📅 Repayment Frequency
📊 Cashflow by Construction Stage

During construction you pay interest-only on the amount drawn — not the full loan. Repayments grow progressively with each progress payment.

🏠 After Build Completes — Full P&I Repayments

Once construction is done and you move in, your loan converts to principal & interest on the full amount. Rent savings offset total outgoings.

💡

Key Insight: Repayments are lowest at the start and grow with each progress draw. Most lenders require your own funds to be used first before drawing on the construction loan. A broker can structure your loan to minimise cashflow pressure during the build.
