We own our home and are buying our first rental property. What matters most to us is getting good help and advice when we need it. Which lenders would you recommend for the rental property loan, and why?
Since you already own your home and this is your first rental property, I would put less weight on finding the absolute lowest interest rate and more weight on finding a lender that will help you structure the lending well, explain options, and support you as your situation evolves.
In New Zealand, I’d shortlist these lenders first:
1. BNZ — strongest all-round choice for a first-time investor
Why I’d consider them:
- They have a dedicated property investment focus and resources for people buying their first rental. BNZ
- Their loan products can suit investors who want flexibility, including options such as interest-only and offset-style features. Canstar
- They have scored strongly in independent comparisons for investment lending and customer satisfaction. Canstar
Best fit if you want:
- A lender that understands property investors.
- Good online tools and reasonably straightforward processes.
- Advice as you potentially buy more properties later.
Potential downside:
- A big bank experience can sometimes feel less personal than a smaller lender or a good mortgage adviser relationship.
2. ASB Bank — strong for service and investor lending
Why I’d consider them:
- ASB has performed well in investment lending comparisons, including recognition for investment loan value. Canstar
- They have a large home lending team and established systems for managing property loans.
Best fit if you want:
- A major bank with a strong support network.
- Someone to guide you through the first investment purchase.
- A lender you may already have a relationship with.
Potential downside:
- Like other large banks, the quality of your experience can depend heavily on the individual adviser or lending manager you get.
3. Kiwibank — worth considering if values and local ownership matter
Why I’d consider them:
- They have specific investment property lending guidance and encourage investors to work with specialists through the process. Kiwibank
- Some borrowers prefer dealing with a New Zealand-owned bank.
Best fit if you want:
- A more locally focused lender.
- Straightforward banking alongside your mortgage.
Potential downside:
- Depending on your circumstances, they may not always be the most flexible lender for complex investor structures.
4. ANZ New Zealand — good if you value a large lending network
Why I’d consider them:
- They have specialist support for property investors and mortgage managers who work with investment buyers. ANZ Bank
- Their scale can be useful if your finances become more complex.
Best fit if you want:
- A large bank with broad capability.
- Face-to-face or phone-based support.
Potential downside:
- Large organisations can vary in responsiveness depending on the person handling your application.
My shortlist for your situation
If I were narrowing this down for a first rental purchase where good advice matters most, I would probably start with:
- BNZ — my first conversation
- ASB — very close second
- Kiwibank or ANZ — as comparison options
I would also strongly consider using a good mortgage adviser (broker) rather than approaching only one bank. A broker can compare lenders, help structure how your existing home debt and new rental debt are separated, and sometimes access lenders or deals you may not approach directly.
Questions I would ask any lender/adviser before choosing
- How will you structure our existing home loan versus the rental loan?
- How much of our rental income will you count when assessing borrowing ability?
- Would interest-only lending make sense for the investment portion?
- What happens if we want to buy a second rental in 2–5 years?
- What are the costs if we sell, refinance, or change loan structure?
- Who will actually look after us after settlement?
One important point: because you already own a home, the loan structure can matter as much as the lender. The “best” lender may not be the one with the lowest advertised rate if the structure makes future borrowing harder.
If you share your rough situation (house value, remaining mortgage, rental purchase price, deposit available, and whether you want a long-term hold or future portfolio), I can suggest which lender type is likely to suit you best.
