Build finance needs to match the progress of the build.建筑贷款需要匹配工程进度。

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.

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。

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.

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。

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.

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。

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.

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。

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.

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。

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.

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。

Cost overrun — what to plan for before starting

成本超支——开工前应做的规划

Cost overruns are the single most common cause of stress in construction projects. Lenders assess overrun risk before approving a loan, and borrowers who plan for it upfront save themselves significant financial pressure.

成本超支是建筑项目中最常见的压力来源。贷款机构在批准贷款前会评估超支风险，提前做好规划的借款人可以避免巨大的财务压力。

A cost overrun happens when actual building costs exceed the budget agreed in the building contract. Common sources include unexpected ground conditions such as poor soil requiring deeper foundations, variation orders requested by the owner mid-build, price increases for materials between quoting and procurement, and delays caused by weather or consent issues that lead to extended project management fees.

成本超支是指实际建筑成本超过建筑合同中约定的预算。常见原因包括：意外的地基条件（如劣质土壤需要更深处的基础）、业主在施工中提出的变更指令、材料从报价到采购期间的价格上涨，以及天气或审批问题导致的延误，进而产生额外的项目管理费用。

Lenders typically require borrowers to hold a contingency buffer. For a standard residential build this is often 10-15% of the contract sum. For developments with more unknowns — such as steep sites, heritage buildings, or multi-unit projects — 15-20% may be more appropriate. This contingency is usually funded from the borrower's own equity rather than borrowed funds, though some lenders allow it to be included in the loan structure if supported by sufficient equity.

贷款机构通常要求借款人持有预备金缓冲。对于标准住宅建筑，通常为合同金额的10%-15%。对于存在更多不确定因素的开发项目——如陡峭地块、历史建筑或多单元项目——15%-20%可能更为合适。预备金通常由借款人自有的净值提供，而非借入资金，但部分贷款机构允许在净值充足的情况下将其纳入贷款结构。

If an overrun occurs and the contingency is exhausted, the options are limited. The borrower may need to contribute additional cash, seek a supplementary loan (which requires lender approval and often updated valuations), or pause the project until more funding can be arranged. None of these are straightforward mid-construction.

如果发生超支且预备金用尽，可选择的方案非常有限。借款人可能需要追加现金、申请补充贷款（需要贷款机构批准和通常更新的估值），或暂停项目直至筹集到更多资金。这些在施工中期都不是简单的事情。

A practical approach is to obtain fixed-price contracts where possible. While not all builders offer fixed pricing for the full scope, a fixed-price contract for the main structural and finishing work reduces the risk of surprises. Where a contract is on a cost-plus or provisional-sum basis, borrowers should budget at least 20% above the estimate.

一个实用的方法是在可能的情况下采用固定价格合同。虽然并非所有建筑商都为全部范围提供固定价格，但主要结构和装修工程的固定价格合同可以减少意外风险。如果合同是成本加成或暂定金额性质的，借款人应按估算金额至少上浮20%做预算。

Getting a quantity surveyor's report before applying can also help. Many lenders require one for projects over a certain value, and it provides an independent view of likely costs rather than relying solely on the builder's quote.

在申请前获取工料测量师报告也有帮助。许多贷款机构要求达到一定金额的项目提供该报告，它能提供对可能成本的独立看法，而非仅依赖建筑商的报价。

Building contract types and their impact on financing

建筑合同类型及其对融资的影响

The type of building contract you sign affects not only your legal obligations but also how a lender views your construction loan application. Lenders assess risk differently for each contract type, and this can influence the loan amount, the drawdown schedule, and the conditions attached.

你所签署的建筑合同类型不仅影响你的法律责任，还影响贷款机构如何看待你的建筑贷款申请。贷款机构对每种合同类型的风险评估不同，这会影响贷款金额、提款计划以及附加条件。

Fixed-price contracts are the most common for residential construction. The builder agrees to complete the stated scope of work for a set price. Lenders generally prefer these because the total cost is known, making it easier to calculate loan-to-value ratios and contingency requirements. The risk falls mainly on the builder if material prices rise. However, fixed-price contracts often exclude provisional sums for items like kitchen joinery or flooring, so borrowers need to check what is actually included.

固定价格合同在住宅建筑中最常见。建筑商同意以固定价格完成约定的工程范围。贷款机构普遍偏好这种合同，因为总成本明确，更容易计算贷款价值比和预备金要求。如果材料价格上涨，风险主要由建筑商承担。但固定价格合同通常不包含厨房木作或地板等项目的暂定金额，因此借款人需要核实实际包含的内容。

Cost-plus contracts charge the borrower for actual labour and materials plus a builder's margin. Lenders view these as higher-risk because the final cost is uncertain. Some lenders decline cost-plus contracts outright; others require a detailed cost estimate and a higher contingency, often 20-25%. Interest-only drawdowns may also be restricted, and the lender may cap total lending at a lower percentage of the completed value.

成本加成合同按实际人工和材料费用加上建筑商的利润向借款人收费。贷款机构认为此类合同风险较高，因为最终成本不确定。有些贷款机构直接拒绝成本加成合同；其他机构则要求提供详细的成本估算和更高的预备金，通常为20%-25%。仅付利息的提款也可能受到限制，贷款机构可能会将贷款总额上限设定为完工价值的较低比例。

Fixed-price with rise-and-fall clauses allows the contract price to adjust for specified cost increases, usually tied to an index such as construction cost inflation. Lenders treat these similarly to pure cost-plus arrangements for risk assessment purposes, as the final price is not guaranteed. Borrowers should expect the same tighter conditions.

带涨跌条款的固定价格合同允许合同价格根据特定成本增长进行调整，通常与建筑成本通胀等指数挂钩。贷款机构在风险评估方面会将这些合同与纯成本加成安排同样对待，因为最终价格无法保证。借款人应预期相同的更严格条件。

Design-and-build contracts cover both design and construction under a single agreement. Lenders often appreciate the single-point responsibility, but they still review whether the design and specifications are detailed enough to support a fixed price. If the contract is vague on materials or finishes, the lender may treat it as a cost-plus arrangement.

设计与施工总包合同将设计和施工涵盖在单一协议中。贷款机构通常赞赏这种单一责任制，但仍会审查设计和规格是否足够详细以支持固定价格。如果合同在材料或装修方面含糊不清，贷款机构可能将其视为成本加成安排。

Before signing any contract, borrowers should ask their lender which contract types they accept and what conditions apply. Having a contract form that the lender is comfortable with — such as NZS 3910 or a standard Master Builders form — can smooth the approval process.

在签署任何合同之前，借款人应询问贷款机构接受哪些合同类型以及适用哪些条件。使用贷款机构认可的合同格式——如 NZS 3910 或标准的 Master Builders 合同——可以使审批过程更顺畅。

Often through progress payments as stages are completed, subject to lender and valuation requirements.

通常按工程阶段进度放款，具体取决于贷款机构和估值要求。

Many lenders prefer clearer contract certainty. Other structures may need more evidence or buffer.

很多贷款机构偏好更确定的合同。其他结构可能需要更多证明或缓冲。

You may need contingency, extra equity, or a revised plan. It is better to plan for this early.

可能需要预备金、额外净值或修订计划。最好提前规划。

如果贷款是关键，最好在合同和时间安排锁定太深前申请或评估。
