AI summary

Financing a new build starts with a construction loan. You should aim for a deposit of at least 10% of the total land and build cost. The loan is paid out in stages via progress payments as construction milestones are met, often with interest-only repayments during this period.

Key contract types include simple turn key packages or more flexible build-only contracts. To ensure a smooth process, talk to lenders or a mortgage broker early and budget for potential cost overruns.
