity.
  2. Cash-flow gear-shift: Harvest equity (via strategic sales or recycling) and step into higher-yield assets (e.g., commercial) using fit-for-purpose structures (e.g., trusts) to stabilise cash flow.
  3. Reset & repeat: With stronger income, re-enter residential accumulation in a separate, clean structure.

Deliberate sequencing can compress timelines to your target portfolio size and income.

Bonus mistake: Selling just because your market finally moved

After flat years, a quick surge tempts many to sell “while it’s up.” But cycles end when fundamentals change, not simply because a chart rose. In robust capitals, an extra year of hold time can turn “below-average” into “at least average.” Be data-led, not relief-led.
