A development feasibility model and a bank valuation are not two attempts at the same number. One is a forward-looking model of a project that does not exist yet. The other is a professional opinion about value, prepared to a defined instruction and dated to a specific day. When they disagree, the gap is usually structural rather than arithmetic. Neither number is wrong. They were built to answer different questions.
This page sets the two side by side, separates the three values developers routinely conflate, and treats a low valuation as information rather than a verdict.
Key Takeaways
- Different purpose, client, date, basis and signatory. The divergence is designed in from the moment each document is commissioned.
- Three figures get mixed up: as-is security value, as-if-complete market value (often called GRV), and the developer's residual land value.
- Valuer conservatism is systematic, not personal. It follows from settled comparable evidence, a stated basis of value, and a date fixed by the instruction.
- The valuer does not set the loan. ANZVGP 112 states it is generally not appropriate for a valuer to recommend a maximum or minimum loan percentage. That is the lender's commercial decision.
- A feasibility or intelligence report is not a valuation. A formal valuation comes from a qualified valuer, normally instructed by the lender.
Feasibility Model vs Lender's Valuation: Side by Side
| Dimension | Developer's feasibility model | Lender's development valuation |
|---|---|---|
| Purpose | Decide whether to proceed, and at what land price | Advise on value for a defined purpose, commonly security for lending |
| Who commissions it | The developer, for their own decision; sometimes an investor or partner | The lender, for its credit decision |
| Date / base date | Forward-looking: a programme of dates across the project's life | A single stated valuation date to which the opinion applies |
| Basis | An assumed development scheme, its cost, its revenue and a target return | A stated basis of value, commonly as-is and as-if-complete |
| Assumption source | The developer's own commercial intentions and target return | The instruction, the professional standards, and the lender's own definitions |
| Evidence | Their own cost plan, quantity surveyor or builder pricing, agent input, sales assumptions | The valuer's verified comparable market evidence, adjusted for the subject |
| Who may issue it | Whoever built the model; no valuation standard attaches to it | A qualified valuer holding the qualifications prescribed for that business |
Three rows do most of the work: date, basis and evidence. ANZVGP 112 is the Australian Property Institute's guidance on valuations for mortgage and loan security, effective 1 January 2025. It states that an "as if complete" valuation assumes the proposed work is already completed at the date of valuation and reflects market conditions at that date. An existing "as is" value must be provided alongside it. The International Valuation Standards define the valuation date as the point in time to which the valuation applies, and require the basis of value to be agreed before the valuer begins.
A feasibility has none of those attributes, because it is not an opinion of value at all. To see how the developer-side number is derived, our guide to running a property development feasibility builds one line by line.
Why the Numbers Differ
Four mechanisms account for most of the gap.
They answer different questions. A feasibility asks whether a project works and what the developer can pay for the site. A valuation asks what an asset is worth, for a stated purpose, on a stated date.
They sit on different dates. A valuation standard insists the figure is date-specific, because markets move. The same asset valued on another day may produce a different and equally correct result.
They draw on different evidence. The valuer works from verified settled transactions, adjusted for differences between each comparable and the subject. Settled sales are historic by construction, so a rising market tends to produce figures that trail current asking prices. The developer's model rests instead on the scheme they intend to build.
The definitions belong to the lender. APRA does not define "qualifying development costs" or "qualifying presales" itself; it expects each lender to define them in policy. Rebuild a project onto a different definition and the answer moves without anyone making an arithmetic mistake. A lower facility can also reflect presale, equity or policy constraints rather than valuation alone.
Three Values That Get Confused
This is where most small-developer funding gaps originate: three different numbers treated as one.
| Value | Whose number | What it answers | What it serves |
|---|---|---|---|
| As-is security value | The lender's valuer | What is the asset worth today, in its current state? | Whether the security supports the debt |
| As-if-complete market value (often called GRV) | The lender's valuer | What is the finished project worth, assuming the works are complete, on today's market? | End value and repayment |
| Developer RLV | The developer's model | What is the most I can pay for this site and still hit my target return? | The acquisition decision and the offer |
The RLV comes from a separate discipline. Our illustrative residual land value example uses three South Australian townhouses, all figures GST-exclusive and invented for demonstration rather than drawn from a real project. It produces a gross realisation of $3,000,000, non-land development costs of $2,000,000, a target profit of $400,000 and therefore an RLV of $600,000. Note what it never computes: a current market value for the site as it stands. It was not built to. It assumes the scheme and prices the land as the residue.
