Planning a property development involves much more than purchasing land and arranging construction. Before applying for property development finance, you need to understand the total project cost, expected value, funding requirements, timing and how the finance could ultimately be repaid.
A property development feasibility study brings these details together in one financial and project plan. It can help developers test whether a project is realistic before committing significant capital and prepare the information that may be required during a development finance assessment.
Whether you are considering a residential development, townhouse project, land subdivision finance or another eligible property development in Australia, a realistic feasibility can make the finance process easier to understand and help identify potential risks early.
What Is a Property Development Feasibility Study?
Why Is a Feasibility Study Important for Property Development Finance?
Getting development finance approved usually involves more scrutiny than a standard home loan, mainly because the lender isn’t just assessing you, they’re assessing the project as well.
Depending on who you’re borrowing from and what you’re building, that assessment might look at things like:
- Total development cost
- Project feasibility
- Property value
- Expected completed value
- Borrower equity
- Development experience
- Planning and approvals
- Construction arrangements
- Proposed exit strategy
A feasibility study is really what ties all of that together.
Take a simple example. A project can look profitable if you only account for the land and the build. But once you factor in finance costs, professional fees, approval costs, selling costs and a contingency buffer, the numbers can tell a very different story.
That’s exactly why a feasibility needs to be grounded in realistic assumptions, not a rosy best case that falls apart under any real pressure.
What Should a Property Development Feasibility Study Include?
Land Acquisition Costs
Start with what it actually costs to buy the site. If you already own the land, work from its current value, any existing finance against it, and how much equity you’ve genuinely got sitting in it.
Depending on the project, the land budget may include:
- Purchase price
- Stamp duty
- Legal and conveyancing costs
- Acquisition-related fees
- Due-diligence expenses
- Existing debt
It’s worth digging into the site’s planning position early too, since zoning, approvals and other site constraints can end up shaping what you’re actually allowed to build.
Construction Costs
Construction is usually the single biggest line item in a development budget, so it deserves more than a rough guess.
Include the expected cost of:
- Building works
- Site preparation
- Demolition, where required
- Civil works
- External works
- Utility connections
- Landscaping
- Construction variations
Wherever you can, work from detailed costings or actual construction documentation rather than a broad, back-of-envelope figure.
A construction budget grounded in reality also makes it far easier to work out how much funding you’ll actually need, and how exposed the project is if costs creep up along the way.
Professional and Planning Costs
Most developments end up involving a fair few professionals and approval processes, more than people often expect going in.
Depending on the project, you may need to allow for:
- Architect or designer fees
- Town planning
- Engineering
- Surveying
- Quantity surveying
- Project management
- Legal costs
- Accounting
- Development approval costs
- Building approval and certification
It pays to build these into the feasibility from day one rather than adding them in later as an afterthought.
Finance Costs
Finance is a cost of the development itself, not a figure you tack on at the very end once everything else is settled.
Your feasibility may need to account for:
- Interest
- Establishment fees
- Valuation fees
- Legal fees
- Other lender charges
- Progressive funding costs
- Additional holding costs if the project is delayed
Exactly how this looks will come down to the lender and the specifics of the project.
Contingency
Even the most carefully planned developments run into surprises somewhere along the way.
A contingency allowance can help absorb things like:
- Construction variations
- Material cost changes
- Site issues
- Delays
- Additional professional requirements
- Approval-related changes
A contingency won’t make the risk disappear, but it does make the overall feasibility a lot more realistic.
How Do Lenders Assess a Development Feasibility?
Every lender has its own checklist, but a handful of areas tend to come up in almost every development finance assessment.
Project Feasibility
The lender wants to see, based on what you’ve provided, whether the development genuinely looks workable, financially and practically.
Total Development Cost
Your feasibility should make it clear how the overall budget was arrived at, including the major expenses that go into it.
Equity Contribution
How much equity or capital you’re putting in yourself often plays into the finance assessment. What’s required tends to shift depending on the project, the lender, and how the finance is structured.
Development Experience
Your track record can matter here, especially on bigger or more complicated projects. That said, criteria differ from lender to lender, and experience is just one piece of the puzzle.
Planning and Approvals
Lenders generally want to understand where the project sits with approvals, and whether the relevant planning and construction requirements have actually been dealt with.
Builder and Construction Details
For construction projects, details like who the builder is, the construction contract, the costings and the timeframe can all feed into the assessment.
Expected End Value
Whatever completed value goes into the feasibility needs to be realistic, and ideally backed by solid evidence rather than optimism.
Exit Strategy
A lender will almost always want to know exactly how the finance is meant to be repaid.
Depending on the project, this could involve:
- Sale of completed properties
- Refinancing
- Retaining the completed property and refinancing
- A combination of sale and refinance
How to Prepare a Property Development Feasibility Study
Here’s roughly how the process tends to unfold.
Step 1: Define the Project
This part’s just about nailing down the facts. Site location, size, what’s actually being built, how many dwellings or units, and what it’s ultimately going to be used for once construction wraps up.
Step 2: Calculate Total Costs
Add up what the project is going to cost, all of it. Land, construction, professional fees, approvals, finance, selling costs. Throw in some contingency too, because something always comes up that you didn’t plan for.
Step 3: Estimate the Completed Value or Revenue
Try to land on a realistic figure for what the finished project is worth or could bring in. Base it on actual market evidence, not a hopeful guess, and jot down why you landed on that figure.
Step 4: Determine Your Equity Position
Work out how much of your own money is going into this, and what gap that leaves for development funding.
