Is a Higher Rent Worth Waiting For? Calculate the Cost of a Vacancy

The short version: At $600 a week, a single empty week costs $600 in gross rent. Waiting for $20 more per week needs 30 occupied weeks to recover that one week, assuming the higher rent is secured immediately and ignoring other costs. The 9 October 2026 rent report said the national median for newly tenanted homes was $595 in August, unchanged from a year earlier, while fewer properties were newly tenanted than in July.

I own rentals and have had to decide whether to hold out for a higher rent or choose a suitable tenant at the asking price. The answer depends on local comparables and the cost of waiting, not one national median. The Tenancy Services market-rent tool uses recent bond information as a guide. Check its dates and property filters before comparing.

How do I calculate the cost of one vacant week?

Start with weekly rent and the likely time empty. At $600 per week, two vacant weeks mean $1,200 in gross rent not received. That is a simple comparison, not a full cash-flow forecast: rates, insurance, utilities, advertising, cleaning, repairs and any changeover costs continue or may arise while the property is empty.

Then compare the vacancy cost with the extra rent you hope to achieve. Divide the amount lost during the vacancy by the weekly increase:

Break-even occupied weeks = vacant-week rent lost ÷ proposed weekly increase.

For example, $600 divided by $20 is 30 weeks. If the higher rent takes two weeks to secure, you need 60 occupied weeks at the extra $20 just to recover the $1,200 gross rent lost. A longer wait pushes the break-even point further out.

Does flat national rent data mean my rent is too high?

No. National figures provide context, not a valuation of one house. The August 2026 figures reported by interest.co.nz combine a national median and activity counts. Stats NZ's separate August selected price indexes showed the stock measure of rent unchanged over the year and the flow measure for new tenancies up 0.9 percent. These series describe different parts of the market.

Check properties similar to yours by location, dwelling type, bedrooms, condition and included features. Tenancy Services explains that its market-rent figures use bonds lodged in a recent six-month window and should be treated as a guide. Compare the data period, current asking rents and recent tenant interest. Asking prices show what landlords request, not necessarily what a new tenant agrees to pay.

When might it make sense to wait for a higher rent?

Waiting may be reasonable when recent local evidence supports the higher amount, enquiries are active, and the likely time to secure a tenant is short. A material gap between your asking rent and comparable homes, repeated viewings without suitable applicants, or a long marketing period can point the other way. Recheck the property presentation, availability date and advertisement as well as the rent.

There is no certain way to predict how quickly a tenant will sign. Use a few realistic timing scenarios. Compare one week empty, several weeks empty and a longer vacancy against accepting a lower rent now. Include the cost of changing tenants and the value of keeping a suitable tenant if you are reviewing rent during an existing tenancy.

Can I offer a lower rent to fill the property or raise it later?

You can agree a rent with a new tenant, subject to the law and the tenancy agreement. Once a tenancy begins, the statutory timing and notice rules apply to rent increases. A landlord generally cannot increase rent within 12 months of the tenancy starting or within 12 months of the last increase taking effect, and at least 60 days' written notice is required. Check the current Tenancy Services rent-increase guidance before serving notice.

Do not treat a mortgage payment, rates rise or insurance renewal as an automatic right to increase rent by the same amount. Check the tenancy type, agreement, effective dates and current law for your circumstances.

What should I record before deciding on the rent?

1. Save the date and source of each comparable, including property type, bedrooms and condition.
2. Record the asking rent, enquiry and viewing activity, and any feedback that affects the decision.
3. Write down the expected vacancy length and calculate the cost at more than one scenario.
4. Keep the agreed rent and effective date with the tenancy schedule, then review the outcome after letting.

What can go wrong if I focus only on the weekly rent?

A high asking rent can look good in an advertisement while an extended vacancy reduces the year's actual income. A low asking rent can also leave money on the table if it is unsupported by local evidence or if the property could be improved at a sensible cost. Compare annual rent received after vacancy and changeover costs, not just the weekly figure, and do not rely on one national statistic to decide.
