Your bank can only offer its own products, assessed against its own policies. For owner-occupied homes, that’s often fine. For property investment finance, it’s more limiting, as lenders vary considerably in how they treat rental income, what deposit levels they’ll accept, and how flexible they are with portfolio structures.
Working with a mortgage advisor (or property finance broker in Auckland or Hamilton) means your situation gets assessed across the full market. Whether you’re based in the Waikato or are looking for a mortgage broker in West Auckland, Innovest’s advisors do that comparison on your behalf.
