What is the main difference between a turnkey and a construction loan?
A turnkey property is purchased as a fully completed package; you pay a deposit upfront and the remaining balance only upon settlement when the house is finished. A construction loan requires you to purchase the land first and then make progressive "drawdown" payments to a builder as they hit specific construction milestones.
What is the "Overlap Penalty" when building a house?
The overlap penalty occurs during a construction loan when you must pay your normal living rent at the same time as paying mortgage interest on the land and the progressive build stages. Because the house isn't finished yet, you are paying for two places to live simultaneously. Turnkey homes avoid this penalty because you do not pay the mortgage until you move in.
Why do turnkey homes cost more upfront?
Turnkey homes have a higher sticker price because the property developer bears all the financial risk and holding costs. The developer pays the interest on the construction loan, manages council delays, and absorbs the risk of material price increases. They bake these holding costs, along with their profit margin, into the final sale price.
What deposit is required for a turnkey vs. construction loan in NZ?
In New Zealand, banks generally require a 10% deposit for a turnkey property (or 5% if using the Kāinga Ora First Home Loan scheme). Construction loans outside of Kainga Ora First Home Loan are considered higher risk and typically require a 20% deposit against the land purchase, and an overall deposit equating to at least 10% of the total project cost.
