Looks like PR will do...Who qualifies?
If you're borrowing either on your own or with one other person, your household income can be up to $85,000. Or if you're borrowing with two or more people, your household income can be up to $120,000.
You'll need to be a New Zealand Resident or Citizen and not already own a home. You'll also need to have an acceptable credit history, and you'll be required to live in the house you buy for the life of the loan.