Step 5: Test Different Scenarios
One version of the numbers isn’t enough. Run it through a few situations, costs blowing out, sale prices coming in lower, the build dragging on longer than planned, and see if the project still holds up.
Step 6: Check Planning Requirements
Have a proper look at what the site actually allows before getting too committed to your figures. That covers zoning, approvals, and whatever planning rules apply to that particular block.
Step 7: Prepare Supporting Documents
Time to gather the paperwork. Plans, contracts, costings, financials, approvals, plus anything else a lender might come back and ask for.
Step 8: Explore Development Finance
Once the feasibility is in decent shape, it’s time to look at Property Development Finance options in Australia that suit the project and what different lenders want.
How Do You Estimate the Expected End Value?
The expected completed value is one of the most important figures in the whole feasibility study.
It should be grounded in realistic evidence, not simply the highest price you could imagine achieving on a good day.
Relevant factors can include:
- Location
- Property type
- Size
- Specifications
- Comparable completed properties
- Current market conditions
- Expected demand
- Independent valuation evidence
For something like a townhouse or multi-dwelling project, expected values should be backed by genuinely comparable evidence, rather than assuming every dwelling will sell for the same price.
Keep in mind a lender may order its own valuation too, and that figure can end up differing from whatever’s in your feasibility.
What Is Development Profit or Margin?
A basic feasibility usually works out estimated development profit roughly like this:
Expected Revenue − Total Development Costs = Estimated Development Profit
Total development costs can pull in land, construction, professional costs, planning, finance, selling expenses and contingency.
Different developers and lenders can calculate margin slightly differently, so it’s important the assumptions and method are spelled out clearly rather than left implied.
What actually matters is looking at the project’s likely outcome once every relevant cost is accounted for, rather than fixating on just the purchase price and the build cost.
What Documents May Be Needed for a Development Loan Application?
Requirements vary from lender to lender, but a development finance application will often call for:
- Identification documents
- Contract of sale
- Property details
- Development plans
- Planning documents
- Building plans
- Construction contract
- Builder information
- Detailed project costings
- Feasibility study
- Valuation information
- Financial statements
- Asset and liability information
- Existing loan details
- Project timeline
- Exit strategy
Having all of this organised in advance makes it a lot easier to explain the project properly, and to respond quickly when a lender comes back with questions.

Property Development Feasibility vs Property Valuation
These two things get mixed up fairly often, but they’re not the same exercise.
A feasibility study looks at the overall economics of the development, the costs, the revenue, the finance, the timing, and how it’s all likely to play out.
A property valuation, on the other hand, is an independent opinion on what a property is worth, prepared for a specific purpose.
Your feasibility might include an estimated completed value, but that number shouldn’t be treated as a stand-in for the formal valuation a lender will actually rely on.
Understanding that difference helps you avoid building an entire finance application around figures that haven’t been independently tested.
Common Property Development Feasibility Mistakes
Underestimating Total Costs
Leave out professional fees, approvals, finance or selling costs and the project budget can look very different once reality catches up.
Overestimating Property Values
Lean on unrealistic completed values and the development can appear far more profitable on paper than it actually is.
Ignoring Finance Costs
Interest and lender charges need to be in the feasibility from the start, not bolted on later.
Not Allowing for Delays
A longer construction or approval period tends to push up holding and finance costs, sometimes more than people expect.
Using Unrealistic Sales Assumptions
Expected revenue needs to be backed by sensible market evidence, not hope.
Having an Unclear Exit Strategy
The feasibility should spell out clearly how the development finance is actually going to be repaid.
Focusing Only on Interest Rates
When you’re comparing finance options, look at the whole structure, fees, funding conditions, drawdowns and repayment terms, not just the headline rate.
Can First-Time Developers Access Property Development Finance?
Potentially, yes, though it comes down to the project, the borrower, and the individual lender’s criteria.
A first-time developer might be assessed on things like:
- Project feasibility
- Financial position
- Equity contribution
- Development experience
- Builder and professional team
- Planning status
- Project complexity
- Exit strategy
A strong feasibility won’t guarantee approval on its own, but it gives everyone a much clearer picture of the project, and it helps you get the right information together for the assessment.
Final Takeaway
A good property development feasibility study should tell the complete financial story of the project, not just the flattering parts.
That means working through:
Land → Planning → Construction → Professional Costs → Finance → Contingency → Value/Revenue → Exit Strategy
Getting these details sorted before you apply for development finance helps you spot cost gaps early, pressure-test your assumptions, and get a realistic sense of how much funding you’ll actually need.
For property development projects across Australia, the right finance structure will always depend on the site, the project type, your position as a borrower, and the individual lender’s criteria.

FAQ
It's an assessment of a proposed development's costs, funding requirements, expected value or revenue, risks, timing, and likely financial outcome.
Lenders tend to look at the total development cost, expected value, borrower equity, project feasibility, planning status, development experience, construction arrangements and exit strategy, though exactly what matters varies between lenders and projects.
It usually starts with defining the project, then working through the major costs, figuring out the completed value or revenue, working out equity and funding needs, testing a few different scenarios, and setting out the exit strategy.
Depending on the project, that can mean land, construction, professional fees, planning and approval costs, infrastructure, finance, selling costs and contingency.
A feasibility study helps first-time developers lay out the project's costs, funding needs and expected outcome in a structured, credible way, even though specific lender requirements will still vary.
No. A feasibility looks at the economics of the whole development, while a valuation is an independent opinion on property value prepared for a specific purpose.
