Frequently Asked Questions
How accurate is this feasibility calculator?
This tool provides indicative estimates based on current Western Sydney market data and typical construction costs. For precise figures, we recommend a professional feasibility study with quantity surveyor costings. Buildana offers free initial consultations.
What is a development margin and what's a good target?
Development margin is net profit divided by end value. A healthy development margin is typically 15–20%+ for the risk involved. Below 10% is generally considered too tight given the risks of construction and property development.
What's the difference between DA and CDC?
A Development Application (DA) goes through full council assessment (45–120 days). A Complying Development Certificate (CDC) is a fast-track approval via a private certifier (8–30 business days), available when your project meets specific standards in the relevant codes.
What costs are NOT included in this calculator?
This calculator doesn't include furniture/staging, marketing campaigns, GST implications for developers (margin scheme vs standard), legal disputes, environmental remediation beyond basic estimates, or costs relating to subdivision registration.
Can I use this for a property I don't own yet?
