Is a rental a good investment in 2026? It's a calculation, not a camp
Property bulls and bears both argue vibes. Your answer lives in five numbers specific to the deal in front of you.
The five numbers that decide it
Weekly cashflow after all costs at today's rates; break-even rent (how far rents could fall before you bleed); the +2% rate stress result; total return under conservative growth (not the agent's brochure number); and your hold horizon versus bright-line. A deal that survives all five is investable regardless of headlines; one that fails two deserves a pass regardless of FOMO.
What 2026 changes about the maths
Interest deductibility restoration improved after-tax cashflow versus the 2021–23 squeeze; rates off their peak improved serviceability; but prices in most centres still put gross yields below mortgage rates — meaning most purchases start cashflow-negative and are growth bets at heart. Regions differ enormously: the same $650k buys a negative-cashflow Auckland unit or a neutral Invercargill duplex.
The risks people under-model
Vacancy longer than the two weeks everyone assumes; the $15k roof year; body corp special levies; a tenant who stops paying (months to resolve); and rate refix shock — the 2021 buyers refixing from 2.5% into 7% learned this one publicly. Stress tests aren't pessimism, they're the price of using leverage.

Is now a good time to buy a rental in NZ?
Market timing is the least controllable variable; deal quality is the most. A good deal at an average time beats an average deal at a good time.
How much deposit do I need for a rental?
Investor lending typically requires ~30-35% for existing homes (less for new builds) under LVR settings — and the deposit size drives your cash-on-cash return, so model it, don't just clear it.
Can I stress-test a deal before offering?
That's exactly the point of Deal Analyser — the +1%/+2% rate stress and break-even rent are computed on every run. First one free.
