AI summary

Financing a new build requires a construction loan, which differs from standard mortgages. You'll generally need a deposit of at least 10% of the total land and build cost. Funds are drawn down in stages as progress payments to your builder.

To apply, you'll need a build contract, consents, and a registered valuation. Key contract types are Turn key (all-inclusive) and Build-only (more flexible). Be cautious of provisional costs (PCs) and secure pre-approval for more than the estimated budget.
