New year, new goals? How to buy a new home and keep the other as a rental in 2026

What if your next property move didn’t mean saying goodbye to your current home?

As we step into a fresh year, many Kiwis are rethinking their long-term financial goals, and for some, that means turning their existing home into a rental while buying a new place to live.

Whether you're focused on building wealth, creating passive income, or staying connected to the property market, keeping your current home as a rental could be a good idea in 2026.

Here’s what you need to consider:

Why a rental property?

Maybe you’ve outgrown your home, need to relocate, or are simply craving a change of scenery. Holding onto your current property as a rental could offer long-term financial benefits, especially if:

  • You’ve built strong equity in the property
  • The home is in a high-demand or growing area
  • You want to start (or expand) a property portfolio
  • You’re moving away temporarily but plan to return

By retaining your existing home, rental income can help offset the mortgage while you and your whānau start your next chapter. Alternatively, if you’re downsizing or buying something more affordable to live in, you can use the opportunity to let your larger home work for you.

Use your equity to fund your next purchase

One of the most common ways to buy a new home and keep the old one is to tap into the equity you've built. Let’s say:

  • Your home is valued at $650,000
  • Your mortgage balance is $300,000
  • That gives you around $350,000 in equity

Depending on your income, lending criteria, and financial goals, you may be able to use some of that equity as the deposit on your next property - without needing to sell.

At Loan Market Agile, our Christchurch mortgage advisers can help assess your position and determine how much equity you could realistically access.

Rental income 

In many cases, the expected rental income from your current home can help boost your borrowing power for the next one. Lenders usually consider around 70–80% of projected rental income when calculating your affordability. Keep in mind:

  • The rental figure must be realistic: a rental appraisal will usually be required
  • The property must comply with the Healthy Homes Standards
  • You’ll still need to prove you can cover both loans, including during vacancy periods or rate hikes

Deciding which property to live in vs. rent out

This decision will come down to your lifestyle, goals, and the numbers. Consider:

  • Which home better suits your day-to-day needs? (Think: school zones, space, location)
  • Which property offers better rental return or capital growth?
  • Do the numbers stack up more favourably if you live in one over the other?

There’s no one-size-fits-all here; it’s about what aligns best with your long-term vision and what’s financially sustainable in the current market.

Understand the risks and responsibilities

Owning two homes is a big step, and while the potential is exciting, it’s not without its challenges. Ask yourself:

  • Can I comfortably manage both mortgages through market changes or vacancies?
  • Am I prepared to manage tenants, or will I hire a property manager?
  • Do I have a financial buffer for unexpected costs like repairs, maintenance, or rate hikes?

Planning for the “what-ifs” helps ensure you’re not overextending and keeps your investment plan on solid ground.

Get advice early

A lot of careful consideration and planning needs to go into making this work successfully, so get in touch with a mortgage adviser sooner rather than later. Working with the Loan Market Agile team early in the process can help you:

  • Structure your lending for maximum flexibility, cash flow, and tax efficiency
  • Understand how much you can borrow and how to make your equity go further
  • Create a plan that reflects your lifestyle and long-term goals

Is it time to expand your property portfolio?

Whether your New Year goal is to build a property portfolio, create financial freedom, or simply make a smart next step, keeping one home as a rental while living in another could be your perfect next chapter.
