As-If-Complete Valuations: How Construction Loans Are Sized

In short: Lenders size construction loans on the as-if-complete valuation: the valuer's estimate of what the finished property would be worth today, built to the plans and contract. The loan is usually the lesser of a percentage of that value and a percentage of the total cost of land plus build. When the valuation comes in below land value plus contract price, which is common, the difference comes out of your contribution, not the lender's.

Key takeaways

The valuer reports the land value today and the as-if-complete value at today's market, not a forecast.
Many lenders apply two caps - LVR on the end value and loan-to-cost on land plus build - and lend the lesser.
At an 80% LVR, every $1 of valuation shortfall adds about 80 cents to the contribution you must make.
Site works, premium finishes and over-capitalising for the street add cost without adding equal value.
Progress inspections re-test the value of work in place and the cost to complete before every draw.
A short valuation can be reviewed with better evidence, but fixing the budget is usually the real answer.

What is an as-if-complete valuation?

Before a lender commits to a construction loan, it orders a valuation from a valuer on its panel. The valuer inspects the land, reviews the plans, specifications and building contract, and reports two main figures: the current value of the land, and the as-if-complete value - what the finished property would sell for today if it were already built to those plans. It is a value at today's date, not a forecast of the market on completion day.

The report usually also notes the contract price, comments on whether it looks reasonable for the work, and sets out the stages the valuer will inspect. The lender instructs the valuer and relies on the report. You usually pay the fee, but the valuation is the lender's, prepared for its lending decision.

An automated valuation model cannot do this job, because there is no finished house to compare with sales. Construction loans need a full valuation with an inspection.

Figure	What it measures	How the lender uses it
Land value	The site in its current state	Limits the land portion and the first draw
Total cost	Land value or price, plus contract price and allowances	Loan-to-cost test and your contribution
As-if-complete value	The finished property at today's market	LVR test on the full loan limit

How do lenders size a construction loan from the valuation?

Many lenders apply two caps and lend the lesser: a maximum LVR on the as-if-complete value, and a maximum share of the total cost, often called loan-to-cost. Owner-occupied home builds are mostly LVR-driven; for investment, multi-dwelling and commercial builds, the loan-to-cost test usually bites too.

For illustration only - example caps and figures, not any lender's policy or an offer. Land bought and valued at $600,000, a $700,000 fixed-price contract, so a total cost of $1,300,000. The lender caps the loan at 80% of the as-if-complete value and 85% of total cost ($1,105,000).

As-if-complete value	80% of value	85% of cost	Loan (the lesser)	Minimum contribution (cash or land equity)
$1,250,000 (below cost)	$1,000,000	$1,105,000	$1,000,000	$300,000
$1,300,000 (equal to cost)	$1,040,000	$1,105,000	$1,040,000	$260,000
$1,400,000 (above cost)	$1,120,000	$1,105,000	$1,105,000	$195,000

Two lessons sit in that table. A $50,000 valuation shortfall (from $1,300,000 to $1,250,000) lifts the contribution you must make by $40,000, 80 cents per dollar. And a valuation above cost does not translate fully into extra borrowing, because the loan-to-cost cap takes over.

The lender then tests whether you can service the full limit, not the first draw. Banks assess repayments at least 3 percentage points above the loan rate, the buffer APRA kept on 28 May 2026, and for a home you will live in they must verify your financial situation under the responsible lending obligations ASIC describes.

Why do valuations come in under the contract price?

Because a valuer measures what buyers would pay, and a building contract measures what it costs to build. They diverge for predictable reasons:

Cost item	Adds to cost	Adds to market value?
Site works on a sloping or rocky block: retaining, piers, excavation	Often significantly	Little: buyers rarely pay for what they cannot see
Premium finishes and custom joinery	Yes	Partly, depending on the street and buyer pool
Pools, outdoor kitchens, home theatres	Yes	Often less than their cost
Floor area beyond what the street supports	Yes	Capped by local comparable sales
Builder's margin and contract allowances	Yes	Not directly
Land bought above market	Already paid	Valued at today's market only

Rising build costs widen the gap. In the ABS Producer Price Indexes for the June quarter 2026, house construction output prices rose 5.9% over twelve months. Valuers anchor the as-if-complete figure to sales of comparable homes, so if established prices in your area have not kept pace with building costs, a new house can cost more to build than the market pays for its equivalent. Builders' order books are also full: the ABS counted 248,733 dwellings under construction in the June quarter 2026 in its Building Activity release, and busy builders price accordingly.

Over-capitalising for the location is the most common cause. A $900,000 build on a $600,000 block in a street where finished homes sell around $1,100,000 is unlikely to value at $1,500,000, however good the house is.

How does the valuer treat the land?

