AI summary

A construction loan is essential for financing a new build. You'll generally need a deposit of at least 10% of the total land and construction cost.

Unlike a standard mortgage, funds are drawn down in stages via progress payments to your builder as work is completed. Key contract types include simple Turn key packages or more flexible Build-only agreements. Be mindful of provisional costs (PCs), which can cause budget blowouts. It’s best to consult lenders or a mortgage broker early.
