Construction loan drawdown: how progress payments work建筑贷款放款: 进度款如何运作
A construction loan differs from a standard home loan in one key way: funds are released in stages rather than as a lump sum. Each release is called a drawdown, and it matches a defined stage of the building process.
Most lenders follow a standard progress payment schedule. For a typical residential build, you can expect drawdowns at slab or foundation completion, framing stage, roof cladding and waterproofing, internal lining and joinery, and final completion or code of compliance. Each drawdown usually covers 10-25% of the total loan amount, depending on the contract.
Before each drawdown, the lender requires a progress inspection. An independent valuer or the lender's own inspector visits the site and confirms the stage is substantially complete. Only then are funds released, usually paid directly to the builder or drawn into the borrower's loan account.
Borrowers should understand that interest is charged only on the drawn balance, not the full loan amount. In the early stages the interest cost is low, rising as more funds are drawn. This structure can help with cash flow during construction, provided the borrower has a realistic budget for the initial deposit and any cost increases.
Delays can happen. Weather, material shortages, or trades becoming unavailable may push a stage past its expected date. Lenders may grant extensions, but interest continues accruing. A common practice is to build in a contingency buffer: most lenders expect at least 10-15% of the contract sum as a contingency, though the exact requirement varies by lender and project complexity.
Drawdowns typically take 5-10 business days from inspection to payment. It is wise to submit drawdown requests well before the next trade is due on site, so that work can continue without interruption.
建筑贷款与普通住房贷款的一个关键区别在于：资金是按阶段释放，而非一次性放款。每次放款称为一次提款，对应建筑过程中的某个特定阶段。
大多数贷款机构采用标准进度付款计划。以典型住宅建筑为例，提款节点通常包括：楼板或地基完工、框架搭建、屋顶覆盖与防水、内衬与木作、最终完工或合规证书发放。每次提款通常占贷款总额的10%-25%，具体比例取决于合同。
每次提款前，贷款机构要求进行进度检查。独立估价师或贷款机构自身的检查员会到现场确认该阶段基本完成。只有确认后才会放款，通常直接支付给建筑商或划入借款人的贷款账户。
借款人应了解，利息仅按已提取的余额计算，而非全额贷款。早期阶段利息成本较低，随着更多资金被提取而上升。只要借款人对前期首付和可能的费用增加有切合实际的预算，这种结构有助于施工期间的现金流管理。
延误是可能发生的。天气、材料短缺或工匠无法到位都可能使某个阶段超出预期时间。贷款机构可能批准延期，但利息会持续累积。常见做法是预留预备金缓冲: 大多数贷款机构期望至少合同总额的10%-15%作为预备金，具体要求因贷款机构和项目复杂性而异。
从检查到付款，提款通常需要5-10个工作日。建议在下一道工序进场前尽早提交提款申请，以确保施工不中断。