The confusion runs both ways. A developer treats the as-if-complete figure as a promise and reads the as-is figure as a judgement on their scheme. Neither reading survives contact with what each instrument was built to do. On smaller infill sites the scheme itself is often the variable, as our piece on feasibility on a small infill site sets out.
Why the Lender's Assumptions Tend to Be More Conservative
- The evidence is backward-looking. Comparable settled sales are the strongest evidence of value, and they describe transactions that have already happened.
- The date is fixed. A valuation reflects conditions at the valuation date and does not predict the value at actual completion. A project settling in two years is valued on today's market, not tomorrow's.
- Off-the-plan pricing is treated cautiously at the regulator's direction. APRA's APG 223 observes that developer prices might not represent a sustainable resale value, and that a prudent lender would make appropriate reductions to off-the-plan prices, or seek independent valuations.
- Cost assumptions get rebuilt. ANZVGP 112 directs that a significant gap between the builder's tender and the valuer's check cost be reported to the lender. The guidance recommends a quantity surveyor provide further advice.
And the boundary: ANZVGP 112 is explicit that it is generally not appropriate for a valuer to recommend a maximum or minimum loan percentage or amount. Lending is the lender's commercial decision, which is why a facility can move without the valuation changing at all.
When the Valuation Comes in Low: What Can Follow
Options with costs attached, not outcomes.
- Meet the gap with equity. The most direct route, and it consumes capital that might otherwise fund the next project.
- Revisit the land price. Only viable if the contract or negotiation still allows it. A signed contract does not become renegotiable because a valuation landed lower.
- Change the scheme. Different product mix, staging or scope can shift what a valuer can support, but redesign, reapproval and lost time belong in the comparison. Approval timing feeds directly into this, which is where SA development approval timeframes matter.
- Strengthen the evidence. Replace assumptions with endorsed plans, verified areas, executed contracts and genuinely comparable settled transactions. Presales are the strongest answer to a weak end-value assumption, because they substitute real contracts for estimates.
- Reconsider the project. If the supported value no longer covers the capital stack, more debt can deepen the problem rather than solve it.
A low valuation is also information about how the market reads the project, which is useful well beyond the funding question.
What a Feasibility or Intelligence Report Is Not
DDDI's feasibility analyses and intelligence reports, and the reports prepared by Cyberate PM, are not formal valuations. They are decision-support models and research, prepared to support a commercial decision rather than opinions of value prepared to valuation standards. They are not a substitute for one and cannot be relied on as one.
A formal valuation must come from a valuer holding the qualifications prescribed for carrying on that business. In South Australia, the Land Valuers Act 1994 provides that a person must not carry on business, or hold themselves out, as a land valuer without the qualifications required by regulation. The Land Valuers Regulations 2024 list those qualifications. They include current Australian Property Institute certification as a Certified Practising Valuer or Residential Property Valuer.
Valuers in South Australia generally do not need a licence to value property; the regulated point is the qualification requirement. For lending, the valuation is normally instructed by the lender, and a report you commissioned yourself generally cannot be relied on until the valuer consents in writing and reissues it.
DDDI's research and intelligence services cover decision support and market research, not valuation. Nothing on this page is valuation, credit, tax or legal advice.
FAQ
Can I use my own feasibility as a valuation?
No. A feasibility is a forward-looking model of a project that does not exist. A valuation is a professional opinion of value, prepared to a stated basis on a stated date by a qualified valuer.
Why did the bank's valuation come in below my numbers?
Usually because it answers a different question: a different date, different evidence, a basis of value set by the instruction, and cost definitions owned by the lender rather than the developer.
Does a low valuation mean my project doesn't work?
Not necessarily. It means the supported end value, or the security value, is lower than you assumed. The productive response is to run the valuation's figures through your model as a scenario and see what survives, rather than arguing the valuer into a different opinion.
Can I get the valuation changed?
Sometimes. Where there is a factual error or evidence the valuer did not have, such as endorsed plans, verified areas, executed contracts or better comparables, a review process may exist. A review can also confirm the original figure.
Where This Leaves You
The two documents are complements, not rivals. The feasibility tells you whether to proceed and what you can responsibly pay for the site. The valuation tells a lender what it can rely on. Build your model knowing that a second reader will rebuild it on their own definitions. That habit prevents more funding surprises than any spreadsheet feature.
