Turnover is the most expensive thing happening in a small portfolio, and it is almost entirely preventable.

Count what one turnover costs. Weeks of vacancy. Cleaning and paint. Photography and advertising. Your hours on showings, applications and screening. A screening report. Then the risk you replace a known good tenant with an unknown one.

On a $1,900 unit, a straightforward turnover runs into thousands of dollars and a couple of dozen of your hours. A tenant staying a fourth year instead of leaving after three is the highest-return thing you do all year, and it does not require a rent discount.

Our tenant onboarding post covers the first thirty days. This covers everything after.

What makes tenants leave

Rent is the reason people give. It is rarely the reason.

Tenants leave because of life events you cannot control: a job, a relationship, a baby, a house purchase. Nothing to do there.

And they leave because of things you control entirely. Repairs taking too long or never happening. Feeling ignored. A landlord who only makes contact to raise the rent or complain. Entry without notice. Being treated as a problem rather than a customer.

The second list is where retention lives.

The four habits

• Acknowledge fast, always — not fix fast, since parts and trades take time. Acknowledge. Every message gets a reply within hours with a next step and a date. The tenant told a plumber is coming Thursday waits patiently. The tenant hearing nothing decides you do not care, and the decision is what surfaces at renewal.
• Keep one channel — texts to your personal phone, emails, calls, and notes under the door mean things get lost and neither party has a record. One channel, timestamped, both sides seeing the same history. This is as much protection for you as convenience for them.
• Follow the rules on the small things — proper notice for every entry, every inspection, every increase. A landlord who gives 24 hours notice for a furnace filter change is a landlord a tenant believes on the larger issues.
• Do what you said — most tenant complaints are not about the state of the unit. They are about a promise nobody kept. If you cannot do it, say so and say why. Saying so beats silence.

The annual cycle

Four touchpoints a year, none of them long.

• Spring, the seasonal check — you are servicing the air conditioning anyway. Ask what needs attention while you are there. Fix one small thing you find, even if nobody asked.
• Summer, the quiet month — nothing, deliberately. A landlord who contacts a tenant only when something is needed trains them to dread the notification.
• Fall, the heating service — same pattern as spring. Furnace serviced, filters changed, and a question about how the unit is working.
• 90 days before the lease anniversary, the renewal conversation — the most important one.

Four touches a year plus whatever maintenance arises. It is not a relationship-building programme. It is enough contact for the tenant to know someone is paying attention to the place they live.

The renewal conversation

Have it 90 days out, before the notice period forces it.

• Ask first, tell second — open with a question about how things are going and whether anything needs attention. Then talk about terms. Landlords opening with the rent increase get a negotiation. Landlords opening with the question get information.
• Fix what surfaces — a tenant naming two small things at renewal is handing you the reason they might leave. Fixing both is cheaper than a turnover by an order of magnitude.
• Be straightforward about the increase — where you are raising rent, say the amount, the effective date, and briefly why. Rising taxes, insurance, an improvement you made. Tenants accept an explained increase far more readily than an unexplained one.
• Understand the arithmetic before you set the number — a $75 monthly increase produces $900 a year. A turnover triggered by it costs several times as much in vacancy, work and hours, and hands you an unknown tenant. None of which means never raise rent, since a unit drifting below market becomes a problem of its own. It means the number is a business decision with two sides, not an automatic maximum.
• Where you are staying at the same rent, say so explicitly rather than letting the anniversary pass in silence. It reads as a decision rather than an oversight, and it is worth goodwill.

Follow your province's rules. Alberta requires 365 days between increases with three months notice for a monthly tenancy. BC caps 2026 increases at 2.3% with three months notice on form RTB-7. Ontario's 2026 guideline is 2.1% with 90 days notice on form N1, unless the unit is exempt from rent control. Our rent increase rules post has the detail.

The things worth doing at almost no cost

A small unprompted improvement every year or two — new blinds, a better light fixture, a fresh coat in one room at renewal. Cheap, visible, and it signals the place is cared for.

A response to a repair request faster than the tenant expected. A note when they have been there a year. Flexibility on the small stuff — a moving date shifted by a few days, a guest staying a month, a rent date moved to line up with a pay cycle.

None of this is generosity. It is the cheapest retention spend available, and it competes against a four-figure turnover cost.

What to measure

Two numbers, per unit, per year.

• Average tenancy length — the single best indicator of how your portfolio is running.
• Renewal rate — the share of tenancies renewing rather than ending by tenant choice. Track it, because a decline shows up here before it shows up in your income.

If one unit consistently turns over faster than the others, the problem is the unit, the price or the neighbours, not the tenants. The finding is fixable, and it is invisible without the numbers.

LuxOasisOS gives every tenant direct messaging with automatic reminders and their lease on file, so the communication history lives in one place and nothing depends on anyone's memory.
