Understanding BUC Progressive Payment

Frequently Asked Questions

A BUC progressive payment is the staged payment structure for a Building Under Construction property. Instead of disbursing the full loan upfront, payments are made progressively as the project reaches specific construction milestones.

For BUC properties, payments are usually made in stages such as the booking fee, signing of the Sale & Purchase Agreement, foundation works, reinforced concrete framework, brick walls, roofing or ceiling, fittings and services, vacant possession, and legal completion.

The exact schedule should always be checked against the Sale & Purchase Agreement and developer notices.

Estimating your progressive payment schedule early helps you understand when cash, CPF, and bank loan disbursements may be needed. This is especially important because your cash flow commitment may increase as more of the loan is progressively disbursed.

CPF Ordinary Account savings may be used for eligible property payments, including downpayment, housing loan, stamp duty and legal fees, subject to CPF rules and applicable usage limits.

CPF Board also highlights that CPF savings are meant for retirement, so buyers should balance CPF usage with cash planning.

Yes, CPF OA savings can generally be used for progressive payments if you have sufficient CPF available, subject to CPF usage limits and approval. However, CPF cannot be used to cover the required cash portion of the purchase, so buyers should still ensure they have enough cash buffer for any shortfall, stamp duty, legal fees, or payments not fully covered by CPF and the bank loan.

Yes, it is highly recommended to speak with a professional mortgage advisor before buying a BUC property. A BUC purchase involves progressive payments, CPF usage, bank loan disbursements, interest costs, and cash flow planning across different construction stages.

A mortgage broker can help you understand how much you need to prepare, compare suitable bank loan packages, and estimate your repayment commitments before you commit to the purchase.

This helps you plan with greater confidence, avoid unexpected cash shortfalls, and choose a loan structure that fits your financial situation.
