TOOL 04 · OFF-THE-PLAN DUE DILIGENCE

Before you sign, build the bear case.

Off-the-plan is the one purchase where you commit now and settle years later, against a valuation that doesn't exist yet. This builds the case against the deal first — valuation shortfall, settlement risk, body corporate, developer track record and rental-guarantee traps — so you sign with your eyes open.

Off-the-plan due diligence

Valuation shortfall · settlement risk · body corp · developer risk

Copy & Paste
You are a due-diligence assistant helping an Australian investor build the BEAR CASE on an off-the-plan property before signing a contract. Educational only — not financial, credit, legal or tax advice.

WHAT I HAVE (paste or describe):
- Price / price list: [$]
- Property: [config, size, level/aspect]
- Suburb & state: [ ]
- Rental estimate quoted: [$ / week]
- Body corporate estimate quoted: [$ / year]
- Deposit terms: [%]
- Settlement timeframe: [estimated date / months]
- Developer / builder name: [ ]
- Any comparable sales I know of: [ ]

Return exactly these sections:

## 1. VALUATION SHORTFALL RISK
Why the bank's valuation at settlement may come in below the contract price, and what that means for the deposit gap.

## 2. SETTLEMENT RISK
What can change between now and settlement (rates, lending policy, my circumstances, completion delays) and the consequences.

## 3. BODY CORPORATE RISK
Whether the quoted strata estimate looks realistic; what tends to rise after the first AGM.

## 4. RENTAL & RENTAL-GUARANTEE CONCERNS
Whether the rental estimate is plausible; how rental guarantees can be priced into the purchase price.

## 5. SUPPLY RISK
Competing stock settling in the same area at the same time.

## 6. DEVELOPER / BUILDER QUESTIONS
What to ask and verify about the developer and builder track record.

## 7. LENDING QUESTIONS
For a broker, given off-the-plan valuation and finance-approval timing.

## 8. SOLICITOR QUESTIONS
Contract clauses to have a conveyancer/solicitor review (sunset clauses, variations, defects).

## 9. WHAT MUST BE VERIFIED BEFORE PROCEEDING
The non-negotiable checks.

IMPORTANT: Educational due-diligence prompt only. Not financial, credit, legal or tax advice and not a valuation. An off-the-plan contract must be reviewed by a qualified solicitor/conveyancer and the finance by a licensed broker.
Off-the-plan risk is different: you commit now and settle years later, against a valuation that doesn't exist yet. Make AI build the bear case before you sign.

Heads up

A rental guarantee is often priced into the purchase price. A sunset clause can let a developer cancel. These are the clauses an AI prompt can flag but only a conveyancer can rule on — never sign an off-the-plan contract without one.

Numbers organised? The lending structure still needs a human.

AI can prepare the property summary, the assumptions and the risk questions. A credit specialist structures the actual deal — borrowing capacity, lender policy, income treatment, loan structure and the application strategy. Bring your prepared file when it's time.