The land is valued at today's market in its current state. A recent purchase price is strong evidence, and some lenders use the lower of price and valuation for land bought recently (indicative; the look-back period varies). If you have held the land for years and it has risen, that rise is equity you can count towards your contribution.

For example, land bought for $450,000, now valued at $600,000, with $200,000 owing, gives you $400,000 of equity in the land. Against the $1,300,000 total cost above, that equity alone exceeds the $260,000 to $300,000 contribution, so no extra cash would be needed in either of the first two cases.

Lenders are more conservative on land alone than on a finished house, because vacant land is harder to sell and produces no income. That limits how much of the land portion can be borrowed before construction starts. Our worked guide to LVR and equity calculations shows the arithmetic for land and finished values side by side.

What happens at the progress inspections?

The as-if-complete valuation is not the valuer's last word. Before each draw, the lender sends a valuer back to confirm the stage claimed is finished, that the work matches the plans, and that the undrawn funds still cover the cost to complete. Unauthorised changes, defects or a stage claimed early can all reduce or delay a draw.

On larger or more complex jobs - multi-dwelling projects, commercial buildings, cost-plus contracts and large loans - lenders appoint a quantity surveyor instead of, or alongside, the valuer.

Point	Valuer's progress inspection	Quantity surveyor (QS)
Typical jobs	Single houses on fixed-price contracts	Multi-dwelling, commercial, cost-plus, large loans
Before the loan	As-if-complete valuation	Initial report on budget, contract, program and builder
During the build	Stage inspections	Monthly reports certifying work done and cost to complete
Fees	Per inspection, usually charged to you	Higher, per report, usually charged to you

Inspection fees and the timing of each draw affect your holding costs. The construction progress draw calculator shows the interest stage by stage.

What can you do when the valuation falls short?

Check the report for errors: wrong plans, missing inclusions, wrong land area, or comparable sales that are older or smaller homes.
Give the lender better evidence to pass on: final plans, the full specification, the signed contract with inclusions, and recent sales of comparable new homes.
Ask whether the lender will request a review. The lender controls this, and a review may not change the figure.
Value-engineer the build: remove items that add cost but little value, such as an oversized floor plan or premium extras.
Contribute more, in cash or as equity in another property.
Ask another lender. Lenders use different valuers and caps, although valuers working from the same sales often land close together.

Two things not to do: inflate the contract price to lift the loan, or agree a side deal with the builder to rebate part of it. Both misrepresent the security to the lender and can amount to fraud.

How do banks, non-banks and private lenders use the valuation?

Lender type	How the valuation is used (indicative)	Typical extra conditions
Banks	LVR on the as-if-complete value; higher LVRs possible for owner-occupiers with mortgage insurance	Fixed-price contract, standard draw schedule, full serviceability
Non-bank lenders	LVR on the end value plus loan-to-cost tests on investment builds	More flexibility on contract type and borrower profile, at a higher cost
Private lenders	Lower LVRs on the end value, often with loan-to-cost limits and the exit in view	Short terms, capitalised interest, a refinance or sale at completion

The same valuation can therefore produce quite different loans. Our guide to why borrowing power varies between lenders explains the servicing side of that difference.

What should you do next?

Before you sign the building contract, estimate the as-if-complete value yourself from recent sales of comparable new homes in the street and suburb, then compare it with land value plus contract price. If cost exceeds likely value, change the design or budget now, while it is cheap to do so. Then work out your contribution under both an LVR cap and a loan-to-cost cap.

Frequently asked questions

What does as-if-complete value mean?

It is the valuer's opinion of what the finished property would sell for today, assuming it is built to the plans, specifications and contract the lender has. It is a value at the date of the valuation, not a forecast of the market on completion, and it is the figure most lenders use to set the LVR on a construction loan.

Why is my construction valuation lower than the land and build cost?

Usually because some costs add little market value - site works, premium extras, a house larger than the street supports - or because building costs have risen more than prices of comparable homes. The valuer measures what buyers would pay, not what it costs to build.

Can I challenge a construction loan valuation?

You can ask the lender to request a review and supply better evidence: final plans, the full specification, the signed contract and comparable sales of new homes. The valuation belongs to the lender, so it decides whether to ask, and a review may not change the figure.

Does the lender lend on the as-if-complete value or on the cost?

Often both. Many lenders cap the loan at a percentage of the as-if-complete value and at a percentage of total cost, then lend the lesser. Owner-occupied home builds tend to be LVR-driven; investment and multi-dwelling builds usually face a loan-to-cost test as well.

Who pays for construction loan progress inspections?

Usually the borrower. The lender instructs the valuer or quantity surveyor and charges the fee to you, typically per inspection or report. A build with more draws, or a cost-plus contract with monthly invoices, means more inspections and higher total fees.
