Should you sell your house or rent it out? It comes down to two things: will the rent cover the real costs of owning the house, and do you need the money tied up in it for your next home? Auckland homeowners moving for a new home, a job, a move overseas or to downsize ask me this often. Here are the numbers and questions to look at first.
What rent could my house earn?
The Tenancy Services market rent tool shows the lower, middle and upper rents for homes like yours in your area, based on bond records. It is a good start, but it can't see your home.
For a figure based on your actual home, ask for a free rental appraisal. Get a free sale appraisal at the same time, so you can compare the two.
What does it really cost to be a landlord in New Zealand?
The rent is not what you keep. Before you decide, add up the costs you will still be paying:
- Mortgage repayments, which may change if the bank treats the loan as an investment loan.
- Rates from Auckland Council, plus any body corporate fees.
- Landlord insurance, which is different from a normal house policy and often costs more.
- Repairs and maintenance, from a leaking tap to a new hot water cylinder.
- Property management fees if you pay someone to look after it.
- Empty weeks between tenants, when there is no rent coming in.
Then there are the healthy homes standards. Since 1 July 2025, every private rental must meet them for heating, insulation, ventilation, moisture and drainage, and draught stopping. Each new or renewed tenancy agreement needs a signed statement saying whether the home meets them. Landlords who don't meet the standards can face penalties of up to $7,200, according to Tenancy Services. If your home needs a heat pump, extractor fans or underfloor insulation, that cost comes before the first week of rent.
How is rental income taxed in New Zealand?
I am not a tax adviser, so this is only the broad outline. Please talk to an accountant before you decide.
Rent is taxable income, and you can generally claim costs such as rates, insurance, repairs, agent fees and interest. According to Inland Revenue, you can claim 100% of the interest on money borrowed for a residential rental from 1 April 2025. If your costs are more than your rent, the loss generally can't be used to lower the tax on your wages. It is carried forward to future years instead.
Selling later can also have tax effects. For property sold from 1 July 2024, the bright-line test is 2 years. There is a main home exclusion, but under Inland Revenue's rules it only applies if more than half of the land was used as your main home, and it was your main home for more than half of the bright-line period. If it misses either test, the exclusion does not apply at all.
The 7 November 2026 election could also change things. Labour has said that if it is elected, it will bring in a 28% capital gains tax on residential investment property and commercial property from 1 July 2027. The family home would be excluded, and gains made before that date would not be taxed. National has said it opposes the new taxes Labour has proposed. This is a proposal, not law, and the details could change. I explain what the parties have proposed in selling before or after the election.
How does renting out my house affect my mortgage and next home?
This is often what decides it. If you sell, the money from the sale can go towards your next home. If you keep the house, most of that money stays tied up in it, and you will likely carry two mortgages.
If you have plenty of equity, that can work well. If not, it can mean a smaller budget or a bigger loan. My guide to the cost of selling a house in New Zealand will help you work out what you would walk away with if you sell.
Your current loan was most likely set up for a home you live in. Before you sign up a tenant, ask your bank or mortgage adviser:
- Do I need to tell you if the house becomes a rental, and will my rate or terms change?
- How much can I borrow for my next home while I still own this one?
- Can I use the equity in this house towards my next deposit?
Lending rules for investors are tighter than for people buying a home to live in. Under Reserve Bank rules in place since 1 December 2025, only 10% of a bank's new lending to investors can be for more than 70% of the property's value. In plain terms, most investors need a deposit of about 30%.
Can I be a landlord from another city or overseas?
You can, but tenants will call about a broken oven or a leak, and inspections, bond paperwork and finding new tenants all take time. That is harder from another city or time zone. If you are moving overseas and leaning towards selling, read my guide to selling NZ property from overseas.
That is where a property manager helps. Harcourts Reforma has a property management team who can look after tenants, inspections and the healthy homes paperwork for you. Their fee is one of the costs to add to your list.
Should I sell or rent out? Questions to help you decide
Answer these for both choices, side by side:
- After all costs, does the rent cover the mortgage, or will I be topping it up each week?
- Do I need the money from this house for my next deposit?
- How long do I plan to keep it, and what does my accountant say about tax when I sell?
- Does the house meet the healthy homes standards, and what would it cost if not?
- Am I happy to be a landlord, or to pay someone to do it for me?
- Would I buy this house today as an investment if I didn't already own it?
If the answer to that last one is no, selling may be the simpler choice.
Where to from here?
The best way to decide is with real numbers for both choices. I can give you a free appraisal of what your home might sell for, and our property management team can give you a free rental appraisal. Put the two figures side by side with your accountant's advice. Start with a free property appraisal or get in touch for a no-pressure chat.
Questions homeowners ask me about selling or renting out
Is it better to sell my house or rent it out?
It depends on whether the rent covers all the costs of owning it, and whether you need the money in it for your next home. If you would not buy the house today as an investment, selling may be the simpler choice.
Can I rent out my house while I decide whether to sell?
Yes, but a tenancy can make a later sale slower, as tenants need proper notice and viewings must work around them. If you might sell within a year, decide before you sign a tenancy. My guide to selling a tenanted property explains the notice rules.
How do I find out what rent my house would get?
Start with the free market rent tool on the Tenancy Services website, which shows rents for your area from bond records. Then get a free rental appraisal, which looks at your actual home, its condition and what is renting nearby right now.
Do I have to meet the healthy homes standards before I rent it out?
Yes. Since 1 July 2025 all private rentals must meet the healthy homes standards for heating, insulation, ventilation, moisture and drainage, and draught stopping. Every new or renewed tenancy agreement must include a signed statement about the home's compliance.
Will I pay tax if I sell my house after renting it out?
It depends on when you bought it, how long it was your main home and the reason you bought it. The bright-line test is 2 years for property sold from 1 July 2024. The main home exclusion only applies if more than half of the land was your main home for more than half of that time. An accountant can tell you how it applies to you.
