The most expensive property mistake is buying before building the strategy around the purchase. In episode 92 of Finance This, Property That, Dion sits down with buyer's agent Jessica Giandomenico from Vesta Buyers Agency to unpack why the purchase itself is the easy part, and where investors actually lose money.

The conversation covers Jessica's first year building Vesta, and lands quickly on the shared observation from both sides of the table: most investors start too late. The strategy work that should precede an offer usually gets attempted after the contract is signed, when the options have already narrowed.

Why must the buyer's agent and the finance strategist work together?

Because each protects the other's work. The finance strategy determines what the client can actually settle, in what structure and on what timeline. The buyer's agent finds and negotiates the asset that fits the plan. When the two operate in silos, contracts get signed that the finance cannot comfortably support, and opportunities get missed because the preparation was not done. The biggest breakdowns in property purchases happen in that gap.

Why does preparation decide who wins off-market?

Off-market opportunities are offered through relationships before public listing, and they go to buyers who can move immediately: structure in place, strategy settled, advisers briefed. Preparation, not contacts, is the real barrier. Buyers who are frustrated at constantly missing out are usually losing on readiness, not on price.

The due diligence most investors skip

The second half of the episode is a practical due diligence tour: why the specific street matters as much as the suburb, the checks that surface problems only after settlement when skipped and why cut-price conveyancing is one of the most reliably expensive savings in property. Free and cheap advice has a habit of presenting its invoice later.

Trust lending and realistic contract timelines

For buyers purchasing in trusts, the conversation gets specific: trust lending carries more documentation, more assessment steps and a smaller lender pool, so finance clauses need to reflect reality rather than a standard template. Setting honest timelines up front protects the structure and the contract. Rushing either is where thousands quietly disappear.

Episode breakdown

Key questions this episode answers

What is the biggest mistake property investors make when buying?

Buying the property before building the strategy around it. The finance structure, due diligence, contract timelines and team need to exist before the offer, because they determine whether the purchase supports the portfolio or works against it.

How do off-market opportunities actually work?

They are offered through agent relationships before public listing, and they go to prepared buyers: finance settled, structure in place, advisers briefed. Access is a preparation problem more than a contacts problem.

What due diligence do investors commonly miss?

Street-level assessment, realistic finance clause timelines for trust purchases and quality conveyancing. The checks that get skipped are usually the ones that surface after settlement.

Why do trust purchases need longer finance clauses?

Trust lending involves more documentation, more assessment steps and fewer lenders, so approvals take longer. Honest contract timelines protect both the structure and the purchase. The ownership decision itself is covered in Trust vs Personal Name.

Who is the guest on episode 92?

Jessica Giandomenico, buyer's agent and founder of Vesta Buyers Agency, one year into building the agency.

The takeaway

Buying property is not the hard part. Buying the right property, in the right structure, on the right timeline, with the right people checking the things you cannot see: that is the part that decides whether an investor builds wealth or funds someone else's lesson. Strategy first. Then the property.
