How to Screen for Tenants Likely to Renew Long-Term

Every time a tenant moves out, I lose about ¥180,000 in cleaning, repainting, ad fees, and vacant days before the next lease starts. After self-managing 9 rental units for over 15 years, I have learned that the real profit driver is not filling a vacancy fast, it is filling it with someone who stays. A tenant who renews for 3 or 4 years running is worth more to me than three separate tenants who each last 12 months.

So these days, before I even hand over an application form, I am screening for one thing above everything else: does this person look like they will still be here in 36 months. Here is exactly how I sort that out, using nothing fancier than a printed application, a phone call, and about 20 minutes of my time per applicant.

Why Turnover Costs More Than People Assume

New landlords tend to price a vacant unit and stop there, but the real cost stacks up fast. On a typical 1K unit I manage, I am looking at roughly 2 weeks of lost rent, ¥60,000 in cleaning and wallpaper touch-ups, and another ¥40,000 in agent commission to refill it. Multiply that by a building with high turnover and you can lose an entire month of net profit across the year without a single major repair happening. Once I started tracking this in a spreadsheet, screening for renewal likelihood stopped feeling optional, and it changed how I read every application that lands on my desk.

I also factor in the wear on the unit itself. Every move-out means checking the tatami mats or flooring, testing the water heater, and usually finding at least one small fix that a long-term tenant would have simply mentioned in passing rather than leaving for the final walkthrough. Over 15 years I have come to see a high-turnover unit as a maintenance problem wearing a vacancy costume.

Ask About Their Timeline Before Their Income

Most landlords lead with income verification. I lead with a simple question: what is bringing you to this area, and how long do you expect to be here. A transfer employee on a 2-year rotation, a student in a 4-year program with 3 years left, or a new graduate testing out a first job all answer differently, and the answer tells me more than a pay stub does. I am not disqualifying short-term renters outright, since I still need to fill units, but I weight their applications differently and I am upfront that shorter leases may carry a smaller renewal discount.

Look Past the Credit Score to the Pattern

A credit score tells you whether someone pays bills, not whether they put down roots. I ask every applicant for their last 2 addresses and how long they lived at each one. Someone who stayed 3-plus years at their previous two places is, in my experience, roughly twice as likely to renew with me as someone who has moved every 10 to 12 months for the past 3 years. I also call the previous landlord directly rather than relying on a written reference letter, since a 5-minute phone conversation usually reveals more about how someone actually lived in a unit.

My Actual Screening Checklist

Over the years I have narrowed this down to a short list I run through for every serious applicant. It is not complicated, but skipping even one step has cost me a bad tenant before.

• Confirmed reason for moving and expected length of stay at the new unit
• Previous landlord phone call, not just a letter, covering at least the last 2 years
• Income at least 3 times monthly rent, verified with a recent pay slip
• Address history for the last 5 years, checking for a pattern of short stays
• A face-to-face or video walkthrough of the unit before signing, not just photos
• Clear explanation of the 2-month security deposit and renewal terms up front

Small Signals That Predict a Long Stay

Some of the best predictors have nothing to do with paperwork. Applicants who ask detailed questions about the neighborhood, nearby schools, or garbage collection days are usually planning to settle in, not pass through. Applicants who show up on time for the viewing and follow up with a thank-you message within a day or two tend to be more conscientious tenants overall, in my experience across roughly 60 leases signed since I started. On the flip side, someone who negotiates hard on move-in costs but shows no interest in the area itself is often thinking short-term, even if they never say so directly.

I keep a simple 5-point mental scorecard while I am chatting with applicants: reason for moving, interest in the neighborhood, punctuality for the viewing, tone of their follow-up message, and how they talk about their current landlord. Someone who badmouths every previous landlord in detail is usually going to have a lot to say about me too, eventually. It is not a scientific method, but after roughly 60 leases it has been a more reliable predictor than the credit score alone.

What I Do Once the Lease Is Signed

Screening only gets you the right tenant, it does not keep them. I send a short check-in message around the 3-month mark asking if anything needs attention, and I respond to repair requests within 48 hours whenever possible. Tenants who feel heard early tend to renew without me having to ask twice. Across my 9 properties, units where I do this consistently now average close to 3.5 years per tenancy, compared to under 18 months on the units where I used to skip it.

That is the approach I use across all 9 of my properties, and it is the single biggest reason my vacancy costs have dropped year over year without me raising rents aggressively to compensate.
