of new monthly residential mortgage lending going to property investors

Four steps before bidding.
Investor LVR rules and stress-test servicing are tighter than owner-occupier. Get pre-approval before bidding.
Standalone vs cross-collateralised. Personal name vs trust vs LTC. Get accountant advice early.
IO improves cash flow short term but pays more interest over the life. Match to your strategy.
Investor pricing and servicing varies significantly between banks and non-banks. Use a broker if comparing more than two.
Investor lending finances residential or commercial property held for rental income and/or capital growth. NZ rules treat investor mortgages differently from owner-occupier — LVR speed limits, servicing tests, interest deductibility and the brightline test all apply differently. Banks dominate the bulk of investor lending; non-bank specialists pick up cases with non-standard income or borrowing structure. Choosing the right structure (personal name vs trust vs LTC, standalone vs cross-collateralised) has long-term tax and asset-protection consequences.
Compare carded rates, post-negotiation rates, cashback (if any), interest-only term, and the servicing assessment. Get accountant advice on structure before applying. Use a specialist investor mortgage adviser if you are building a portfolio — they know which banks accept which structures.

Owner-occupier rules differ from investor rules. Investor lending typically requires a higher equity stake than owner-occupier — the RBNZ's loan-to-value-ratio (LVR) speed limits vary over time. Recent settings require investors to hold a meaningful equity portion. Confirm current LVR rules with the lender at quote time.
Yes, most banks offer interest-only for a fixed period (commonly 5 years) on investor loans, then revert to principal and interest. Interest-only helps cash flow but increases total interest paid over the life of the loan.
The brightline test treats profit on residential property sold within a set holding period as taxable income. Holding period and exemptions have changed multiple times — confirm the current rule with your accountant at purchase and sale.
Interest deductibility for residential investors has changed multiple times in recent years. The current rules depend on property type (new build vs existing) and date acquired. Confirm with your accountant before relying on a specific position.
Yes, "cross-collateralisation" or "top-up against the home" is the standard approach. The lender treats both properties as security. Risk: a downturn affects both. Standalone investor loans (each property securing only itself) are safer but harder to structure.
Banks stress-test all lending at a rate above the carded rate. For investors, they typically include rental income at a discounted percentage to account for vacancy and costs. Conservative tests can reduce borrowing capacity sharply.
Most banks lend to trusts but require trustees to back the loan personally. Some structures (look-through companies) get standard lending. Complex structures can extend application time.
Most investors benefit from a specialist mortgage adviser who has placed investor cases across multiple banks. The right structure can mean a significant difference in borrowing capacity and lifetime interest cost.
