A key election issue is whether the Labour party will reverse the full interest deductibility for landlords, which was recently restored by the National-led government. Reverting the policy would increase landlords' tax obligations.

Experts are divided on the potential impact. Some predict slightly lower house prices over time and argue rents are driven by supply and demand. Others warn landlords may be forced to sell or increase rents to cover higher costs.

A potential compromise is a "middle path" allowing 50% deductibility.
