This estimate assumes a constant interest rate over the full term. Your lender confirms the actual rate and loan conditions.
Enter the building cost, deposit, interest rate and loan term to estimate repayments. Your lender confirms the available rate and loan terms.
Estimates only, not lending advice. Your lender confirms the interest rate and terms. The rental comparison uses $600/week for a two-bedroom home in regional New Zealand; actual rent varies.

Rents are indicative planning figures for a warm, compliant two-bed minor dwelling. Verify against Tenancy Services bond data for your suburb. Gross margin before rates, insurance, maintenance and vacancy.
Three common ways owners structure their borrowing. These examples are not financial advice.
Lending rules, rates and tax treatment change and differ by person. Confirm anything that matters with your bank, broker or accountant before committing.
Possible options include a mortgage top-up, a construction loan or a combination of savings and borrowing. Ask your lender or adviser which options are available for your circumstances. The calculator estimates repayments; it does not assess loan eligibility.
Compare the rent you expect with repayments and all other ownership costs. Rates, insurance, maintenance, management fees, tax and periods without tenants affect the amount available. Rental income and borrowing costs can change.
Your lender assesses your income, debts, property value, available equity and its lending criteria. The deposit slider shows how a contribution changes the estimated loan repayments; it does not indicate an approval threshold.
Ask your lender for its requirements. These may include signed plans, a construction contract or quote, valuation information and evidence of the required approvals. Seventy supplies the plan set; your builder supplies the construction quote.
Compare the options with your lender or adviser, including fees and conditions. You can change the calculator’s interest rate to see how repayments change, but it does not predict future rates.
The effect on value depends on the property, completed home and local market. A registered valuer can assess the proposal. Do not assume that the increase in value will equal the cost of construction.
