New Build Lending: What Your Clients Need to Understand

New build lending is an area that trips up even experienced borrowers if they are not well prepared. The process is meaningfully different from purchasing an existing property - from how the loan is structured and drawn down, to how valuations work, to what happens if the build takes longer than expected. As a broker, helping clients understand these differences before they sign a build contract is one of the most valuable things you can do to prevent problems further down the track.

How New Build Lending Works

When a client purchases a new build property (whether house and land, townhouse, or apartment off the plan), the loan is typically not advanced in a single payment at settlement. Instead, funds are drawn down progressively as the build reaches defined milestones - for example, at completion of the slab, frame, lock-up, and final fit-out. This progressive drawdown structure means the client is paying interest only on the amount drawn at each stage, rather than on the full loan amount from day one.

The implication is that the client's repayments during the build period will be lower than their eventual full repayment, but they may also be paying rent or another mortgage simultaneously. Brokers should work through the full cash flow picture with clients to ensure they can genuinely manage the build period without financial stress - particularly if the timeline extends beyond the original estimate.

Valuation and LVR Considerations

Lenders will typically require a valuation of the completed property before or during the loan approval process. For off-the-plan purchases, this can be challenging because the property does not yet exist. Lenders generally use an as-if-complete valuation, which estimates the property's value upon completion. If market conditions change significantly between the time of signing the purchase agreement and completion, the as-if-complete value at settlement may differ from the original estimate.

This creates a potential LVR risk: if the property values below the purchase price at completion, the client may need to contribute additional funds to meet the lender's LVR requirements. Brokers should discuss this scenario with clients upfront, particularly in markets where values are less certain. Understanding the client's ability to bridge any potential valuation shortfall is part of a thorough pre-application assessment.

New Build LVR Exemptions

New builds benefit from a specific exemption under the Reserve Bank's LVR restrictions, allowing lenders to lend at a higher LVR (lower deposit) for new builds than for existing properties. This is a genuine advantage for clients with smaller deposits and is one of the factors that makes new builds particularly attractive for first home buyers. Brokers should understand the current exemption parameters and how they interact with any applicable government schemes such as the First Home Loan.

The exemption applies to new builds as defined under RBNZ rules, and the definition has specific requirements. Not every property marketed as a new build will necessarily meet the criteria for the exemption, so it is worth confirming eligibility with the lender early in the process rather than assuming it applies.

Build Contracts and Pre-Approval Limitations

Pre-approval for a new build comes with a shelf life and limitations that are worth explaining to clients clearly. Most pre-approvals are valid for a defined period (often 60 to 90 days), and a new build that takes 12 to 18 months to complete will require the pre-approval to be refreshed and the client's circumstances to be reassessed at completion. Changes in the client's income, employment, or financial position during the build period can affect their ability to settle.

Clients should also understand that pre-approval is not a guarantee of final approval at completion. Final approval is typically subject to a satisfactory valuation of the completed property and confirmation that the client's circumstances remain as declared. Setting this expectation at the outset prevents the client from being blindsided if circumstances change during the build period.

Working Through Complexity Together

At Chaperone, we help brokers manage the longer timelines and more complex documentation requirements that come with new build lending. Keeping a new build application well-organised over a multi-month period - tracking key dates, managing condition expiries, and ensuring clients remain informed - is where the broker relationship really earns its value.
