A property can be a good buy for different reasons. It may be a strong price for the location, a home worth holding for years, a place to renovate, a knockdown rebuild or a development site. The reason must suit your money, time and plans.

The first check does not replace legal, building, finance or planning advice. Its job is to show whether the property deserves more of your time and money—or whether you should walk away now.

1. Check that the property is still for sale

Start with the current listing, how it is being sold, the deadline and any change in status. An old auction date or withdrawn listing makes the rest of the work useless. Note when the facts were checked and check again before acting.

2. Say why the property stood out in one sentence

Use a clear reason: the price looks strong beside similar sales, the location is rare, the rent may help with the loan, an approval already exists, the land is unusually large or the home has room to improve. Do not call it “below market” unless you know the current price and similar sales prove it.

If the opportunity cannot be explained plainly, it is probably not ready for deeper work.

3. Use each nearby sale for a clear reason

Do not average three nearby sales and call it a valuation. Use an older home to show the lower end, a renovated or developed property to test the plan, and a clearly better property to show the upper end.

Compare the land, home size, condition, position, water view, parking, allowed use and sale date. The gaps matter more than the suburb name.

4. Compare the ways you could use the property

For an older waterfront home, that may mean hold and improve, renovate, or knock down and rebuild. For a development site, it may mean build the current approval, seek a different approval, or resell the site.

Each path needs its own first numbers and evidence. The most impressive path is not always the best one. A new luxury home can cost more than similar finished homes have sold for. When the land, build and other costs are too close to the possible finished value, stop and get better sales and cost evidence before treating the rebuild as a real option.

5. Count the full cost—not just purchase and construction

Add transfer duty, legal work, inspections, loan and holding costs, design and approvals, demolition or repairs, insurance, selling costs and extra money for surprises. The Queensland Revenue Office has the official transfer-duty calculator. You still need to enter the buyer's real details and any discount they may receive.

Start with what similar finished properties have sold for. Take away the work, other costs and money for surprises. The amount left is the rough maximum price in that example. It is not an offer or advice.

6. Check what it may cost to own while you wait

If the plan needs time, use recent rent evidence and compare it with interest and normal ownership costs. Show the weekly and monthly amount left over or still to pay. Do not hide principal repayments, vacancy, management, maintenance, insurance or body corporate costs when they apply.

A property can have a strong long-term story and still put too much pressure on the buyer each month.

7. Check the problems that could make you walk away

Write down the checks that could change the decision: planning use, approval conditions, services, flood, insurance, building condition, tenancy legality, waterfront structures, access, finance and the contract. Queensland's seller disclosure scheme does not replace the buyer's own searches, inspections and legal advice. Have a solicitor or conveyancer check the contract and relevant disclosure material.

What a useful first report should tell you

why the property made the shortlist;
the current timing and status;
which sales support the opportunity and what each one proves;
the useful ways to own or improve it;
the rough finished value, work, other costs and money for surprises;
what the rent may cover each week;
the open checks and deal-killers; and
what would make you keep going, check more or walk away.

It should give a useful rough range when the first sales and costs can be checked. It must also make clear what has been checked, what came from the listing and what is still only a rough number.

Use the shortlist to save time—not skip due diligence

Deal Alerts save time by doing the first check. They can show why the property stood out, bring the first facts together and point to the path worth checking. They do not replace building, planning, legal, finance, tax, insurance or valuation advice.
