A feasibility that survives lender scrutiny.

Costs, end value, margin and funding structure tested the way a credit team will test them — before you take the deal to a lender.

Development feasibility

Does the project actually stack up?

Most feasibilities are built to convince the developer, not to survive a credit assessor. They use round numbers for cost, a hopeful sales figure, and an assumption about GST that nobody has actually confirmed — and they come back from a lender's desk as not yet credible, which on a time-critical site amounts to a decline.

This is for landowners and developers who want to know, honestly, whether a project works before committing further money to it — and for anyone about to take a feasibility to a lender who wants it tested first, not corrected later.

We model the numbers, stress the assumptions a lender will stress, and tell you plainly where the deal is thin.

What you get

The numbers a lender will actually test.

Cost plan tested against reality

Build cost, professional fees, statutory costs, contingency and holding costs, priced properly — not a single round number per square metre.

End value and margin

Gross realisation, then selling costs and GST treatment stripped out to a net figure, and a margin on cost that means something once it is tested.

Funding structure

A shape for the capital stack — how much senior debt, how much equity, where mezzanine might sit — so you know what to take to a lender, not just what you hope to borrow.

Sensitivity testing

What happens if costs run 10% over, sales settle slower than planned, or the valuation lands below the feasibility.

How it works

Six steps to a credible number.

Assemble the inputs

Title, planning position, concept costings, sales or rental evidence.

Model gross to net realisation

Strip out GST and selling costs to arrive at net realisation — the number most lenders actually size a facility against.

Cost the build properly

From a quantity surveyor or a priced builder's estimate, not a rate per square metre.

Shape the funding structure

Senior debt sized at the lesser of loan-to-value and loan-to-cost, with equity or mezzanine bridging the rest.

Stress-test it

A cost overrun, slower sales, a valuation below assumption — and see what the project can actually absorb.

Package it for scrutiny

The way a credit team reads it, with every assumption visible on the face of the document. See how to prepare a feasibility for lender scrutiny.

What it costs. An early scan of a single site is a different job from a bank-ready submission on a multi-stage project, so a feasibility review is scoped to the project and how far along it is. We agree the scope and confirm the fee in writing before starting.

Proof, not promises

Where the numbers were actually tested.

Individual past transactions, included to show how the feasibility work was done. They are not offers, benchmarks or a guarantee of any outcome on another project.

Margin scheme

Norlane, VIC

A fire-damaged, easement-encumbered site valued at $2.6M GRV and $2.4M NRV under the margin scheme, funded against a fixed-price contract with a first drawdown structured at 80% all-up.

Numbers before the valuation

Moama, NSW

A site valued as-is at about $1.15M against a proposed gross realisation of about $11M, modelled month by month and put to a funder before the formal valuation had even been instructed.

Tools & reading

Sketch the shape before you commit.

Start with the free development feasibility calculator for the whole project, then use the calculators in Siare's Implement library to test one part of the shape before your quantity surveyor and accountant firm it up: the development finance calculator for a straightforward funding stack, the renovation feasibility solver for a renovate-to-sell project, and the knockdown rebuild calculator where that is the comparison. See the full library.

Questions

What developers ask first.

Will Siare tell me whether the GST margin scheme applies to my project?

No, and be cautious of anyone who offers to. Eligibility is a question for your accountant or registered tax adviser. Our role is carrying the confirmed position accurately into the numbers.

Do you lend against the feasibility?

No. Siare arranges finance as broker. The feasibility is what we take to the lenders whose policy fits — see development and construction finance.

What if the numbers don't stack up?

We will tell you plainly, and say why. Better to know before you are committed to a site than after settlement.

Is this the same template a bank uses?

It is structured the way a credit team reads one, with assumptions stated on the face of it. It remains your feasibility, and the assumptions are yours and your accountant's.

How long does a review take?

It depends on how complete the inputs are. A site with title, concept costs and sales evidence ready moves faster than one starting from a blank page.

Can you review a feasibility I have already built?

Yes. An independent check before it goes to a lender is one of the more common ways this work starts.
